  • Patent number: 9744756
    Abstract: A method, an apparatus and a computer readable medium for producing a prototype diagram of a three dimensional (3D) object are provided. In the method, an object in a 3D diagram is scanned to determine transections and intersections at which each of the transections overlaps with the object are determined in order. Then, whether each of the intersections is supported on a neighbor transection of the transection is determined. If the intersection is not supported on the neighbor transection, a support frame is disposed on the location of the intersection between the transection and the neighbor transection. At last, all the transections are combined to produce a prototype diagram of the object.

  • Patent number: 9424769
    Abstract: A display and a brightness adjusting method thereof are provided. In the method, an object located in front of a touch screen of the display is detected and a distance between the object and the touch screen is estimated and determined whether to be less than a first preset value. When the distance is less than the first preset value, the brightness of the touch screen is adjusted according to a light adjusting ratio in a brightness distribution curve. Then, time is accumulated after the brightness adjustment and when the accumulated time is over a second preset value, the brightness of the touch screen is resumed to original brightness.

  • Patent number: 9400932
    Abstract: An identification method and an apparatus utilizing the method are disclosed. The disclosed method comprises capturing a first examining image at a first direction, performing a face detection process on the first examining image to identify a first face image in the first examining image, detecting a number of straight lines which are within a detecting image block of the first examining image but outside the first face image, comparing the number of straight lines with a quantity threshold to obtain a first judgment value, and judging if the first face image pass an examination at least according to the first judgment value.

  • Patent number: 9326148
    Abstract: A display apparatus and an authorizing method thereof are provided. The display apparatus includes a display panel and at least one wireless communication module disposed behind the display panel. In the method, a frame is displayed on the display panel, and the at least one wireless communication module is used to communicate with the wireless communication apparatus so as to obtain authorization data. Each of the at least one wireless communication module is operated at a working frequency capable of penetrating through the display panel to communicate with the wireless communication apparatus. An authorization process related to a content of the frame is executed by using the received authorization data.
