  • Patent number: 7602974
    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.

  • Publication number: 20090019666
    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.

  • Publication number: 20070130394
    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.

  • Publication number: 20040132005
    Abstract: A method of forming a biochip in which a micro-carrier having a bar code or a number code thereon is provided. A surface-modifying step is performed for modifying a surface of the micro-carrier to an aminated surface. A solid-phase peptide synthesis step is then conducted to synthesize a peptide having a specific amino acid sequence on the aminated surface of the micro-carrier or immobilizing an antibody or an antigen on the aminated surface of the micro-carrier. The micro-carrier can be applied on a biological activity analysis or an antibody-antigen interaction analysis, and the results can be read out directly from the bar code or the number code on the micro-carrier.

  • Patent number: 6370067
    Abstract: A memory controller configured according to a delay pair for communicating with a memory device automatically selects optimal delay pairs by testing whether successful communication exists at various values for the delay pairs. The resulting set of delay pairs allowing successful communication are divided into a boundary set and non-boundary set. An optimal delay pair from the non-boundary set is chosen according to its relationship to delay pairs in the boundary set.
