Patent number: 7131764Abstract: A backlight apparatus includes a guiding element and a light source disposed at one side of the guiding element. There is a plurality of reflective patterns at the bottom surface of the guiding element. Each reflective pattern is composed of at least one concavity and at least one convexity. The concavity is disposed at the rim around the convexity. As the light source emits light to the guiding element, the reflective area is increased by the concavity of the reflective pattern for increasing the reflecting effect and for distributing the brightness more uniformly, and thereby higher brightness and uniformity can be achieved.Type: GrantFiled: June 1, 2005Date of Patent: November 7, 2006Assignee: Nano Precision CorporationInventors: Chien-Hung Hsu, Wen-Yung Huang, Ming-Dah Liu, Bor-Jyh Pan

Patent number: 6646675Abstract: A security monitoring system with addressable capability is provided. This system allows a plurality of video cameras to be connected to the security guard room via a single cable instead of a plurality of dedicated cables, as in the prior art. The security monitoring system comprises the following: a cable; a central control unit connected at the first end of the cable, capable of issuing a first signal; at least one addressable video camera connected at the second end of the cable connected to the central control unit; and a monitoring device for displaying a second signal. The addressable video camera receives the first signal from the central control unit and compares the first signal with a preset value; if these match, the addressable video camera sends out a second signal via the cable back to the central control unit. This second signal is then displayed on the monitoring device coupled to the monitor.Type: GrantFiled: May 6, 1998Date of Patent: November 11, 2003Assignee: United Microelectronics Cor.Inventors: Alex Tang, Kuo-Tsai Yen, Chung-Chien Lu, Chien-Hung Hsu
