Patent number: 11506317Abstract: A mounting device facilitates connecting an Internet of Things (IoT) device, such as thermostatic radiator valve (TRV) and automatic temperature balanced actuator (ABA), to a hydronic heating/cooling system to control the temperature of a room by changing the flow of hot/cold water through radiator. The mounting devices includes a male section and a female section, which is attached to the IoT device. The mounting device may be installed in two stages. First, a male section is attached to a component of the hydronic heating/cooling system (for example, a valve or manifold) by threading the male section onto the component. Second, a female section, is positioned to male section and locked into place by rotating a rotary sleeve. The female section (with the IoT device) may be easily removed by rotating the rotary sleeve into an unlock position.Type: GrantFiled: September 5, 2019Date of Patent: November 22, 2022Assignee: Computime Ltd.Inventors: Dick Kwai Chan, Ben Ren Tan

Patent number: 11371721Abstract: 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.Type: GrantFiled: November 9, 2020Date of Patent: June 28, 2022Assignee: Computime Ltd.Inventors: Dick Kwai Chan, Hamza Yilmaz, Ben Ren Tan, Wai-Leung Ha

Second, a female section, is positioned to male section and locked into place by releasing a sliding sleeve. The female section (with the IoT device) may be easily removed by retracting the sliding sleeve.Type: GrantFiled: April 1, 2019Date of Patent: July 13, 2021Assignee: Computime Ltd.Inventors: Dick Kwai Chan, Ben Ren Tan

Patent number: 10697650Abstract: 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.Type: GrantFiled: April 7, 2017Date of Patent: June 30, 2020Assignee: Computime Ltd.Inventors: Philip John Smith, Wai-Leung Ha, Dean Richard Jepson, Chung-Ming Cheng, Kwok Wa Kenny Kam, Hao-Hui Huang, Dick Kwai Chan, Hong Bin Liao

Patent number: 10291065Abstract: A smart plug that is partitioned into a plurality of printed circuit boards (PCBs) in a three dimensional manner to reduce its size. Aspects consider the effect of the possible increased internal temperature as the size of the smart plug is reduced. For example, thick metal foils connect various components of a smart plug to reduce heat dissipation within the smart plug. Also, a metal foil may transfer heat from contact metal on a PCB to a side wall of a plastic housing of the smart plug. The smart plug may comprise a computing device that obtains information identifying the attached electrical device and accesses device data about the time duration during which the attached electrical device exhibits transient characteristics. The computing device then uses the accessed data to effectively control the attached electrical device.Type: GrantFiled: January 23, 2017Date of Patent: May 14, 2019Assignee: Computime, Ltd.Inventors: Dick Kwai Chan, Kam Wai Lam, JZ Zheng, Wai Yin Shum, Brenton James Judge, Hamza Yilmaz, Patrick Yeung, Wai Ming Wu

Patent number: 9959719Abstract: 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.Type: GrantFiled: September 7, 2017Date of Patent: May 1, 2018Assignee: Salus North America, Inc.Inventors: Samuel Hong-Yen Pai, Wai-Leung Ha, Shen Owyang, Dick Kwai Chan, Wai Yin Shum, Kwok Wa Kenny Kam, Guang Quan Feng
