  • Patent number: 8098874
    Abstract: A hanging type earphone with a hinge unit includes an earphone body, a hang member and a hinge unit. The earphone body has a connecting base defining a receiving space. The hinge unit received in the receiving space includes a positioning base, an axis cover and a pivotal axis having a mating portion whose cross-section is a polygon. The axis cover presses against the positioning base to form a pivotal space, one end of the pivotal axis is fixed in the hang member and the other end passes through the pivotal space, the mating portion mates with the side walls of the axis cover, thereby, the earphone body is positioned after rotating relatively to the hang member. Moreover, the pivot axis can be pulled out from the pivotal hole and then inserted into the pivotal space from the opposite direction, so the hanging type earphone can be hung on either ear of the user.

  • Patent number: 7984211
    Abstract: A forced lock-step operation between a CPU (software) and the hardware is eliminated by unburdening the CPU from monitoring the hardware until it is finished with its task. This is done by providing a data/control message queue into which the CPU writes combined data/control messages and places an End tag into the queue when finished. The hardware checks the content of the message queue and starts decoding the incoming data. The hardware processes the data read from the message queue and the processed data is then written back into the message queue for use by the software. The hardware raises an interrupt signal to the CPU when reaching the End tag. Speed differences between hardware and software can be compensated for by changing the depth of the queue.

  • Patent number: 7974480
    Abstract: An Image Signal Processing unit (ISP) has at least one fixed-size line buffer which is smaller than the width of the image buffer. To handle the image data, the image buffer is divided into regions which are sequentially loaded into the at least one fixed-size line buffer of the ISP for processing. Since functions of the ISP operate with neighboring pixels of the target pixel, margins of the regions need to be transmitted as well. After processing by the ISP, the data is encoded which includes a DCT, Quantization, and VLC. The result is then stored in segments in a buffer storage. VLC also inserts a Restart Marker which is used as a pointer to stitch together all the segments thus producing a new and seamless image.
