BACKGROUND OF THE INVENTION
This invention relates itself to the improvement in the method of remote
control by demodulation and modulation for providing information on a
baseband format and for varying information and functions to remodulate
and transmit the signal to a remotely located receiver without connections
or modifications to the receiver and the electronic guided remote control
device and apparatuses employable with the same.
DESCRIPTION OF PRIOR ART
To understand more fully the vast improvement inherent in the innovative
method of remote control by means of demodulating and modulating carrier
waves, it behooves us to elucidate the basic theory and features of remote
control methods found in prior art and compare the prior art methods with
the improved method. Though the various methods may vary somewhat, one
basic underlying theory is common to all and that theory relates to the
following: The implementation of remote control of a device's functions by
moving or changing specific parts in the device's receiver; different
control parts are required to be built into specific components of the
television to enable the user to exercise remote control on every other
function of the television such as volume control, contrast, color
intensity or mixings. Operating in accordance with this prior art theory
for remote control, the current methods of remote control could control
only a television that has these control parts built in. It cannot
exercise remote control on television sets of other company brands,
outdated television sets or differently built television units. It cannot
exercise remote control, whatever, on any television set whatever, that
did not have similar control parts built in. It certainly could not
control radio receivers, that did not have control parts built in.

A Model 5, E.G.R.C. device may be constructed by combining the circuitry,
electronic components and parts found in Model 1 with the electronic
components and parts found in Model 3, E.G.R.C. device. This combination
of circuitry and parts would enable Model 5, E.G.R.C. to carry out the
same operations of remote control inherent in Model 1 and Model 3.
Describing now the external operations of Model 1, E.G.R.C. device for the
control of AM-FM radio reception. The AM-FM radio receiver is plugged into
a power outlet and set to ON. The volume control is set midway between
minimum and maximum. Bass control, treble control, and midrange control
are set to maximum. The function switch is set to FM stereo reception. The
tuner is set to 108MC which connects the E.G.R.C. device by radio waves,
thereby controlling any type of receiver tuned to the same frequency of
the E.G.R.C., the blank station of 108MC. The AM-FM radio receiver is now
ready to be controlled by remote control, via Model 1, E.G.R.C. device.
Describing now the internal operation of Model 1, E.G.R.C. device for the
control of AM-FM radio reception and tape recorder phonograph, microphone,
and electronic instrument functioning. See FIG. (1), a block diagram
drawing of the internal circuitry of Model 1, E.G.R.C. for the remote
control of AM-FM radio reception.
The transmitter (14) FM 108MC, connects the E.G.R.C. through the air waves
and enables the E.G.R.C. to transmit via (14) any transmitted signal-short
wave or long wave- from any transmitter, Four separate controls (13)
volume, bass, treble, and midrange enable the E.G.R.C. reception to be set
and controlled at a selected volume, bass, treble and midrange strength.
The audio amplifier (11) feeds into the volume, bass, treble and midrange
control (13) and enables a degree of amplification appropriate for
selected high or low intensity. The pilot stereo (15) 19KC, amplifies
stereo 19KC signal and transmits it again, thereby enabling stereo
reception. The demodulator (6) receives the intermediate frequency signal
from (5) and demodulates it. The output of demodulator (6) is separated
into two different signals consisting of a pilot frequency signal and an
actual sound signal. The actual sound signal passes through the audio
amplifier (11), whereby it is amplified even stronger. The amplified
actual signal passes through the volume, bass, treble and midrange
controls (13) and thenafter is retransmitted from transmitter (14), 108MC.
The second signal, the pilot frequency 19KC from demodulator (6) passes
onto the pilot stereo (15) 19KC amplifier, and thence to transmitter (14)
108MC. It is retransmitted from transmitter (14), which is tuned to the
same station, 108MC, the selected empty station. Monitor (12) may be
plugged in and set to ON, thereby enabling the input to the transmitter
(14) to be monitored.
The tape recorder, or phonograph, or microphone, or any other electronic
instrument is plugged into the auxilliary jack which automatically
disconnects the E.G.R.C. receiver system control circuitry and connects
the auxiliary jack input. In lieu of the receiver, the tape recorder, or
phonograph or microphone, or electronic instrument is activated and
implemented to be controlled remotely, via the E.G.R.C. device.
