    摘要： The present application relates generally to conveyances and, more particularly, to wheelchairs. In one embodiment, a wheelchair includes a seat assembly coupled to a chassis. The chassis includes a frame having a rear wheel support member, one or more front wheel support members extending in a forward direction from the rear wheel support member, and a seat support member. The rear wheel support member comprises a central portion and left and right portions extending downward from the central portion. The wheelchair also includes one or more drive wheels for propulsion of the wheelchair, a set of front wheels for supporting the wheelchair, and a shrouding system for at least partially covering the frame and other components of the wheelchair.

    摘要： A system includes a radio frequency transceiver. A baseband processor includes an automatic gain control module. The automatic gain control module has a gain that changes from and subsequently returns to a predetermined value each time the radio frequency transceiver receives a radio frequency signal. The baseband processor is configured to selectively generate an interrupt signal each time a radio frequency signal is received based on a magnitude of the change in the gain of the automatic gain control module and a length of time in which the gain returns to the predetermined value. A control module is configured to identify a radio frequency signal received by the radio frequency transceiver as a radar signal in response to the baseband processor having generated a plurality of interrupt signals at substantially equal time intervals.
