  • Patent number: 11890564
    Abstract: A perception and planning system includes a system frame and one or more cooling fans mounted on a first side of the system frame to generate an airflow flowing outwardly to remove at least a portion of the heat generated by the processors. The system further includes an air filtering module mounted on a second side of the system frame to filter the air flow flowing inwardly to remove durst or contaminated material from the airflow. The air filtering module includes an air filter, a mounting plate, and a cover plate. The mounting plate can be mounted on the second side of the system frame to receive the air filter. The mounting plate includes one or more magnets. The cover plate can be attached to the mounting plate by a magnetic force generated from the magnets to keep the air filter between the mounting plate and the cover plate.

  • Patent number: 11835618
    Abstract: A multiple-target vital sign detector includes a self-injection-locked oscillator (SILO), a chirp up/down converter, a frequency demodulator and a multiple-target vital sign processor. The chirp up/down converter performs conversion from an oscillation signal generated by the SILO to a frequency-modulated continuous wave (FMCW) signal to detect an area and from a received FMCW signal reflected from the area to an injection signal, while the SILO is injected with the injection signal to enter a self-injection-locked state. The locations and vital signs of multiple subjects are extracted from the oscillation signal using the frequency demodulator and the multiple-target vital sign processor. The objective of using the SILO is to improve the sensitivity of the FMCW detection process so as to more effectively distinguish the vital signs of multiple subjects at different locations.

  • Patent number: 11747458
    Abstract: A FCFMSIL radar includes a SILO, a frequency conversion unit, an antenna unit, a demodulation unit and a processing unit. The frequency conversion unit converts an oscillation signal of the SILO into a FMCW signal. The antenna unit transmits the FMCW signal to an area as a transmitted signal and receives a reflected signal from the area as a received signal. The frequency conversion unit converts the received signal into an injection signal and injects it into the SILO. The demodulation unit demodulates the oscillation signal into an in-phase demodulated signal and a quadrature demodulated signal. The processing unit processes the in-phase and the quadrature demodulated signals to obtain a baseband signal and thus acquire a phase and a frequency of a tone in the frequency-domain baseband signal, and determines the tone corresponding to one or multiple objects based on the phase and frequency of the tone.
