Abstract: 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.

Abstract: A system that implements wireless communication with replay protection for lower power building control applications. In one example, a battery-powered device includes a counter value with each message transmitted to an always-on device. If the always-on device receive an invalid counter value, instead of sending back an acknowledgement, it sends back a message containing an updated counter value. The battery-powered device may keep its receiver on after sending a message for at least a period of time, the battery-powered device receives the message and updates its counter with the received updated counter value. Since it did not receive an acknowledgement, it retries its original message, this time with the updated counter value. The retry message is likely to be successfully transmitted.

Abstract: A building automation system may adjust operation of a building system based upon information regarding the relative location of one or more users of the building automation system. In some embodiments, a mobile device having location services for determining a location of the mobile device may provide this information. A mobile device may include a user interface, a memory for storing two or more predetermined geo-fences each defining a different sized region about a home of a user of the mobile device and a controller operatively coupled to user interface and the memory, the controller configured to accept a selection of one of the two or more predetermined geo-fences via the user interface. The controller may report when the location of the mobile device crosses the selected one of the two or more predetermined geo-fences to a remote device. Other geofencing approaches are also described.

Abstract: 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.

Abstract: An auto changeover mechanism for a thermostat. A heat and cool mode auto changeover with single or crossed setpoints may be an approach for doing a single setpoint auto changeover, an approach that can handle auto changeover with separate heat and cool setpoints that do not require the cool setpoint to always be higher than the heat setpoint, and also an approach that does not necessarily require a dead band between the setpoints. A hysteresis may be associated with switching to the other mode. The thermostat having the auto changeover mechanism may have a display of a mode that automatically changes between heat and cool.

Abstract: Many different factors may affect a user's perceived thermal comfort level within a building. Controlling a room temperature according to what the temperature may feel like to a user (i.e. the “feels-like” temperature) may increase a user's comfort level in the building. An HVAC controller may be programmed to determine a temperature offset based on one or more environmental conditions in and/or around the building, and to apply the temperature offset to the indoor temperature, resulting in a feels-like temperature. The HVAC controller may be further programmed to control an HVAC system in accordance with the feels-like temperature.

Abstract: A fall-arrest anchor comprising a single, elongated member having a breaking strength more than 5,000 lb (22.5 kN). The single, elongated member comprises a first anchor portion sized and configured for attachment to a building and a second worker-attachment portion sized and configured for attachment to a worker's lifeline. The first anchor portion is at least about twice as long as the second worker-attachment portion, and the first anchor portion and the second worker-attachment portion are joined at an angle such that subjecting the fall-arrest anchor to a fall-arrest stress load visibly deforms the fall-arrest anchor and visibly changes the angle.

Abstract: Full body safety harnesses for fall arrest comprising a substantially rigid, resilient and water-resistant core throughout substantially the entire body harness frame.
