    摘要: Methods and apparatus for sensing barrier position in a barrier movement system are disclosed. Electrical apparatus is connected to the barrier and generates a barrier position signal representative of barrier positions which may be used by a controller to detect barrier position. The electrical apparatus can be manually adjusted to reflect a first barrier position such as a closed position. Other barrier positions can be sensed by comparing the barrier position signal to other manually adjustable position signals.

    摘要: A cable tension sensing apparatus is mounted on a wall having a door opening. The jack shaft garage door operator includes a drive unit having an electric motor for driving a jack shaft mounted above a door opening. A pull-up cable drum is connected to the jack shaft and has a multi-strand steel pull-up cable that may be payed out to lower a door or wound up to raise the door. The cable tension sensing apparatus includes a cable guide to retain the cable a substantially fixed distance from the wall and a spring driven cable follower which urges against the cable extending between the drum periphery and the cable guide. An alerting switch is connected to the cable follower and sends a signal indicating loss of cable tension when the cable follower moves beyond a predetermined distance. Additionally, the movement of the cable follower moves a door blocking arrangement to a position to block movement of the door when being raised without use of the motor.

    摘要: Video decoding innovations for multithreading implementations and graphics processor unit (“GPU”) implementations are described. For example, for multithreaded decoding, a decoder uses innovations in the areas of layered data structures, picture extent discovery, a picture command queue, and/or task scheduling for multithreading. Or, for a GPU implementation, a decoder uses innovations in the areas of inverse transforms, inverse quantization, fractional interpolation, intra prediction using waves, loop filtering using waves, memory usage and/or performance-adaptive loop filtering. Innovations are also described in the areas of error handling and recovery, determination of neighbor availability for operations such as context modeling and intra prediction, CABAC decoding, computation of collocated information for direct mode macroblocks in B slices, reduction of memory consumption, implementation of trick play modes, and picture dropping for quality adjustment.

    摘要: An inter mode for encoding a video macroblock is selected. An initial analysis on the macroblock homogeneity is performed to quickly reduce the number of inter modes for which motion estimation and rate distortion calculation are to be performed. An inter mode is selected based on these calculations and sub-pixel motion estimation, at various sub-pixel interpolation granularities, is performed only on the selected inter mode. Sub-pixel motion estimation may be skipped for macroblocks that exhibit relatively low distortion at the integer pixel level.

    摘要: Transform based distortion cost estimation, which may be used to calculate a rate distortion cost associated with a mode for encoding a macroblock, is described. In one embodiment of the invention, a distortion value for a particular mode is estimated within the transform domain, which allows for the elimination of both inverse transformation and inverse motion functions in this calculation. A spatial domain residual of an encoding mode is estimated by identifying a difference, within the transform domain, between a motion compensated prediction residual of a macroblock and its corresponding reconstructed signal. The estimated spatial domain residual may then be used in distortion matrix computations to estimate a distortion level, within the transform domain, for an encoding mode.

    摘要: In a social networking system environment, users can give another user credits, a scarce commodity, as part of commenting on content posted by the other user. These credits can be used as a peer-to-peer recommendation signal, and they can also be used as input to a decision engine that determines what content to display in a highlights section that will be viewed by a wider audience and increasing the likelihood of further engagement with the content. Credits in a social networking system environment have scarcity value. In various embodiments, in order to increase the number of credits in the system, users buy them or an administrator distributes them. In some implementations, the total amount of credits in the system can decrease if a user cashes out the credits for real money. In some implementations, credits can be used to buy virtual or real-world gifts.
