Abstract: A system described herein may determine transformations, differences, variations, etc. in radio frequency (“RF”) waveforms sent by a device in order to detect motion-based events. Models associated with the differences in such RF waveforms may be used to identify particular types of events, such as the presence of an individual in a room or other area, a type of motion, or other types of events. An interval or rate at which the device outputs RF waveforms may be modified, in order to increase the resolution of the determination of differences between the RF waveforms as sent and the RF waveforms as received, and/or to conserve power.

Abstract: An architecture and method for communicating between multiple processors. In one embodiment, first data is transferred from a first processor into a first memory. In the present embodiment, multiplexing circuitry connects the first processor to the first and second memories, but the first processor only has access to the first memory. Similarly, second data is transferred from the second processor into the second memory. Multiplexing circuitry connects the second processor to the first and second memories, but the second processor only has access to the second memory. In the present embodiment, the multiplexing circuitry switches the connection between the first processor and the first and second memories and the second processor and the first and second memories. In so doing, the first processor is switched from having access only to the first memory to having access only to the second memory.
