摘要： An optical amplification apparatus has a first optical amplification unit and a second optical amplification unit connected in tandem with an optical attenuator between them. A temperature sensor is located in the vicinity of an optical fiber included in the second optical amplification unit. A reference voltage generation circuit controls an automatic gain control (AGC) circuit according to an output signal of the temperature sensor Alight signal detector detects maximum or minimum power from among the powers of the wavelength components output from the second optical amplification unit. The AGC adjusts the pumping power to set maximum/minimum to a predetermined value.

摘要： In a rendering device 10, ROM 4 stores a vehicle model. A rudder angle sensor 3 detects a rudder angle of the vehicle, and based thereon, CPU 6 calculates an estimated path for the vehicle. The CPU 6 receives captured images from cameras 21 to 2N. The CPU 6 generates a display image based on those captured images, the estimated path, and the vehicle model. This display image includes the vehicle model arranged on the estimated path, and displayed on a display device 8 placed in the vehicle. In this manner, the display image generated by the rendering device 10 is indicative and helpful for a driver of the vehicle to exactly figure out a parking space available for the vehicle.

摘要： An optical communications device is disclosed which is equipped with a transmission unit adapted to send binary-coded electrical pulse signals to another optical communications device in the form of optical pulse signals. The transmission unit includes a modulator for producing an electrical pulse signal of a narrow pulse width only at each of rising and falling edges in the binary-coded electrical pulse signals and an electro-optic converter for converting the electrical pulse signal of a narrow pulse width into an optical pulse signal of a narrow pulse signal. As an alternative, the transmission unit includes a modulator which produces an electrical pulse signal of a narrow pulse width for each bit in the binary-coded electrical pulse signals only when it is at a high level and an electro-optic converter which converts the electrical pulse signal of a narrow pulse width into an optical pulse signal of a narrow pulse width.
