Abstract: A method and apparatus are disclosed for reducing a transmission rate for retransmission of a current frame in a wireless communication system. The reduced transmission rate increases the probability that the current frame is correctly transmitted and acknowledged. The transmission rate is progressively reduced for the current frame to avoid the expiration of the frame's retry count, while not affecting the transmission rate of subsequent frames. The next frame should be transmitted at the highest rate permitted by the signal quality. A disclosed retry count expiry avoidance algorithm increases the reliability of a retransmission by lowering the transmission rate for the current frame when an acknowledgement is not received. When an acknowledgement is not received, the transmitting station proceeds to a retransmitting state where the transmitting station first attempts to retransmit the frame at the same rate.

Abstract: A system for accurately determining whether a work piece such as a plastic molded bottle cap is defective from quality norms and removing those defective pieces from a stream of work pieces includes a feed conveyor for serially delivering work pieces where adjacent work pieces are in contact with each other. The feed conveyor delivers these work pieces onto an inspection conveyor with a plurality of air holes. Air is forced through the air holes to impinge upon the work piece and thus rapidly accelerate them away from the adjacent work piece it was in contact with and move through an inspection station. An air blower provides pressurized air through the air holes to continue accelerating and separating the work pieces as they move. The inspection station includes a camera to image each work piece. The camera communicates these images to a processing unit such as a computer that can rapidly compare the image to a set of quality control standards each work piece should meet.

Abstract: An offline synchronous switching regulator is proposed for improving the efficiency thereof. Switches are coupled to switch a transformer and generate a switching signal at a secondary side of the transformer. A switching circuit is coupled to an output of the regulator to generate pulse signals in response to the switching signal and a feedback signal. Pulse signals are utilized to control a synchronous switch for rectifying and regulating the regulator. The synchronous switch includes a power-switch set and a control circuit. The control circuit receives pulse signals for turning on/off the power-switch set. The power-switch set is connected in between the transformer and the output of the regulator. A flyback switch freewheels an inductor current and can be turned on in response to the off state of the power-switch set whose on-time is correlated to the on-time of the power-switch set.

Abstract: A method for watermarking a circuit design layout based on frequency or number of geometric structures. The method includes dividing a circuit design layout into a plurality of segments or tiles. Certain segments are selected, and within these selected segments, a router alters the number of geometric structures, such as vias and jogs, of the circuit design layout in the selected segments to form the watermark without relying on a netlist. The number of geometric structures is changed slightly so that a random sampling of segments would not identify the watermark since the variations would not be detectable or would be within acceptable variances, but the watermark would be readily identified if the selected segments are known. The watermark or portions thereof can be used to encode one or more data bits.
