  • Publication number: 20070050809
    Abstract: According to one embodiment, a system and method for displaying on a user-display system a program comprising a programming content including a plurality of programming content segments and a non-programming content including at least one non-programming content segment. The method includes receiving in the user-display system a first programming content segment of the programming content transmitted from a first source across a computer network, identifying at least one non-programming content segment associated with the first programming content, the identified non-programming content segment received in the user-display system from a second source across the computer network, and displaying the identified non-programming content segment by the user-display system.

  • Patent number: 7178992
    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.

  • Publication number: 20060234564
    Abstract: A connector device (for example, a jack) is provided with a sensing mechanism that detects mating of another connector to the connector device, and differentiates between matching and non-matching connectors. The sensing mechanism generates a signal to indicate that a non-matching connector has been mated with the connector device.

  • Publication number: 20060164998
    Abstract: A TDR (Time Domain Reflectometry) circuit associated with a computer network device monitors a network connection to identify changes in that connection. The disclosed system and method may provide notification when a possible attempt to intercept signals in the network has been detected, and may be automatically controlled to perform periodic monitoring of the network.

  • Publication number: 20050167825
    Abstract: A fuse corner pad is part of an integrated circuit that includes a built-in fuse contact and a plurality of auxiliary pads. The fuse contact is a conductive metallic or metalloid structure that is connected to a fuse element. The fuse contact and fuse element are used inside of the fuse corner pad for programmability (e.g., for security) and/or adjustment (e.g., trimming) of analog and/or digital signals. The fuse contact and fuse element are not required to be bonded to an external electrical connection (such as, a pin or ball). The auxiliary pads provide a variety of functional or non-functional applications, such as testing, probing, programming, and/or circuit adjustment.
