  • Patent number: 10753956
    Abstract: A motion detecting device includes an accelerometer configured to generate gravitational acceleration readings associated respectively with consecutive time segments, an angular acceleration sensor and configured to generate angular acceleration readings, and a processor operable in one of a standby mode and an active mode. When operated in the standby mode, the processor activates the accelerometer, deactivates the angular acceleration sensor, and determines whether the user is in a substantial moving state. When determined that the user is in the substantial moving state, the processor switches to the active mode to activate both the accelerometer and said angular acceleration sensor, in order to determine the motion of the user.

  • Patent number: 10292546
    Abstract: A cartridge is adapted to be inserted removably into a drain hole of a urinal, and includes a cartridge body, a guide plate member, a detecting module and a filter unit. The cartridge body has an internal space having an opening. The guide plate member is disposed in the opening, and is perforated to guide liquid which exits the urinal via the drain hole to flow therethrough into the internal space. The detecting module includes a drug-detecting chip for detecting presence of a specified drug, and a controlling chip for controlling operation of the drug-detecting chip according to measured displacement of the guide plate member.

  • Patent number: 9573129
    Abstract: A sensing system includes a processing unit and sensor chip. The sensor chip includes a microelectrode array, a droplet space over the microelectrode array, and a plurality of control units coupled together in a daisy-chain configuration. Each of the control units is coupled to a respective one of the microelectrodes of the microelectrode array. The control units are controlled by the processing unit to drive movement of a droplet in the droplet space, and to inspect the droplet via the microelectrodes.

  • Patent number: 9506777
    Abstract: A micro-electromechanical apparatus having a signal attenuation-proof function, and a manufacturing method and a signal attenuation-proof method thereof are disclosed. The micro-electromechanical apparatus includes a substrate, an insulation layer, and a sensing unit. The substrate has a doped region in which a majority of conductive carriers have the same polarity as an electronic signal. The insulation layer is located on the substrate, and the sensing unit is located above the insulation layer and forms the electronic signal when sensing a force.

  • Patent number: 8736251
    Abstract: A digital sensing apparatus includes a sensing unit capable of providing a sensing response associated with an environmental parameter, and a digital readout module including a reading unit for generating a pulse signal having a pulse width associated with the sensing response, and a converting unit. The converting unit includes a clock signal generator for generating a variable-frequency clock signal, and a counter operable to count a width value of the pulse width of the pulse signal using the clock signal, so as to generate a digital sensing code. The frequency of the clock signal from the clock signal generator is adjustable to adjust resolution of the width value of the pulse width of the pulse signal.
