Abstract: In an Internet Protocol Television (IPTV) system, an IPTV server is configured to receive a request from an IPTV content storage device (CSD) to view a video stream. The IPTV server selects a set of peers for the IPTV CSD, and transmits the set of peers to the IPTV CSD. In the system, a capacity of a fiber to the node (FTTN) switch in a down linking direction is greater than or equal to a sum of a number of simultaneous viewers supported by the FTTN switch plus a number of viewers that receive video streams from peers in the same community.

Abstract: A temperature detecting device includes a current source, a plurality of resistors, a binary counter, a multiplexer, a comparator and a control logic. The current source provides a PTAT current. The resistors provide m voltage signals with ascending or descending voltages. The binary counter generates a binary select signal having (n+1) bits. The m voltage signals are selectively outputted from the multiplexer as a multiplexer output signal according to the binary select signal, wherein 2n<m<2n+1. The comparator is used for comparing the multiplexer output signal with a reference voltage, thereby generating a comparing signal. The control logic is for issuing the start signal. If the comparing signal has a level change, the control logic controls the binary counter to record the binary select signal as a binary temperature signal. The reference voltage does not vary with temperature.

Abstract: A material for producing a conductive composition comprising polymer particles, conductive particles, and a liquid medium. The material is in a liquid/dispersion form until it is cured at which time it forms an electrically conductive composition. The composition contains larger sized polymer particles along with smaller metal conductive filler particles such as nanoparticle-sized filler particles. The larger polymer particles create excluded volume in the material matrix and reduce the percolation threshold of the conductive filler particles to provide a conductive material with a reduced volume fraction of electrically conductive filler. The electrical conductivity of the material is further increased after heat treatment which causes the conductive filler particles to sinter together to form a highly conductive network.
