  • Patent number: 11371721
    Abstract: A thermostatic radiator valve (TRV) assembly or automatic temperature balanced actuator (ABA) assembly controls a manifold assembly through a push pin bearing mechanism. The push pin bearing mechanism comprises a push pin that moves in a linear direction responsive to rotational movement of a motor gear that is coupled through a helical gear. Rotational movement of the push pin is prevented by a ball bearing assembly. Movement of the push pin is transferred to a manifold pin, which in turn, controls the manifold assembly. Because the push pin moves in a linear rather than a rotational fashion, erosion of the mated manifold pin is substantially reduced with respect to transitional approaches.

  • Publication number: 20220083155
    Abstract: The present invention supports the control of a plurality of controlled devices. With three dimensional accelerometer components, detection of a user action on a remote controller and the orientation of the remote controller are viable through small electronic devices. Aspects of the invention are based on the three dimensional accelerometer components to provide a remote controller that can detect the user action. Based on the user action, the remote controller transmits a signal to the controlled device which conveys the corresponding command. A selected controlled device may be matched to the remote controller. The remote controller and controlled device may also support a learning mode, in which the controlled device sends a list of supported commands to the remote controller. The remote controller then matches an associated action with each command in the command list.

  • Patent number: 11170899
    Abstract: Apparatuses and methods detect a health condition of a user that may be assessed from a thermal sensor signal and/or radar sensor signal. One or more resultant biometric vectors may be generated from biometric vectors based on the thermal and radar signals, where the resultant biometric vectors contain resultant information about one or more biometric features for a user. Hazard information about the user is obtained from the one or more resultant biometric vectors, where the hazard information is indicative of a health event for the user. Consequently, an appropriate action on behalf of the user may be performed to ameliorate the health condition. The one or more resultant biometric vectors may include additional biometric features and/or a time sequence of the resultant biometric vectors to enhance hazard prediction. Moreover, the apparatuses and methods may support the user in different settings including a home, business, or vehicle.

  • Publication number: 20210144025
    Abstract: Building blocks for a smart device such as a thermostat include a user interface (UI) unit and a terminal (TML) unit. A UI unit may support one or more input data from a user and/or sensors and/or one or more control terminals. The UI unit may process each input datum or a combination of the input data, generate a control signal to one or more control terminals based on the processing, and send the control signal to one or more control terminals over a communication channel. A terminal unit, which may consist of one or more control terminals, transforms the received control signal into one or more controls to one or more associated environmental generators. One or more UI units may control one or more controlled apparatuses in conjunction with a mobile app to allow a unified user experience.

  • Patent number: 10697650
    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.

  • Patent number: 10578318
    Abstract: A heating system includes a single thermostat that controls multiple thermostatic radiator valve (TRV) controllers that control heat transfer to radiators in a room. Each TRV controller has the capability to automatically detect the open/closing point and maximum heating point and to register corresponding pin positions of the valve. Each TRV controller is subsequently instructed by the thermostat to adjust the valve in relation to a determined percentage of the registered pin positions, thus accounting for the varying characteristics among the valves in the system. The TRV controller detects the maximum heating point by checking the rate of temperature rising and the open/closing point by sensing the temperature turning point through a temperature sensor situated appropriately in relation to the associated radiator.

  • Patent number: 9959719
    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.
