Abstract: A self-adjusting balance valve controller controls water flow through a hydronic emitter in a heating and/or cooling temperature control system. The valve controller obtains a measured temperature differential between an inlet and an outlet of the hydronic emitter and determines a displacement of a coupling pin from the measured temperature differential. The valve controller then instructs a driving mechanism to move, through a coupling mechanism, the coupling pin to adjust a valve that results in a desired water flow through the hydronic emitter. The valve controller may maintain a stable temperature differential at a desired differential value, which may be obtained through a user interface or from a memory device. Moreover, the desired differential value may vary with different times of operation or temperature control situations.

Abstract: A system utilizes the colocation of the sensing and the control or other powered sections of the product to supplement the environmental conditions in which the energy harvesting sensors operate, thus providing a robust energy source for sensors to operate.

Abstract: An entry sensor, which supports either wireless or wired operation, facilitates installation and is adjustable for gaps between a building entry barrier such as a door or window and the surrounding frame. The sensor, which may be implemented as a single piece design, includes an adjustment mechanism that enables an installer to vary the extension of the sensor to match the actual gap so that the sensor properly secures the building entry when closed. The sensor includes a detector that determines the state of a switch that is responsive to the movement of a plunger mechanism, where the state is indicative whether the building entry barrier is opened or closed, and that may determine whether the sensor is tampered with. The sensor also may facilitate battery replacement that protects the associated circuitry during the replacement.

Abstract: A technique provides apparatuses, methods, and computer readable media for sending sleep information from an end device to a central unit of a network, in which the wake-up time of the end device is aligned to the scanning time for the central unit. The technique addresses at least two considerations: the clock accuracy of the end device is accounted for, and the reason that the end device requests sleep mode operation is provided. To address the above considerations, the end device may send its clock tolerance information and/or request for sleep mode (RSM) command to the central unit once the end device is connected via the network. The central unit may then adjust the scanning time based on the clock tolerance information. If the central unit receives a response from the end device during the adjusted scanning time, the central unit deems that the end device is still connected.
