  • Publication number: 20200284892
    Abstract: An ultra-wideband-based system and method for detecting properties associated with a movable object in an environment such as an indoor environment. The method includes transmitting ultra-wideband radar signals to an environment, using an ultra-wideband transmitter, and receiving signals reflected from the environment as a result of the transmission of the first ultra-wideband radar signals using an ultra-wideband receiver. The method also includes processing the reflected signals and determining properties associated with a movable object in an environment based on the processed reflected signals, using the processor.

  • Publication number: 20090177129
    Abstract: 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.