Describing now the Model 1, E.G.R.C. device remote control of operations
enabling the changing of the stations in the AM-FM radio receiver. See
FIG. (1) for clarification.
The AM-FM radio receiver is readied for reception in the same manner as
described in the internal operation of Model 1, E.G.R.C. Antenna (1) picks
up any and all signals transmitted into the airspace. The band selector
(8) selects the desired AM-FM band or short wave or long wave etc. The
selected band is adjusted by the tuner (9) which selects the desired
station. The amplified signal is mixed by the mixer (3) in conjunction
with the oscillator (7). The mixed output from the mixer (3) is fed to the
intermediate frequency amplifier (4) whereby it is amplified once and then
passes on to the intermediate frequency amplifier (5) whereby it is
amplified a second time. The amplified signal is then passed on to the
demodulator (6) which separates the radio wave carrier from the actual
sound. The audio amplifier (11) receives the actual sound and passes it on
to the four controls, volume, bass, treble and midrange controls (13).
Thenafter, the actual sound is retransmitted by the transmitter (14) FM
108MC, and received by the AM-FM radio receiver. The monitor (12) may be
plugged in and set to ON thereby enabling the input to the transmitter
(14) FM 108MC to be monitored. Thus it can be seen, the E.G.R.C. device
contains all the necessary controls to control remotely AM-FM reception,
short wave and long wave reception. The E.G.R.C. device receives through
the air all and any transmitted signals, and is enabled to transmit any
and all signals received, to the selected empty station in the AM-FM radio
receiver, station 108MC, a blank empty station. Also, the E.G.R.C.
transmitter is enabled to transmit to any receiver and is enabled to shift
from transmitting to one receiver to another receiver, regardless of the
receiver's design, company make or size. The E.G.R.C. is also enabled to
shift from one station to another, in the same receiver. For example:
Suppose a change is made in the AM radio receiver station, and the desired
station is now 80KC, the steps in the operation in changing the previous
station to changed station, 80KC, are as follows: The radio receiver is
readied for reception in the same manner as described in the internal
operation of Model 1, E.G.R.C. The band selector is tuned from FM to AM
80KC. The tuner is set to 80KC. Thereby the receiver is capable of
receiving whatever sound transmitted from station 80KC. In like manner,
FM, short wave, long wave etc. can be implemented in the changing from one
receiver to another. Also, in like manner a sound transmitted from a
television channel can be implemented on the empty radio station, empty of
sound. The E.G.R.C. transmitter may be changed to whatever frequency
desired and can transmit said frequency of station or channel to the empty
radio station. Any radio signal received and joined to transmitter (14) FM
108MC, can be transmitted and connected to any type of operational
receiver and thereby controlled remotely by the E.G.R.C. device without
the necessity of attaching, adapting or affixing anything to the exterior
or interior of the operational receiver.
Describing now the external operations of Model 1, E.G.R.C. device for the
remote control of television reception. See FIG. (2) a block diagram
drawing of a television unit remotely controlled by the E.G.R.C., for
clarification.
The television unit is plugged into a power outlet. Volume control is set
midway between minimum and maximum. Tuner is set to channel 12 a blank
empty station, empty of both sound and picture. The television set is now
enabled for television reception.
Describing now the internal operations of Model 1, E.G.R.C. device for the
remote control of television reception. See FIG. (2) a block diagram
drawing of the internal circuitry of Model 1, E.G.R.C. device for
clarification.
Transmitter (35) 204MC, carrier amplitude modulated is capable of
transmitting any signal received, sound, picture or color, onto channel
12, a selected empty station. Transmitter (35) 204MC, ties the television
reception means to the E.G.R.C. device through the air waves and transmits
received signals, whatever they may be, to the operational television set.
Transmitter (35) 204MC transmits the signals. Oscillator (23) 204MC
produces the carrier waves for transmitter (35) 204MC, which is
intercepted by modulator (34) and is modulated by modulator (34). The
modulated signals are fed into transmitter (35) 204MC, which transmits the
modulated signals through the air. The E.G.R.C. device is now enabled to
receive and transmit any signal, sound, picture and color, from any
television channel, from channel 2 through channel 83, the entire
television spectrum.
