The apparatus further includes a transmit portion for wirelessly transmitting signals detected by the speed sensor and the cadence sensor to the display portion. The transmit portion is provided with a shaft portion extending in one direction, which rotatably supports the cadence sensor and the speed sensor. A measurement body portion including the speed sensor, the cadence sensor and the transmit portion is...

Conventionally, a non-conductive period is provided in a region in the vicinity of zero of an AC power voltage via a voltage detection circuit 14 to turn off reliably. The FET 17 maintains the ON state within several switching cycles after the non-conductive interval to rapidly restore the magnetizing coil current, so that the magnetizing coil current rapidly increases. An object is to suppress beat noise in the electromagnetic device. Within a prescribed interval following the non-conductive in...

It is an object of the present invention to provide a recording apparatus and a reproducing apparatus which change a picture compression rate depending upon a picture quality of a source which a user desires to retain, thereby a tape storage space being secured. A video-data compression rate N used by a 1:N video-data compression encoder 3 and a 1:N video-data compression decoder 6 is changed depending upon a picture quality set by a device 5 for setting a picture quality that a user desires. A ...

Via a mobile communication network, a transmission apparatus receives position information representing a current position of a reception apparatus. Based on the received position information, the transmission apparatus generates notice data indicating that it is necessary to correct preprogrammed program information identifying a program which has been preprogrammed for viewing or preprogrammed for recording and being generated at the reception apparatus, and transmits the generated notice data...

A communication apparatus includes a registering part, a paper feeder, an information storing part, a selector, a recording part, and a recording controller. The registering part registers information of communication apparatuses to communicate with beforehand. The paper feeder includes a plurality of paper feed stages selectively feeding recording paper, at least one of the paper feed stages having recording paper different in color or material from the recording paper placed on the other paper...

A rotational positioning apparatus that comprises an apparatus for moving a head or disk and that positions the head relative to the disk, with this rotational positioning apparatus capable of both static positioning and dynamic positioning, also comprises a processor for generating one positioning command to be input to a movement apparatus from two positioning commands.

A receiving apparatus for receiving a spread spectrum signal having a plurality of demodulating units for demodulating the spread spectrum signal, a signal combining unit for combining output signals of the demodulating units, a time-out signal generating unit for periodically generating time-out signals, a time-out detection unit for detecting a pilot signal from the received spread spectrum signal by the time-out signals, and an assignment unit for assigning the pilot signal detected by the ti...

The testing apparatus tests a steering apparatus including a torque sensor which detects a steering torque, a steering actuator which applies a steering force to a steering mechanism, and a controller which controls the steering actuator based on an output of the torque sensor. The apparatus includes a test signal generating unit which generates a test signal of a sine sweep waveform simulating an output signal of the torque sensor, a driving signal generating unit which generates a driving sign...

A lens apparatus configured to be mountable on a camera body having an image sensor includes a first focus lens unit, a splitting optical unit disposed between the first focus lens unit and the image sensor, a second focus lens unit disposed between the splitting optical unit and the image sensor, the second focus lens unit being movable from an initial position along an optical axis to vary a focusing state, a focusing state detection unit configured to detect the focusing state using a light f...

An imaging apparatus including a lens drive portion and an imaging lens. The lens drive portion, in response to a current signal moves the imaging lens to a position corresponding to the current signal in the optical axis direction. The imaging apparatus also includes a movement control portion that provides a current signal to the lens driving portion. The current signal is gradually changed from a first current signal corresponding to a first position before movement of the imaging lens, to a ...
