  • Patent number: 9523470
    Abstract: A simulated flame structure comprises a bracket, a simulated flame element, a first magnetic element and a light-emitting element. The bracket is formed with a position limiting hole. The simulated flame element is restricted in the position limiting hole through a position limiting portion. The first magnetic element is disposed on the simulated flame element. The light-emitting element is disposed on the bracket and outputs light toward the simulated flame element. By magnetic attractive actions between the first magnetic element and a metal element in the position limiting hole, the simulated flame element may be suspended in the position limiting hole and naturally swing relatively to the bracket, thereby achieving visual effects of optimized flame combustion.

  • Publication number: 20120146701
    Abstract: A clock system includes a clock signal generating circuit and a controlling circuit. The clock signal generating circuit is used for generating a primary clock signal and a reference clock signal both derived from an oscillating signal of the clock signal generating circuit. The controlling circuit is coupled to the clock signal generating circuit and used for receiving the primary clock signal under a normal mode and compensating timing information generated from the primary clock signal according to the reference clock signal when the clock system exits a power saving mode. The primary clock signal is de-activated when the clock system enters the power saving mode and is activated when the clock system exits the power saving mode. The clock system can keep a continue clock for system to use when the primary clock signal is gated or power saving mode is entered.
