Abstract: An apparatus is disclosed to increase a breakdown voltage of a semiconductor device. The semiconductor device includes a modified breakdown shallow trench isolation (STI) region to effectively reduce a drain to source resistance when compared to a conventional semiconductor device, thereby increasing the breakdown voltage of the semiconductor device when compared to the conventional semiconductor device. The modified breakdown STI region allows more current to pass from a source region to a drain region of the semiconductor device, thereby further increasing the break down voltage of the semiconductor device from that of the conventional semiconductor device. The semiconductor device may include a modified well region to further reduce the drain to source resistance of the semiconductor device.

Abstract: In a wireless communication system, a multi-source data multiplexing system (e.g., a media access control (MAC)) accepts information packets from a plurality of signal sources, evaluates the relative efficiencies of data transmission, and transmits the information packets in provided grant regions for maximum efficiency. The multi-source data multiplexing system may accept any form of information packet from any form of signal source. The system receives a grant region, typically including a transmission time on a data channel, and inserts an information packet into the grant region. The actual information packet placed in the grant region may be one other than the packet for which the grant region was intended. Further, the multi-source data multiplexing system may fragment an information packet and transmit only a portion of the information packet in the grant region.

Abstract: Systems and methods are provided in which eyewear with time shared viewing is capable of supporting delivery of differing content to multiple viewers/users. The content that is delivered to each viewer includes a respective frame sequence that is displayed on a screen. The frame sequences are mixed when they are displayed on the screen. A lens assembly may be used by each viewer to view the frame sequence that is delivered to that viewer. For instance, a first lens assembly may pass a first frame sequence but not frame sequences other than the first frame sequence. A second lens assembly may pass a second frame sequence but not frame sequences other than the second frame sequence, and so on. The content that is delivered to a viewer may depend on a maturity of the viewer (e.g., whether the viewer's maturity is less than a maturity threshold).

Abstract: Smart routing between peers in a point-to-point link based system begins when a device of a plurality of devices in a point-to-point link interconnected system receives a packet from an upstream link or a downstream link. The processing continues when the device interprets the packet to determine a destination of the packet. If the device is the destination of the packet, the device accepts the packet. If, however, the device is not the destination of the packet, the device forwards the packet on another upstream link or another downstream link without alteration of at least one of: source information of the packet and destination information of the packet.

Abstract: The present invention includes an optical transceiver having a fiber module with an optical data input and an electrical data output. The fiber module further includes a signal detect output that indicates the receipt of valid optical data. A physical layer device having a receive input is coupled to the electrical data output through a switch that is controlled by the signal detect output. The switch passes electrical data from the electrical data output of the fiber module to the receive input when the signal detect output indicates the receipt of valid optical data, and does not pass the electrical data when the signal detect output indicates invalid optical data. By using this configuration, the signal detects pins of the physical layer device are eliminated. In another embodiment, the switch is not utilized, and the electrical data output of the transceiver is ac-coupled to the differential receive input of the physical layer device.

Abstract: An edge enhancer for enhancing edges within a video image, forms an edge enhancement signal of odd harmonics of a sinusoid representative of the edge content in an incoming signal. The edge enhancement signal may be added to a version of the incoming signal, thereby sharpening the edge in the incoming signal. This allows edges to be enhanced, increasing the image's rise-time without adding overshoot. Sharper edges are thus produced in much the same way as a square wave may be formed of odd harmonics of a sinusoid.
