  • Publication number: 20240079758
    Abstract: An electronic device includes a metal back cover, a metal frame, and a first, second, third, and fourth radiators. The metal frame includes a discrete part and two connection parts. The connection parts are located by two sides of the discrete part, separated from the discrete part, and connected to the metal back cover. A U-shaped slot is formed between the discrete part and the metal back cover and between the discrete part and the connection parts. The first radiator is separated from the discrete part and includes a feed end. The second, third, and fourth radiators are connected to the discrete part and the metal back cover. The third radiator is located between the first and second radiators. The first radiator is located between the third and fourth radiators. The discrete part and the first, second, third, and fourth radiators form an antenna module together.

  • Patent number: 8456094
    Abstract: The present invention discloses a light emitting device open/short detection circuit, which is used for detecting at least one light emitting device string open/short. Each light emitting device string has a first end and a second end, wherein the first end is coupled to a voltage supply circuit to supply electrical power to the light emitting devices. The open/short detection circuit includes: an abnormal voltage detection circuit coupled to the light emitting device strings for receiving voltages of the second ends respectively and generating an abnormal voltage detection signal; a voltage setting circuit coupled to the abnormal voltage detection circuit for setting an abnormal reference level; and a determination circuit coupled to the voltage setting circuit. When the abnormal voltage detection signal is equal to or over the abnormal reference level, the determination circuit generates an open/short detection signal for an abnormal condition detected.

  • Patent number: 7230390
    Abstract: A cold cathode fluorescent lamp (CCFL) assembly includes a pair of CCFLs, and an inverter-type drive circuit. The drive circuit includes a first transformer having a primary winding adapted to be coupled to a power supply module, and a secondary winding with a pair of terminals. The CCFLs are coupled respectively to the terminals of the secondary winding. The drive circuit further includes a push-pull drive circuit coupled to the primary winding of the first transformer, and adapted to be coupled to the power supply module. The push-pull drive circuit excites the primary winding of the first transformer upon receiving power from the power supply module such that power is transferred from the primary winding to the secondary winding, thus activating the CCFLs coupled thereto.
