摘要： A method of generating a signal in an optical transmitter comprising a directly modulated laser and an amplitude modulator for modulating the output of the laser. The method comprises the steps of applying a first modulation signal representing data to be transmitted to the current of the laser such that the output frequency of the laser is modulated, and applying a second modulation signal representing the data to be transmitted to the amplitude modulator such that the amplitude of the laser output is modulated.

摘要： An optical amplifier is adapted to cancel the Raman gain of an optical transmission path that degrades those optical signals occupying the low end of the bandwidth such that the power is transferred from the latter signals to the optical signals occupying the high end of the bandwidth. More specifically, the optical amplifier adjusts the gain that it applies to the optical signals so that it favors the signal components at the low end of the bandwidth.

摘要： A tire control system for a vehicle is provided includes an RFID tag mounted to the tire and having a unique tire serial number stored within tag memory accessible to an external reader; a pass-through portal operatively entered and exited by the vehicle; one or more tire-directed antenna positioned within the portal for operatively receiving one or more one data transmissions of the unique tire serial number from the tire-based RFID tag; and one or more tire-directed RFID reader coupled to the tire-directed antennas for operably reading and storing within a tire-based database the unique tire serial number data. A vehicle-based RFID tag is mounted to the vehicle having a unique vehicle serial number stored within tag memory and transmitted to an external reader as the vehicle moves through the portal. A data processing computer is coupled to receive the portal-read unique tire serial number and vehicle serial number and conducts of the portal-read unique tire serial number data and the unique vehicle serial number data against prestored reference tire serial number data and prestored reference vehicle serial number data, respectively.
