摘要： A fall detection system includes a radar that generates emitting radio waves and receives reflected radio waves from a person under detection, a data generator that generates a point cloud according to the reflected radio waves, an area determining device that determines a sub-area of a detecting area in which the person under detection lies, and a classifier that determines whether the person under detection falls according to the point cloud. The classifier adaptively processes the point cloud with different methods according to sub-areas as determined by the area determining device respectively to determine whether the person under detection falls.

摘要： An augmented-reality system includes an image capture device that obtains a captured image, an image processing unit that receives and processes the captured image to determine space configuration of a scene; a user interface that receives a position of a fiducial point inputted by a user; and a rendering device that superimposes a fiducial mark at the position of the fiducial point on the captured image. The rendering device superimposes a first computer-generated image representing a sensor at an install height above the fiducial point and on a wall of the captured image.

摘要： A wireless security device includes a nonconductive housing, a mother circuit board, a wireless expansion card, and a metal reflector. The mother circuit board and the wireless expansion card are disposed in the nonconductive housing. The mother circuit board includes a processor. The wireless expansion card includes a dielectric substrate, a ground plane, an inverted-F antenna, and an RF (radio frequency) module. The metal reflector is positioned between the mother circuit board and the wireless expansion card, and is close to the inverted-F antenna. The metal reflector is configured to reduce EMI (Electromagnetic Interference) from the mother circuit board so as to maintain performance of the inverted-F antenna.