This is how the remote control operates. Antenna (16) receives all the
signals, sound, picture, and color from television channels 2 through 83.
Channel selector (22) selects the selected channel. The ratio frequency
amplifier (17) amplifies the signals selected from the selected channel.
The amplified signals pass into the mixer (18) which in conjunction with
the oscillator (23) mixes the signals and produces an intermediate
frequency signal. The intermediate frequency signal passes into the
intermediate frequency amplifier (19) whereby it is amplified. Then it
passes into intermediate frequency amplifier (20) where it is amplified a
second time. Thereafter the amplified intermediate frequency signal passes
through the demodulator (21) whereby the radio frequency carrier is
separated from the video-audio-color signal. The three different signals,
sound, picture and color, are amplified by their respective amplifiers.
The sound amplifier (27) receives the sound signal 4.5MC and amplifies it;
the picture amplifier (25) receives the picture signal 0-4MC and amplifies
it; the color amplifiers (26) and (28) receive the color signal 3.8MC
subcarrier and all other color signals and amplify them. The amplified
color signals pass on to control (30) a separate color control; the
amplified picture signals pass on to control (29) a separate picture
control; the amplified sound signals pass on to control (31) a separate
sound control. Control (29) controls picture intensity and contrast;
control (30) controls color shading and pigment; control (31) controls
sound volume. From controls (29) (30) (31) the signals pass into the mixer
(32), where all the signals, color, picture and sound are mixed together
to form a single signal. The single signal passes through modulator (34)
whereby it is amplitude modulated and fed into transmitter (35) 204MC,
which transmits it. Thus the picture, color, and sound are remotely
controlled by the E.G.R.C. device. The auxiliary jack is (24). Monitor
(33) may be plugged in and set to ON, thereby enabling the output from the
transmitter (35) to be monitored.
Model 2, E.G.R.C. device, "Mini" E.G.R.C. for remote control of AM-FM radio
reception is an application of the innovative method of remote control via
an E.G.R.C. device the size of a watch or a pen or a pendant or any other
similar tiny sized object. See FIG. (3) a block diagram drawing of an
AM-FM radio receiver remotely controlled by Model 2--"Mini" E.G.R.C. for
clarification. Describing now the internal operations of Model 2 E.G.R.C.
device. Antenna (37) receives any transmitted signal, short wave or long
wave, from any operating transmitter. Tuner (40) tunes radio frequency
amplifier (38) and oscillator (41) to select the desired station and sets
said station. Mixer (39) in conjunction with oscillator (41) mixes radio
frequency signal passed from radio frequency amplifier (38) to produce an
intermediate signal. The intermediate frequency signal 108MC, passes to
intermediate frequency amplifier (42). The 108MC is selected as the
intermediate frequency signal, as 108MC is a blank empty station, empty of
sound. Any other blank station and its related frequency would also serve
the same purpose and therefore could also be used. Intermediate frequency
amplifier (42) amplifies the intermediate frequency signal 108MC.
Thereafter, it is fed to antenna (43) 108MC output, which sends the
amplified signal into the air space of the surrounding area. Thence the
amplified signal enters the AM-FM receiver tuned to 108MC.
In Model 2, "Mini" E.G.R.C. device for remote control of AM-FM radio
reception, additional circuitry and electronic components can be added on,
within the tiny space of the watch, pen, or pendant to provide remote
control means and functions for television reception. See FIG. (4) a block
diagram drawing of Model 2 containing additional circuitry and electronic
components for remote control of television reception. This is how the
remote control of television reception by Model 2, "Mini" E.G.R.C. device
operates: Antenna (44) receives all the signals, sound, picture color,
from television channels 2 through 83, Channel selector (47) selects the
selected channel. The radio frequency amplifier (45) amplifies the signals
selected from the selected channel. The radio frequency amplifier (45)
amplifies the signals selected from the selected channel. The channel
selector (47) sets the radio frequency amplifier (45) and also oscillator
(48), to enable the two signals to be mixed by the mixer (46), in
conjunction with the oscillator (48) to produce an intermediate frequency
signal, of 204MC, which is the same frequency of channel 12, an empty
channel, empty of both sound and picture. The new intermediate frequency
signal, of 204MC, passes on to the intermediate frequency amplifier (49),
whereby it is amplified and acts as a transmitter for channel 12. Thus the
sound, picture and color are changed by the E.G.R.C. device.
