A magazine is provided for storing an information tape. The tape is wound on two spaced-apart spools and is a plastic film which has elastic recovery to provide a spring-like action on the spools. The spools are driven in a positive manner by a series of gears which connect one spool to the other spool. Long lengths of tape can be wound on the spools and freely rotated from one end to another without bunching, sagging or jamming. A pin extends outwardly from one of the gears parallel to the spoo...

An information retrieval system which comprises an optical system for scanning a film stored with informations by means of holography using a laser beam modulated according to the respective symbols constituting a series of symbols in inquiry information and generating a bright or dark signal according to whether or not a symbol selected from the above-mentioned sequence coincides with a symbol included in any desired information; photoelectric conversion elements for converting said signal into...

A medical identification, information and emergency medication packet adapted for wearing or carrying by a patient, said packet comprising an envelop--preferably transparent; a foldable information card slidably insertable in said envelope; and a frame comprehended within the card when so folded; said frame with the inside of the folded card defining at least one space within which is housed a dosage quantity of a medication to be administered to the patient in an emergency in accordance with in...

A color encoding format is disclosed wherein a chrominance signal in the form of a modulated subcarrier is buried in the midband of a wider band luminance signal. Comb filtering of the luminance signal midband prepares "troughs" in the luminance signal frequency spectrum. The chrominance signal is complementarily comb filtered to confine it to components falling in the vacated troughs of the luminance signal frequency spectrum. An illustrative use of this encoding format is in video disc recordi...

A picture information retrieval system in which each time an initial position detecting mark provided in correspondence with the first picture on an information recording medium for detecting the first picture passes the initial position during the retrieval operation the content of the counting section is corrected.

The optical transitions of extrinsically optically active soluble and insoluble materials become circularly dichroic when in contact with the twisted nematic structure of nematic liquid crystalline materials. The circularly dichroic optical properties induced in the normally extrinsically optically active materials can be utilized for information transfer applications.

A computer automated information system is adapted for use by the public and is installed in public gathering places for readily dispensing information regarding, for example, travel accommodations and the like. The system includes display and print-out components associated with the computer and interfaced for dispensing selected information quickly, accurately and economically, and is modular and compact to minimize maintenance and maximize versatility.

An information input device includes first and second counting means serially connected so as to be cyclically driven, a matrix circuit having row lines connected to an output from the first counting means and column lines, and a timing count value selecting circuit consisting of a plurality of AND circuits the respective one gate of which is connected to the respective column line of the matrix circuit and the respective opposite gate of which is connected to an output from the second counting ...

An adaptive information processing system includes a module, called a Nestor module, having a plurality (N) of input terminals 1, 2 . . . , j . . . , N, adapted to receive N input signals s.sub.1, s.sub.2 . . . , s.sub.j . . . , S.sub.N, respectively, and a plurality (n) of output terminals 1, 2 . . . , i . . . , n, adapted to present n output responses r.sub.1, r.sub.2 . . . , r.sub.i . . . , r.sub.n, respectively. A plurality of junction elements, called mnemonders, couple various ones (or a m...

A system for transmitting information and accomplishing control including a transmitter and at least one receiver in which the transmitter produces an ultrasonic wave or an electrical signal and includes a circuit for modulating the ultrasonic wave or electrical signal as a function of a time interval indicative of the control signal. The modulation is varied as an exponential function so as to assure more accurate reception and decoding of the intelligence by the receiver.
