    摘要: A movement of a small picture block in a frame of video signals is provided by recursively applying a gradient method to a picture block in a present frame and a preceding frame to provide a series of sub-movements until said sub-movement decreases less than a predetermined value, and the resultant movement is obtained by the sum of the sub-movements. The present invention provides high accuracy in estimation of movement of a block in a picture as compared with a conventional gradient method, and is attractive in hardware implementation.

    摘要: A computational algorithm provides new and effective interference cancellation of the in-band spurious signals for the Orthogonal Frequency Division Multiplex (OFDM) transmitters. This new interference cancellation transmits non-zero tones may be used to cancel the interference generated by the modulated data signals. This minimizes the number of tones used and maximizes the interference suppression achieved at the same time. The technique described is one of active interference cancellation (AIC).

    摘要: A new display system and method is described, utilizing a cellular telephone having digital camera capability and a television linked directly over a UWB wireless signal forming a UWB wireless video pico-net. The system utilizes a digital camera unit to capture picture or video images for UWB transmission directly to the television acting as a pico-net host controller, either independently or together with the cellular telephone operating as a pico-net child. The display system comprises and one or more remote devices and a host display communicating on a UWB wireless network. The host display comprises a display for presentation of the picture or video images and a UWB transceiver for processing image data from the picture or video images, for selectively sending and receiving the image data based on a request from the child. The one or more remote devices comprise a digital camera for capturing the picture or video images and another UWB transceiver as used in the host display. The host display has a generally larger display for improved presentation of the captured picture or video images useful and amusing for group, party, wedding, and conference viewing, or simply for enhanced personal enjoyment. For picture or video image sharing, the system further facilitates downloading the current picture or video images from the host display television to a requesting cellular telephone or digital camera equipped with the UWB transceiver. The UWB display system provides sufficient bandwidth to support numerous such download requests simultaneously, while utilizing a transmission technology having minimal power consumption.

    摘要: The disclosed invention is a computer-implemented method for registering triggers for processing at the end of each transaction occurring in a database. This method positions a class where a given object exists; and for each trigger in the class, a determination is made if the trigger is in a trigger list of an object link. If it is not, a determination is made if a given object is in an object link of a transaction. If it is not, then the given object is inserted into the object link of the transaction; and then the trigger is inserted in a list of the object link. These steps are repeated until all triggers in the class have been processed. A determination is next made if there is a superclass of the class. If yes, then a superclass, is positioned and the steps are repeated for each trigger in the superclass (i.e., polymorphic trigger). Finally, if no superclass of the class exist, then the method is exited.
