  • Publication number: 20240071656
    Abstract: A circuit protection device includes a first temperature sensitive resistor, a second temperature sensitive resistor, an electrically insulating multilayer, a first and second electrode layer, and at least one external electrode. The first temperature sensitive resistor and the second temperature sensitive resistor are electrically connected in parallel, and have a first upper electrically conductive layer and a second lower electrically conductive layer, respectively. The electrically insulating multilayer includes an upper insulating layer, a middle insulating layer, and a lower insulating layer. The upper insulating layer is between the first upper electrically conductive layer and the first electrode layer. The middle layer is laminated between the first temperature sensitive resistor and the second temperature sensitive resistor. The lower insulating layer is between the second lower electrically conductive layer and the second electrode layer.

  • Patent number: 7916866
    Abstract: An apparatus for descrambling a data retrieved from an optical storage medium comprises a decoder, a memory and a descramble engine. The decoder decodes the data and generates address information corresponding to an address on the optical storage medium, wherein the address responding to a part of the data having been decoded. The memory stores the address information and the part of the data. The descramble engine continuously descrambles the part of the data by retrieving the address information. A method for descrambling a data retrieved from an optical storage medium comprises the following steps: decoding the data; generating address information corresponding to an address on the optical storage medium; storing the address information and a part of the data having been corrected; and descrambling the part of the data continuously by retrieving the address information after the data decoding is interrupted.

  • Patent number: 7836334
    Abstract: A system for transferring data read from a data storage medium. The system comprises a memory unit, a controller, a memory management logic, and an output interface. The memory unit stores the data. The controller compares at least one address of the data with at least one defect address and generates a defect notification signal indicating the comparison result. The memory management logic calculates the amount of the data stored in the memory unit for transfer and generates a calculation signal according to the amount of the data and the defect notification signal received from the controller. The output interface retrieves the data from the memory unit and transfers the retrieved data according to the calculation signal received from the memory management logic.

  • Patent number: 7602655
    Abstract: An embedded system for programming a programmable device including a micro controller and an I/O interface. The programmable device includes a pin set for signal delivery. The micro controller device controls the programmable device via the pin set. The I/O interface receives a program code provided externally. The micro controller executes a command sequence to program the program code into the programmable device via the pin set, and the programmable device uses the program code to provide the specific function. The command sequence may also be provided externally and sent to the micro controller via the well-known general I/O interface.

  • Publication number: 20090187779
    Abstract: The application discloses methods applied to an electronic system capable of operating in a non power saving mode and a power saving mode. According to one of the methods, the idle time when the electronic system is idle in the non-power saving mode is measured. If the idle time equals or exceeds a mode entry time, the electronic system enters the power saving mode. The power down duration when the electronic system stays in the power saving mode is measured. The mode entry time is then modified based upon the power down duration.

  • Patent number: 7480744
    Abstract: A programmable system for storage of one-time programmable information comprises an interface translator and a one-time programmable device. The interface translator receives and translates a command code to program code comprising a sequence of write instructions and a designated data block. The one-time programmable device is coupled to the interface translator, programmed by the write instructions to store the designated data block. The one-time programmable device can only be programmed once, such that the designated data block being stored is fully protected.

  • Publication number: 20080126753
    Abstract: An embedded system and an operating method thereof are disclosed. The embedded system comprises a micro-processor and a co-processor. The co-processor can only process non-interruptible instructions. The micro-processor is powered by an operating system to control the embedded system. When a task requires execution, the micro-processor appoints the co-processor to execute at least one batch command block. The batch command block is compiled with a sequence of non-interruptible instructions. When the task is complete, the co-processor outputs a response signal to the micro-processor.