This tiny E.G.R.C. may control an unlimited number of radios and television
units in a given area, depending upon the power output of the intermediate
frequency. Model 2, E.G.R.C. operates on the basis of mixing frequency
signals.
Now describing the external operation of Model 3, E.G.R.C. device on AM-FM
radio reception, utilizing a "Slave Driver" and a "Slave Receiver", the
AM-FM radio receiver, in the application of subcarrier waves for
electronic remote control. See FIGS. (5&6) a block drawing of a radio
receiver remotely controlled by Model 3, E.G.R.C. device, for
clarification.
The AM-FM receiver is plugged into an OFF-ON relay switch (80) which said
relay switch (80) is plugged into a wall outlet (79), and turns the
receiver ON. The power outlet (79) is remotely controlled by the "Slave
Driver" which in turn is remotely controlled by the Model 3, E.G.R.C.
device. The "Slave Driver" may be placed anywhere within a foot's distance
from the AM-FM receiver or may be placed on top of it. Volume control is
set midway between minimum and maximum. Bass control, treble control and
midrange controls are set to maximum. Band selector is set to FM. Tuner is
set to 108MC, which connects the E.G.R.C. device by radio waves, thereby
controlling the AM-FM radio receiver tuned to the same frequency of the
E.G.R.C. device, 108MC. Now that all the necessary preliminary adjustments
are made, no further adjustments are required for any of the AM-FM radio
components or for the "Slave Driver". All the following proceedings are
implemented by the manipulation of the E.G.R.C. device. The "Slave
Receiver", the AM-FM radio receiver, is mastered or rather driven by the
"Slave Driver".
Describing now the internal operation of Model 3, E.G.R.C. device for AM-FM
radio reception utilizing a "Slave Driver " and a "Slave Receiver", radio
receiver, in the application of subcarrier waves for electronic guided
remote control. See FIG. (5) a block diagram drawing of the circuitry of
Model 3, E.G.R.C. device utilizing a "Slave Driver" and a "Slave
Receiver", radio receiver, for clarification.
Antenna (50) which is a combined AM rod antenna and a FM stick antenna,
picks up any and all signals transmitted into the air waves and passes the
signal to radio frequency amplifier (51). Band selector (55) selects the
desired band, AM or FM or short wave or long wave etc. The selected band
is adjusted by the tuner (57) which selects the desired station. Radio
frequency amplifier (51) amplifies the desired signal. The desired radio
frequency signal is fed into mixer (52) which mixes the signal in
conjunction with the oscillator (56). The mixed output of either an
intermediate frequency of 10.7 for FM radio reception, 55.4 for AM radio
reception, is passed on to the intermediate frequency amplifier (53) where
it is amplified once. It is then passed on to intermediate frequency
amplifier (54) where it is amplified a a second time. It then passes on to
demodulator (58) where it is demodulated, thereby removing the actual
sound from the frequency carrier. The actual sound, AM, passes to audio
amplifier (59) where it is amplified even stronger. Thence the amplified
sound passes on to four controls (60) volume, bass, treble and midrange.
The output signal from the controls (60) is fed to modulator (62) thereby
in conjunction with oscillator (65) it is amplitude modulated to form
subcarrier 200KC. The modulator (62) output is fed to output amplifier
(63) which amplifies and powers the modulated signal from modulator (62)
thereby modulating the main transmitter (64) 150MC frequency modulated.
The main transmitter (64) 150MC frequency, is frequency modulated by the
actual sound. Output amplifier (63) which was fed to transmitter (64)
150MC frequency modulated, is now transmitted into the air space. In FM
stereo reception, in addition to the above components and related steps,
an amplifier (61) with its related steps are included, as follows:
Amplifier (61) a 19KC, amplifies the subcarrier's pilot, a 19KC frequency,
thereby enabling the Model 3, E.G.R.C. device, to transmit stereo
reception from any stereo station. The L-R signal, carried by the 38KC
subcarrier of FM stereo, is amplified by audio amplifier (59). Audio
amplifier (59) is so designated as to pass signals up to 45KC or more,
enables the L-R, 38KC, to pass with its regular sound. Following the
amplification of these two signals, 19KC and 38KC, the full beauty of
stereo reception is transmitted via a Model 3, E.G.R.C. device. The
auxilliary jack is (66) and the monitor is (67).
