  • Patent number: 10268278
    Abstract: A hand gesture control system to be operated via hand gestures to receive a call from a mobile phone includes: a casing; a control unit installed inside the casing; a hand gesture recognition unit installed inside the casing, including an image capturing module and a hand gesture recognition module, wherein the image capturing module captures an image of a hand gesture of a user and transmits to the gesture recognition module for comparison, which feeds back an operation instruction to the control unit corresponding to the comparison; a wireless transmission unit communicates with the mobile phone via a wireless communication protocol for establishing communication between the mobile phone and the control unit; a microphone disposed at an exterior of the casing in order to receive a user's voice; and a loudspeaker disposed at an exterior of the casing in order to output the user's voice from the microphone.

  • Patent number: 10200676
    Abstract: The present invention discloses an image detection system of a vehicle for detecting at least one target object around a vehicle, and further detecting a distance between the at least one target object and the vehicle. The image detection system of the vehicle at least includes a light source unit, an image capturing unit and an alarm unit. The present invention primarily employs a laser beam incident onto the target object to form at least one optical pattern, and variation of the optical pattern and a motion object detection are collocated to effectively calculate the distance between the target object and the vehicle, thereby achieving an advantage of alarming and alerting a driver to safety of driving.

  • Patent number: 10194079
    Abstract: A vehicle surveillance system is disclosed and includes a plurality of image capturing units, an image processing unit, and a display unit for monitoring a position of at least one target around a vehicle and measuring a distance between the at least one target and the vehicle. The vehicle surveillance system utilizes a space domain determination module, a time domain determination module, and a ground surface elimination module to transform original images of the target around the vehicle into the bird's-eye-view panorama, and further detects variation of an optical pattern incident onto the target through a light beam emitted by a light source so as to effectively remind a driver on the on-going vehicle of the position of the target and the distance, and real-time detect and capture an image of any person approaching the vehicle, thereby achieving driving safety and securing lives and personal properties.

  • Publication number: 20060284832
    Abstract: Disclosed is a system for locating a laser spot on a screen. The system includes a projector, a laser pointer, a camera, a diffractive optical element, and a computer. The projector casts an image on the screen. The laser pointer casts the laser spot on the screen. The camera takes a picture corresponding to the image on the screen. The diffractive optical element is put between the screen and the camera in order to transform the laser spot into an easily observable diffractive pattern in the picture. The computer receives the picture from the camera and locates a semi-cursor on a display connected thereto based on the diffractive pattern in the picture.
