  • Patent number: 10043383
    Abstract: An infrared (IR) emission and reception circuit, which is composed of three parts, an IR transceiver circuit, a carrier-smoothed circuit, and a signal recognition circuit. The IR transceiver circuit receives an outside IR signal, converts it to an electrical signal, and then amplifies and shapes the electrical signal to form a carrier frequency read signal; the IR transceiver circuit also emits an IR signal outward. The carrier-smoothed circuit receives the carrier frequency read signal, filters out the carrier to form a carrier-smoothed signal, and outputs it to the signal recognition circuit. The signal recognition circuit receives the carrier-smoothed signal, and converts it to an IR recognition signal to output to the electronic-device processor. The electronic-device processor receives the carrier frequency read signal to recognize the carrier frequency of the outside IR signal, and also receives the IR recognition signal to learn IR control codes of the outside IR signal.

  • Patent number: 8839024
    Abstract: Embodiments of the invention provide a device and method for warm booting whereby data restoration occurs at the powering-on of the host, and can therefore be performed by the boot disk. Specifically, when the system is powered on, a backup controller will send a notification to a DMA controller indicating the data restoration is needed. The backup controller will automatically resorts contents of a backup storage device to main memory. During the process, when the host requests data, the DMA controller reads the data from the backup storage unit and sends it to the host. Then, once data restoration is complete, normal operations can commence.
