摘要： The occupancy status of a building space may be determined by sensing an indication of motion in the building space, in response to sensing the indication of motion in the building space, starting an occupied time period having a length during which the building space is indicated as being occupied, determining a measure related to a number of subsequent sensed indications of motion in the building space during the occupied time period, and selectively adjusting the length of the occupied time period based on the measure related to the number of subsequent sensed indications of motion in the building space during the occupied time period.

摘要： A building automation system includes a host device and a plurality of client devices that can communicate with the host device via a frequency hopping protocol. The host device is configured to create and/or store a frequency hopping sequence including a plurality of ordered predetermined frequencies, and listens for communications from the plurality of client devices. Each cycle through the frequency hopping sequence is considered to be a channel. The host device may define a plurality of channels, with some of the plurality of channels reserved for routine messaging between the host device and the plurality of client devices and some of the plurality of channels reserved at times for higher bandwidth data communications.
