  • Patent number: 11944412
    Abstract: A blood pressure detection device manufactured by a semiconductor process includes a substrate, a microelectromechanical element, a gas-pressure-sensing element, a driving-chip element, an encapsulation layer and a valve layer. The substrate includes inlet apertures. The microelectromechanical element and the gas-pressure-sensing element are stacked and integrally formed on the substrate. The encapsulation layer is encapsulated and positioned on the substrate. A flowing-channel space is formed above the microelectromechanical element and the gas-pressure-sensing element. The encapsulation layer includes an outlet aperture in communication with an airbag. The driving-chip element controls the microelectromechanical element, the gas-pressure-sensing element and valve units to transport gas.

  • Patent number: 11944935
    Abstract: A gas detection purification device is disclosed and includes a main body, a purification unit, a gas guider, a gas detection module and a controlling-driving module. The main body includes an inlet, an outlet, an external socket and a gas-flow channel disposed between the inlet and the outlet. The purification unit is disposed in the gas-flow channel for filtering gas introduced through the gas-flow channel. The gas guider is disposed in the gas channel and located at a side of the purification unit. The gas is inhaled through the inlet, flows through the purification unit and is discharged out through the outlet. The gas detection module is plugged into or detached from the external socket. The controlling driving module is disposed within the main body and electrically connected to the gas guider to control the operation of the gas guider in an enabled state and a disabled state.

  • Patent number: 11937903
    Abstract: A blood pressure device includes a first blood pressure measuring device, a second blood pressure measuring device, and a controller. The first blood pressure measuring device is to be worn on a first position of a wrist so as to obtain a first blood pressure information of the first position. The second blood pressure measuring device is to be worn on a second position of the wrist so as to obtain a second blood pressure information of the second position. The controller is electrically coupled to the first blood pressure measuring device and the second blood pressure measuring device so as to adjust tightness between the expanders and the user's skin, respectively. The controller receives, processes, and calculates a pulse transit time between the first blood pressure information and the second blood pressure information, and the controller obtains at least one blood pressure value based on the pulse transit time.

  • Patent number: 11928542
    Abstract: A system for detecting the direction of movement of an RFID tag along a path comprising two RFID portals, each of said portals being arranged to detect an RFID tag in a respective zone along the path, the zones being arranged to be effectively exclusive of one another, a RFID tag reader having an associated processor and multiple separate ports, each port being connected to one or the other of the portals, the processor being arranged to determine which portal first receives a RFID tag signal or signals and which portal subsequently receives a second signal from the same tag or tags detected by the first signal receiving portal, the processor providing a signal corresponding to a direction of movement, along the path from the first signal receiving portal to the second signal receiving portal.
