Publication number: 20210371235Abstract: The present invention provides a contactless elevator control system and method. The system comprises an infrared touch sensor, a relay control device and an elevator button control device, wherein: the infrared touch sensor emits an array of multiple infrared beams, receives reflected infrared beams, calculates a vertical and lateral displacement, determines a corresponding coordinate information, calculates a corresponding elevator button, and sends a corresponding control; the relay control device drives the corresponding relay contacts to close. The solution uses the infrared touch sensor to achieve contactless control of elevator buttons, reducing the risk of spreading bacteria and viruses when touching the elevator buttons.Type: ApplicationFiled: February 11, 2021Publication date: December 2, 2021Applicant: Hong Kong Productivity CouncilInventors: Lawrence Chi-Kin POON, Edmond Chung-Man CHAN, Cheuk-Ming YIP

Patent number: 9125525Abstract: An apparatus for grinding a mineral includes a head operable to be attached to a bottle. The head includes a radial slider for controlling the coarseness of the grind. The apparatus further includes an inner grinding element, an outer grinding element, a shaft, and a neck sleeve. The inner grinding element is in communication with the head. The outer grinding element is also in communication with the head, wherein the outer grinding element and the inner grinding element are operable to rotate relative to each other. The shaft extends through the inner grinding element and the outer grinding element. The shaft couples with the inner grinding element and has a blunt end. The shaft also extends through the neck sleeve, which acts as a spacer between the inner grinding element and the blunt end.Type: GrantFiled: September 13, 2012Date of Patent: September 8, 2015Assignee: ACH Food Companies, Inc.Inventors: Allan E. Wade, Aaron F. Fitchko, Chung Man Chan, Alex Liu

Patent number: 7854550Abstract: A thermometer includes an illuminated display, which may act as an intelligent indicator of the change and level of temperature. The thermometer includes memory unit accommodating multiple users and their past records respectively. When a new temperature reading is obtained, the thermometer compares the new temperature against the immediate preceding record of the same user. The thermometer further includes a display module indicating the change of temperature reading and the fever status of the user.Type: GrantFiled: January 4, 2008Date of Patent: December 21, 2010Assignee: Aviton Care LimitedInventors: Chung Man Chan, Ching Ching Cheung, Ka Lun Fan, Hung Keung Tse

Publication number: 20090174548Abstract: A tracking system for monitoring a location of a person and initiating a communication or emitting an alarm if the tracking system is moved outside of a specified area. The tracking system may include a microprocessor module, a location determining module, a communication module and an alarm module. The location determining module determines the location of the tracking system. The communications module transmits and receives data relating to the location of the tracking system. The alarm module emits an alarm notification. The location determining module, the communications module and the alarm module are operably connected to the microprocessor module.Type: ApplicationFiled: January 5, 2009Publication date: July 9, 2009Applicant: Musical Electronics LimitedInventors: Chung Man Chan, Henry Ki Lun Wong, Ching Ching Cheung, Hung Keung Tse

Publication number: 20090177129Abstract: The present invention is a wrist massager particularly applying to the wrist part of human being adopting acupressure theory of Traditional Chinese Medicine (TCM) in order to circumvent wrist musculoskeletal disorders (MSDs). It comprises a wrist band operably engaged a control panel 4 and a motorised cushion housing 2 with protruding massage means3. The wrist band added with size-adjustable mechanism is designed for users to fit their wrist into the massager comfortably and firmly. It contains a motor/motors to produce vibration and deliver reciprocating and/or rotary massaging effect via the massage means3. Alternatively, the wrist massager is a plate 8 with planar bottom and a housing placed on the surface of the plate 8. A detachable massaging means protrudes from the surface of the said housing.Type: ApplicationFiled: January 4, 2008Publication date: July 9, 2009Applicant: AVITON CARE LIMITEDInventors: Chung Man Chan, Ken Chung Hang Leung, Lok Ting Wong, Ka Lun Fan, Ching Ching Cheung, Hung Keung Tse
