  • Patent number: 11431523
    Abstract: An input/output (I/O) and control system for long distance communications and industrial applications having a bus and protocol for communications between field devices and a channel generator for monitoring and control of the field devices. The channel generator produces an offset square wave of configurable frequency on the bus, and sends a synchronization pulse of selected duration at the start of each bus scan cycle in a pulse train cycle to reset counters in the field devices before the bus scan cycle is repeated, to ensure field devices are synchronized, transmitters transmit on the correct channel, and receivers sample the pulse cycle at the correct time. Changing the synchronization pulse length increases bandwidth for shorter, less noisy and more stable systems and inversely decreases bandwidth for increased noise immunity and distance for longer, noisier and less stable systems.

    Abstract: An electronic device may include a radio that generates a first maximum power based on a radio-frequency exposure (RFE) budget. The radio may transmit signals subject to the first maximum power during a subperiod of an averaging period and may generate an instantaneous RFE metric value based on an antenna coefficient and the conducted transmit power of the antenna during the subperiod. The radio may generate a consumed RFE value by averaging the instantaneous RFE metric value with previous instantaneous RFE values from the averaging period, may generate a remaining budget based on the consumed RFE value, may generate a second maximum transmit power based on the remaining budget, and may transmit signals during a subsequent subperiod subject to the second maximum power. Time-averaging the RFE metric may serve to optimize performance of the radio relative to scenarios where the radio performs time-averaging of conducted TX power.

  • Patent number: 11196508
    Abstract: A system and method for characterizing performance of a terminal radio. The method includes obtaining a plurality of SNR feedbacks by, for each input power level of varying input power levels of the terminal radio, estimating an SNR (signal-to-noise ratio) associated with a respective input power level for a burst sent from the terminal radio to a gateway, where each of the SNR feedbacks may include an estimated SNR and the respective input power level; and determining a RC (radio characterization) of the terminal radio based on where the SNR feedbacks start deteriorating without indicating a saturated response at the gateway, where bursts are transmitted at a selected frequency with a selected SYMCOD (symbol, modulation and error coding scheme).

  • Patent number: 11190249
    Abstract: For a system with multiple Antenna Elements, AEs, to be used to transmit multiple symbols to multiple user equipments, UEs, and with multiple time sample positions, where the symbols occupy a time-frequency resource space and wherein at least some of the AEs are powered by constrained RF chains having functionalities that are simplified relative to full RF chains, precoder coefficients are generated for the multiple AEs taking into consideration multipath components of a signal to be transmitted from the multiple AEs to the multiple UEs. The generating forms precoder coefficients for individual ones of the constrained RF chains at corresponding certain time sample positions of the symbols. The signal is transmitted from the multiple AEs to the multiple UEs using FDMA at least by applying the generated precoder coefficients to the multiple AEs over the multiple time sample positions and time-frequency resource space of the symbols.

  • Patent number: 11152972
    Abstract: A power line communication sender generates a command signal that comprises a series of alternate first level voltage signals and second level voltage signals, while the time periods of each first level voltage signal and each second level voltage signal are determined according to the value of each corresponding bit in a command information. A power line communication receiver is connected to the sender through power lines to receive power and command signals. When the receiver receives the command signal, the time periods of each first level voltage signal and second level voltage signal is calculated to record each bits of the command signal. Since the information is carried in every first level voltage signal and second level voltage signal, it requires only half the time and requires no quick switching in every binary bit of the transmitted signal, therefore efficiency is improved and signal distortion is lowered.

  • Patent number: 11139872
    Abstract: A network node signals to a wireless communication device which precoders in a codebook are restricted from being used. The network node in this regard generates codebook subset restriction signaling that, for each of one or more groups of precoders, jointly restricts the precoders in the group by restricting a certain component (e.g., a certain beam precoder) that the precoders in the group have in common. This signaling may be for instance rank-agnostic signaling that jointly restricts the precoders in a group without regard to the precoders' transmission rank. Regardless, the network node sends the generated signaling to the wireless communication device.

    Abstract: A cognitive loudspeaker system includes a control station (CS) that broadcasts clock control messages and separate playback messages to a plurality of sound production stations (SPSs). The clock control messages are generated in response to a CS clock signal. Each SPS generates a corresponding local conductor clock signal in response to the received control clock messages and a local SPS clock signal, such that all of the local conductor clock signals are synchronized. Each SPS also generates local digital playback samples in response to the received playback messages. The local digital playback samples are written to an output buffer in response to the local SPS clock signal, and are read from the output buffer in response to the local conductor clock signal.

  • Patent number: 11101705
    Abstract: Timing Acquisition Module (TAM) configured for use in or associated with a WTPS and associated methods, apparatus, and systems. The TAM is configured to receive encoded beacons broadcast by wireless power receiver clients requesting power on demand. The TAM decodes the encoded beacons to identify which client broadcast the beacon and notifies the WPTS that a client is requesting power, along with an identifier of that client. In response, the WPTS transmits wireless power signals to the client to service the power request. The WPTS and client may use separate beacons or signals to command the client to broadcast its WPTS beacon, whereby phases of the beacon signal are detected by antennas in the WPTS antenna array and processed to direct the wireless power signals from the WPTS to the client. Multiple apparatus including a combination of a WPTS and TAM may be implemented in a wireless power environment in a cooperative manner, enabling a client to move within the environment while supporting power on demand.
