Title: High-voltage solid-state switch
IPC: H04Q3/52
Filed: 1980-12-12
Abstract: Hartman-16 HIGH VOLTAGE SOLID-STATE SWITCH A high voltage solid-state switch utilizes a dielectrically isolated lightly doped n type semiconductor body with a heavily doped p type anode region, a heavily doped n type first gate region, a moderately doped p type second gate region, and a heavily doped n type cathode region. The second gate region surrounds the cathode region. The first gate region is located directly between the anode region and the second gate region. The doping levels of the regions and the location of the first gate region between the anode and cathode regions facilitates a current break feature of the switch.

Granted: 2018-10-15
Abstract: A method of operating an automotive radar system (10) for avoiding interference by other radar systems is provided. The automotive radar system (10) includes a radar transmitter unit (12) for transmitting radar waveforms (xTx, xTx) towards a scene, a radar receiving unit (16) for receiving radar waveforms (xRx, xRx] that have been reflected by a target (26, 28) in the scene, and an evaluation and control unit (20) for decoding range-Doppler information from the received radar waveforms (xRx, xRx). The method comprises steps of transmitting (32) a first sequence of radar waveforms (xTx) and a second sequence of radar waveforms (xTxk) towards the scene that differs from the first transmitted sequence of radar waveforms (xTx) by predetermined phase shifts (cpk). First range-Doppler information and second range- Doppler information are decoded (36). Deviations of the second range-Doppler information from the first range-Doppler information are compared (44) to at least one predetermined deviation value. Based on the results of the comparing, a potential interference condition is identified (46)
