摘要： Methods and apparatuses pertaining to automotive parking assistance using radar sensors are described. A processor controls a plurality of radar sensors to transmit radio frequency (RF) signals and receive reflected signals reflected by an object such that each of the radar sensors individually transmits a respective RF signal and receive a respective reflected signal reflected by the object. The processor or the radar sensor detects one or more aspects of the object based on the respective reflected signals received by the plurality of radar sensors.

摘要： Various examples pertaining to a sensor system interconnect for automatic configuration of sensors of the sensor system are described. A sensor senses at least one parameter. The sensor also determines its respective position among a series of sensors. Based on a result of the determining, the sensor performing either a first procedure, responsive to the sensor being a first sensor in the series of sensors, or a second procedure, responsive to the sensor not being the first sensor in the series of sensors. The first procedure involves the sensor transmitting first data of the sensed at least one parameter via a second input/output (I/O) pin of the sensor. The second procedure involves the sensor receiving second data from a preceding sensor in the series of sensors via a first I/O pin of the sensor and transmitting the first data and the second data via the second I/O pin.

摘要： Various examples pertaining to a sensor housing design for millimeter wave (mmWave) sensors are described. A sensor housing may include a radar sensor, a printed circuit board (PCB), a radome and a PCB holder. The radar sensor may be capable of emitting a radio wave. The PCB may have a first side and a second side opposite the first side with the radar sensor mounted on the first side thereof to form a PCB assembly (PCBA). The radome may include a cavity in which the PCBA is disposed. The PCB holder may be disposed along a circumference of an inner wall of the radome, and the PCB holder may be configured to hold the PCBA such that a distance between an inner surface of the radome and a side of the radar sensor facing the inner surface of the radome is proportional to half wavelength of the radio wave.
