  • Patent number: 7826122
    Abstract: An optical modulation apparatus that performs optimum bias voltage control for optical modulation without using a pilot tone. A drive unit generates a drive signal by adding a bias voltage to an input data signal. A light modulation unit modulates input light output from a light source unit, in accordance with the drive signal, and outputs the results as optical signals. A forward monitoring unit monitors a forward signal of the light modulation unit and outputs the forward signal. A reverse monitoring unit monitors a reverse signal of the light modulation unit and outputs a reverse signal. A bias control unit controls the bias voltage so that a measured monitor ratio matches a target value of the ratio between the forward signal and the reverse signal, obtained when the operating point of the light modulation unit is in a predetermined position on its operation characteristic curve.

  • Publication number: 20090324256
    Abstract: In an optical transmitter, a laser emits light. A laser driving controller controls driving of the laser by superimposing modulation signals on laser driving signals to generate laser driving superimposed signals and by applying the laser driving superimposed signals to the laser to cause wavelength fluctuations in laser output light to suppress nonlinear optical phenomena during optical fiber transmission. An optical power variable controller variably controls a power of the laser output light. An optical fluctuation compensator suppresses optical fluctuations by monitoring output light from the variable controller to detect optical fluctuations accompanying wavelength fluctuations from monitoring results and by controlling a gain of the variable controller.

  • Patent number: 7337867
    Abstract: A vehicle-pedal backward-displacement preventing device. A pedal bracket has side plates each including a front end at which the pedal bracket is attached to the dash pane. A bulge protrudes in a protruding direction away from the other of the side plates. An operating pedal having a depressible portion is provided by its lower end portion. A guide member is associated with an upper end portion of the pedal bracket and a vehicle body member. The guide member causes the upper end portion of the pedal bracket to be downwardly displaced, upon displacement of the pedal bracket, whereby the pedal bracket is deformed with the side plates being made to buckle, so as to restrain the displacement of the depressible portion of the operating pedal toward a driver's seat. Each side plate has an aperture located in its region which includes a crest portion of the bulge, such that a strength of each side plate against a load is reduced most in the crest portion.

  • Patent number: 6487686
    Abstract: An error correction method and a transmission apparatus used in a transmission using a frame including a header and a payload are provided. In the error correction method and the transmission apparatus, a pseudo error is inserted in check bits of the frame to be transmitted. Thus, an error-correcting function of a transmitter and a receiver can be easily tested. A mismatch of a state of validation or invalidation of the error-correcting function between the transmitter and the receiver can be avoided without affecting a main signal by inserting information on whether or not an error correction is performed in an unused area of the header in the transmitter.