Describing now the utilization of a "Slave Driver" in the application of
the subcarrier waves for electronic guided remote control. See FIG. (6) a
block diagram drawing of the internal circuitry of a Model 3, E.G.R.C.
device, "Slave Driver", for clarification.
The primary function of a slave driver is to receive, demodulate modulate
and retransmit the actual sound matching to the frequency of the radio
receiver. This function is carried out as follows: Antenna (81) receives
the 150MC output sent through the air space, via the E.G.R.C. device.
Antenna (81) passes it on to radio frequency amplifier (68) which is tuned
to receive only 150MC frequency. The signal output from the radio
frequency amplifier (68) passes on to mixer (69) 150MC, which in
conjunction with oscillator (78) 139.3MC, mixes the signal, thereby
producing a new signal, intermediate frequency 10.7MC. Intermediate
frequency amplifier (70) 10.7MC, amplifies and strengthens this new
signal. The new signal passes on to intermediate frequency amplifier (71)
which amplifies it even stronger. The output signal from the intermediate
frequency amplifier (71) passes into demodulator (72) which demodulates
it, thereby separating the main carrier, the original 150MC, from the
subcarrier. Intermediate frequency amplifier (73) amplifies the 200KC a
subcarrier which is distinctly different from subcarriers used in close
proximity to one another, other E.G.R.C. devices, thereby preventing
interference in reception. The subcarrier 200KC passes on to intermediate
frequency amplifier (74) 200KC, which amplifies the subcarrier output even
more. The amplified subcarrier passes into demodulator (75), which
demodulates it, thereby separating the subcarrier from the actual sound.
Now the demodulator (75) passes out two signals, one is the DC of the
demodulated 200KC intermediate frequency amplifier. The demodulated DC is
utilized as a pilot to open or close the AM-FM radio receiver. Pilot DC
voltage is first amplified by DC amplifier (not shown) from thence it
passes on to the DC relay (80) which opens or closes. If power is present
in the 200KC demodulator, the relay turns to OFF, as there is an absence
of a power supply to operate it. As can be seen, the operation of 200KC
depends on the E.G.R.C. transmitter. When E.G.R.C. is turned to OFF, the
absence of the 200KC that follows automatically, turns OFF the AM-FM radio
receiver. When the E.G.R.C. is turned to ON, the presence of the
transmitted 200KC, automatically turns on the main receiver as described
above. The second signal that passes out from the demodulator (75) is the
complete sound in addition to the stereo transmission with all of its
associated signals. In AM reception the second signal is fed into the
audio amplifier (76) which amplifies sufficiently the audio signal to
drive the "Slave Driver's" transmitter (77). Transmitter (77) transmits
the complete amplified signal the output of audio amplifier (76) which
contains AM or Stereo FM, or sounds from a microphone or from adapted
equipment. The output from transmitter (77) is sent into the limited air
space, one foot or less from the transmitter (77) thereby preventing any
interference with other AM or FM receivers. The transmitted completed
amplified signal is received by the "Slave Receiver" which is tuned to the
same frequency as the "Slave Driver" 108MC. Auxilliary jack (not shown)
may be used as an antenna output from the "Slave Driver" to drive numerous
receivers by connecting a wire into the auxiliary jack, extending and
overlapping the wire over the receivers; the receivers come directly under
the remote control of the E.G.R.C. device.
Describing now the external operations of Model 3, E.G.R.C. device for
television reception utilizing a "Slave Driver" and a "Slave Receiver", a
television receiver, in the application of subcarrier waves for electronic
guided remote control. See FIGS. (7&8) for clarification.
