摘要： A scanning beam projection system includes a scanning mirror having a fast-scan axis and a slow-scan axis. Movement on the slow-scan axis is controlled by a slow-scan scanning mirror control system. The control system receives position information describing angular displacement of the mirror. An outer loop of the control system operates in the frequency domain and determines harmonic drive coefficients for a scanning mirror drive signal. An inner loop of the control system operates in the time domain and compensates for a scanning mirror resonant vibration mode at a frequency within the frequency band occupied by the harmonic drive coefficients.

摘要： The temperature of a laser diode changes in response to video content across a line of a displayed image, and the radiance changes as a function of temperature. An adaptive model estimates the temperature of the laser diode based on prior drive current values. For each displayed pixel, diode drive current is determined from the estimated diode temperature and a desired radiance value. A feedback circuit periodically measures the actual temperature and updates the adaptive model.

摘要： A radio system having a hub transceiver and a plurality of customer premise transceivers at different distances from the hub transceiver. Each of the customer premise transceivers includes an antenna for transmitting an upstream radio signal to the hub transceiver and receiving a downstream radio signal from the hub transceiver. A selected exchangeable attenuator pad is mounted on the customer premise antenna in the path of the radiated signals for attenuating the upstream and downstream radio signals. The attenuator pad is selected in order to compensate for the different transmission path losses in order to provide a fixed predetermined signal strength in the downstream radio signals to each of the customer premise transceivers and a fixed predetermined signal strength to the hub transceiver from each of the customer premise transceivers.
