  • Publication number: 20240118199
    Abstract: An optical analysis system and an optical analysis method, which simply change driving electric currents of light-emitting units via using a control and process unit, so that a wavelength range and a peak wavelength of an irradiated light generated by each light-emitting unit may be fine-tuned. A plurality of irradiating lights with different wavelength ranges and peak wavelengths are irradiated to the object to be tested in different times, so that merely fewer light-emitting units may be used to improve a detection resolution and a detection accuracy of a spectrum of the object to be tested.

  • Publication number: 20170289014
    Abstract: The present invention relates to a redundancy system of routing paths and method thereof. By establishing corresponding routing paths from different ports of routers in a ring network to a terminal in advance and transmitting the identical packet to the terminal by the different ports in the different routing paths simultaneously, the time of reestablishing the routing paths may be saved when one of the routing paths is broken, so as to improve the routing efficiency.

  • Publication number: 20170230231
    Abstract: In one embodiment of the invention, a redundancy system/method based on the Virtual Router Redundancy Protocol, it includes a master router and at least one backup router preselected. The master router and at least one backup router may have a weight value and Virtual LANs composed of same routing path. A communication representative is chosen from one of the Virtual LANs of each of the master router and the backup router. The communication representative of the master router may continuously transmit the advertisement packet to that of the backup router, and continuously transmit an Address Resolution Protocol table to the backup router. When a communication representative of the backup router doesn't receive the advertisement packet, all the Virtual LANs of the master router will be judged abnormal, and the master router may be replaced, therefore enhance the redundancy switching efficiency and increase the number of the available Virtual LANs.

  • Patent number: 7483488
    Abstract: The invention is related to methods and apparatus that advantageously improve picture quality in a video encoder, such as an MPEG video encoder. The picture quality of a video encoder can be compromised by bit stuffing. Bit stuffing is a technique that is commonly used when encoding to resolve buffer underrun problems. However, bit stuffing can introduce instabilities in the encoding process. Embodiments of the invention advantageously stabilize the encoding process due to bit stuffing, and thereby improve picture quality.

  • Patent number: 7406124
    Abstract: The invention is related to methods and apparatus that can advantageously be used in a video encoder to improve picture quality, to improve the speed of encoding, and the like. One embodiment of the invention advantageously computes activity measures using an efficient L1-norm, which can advantageously be relatively quickly computed by selected microprocessors. Another embodiment of the invention advantageously allocates bits to macroblocks of a picture based at least in part on the motion activities of the macroblocks.

  • Patent number: 7388912
    Abstract: Methods and apparatus are provided to advantageously improve bit rate control in a video encoder, such as an MPEG video encoder. The targeted bit allocation for a picture to be encoded is advantageously varied based on an occupancy level of a buffer model, such as a video buffer verifier (VBV) buffer model.

  • Patent number: 7197072
    Abstract: The invention is related to methods and apparatus that advantageously improve picture quality in a video encoder, such as an MPEG video encoder. Scene changes typically occur relatively frequently in picture sequences, such as movies. One embodiment of the invention detects a scene change within a group of pictures and allocates bits within the group of pictures in response to the detected scene change without changing a predetermined structure for the group of pictures.