The television cord is plugged into ON and OFF relay switch (119), which
said relay switch (119) is plugged into a wall outlet. If the television
receiver is battery driven, the relay switch (119) can be adapted to its
use as an ON and OFF switch. The volume control may be set midway between
minimum and maximum. The tuner may be set to channel 12, an empty blank
channel, empty of both sound and picture. The television unit is now ready
for reception. No further manipulation of dials or television components
are required. All sound reception and picture reception from the
television set can be activated, implemented, and deactivated now by means
of the Model 3, E.G.R.C. device in remote control operations.
Describing now the internal operations of Model 3, E.G.R.C. device for
television reception utilizing a "Slave Driver" and a "Slave Receiver", a
television receiver, in the application of the subcarrier waves for
electronic guided remote control. See FIG. (7), a block diagram drawing of
the internal circuitry of Model 3, E.G.R.C. for clarification.
Antenna (82) picks up all the transmitted television channels and feeds
them to radio frequency amplifier (83). The radio frequency amplifier (83)
amplifies the selected signal which was selected by tuner (87) and
oscillator (88), thereby selecting only one of the many stations and
rejecting all others. From radio frequency amplifier (83) the signal is
fed to mixer (84), which in conjunction with the oscillator (88) produces
a new intermediate frequency signal. The new signal is passed on to the
intermediate frequency amplifier (85) which amplifies it. The amplified
intermediate frequency signal is passed on to intermediate frequency
amplifier (86) which amplifies the signal a second time. The amplified
signal is then passed on to demodulator (89), where the audio and video
signals are passed through auxilliary jack (90). From (90) the signals are
passed to four different amplifiers (91), (92), (93) and (94). The 4.5 MC
sound carrier is amplified by sound amplifier (91). The picture carrier
0-4 MC is amplified by the picture amplifier (92). The 3.8 MC color
carrier is amplified by color amplifier (93). All associate color signals
are amplified by color signal amplifier (94). The signals, outputs from
(91), (92) and (93), are passed through volume controls- sound control
(95), picture control (96), and color control (97). Sound control (95)
enables any level of sound to be set; picture control (96) enables any
level of picture contrast to be set; color control (97) enables any level
of shading to be set. The outputs of (95), (96), (97) and (94) are fed
into mixer (98) where the signals-sound, color and picture, are mixed. The
mixed signals are passed on to amplitude modulator (101) which in
conjunction with subcarrier oscillator (100) modulates the signals to a
single 10MC subcarrier signal. The modulated signal is fed to the output
amplifier (102), whereby it is powered to modulate the 1000 MC FM
transmitter (103). The output from transmitter (103) is sent to antenna
(104) which passes it on to the air space of the surrounding area. Monitor
(99) may be plugged in and set to ON, thereby enabling the output of the
transmitter (103) to be monitored.
Now describing the internal operations of the "Slave Driver" and the "Slave
Receiver", the television receiver. See FIG. (8) a block diagram drawing
of the internal circuitry of the "Slave Driver" for clarification.
Antenna (105) picks up the 1000MC signal which is transmitted via the
E.G.R.C. transmitter (103). The signal is then passed on to the radio
frequency amplifier (106) which is pretuned to receive only the 1000 MC
signal. Thenafter it is fed to mixer (107), 1000 MC which in conjunction
with oscillator (109) 980 MC, mixes the signal to produce a 20 MC signal
for the intermediate frequency amplifier stages of the operation. The 20
MC signal is passed on to intermediate frequency amplifier (108) 20MC,
which amplifies it once, and thenafter fed to intermediate frequency
amplifier (110) 20MC which amplifies it a second time. The intermediate
frequency amplified signal is passed on to the demodulator (111) whereby
the main radio carrier is separated from the subcarrier. The 10 MC
subcarrier is fed to intermediate frequency amplifier (112) which
amplifies the subcarrier once and thenafter passes it on to intermediate
frequency amplifier (113), which amplifies it a second time. Then it is
passed on to demodulator (114) which removes the audio-video signal from
the subcarrier. The output from demodulator (114) consists of two signals.
One signal, the audio-video signal, is passed on to the amplitude
modulator (116) which in conjunction with oscillator (118) 204MC amplitude
modulates the signal. Thenafter, it is fed to transmitter (117) 204MC
which is the transmitter of channel 12. The signal is sent to antenna
(121) which transmits it to the surrounding area, not exceeding a foot's
distance from the location of the antenna (121), thereby preventing any
interference from other television units operating on the same frequency.
