IPC: H04B10/516
Filed: 1990-09-07
Abstract: PURPOSE:To change an action point so that a difference of the compared result may be minimum and to always set the action point at an optimum value by controlling the action point of an optical modulator in accordance with the compared result between a 1st signal in proportion to the average power of the output from an optic- electric conversion means and a 2nd signal in proportion to the mark rate of an input signal. CONSTITUTION:This device is provided with an optical branching means 21 which fetches a part of output signal light to a bias control means, the opto-electric transducer means 15 which transduces the output signal light to an electric signal, an average power output means 16 which inputs the output from the means 15 and outputs the 1st signal 4 in proportion to the average power of the electric signal, a mark rate detection means which outputs the 2nd signal 5 in proportion to the mark rate of the input signal 3, and control signal generating means 11-13 which compare the 1st and the 2nd signals 4 and 5 and output a control signal for controlling the action point of the optical modulator 10 in accordance with the compared result. Thus, the action point is set at the optimum value in order to compensate the deterioration of the characteristic of main signal light caused by the change of the characteristic of the modulator without giving waveform distortion to the main signal light.

IPC: G01S13/75
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To supply sufficient power for the transmission from a responder to an interrogator even when the responder and the interrogator are located comparatively away from each other. SOLUTION: An interrogator 10 gives a carrier with 1st or 2nd frequency different from each other depending on transmission data selectively to an antenna coil 17. A tuning frequency of a tuning circuit consisting of a transmission reception coil 31 and a tuning capacitor 32 of a responder 30 is selected to be a 3rd frequency that is an intermediate frequency between the 1st frequency and the 2nd frequency. The interrogator 10 sends a carrier with a frequency nearly equal to the 3rd frequency for a prescribed period after data transmission to the responder 30. In the case that the responder 30 conducts a prescribed requiring high power consumption, since the carrier with a frequency nearly equal to the tuning frequency is sent, the degree of coupling is enhanced and the responder 30 produces much more power.
