  • Patent number: 11252550
    Abstract: Techniques are described for frequency-division-coordination of automatic power control (APC) in a transceiver of a near-field reader. Such frequency-division-coordinated APC (FDC-APC) can enable continuous APC updates concurrent with communication frames to achieve field strength specifications without conventional degradations in communication reliability. For example, a transceiver implements a FDC-APC loop that received a detuning signal from signals received and/or transmitted over a near-field communication link, generates an error signal by comparing the detuning signal with a reference detuning level, and updates a power control signal according to an update frequency (e.g., corresponding to a APC loop bandwidth) that is a function of at least a filter frequency profile and is out-of-band with respect to a modulation frequency band. Modulated signals can be transmitted over the near-field communication link according to variable power settings controlled to the power control signal.

  • Patent number: 11243506
    Abstract: A novel and useful acknowledgement and adaptive frequency hopping mechanism for use in wireless communication systems such as IO-Link Wireless. One or two additional acknowledgement bits are added to packet transmissions. One is a current acknowledgment bit which indicates whether a packet was successfully received anytime during the current cycle. The second bit is a previous acknowledgment bit which indicates whether packets were received successfully anytime during the previous cycle. An adaptive hopping table is constructed using a greedy algorithm which chooses frequencies with the best PER for transmission of higher priority packets, while equalizing the PER products across cycles. A last resort frequency mechanism further improves transmission success by switching to a better performing channel for the last subcycle when previous attempts to transmit a high priority packet have failed.

  • Patent number: 11201506
    Abstract: A first power receiving apparatus observes a power transfer signal from a power supply apparatus, and detects whether power transfer is being performed between the power supply apparatus and a second power receiving apparatus. When the power transfer is being performed between the power supply apparatus and the second power receiving apparatus, a waveform of the signal is deformed with a predetermined pattern. The second power receiving apparatus detects deterioration in power which is received from the power supply apparatus and detects whether the waveform of the signal changes with the predetermined pattern within a predetermined time after detecting the power deterioration. When detecting the change in the waveform of the signal with the predetermined pattern, the second power receiving apparatus determines that the first power receiving apparatus is in a power suppliable range of the power supply apparatus.

  • Patent number: 11184153
    Abstract: Methods and apparatuses are presented to generate, and verify reception of, ultra wideband (UWB) communications, e.g., to perform secure UWB ranging. Verifier and prover messages may be encoded on top of random cryptographically secure training sequence (STS) of pulses, organized in blocks such that a given block corresponds to a given message bit. In some scenarios, a first STS may be encoded using a verifier message not known to a recipient device. A second STS may be received from the recipient device, encoded with an unknown prover message. A third STS may also be received, encoded with an authentication message generated using the verifier message and the authentication message. Verification of the authentication message can therefore confirm that the recipient device received the first STS, and that the recipient device is the authentic source of the second STS. Thus, the second STS may be relied upon, e.g., for ranging calculations.