Auxilliary jack (not shown) may be used as an antenna output from the
"Slave Driver" to drive numerous television receivers, by connecting a
wire into the auxilliary jack and overlapping said wire over the
receivers. Without plugging the wire into the receivers, the receivers
would be directly under the remote control of the E.G.R.C. device. The
second signal of demodulator (114) output is a DC level signal, which is
utilized to turn the television receiver ON or OFF, by remote control. The
DC level of the output of demodulator (114) which originates from the
subcarrier 10 MC signal is amplified by DC amplifier (115) thereby
empowering relay switch to turn on the television receiver. When the
E.G.R.C. device is turned OFF the subcarrier signal 10 MC disappears,
thereby causing a loss in the DC level which automatically releases the
relay switch (119). Relay switch (119) is plugged into power source (147)
and (119) is connected to television receiver (148). When the relay switch
(119) is released the television is turned OFF.
Describing now the external operations of Model 4, E.G.R.C. device for the
adaptation of ultrasonic sound for remote control of AM-FM radio via the
E.G.R.C. device. See FIG. (9) a block diagram drawing of the AM-FM radio
receiver under the remote control of Model 4, E.G.R.C. device, for
clarification.
Antenna (122) picks up all the radio station signals and feeds them to
radio frequency amplifier (123). Radio frequency amplifier (123) amplifies
the selected station, selected by tuner (128) in conjunction with
oscillator (129). Mixer (124) mixes the signal, whereby a new intermediate
frequency signal is produced. Intermediate frequency amplifier (125)
amplifies the signal once and feeds it to the intermediate frequency
amplifier (126) where it is amplified a second time. The signal is passed
on to the demodulator (127) which separates the intermediate frequency
signal from the actual sound. The output of demodulator (128) passes on to
volume control (131), which sets the volume level and controls the output
to volume controls, which said controls respectively adjust the bass,
treble and midrange. Thenafter the signal is fed to audio amplifier (132)
which amplifies the actual sound. The amplified actual sound is fed to the
ultrasonic transmitter (134) 25KC which transmits through the air-space in
the form of ultrasonic waves 25KC. Monitor (133) may be plugged in and set
to ON, thereby enabling the output from the transmitter (134) 25KC to be
monitored. As the ultrasonic sound fills the air space it carries with it
remotely and wirelessly the complete actual sound to the surrounding air
space. Auxilliary jack is (130). See FIG. (10) a block diagram drawing of
an AM-FM radio receiver under the remote control of Model 4, E.G.R.C.
device, for clarification.
Microphone (135) picks up the ultrasonic waves 25KC and feeds them to
intermediate frequency amplifier (136) 25KC. The intermediate frequency
amplifier (136) 25KC, amplifies the ultrasonic waves and thenafter passes
them on to intermediate frequency amplifier (137) 25KC where they are
amplified a second time. Thence it is passed on to intermediate frequency
amplifier (138) where it is amplified even more, a third time. Demodulator
(139) separates the 25KC ultrasonic carrier from the actual sound, thereby
producing a DC signal for relay switch (143) which said relay switch (143)
is plugged into a wall outlet and turns the receiver ON. Audio amplifier
(140) amplifies the actual sound and thenafter feeds the amplified actual
sound to transmitter (141) 108MC FM, which transforms the actual sound
again to a radio wave. The radio wave is received by the AM-FM radio
receiver, tuned to the same frequency 108MC. The DC amplifier (142)
amplifies the DC output of pilot signal from the demodulator (139)
sufficiently enough to activate relay switch (143). The power supply is
(144). The radio receiver is (145).
Likewise, a Model 6, E.G.R.C. device may be constructed in such a manner
that it contains the features or functions to carry out the operations of
remote control inherent in Model 1, Model 3, Model 4 and Model 5 in a
single unit "Master Model" E.G.R.C. device.
It is understood that the form, implementation and adaptation of the
invention herewith described is to be taken as an illustrative embodiment
only of the same, and that various procedural changes may be resorted to
without departing from the spirit of the invention.
