Abstract: A system and bent-pipe transponder component for determining a location of an individual or object in three dimensional space. The system includes a transmitter configured to transmit a first wireless electromagnetic signal at a first frequency and at least one transponder that is configured to responsively emit a second wireless electromagnetic signal having a second frequency that is frequency-shifted from the first frequency. An included receiver detecting the first and second wireless electromagnetic signals is configured to provide an output of location information for the at least one transponder. A bent-pipe transponder component may include a receiving antenna, an emitting antenna, and a frequency shift stage comprising an oscillator and a first mixer, with the frequency stage mixing a received first wireless electromagnetic signal with the output of the oscillator via the first mixer to produce the emitted second wireless electromagnetic signal.

Abstract: A system for multiplexing a transport packet and an Ethernet packet comprises a transport interface for receiving a transport stream comprising the transport packet and a network interface for receiving a network stream comprising the Ethernet packet. The system comprises a packet identifier coupled to the transport interface for filtering the transport stream and selecting the transport packet and a date formatter coupled to the network interface for creating a transport header appended to the Ethernet packet. The system further comprises a multiplexer for receiving the transport packet from the packet identifier, for receiving the Ethernet packet from the data formatter, and for multiplexing the transport packet and the Ethernet packet comprising the transport header.

Abstract: A delay line calibration circuit and method are provided in which a programmable master delay line drives a delay clock and has a propagation delay that is a function of a delay setting. A delay counter is clocked by the delay clock and has a delay count. A reference counter is clocked by a reference clock and has a reference count. A control circuit controls the delay and reference counters, compares a representation of the delay count to a representation of the reference count and responsively generates a modified value for the delay setting to reduce a difference between the representations of delay count and the reference count.
