    摘要: To improve the yield, lifetime and driving voltage of the micro scratch drive actuator (SDA), this invention proposes a novel layout design including the etch holes and flange structure designs.Once the etch holes added to the layout of conventional SDA plate, the releasing of structure layer can be accelerated and the accumulated residual charges in the front end of SDA plate is reduced. In this innovative design, a longer lifetime and lower driving voltage of the SDA device can be achieved. On the other hand, adding the flange structure design in the corner of the beam-to-plate conjunction can improve the flexural rigidity of the narrow polysilicon supporting beam which will further enhance the yield of the SDA device and reduce the crack failure under actuating situation.

    摘要: Based on the voltage-division theory, this invention proposes a new method to decrease the driving voltage of the micro scratch drive actuator (SDA) by using an ultra-low resistivity silicon wafer as substrate. This patent has compared two SDA actuators with the same layout and fabricating processes but under different resistivity of substrate. The SDA fabricated on the ultra-low resistivity silicon wafer has demonstrated a lower driving voltage of only about 4˜12 Vo-p. However, the conventional SDA using normal silicon wafer needs higher driving voltage (30˜75 Vo-p), thus has lower probability for commercial applications. On the other hand, this invention presents a new SDA process to overcome the inherent 2 μm line-width limitation of conventional mask aligner with 4360 Å UV wavelength light source (g-line) and further to reduce the driving voltage of SDA.

    摘要: A video decoder performs a sequential error handling process to detect and conceal errors within a corrupted data segment of video data units. The decoder sequentially decodes a current data unit. Upon detecting an error, the decoder sets an error flag and resynchronizes decoding at the start of the next unit. If the error flag is set, the video decoder identifies the end of the corrupted data segment based on the start of the later unit. The decoder conceals data between the start of the current unit and the end of the corrupted data segment. If the error flag is not set, the decoder may decode the remainder of the current unit and proceed to decode the next available unit without performing error handling and concealment for the current unit. The decoder also may address reference unit mismatches caused by lost video data units.

    摘要: One technique for implementing error control in response to a video data error comprises receiving an indication of a video data error from a video decoder, determining whether the video data error occurred on a reverse link of a wireless network between a video encoder and a network device, and applying error control in response to the video data error if the video data error did not occur on the reverse link. For example, the indication of the video data error may include a first sequence number (SN) of a packet comprising lost data, and determining whether the video data error occurred on the reverse link may include comparing first SN with a second SN of a packet associated with a most recent RL error.

    摘要: The disclosure relates to techniques for video packet shaping for video telephony (VT). The techniques can be used to prioritize audio packets to reduce audio delay. Channel conditions, excessive video content, or both can cause delays in audio transmission. When reverse link (RL) throughput is reduced, video packet size can overwhelm the RL and increase audio delay. The video packet may consume an excessive number of MAC RLP packets, resulting in delays between successive audio packets. The size of each video packet is adjusted so that audio packets are prioritized for transmission without substantial delay. The video packet size may be controlled based on channel conditions. The audio can be conveyed without substantial delay, even though the video may suffer from delay due to channel conditions. Although video may be compromised by channel conditions, video packet shaping ensures that the VT parties are able to smoothly carry on verbal conversation.

    摘要: An apparatus performs efficient coding techniques to more efficiently locate motion vector data within neighboring video data units. The apparatus comprises a motion vector (MV) location unit that includes a look-up table (LUT), where the MV location unit obtains video data defining a plurality of video data units and processes the plurality of video data units. The apparatus further includes a geometric resolution unit that determines, while processing a current one of the plurality of video data units, which of the plurality of video data units neighbor the current video data unit. The MV location unit then accesses, for each of the neighboring video data units, the LUT to determine a location of a motion vector within a section of the video data to which the neighboring video data unit is associated.
