    Abstract: An electronic apparatus with power over coaxial cable (PoC) function including a transmission port, a low-pass filter, a dynamic impedance circuit and a switching power converter is provided. The transmission port is coupled to a coaxial cable. The low-pass filter is coupled to the transmission port to receive a mixed signal from the coaxial cable and filter the mixed signal to obtain a first power. The dynamic impedance circuit is coupled to the low-pass filter to receive and store the first power and provide a second power accordingly. The switching power converter is coupled to the dynamic impedance circuit to receive the second power and convert the second power to an operation power.

  • Patent number: 9712368
    Abstract: A chip-to-chip communications circuit which is particularly well-suited for short range communication (less than a few inches) from one integrated circuit (chip) to another is presented. The circuits preferably utilize multi-frequency quadrature amplitude modulation (QAM) mechanisms for converting digital data bits from a parallel form into a serial analog stream for communication over a chip I/O connection. Differential current mode modulation in the transmitter, and demodulation in the receiver, are utilized which reduce latency and power-consumption while increasing manufacturing yields and resilience to process variations.

  • Patent number: 9705564
    Abstract: Spatially Enabled Communication technologies are disclosed. A proximity boundary can be defined by a communication range of one or more SRC devices configured to communicate using near field magnetic induction (NFMI) using at least two antennas to provide magnetic induction diversity. A data block can be securely communicated by interspersing the data between an short range communication (SRC) device for near field magnetic induction (NFMI) communication within the proximity boundary and a radio frequency (RF) radio for RF communication. Data received on the SRC device and the RF radio can be reassembled to form the data block.

  • Patent number: 9703908
    Abstract: A method to generate a reduced delay twinaxial SPICE model is provided. The method may include measuring near-end S-parameter components and far-end S-parameter components of a twinaxial cable, reducing an original time delay of the far-end S-parameter components by multiplying each of the far-end S-parameter components by a complex exponential based on an equivalent delay length, a signal frequency, and an effective dielectric constant, simulating a signal transmitted across a twinaxial cable by running a 4-port SPICE model using the near-end S-parameter components and the multiplied far-end S-parameter components, and recording a magnitude and a phase of the transmitted signal with respect to frequency as outputs of the reduced delay twinaxial SPICE model.

  • Patent number: 9678133
    Abstract: A new patch cord connection in a communications network may be automatically identified by using a plug insertion/removal sensor to detect the insertion of a first plug into a first connector port of a patch panel. An electrical cable diagnostic test is used to detect an insertion of a second plug into a first connector port on a network device. It may be inferred that a new patch cord connection has been established between the first connector port of the patch panel and the first connector port of the network device based on the consecutive detections of the insertions of the first and second plugs.

  • Patent number: 9660759
    Abstract: A method and apparatus for an orthogonal frequency division multiplexed (OFDM) communication system for communication in the presence of cyclostationary noise is provided. A receiver receives from a medium a channel measurement packet of a communication channel. The channel measurement packet has a measured transmission characteristic. The measured transmission characteristic of the received channel measurement packet is compared to a defined transmission characteristic to provide a comparison. A modulation coding scheme (MCS) map referenced to a phase of a cyclostationary noise period of the medium is generated based upon the comparison. The MCS map is sent to a transmitter via the medium. Signals including packets that have been mapped to subcarriers based on the MCS map are received from the medium. Subcarriers of the signals received from the medium are demapped using the MCS map referenced to the phase of the cyclostationary noise period of the medium.

The WFM waveforms are transmitted through a segment of propagation to a receiver segment; wherein the segment of propagation includes a plurality of UAV based transmission channels among the WFM waveforms; wherein the WFM waveforms are transmitted over the transmission channels; wherein the receiver segment receives the WFM waveforms from the transmission channels. Demodulation is performed on the received WFM waveforms to convert the received WFM waveforms to received WFM signals individually. A wavefront de-multiplexing transform is performed on the received WFM signals to recover individual desired signals.
