  • Patent number: 12646351
    Abstract: There is provided a human falling detection system including an image sensor, a thermal sensor and a microphone. The image sensor captures an image frame that is used to identify a face and a height-width ratio of a human image. The thermal sensor is used as a filter for filtering out a living body and captures a thermal image that is used to identify a height-width ratio of a human thermal image. The microphone records a time stamp of an abrupt sound appearing.

  • Patent number: 12590833
    Abstract: A proximity sensing device includes: a light source, a sensing unit, a light guide unit, and a window. The light source emits light, which is guided by the light guide unit to the window. The emitted light reflected by an object is received by the same window. The light guide unit includes a partial-transmissive-partial-reflective (PTPR) optical element, whereby the light emitted from the light source is reflected by the PTPR optical element, while the light reflected by the object passes through the PTPR optical element. There is only one window required.
