    摘要： The invention relates to earth connections to workpieces particularly a workpiece to which an arc is to be struck, and more particularly to a workpiece that is underwater. It is of considerable importance that a workpiece is properly connected to earth, and that the impedance of the connection is not such as will elevate dangerously the voltage on the workpiece. The objective of the invention is to solve this problem, an objective met by an earth connection for workplaces that comprises a loop in the connection of the workpiece to earth, the loop being connected at each end to and being completed by the workpiece, and there being a sensor means to sense current flowing in the loop above a predetermined level.

    摘要： A protective cage for footwear bladders is disclosed. The protective cage includes a cage base and a plurality of support members that extend outwardly from the cage base. The support members extend across the side wall of the bladder to protect the device from abrasion and to prevent fatigue. The use of the support members, which selectively bend and buckle under loaded conditions, control the amount of perimeter deflection of the bladder, while allowing for complete deflection at the center of the bladder.

    摘要： A network-based CODEC (coder-decoder) includes an echo canceler. This CODEC recognizes the presence of a data call by detecting predefined signaling portions of a modem handshaking process. For each detected data call, the CODEC uses a stored channel model for performing echo cancellation during the data call. The CODEC trains off-line during selected segments of the modem call and then stores the new channel model for use in a future data call.

    摘要： A television receiver which is coupled to a digital VCR to receive an ATSC-encoded multi-program stream containing video, audio and data programs. The receiver recognizes one of the data programs as containing computer software for the digital television receiver, extracts the data program from the multi-program stream into a memory area which is separate from the memory areas used to decode the audio and video programs and then uses data in the extracted data program to update information which controls the operation of the television receiver. The television receiver includes a microprocessor which is coupled to a video processor via an IC bus. The video processor includes registers which are coupled to the IC bus. The microprocessor updates these values from the information in the extracted data program. The extracted data program may include a program image for the operational software for the microprocessor and may replace the operational software to update the operation of the television receiver. Alternatively, the extracted data program may include programming which applies to video and audio data that is recorded on the video tape and allows a user to interact with the presentation of the video and audio data.
