  • Patent number: 7701466
    Abstract: Systems and methods for processing signals are disclosed. The method may include, in a communication device that includes a chip operating to processing video signals, receiving video data from a camera. The received video data may include alternating YUV formatted video data and RGB formatted video data. The received video data may be separated into separate YUV images and separate RGB images. The separate YUV images may be transferred to a first device, and the separate RGB images may be transferred to a second device. The camera may be configured to generate the video data that includes alternating YUV formatted video data and RGB formatted video data. The separate YUV images may be DMA transferred to the first device. A DMA controller may be configured to alternately transfer the separate YUV images and separate RGB images. The alternate transfer via the DMA controller may occur without assistance from on-chip processor.

  • Patent number: 7429992
    Abstract: Providing accelerated video processing in a communication device may comprise receiving video data from a video source on a chip, determining a first format for at least a portion of the received video data, and determining a second format of at least a remaining portion of the received video data. At least a portion of the received video data having the first format may be routed to a first device for processing and at least a remaining portion of the received video data having the second format may be routed to a second device for processing. The portion of the received video data with the first format may comprise RGB format, while the remaining portion of the received video data with the second format comprises YUV format. The received video data comprises images with alternating video formats, which are accordingly routed to the first or second device for processing.

  • Publication number: 20070057798
    Abstract: The invention, a voice-operated alarm system, includes an alarm and a receiver. The alarm is comprised of a microphone unit, a voice detector, a noise reduction unit, a speech recognizer or a keyword spotter which can recognize predefined keywords, and a signal transmitter. The speech recognizer and the keyword spotter can be speaker dependent, speaker independent, or both. A speaker-dependent system needs training, while a speaker-independent system does not. A receiver is located near the alarm and is connected to a telephone or data network. The receiver further communicates with the emergency monitoring center. Furthermore, the alarm system can also be implemented as a wireless phone with keyword spotting/recognition function. In this embodiment, the alarm user can communicate with the operators directly, like a cell phone, but the dial up function is replaced by uttering keywords. In this implementation, the receiver may not be necessary.

  • Publication number: 20040261359
    Abstract: A binding apparatus for packaging and paper recycling comprises of four separate holding trays, four legs connected to the trays, and several frames connecting the legs. Each of the trays holds a corner to a quarter of the area of the papers or materials which need to be bound. The four trays work together to hold papers or any materials that needs to be bound but there is a clearance between any two pairs of the trays. Given the clearance between the trays and the clearance between the frames and trays, human hands, ropes, or binding tools can go through to bind the papers without touching any one of the trays and without moving the objects which needs to be bound. The ropes are placed in the clearances between trays. Once the binding is finished, a stack of bound papers or materials can be removed directly from the top of the binding apparatus without moving the apparatus. The apparatus can be used for paper recycling, as magazine rack, or as furniture for decoration.
