  • Patent number: 10763587
    Abstract: A system, apparatus and method are disclosed for communicating between a short range wireless (WLAN) user device, such as a wearable, phone, or tablet, with a base station. Traditional low power communication (e.g., WLAN, WiFi, Bluetooth, cellular links, etc.) involve an inefficient amplification process of a signal from the WLAN user to the base station, whereby significant power must be expended in the WLAN user device making it unsuitable in many applications. A reflector link paradigm is disclosed in which the user device communicates by modulating the extent of signal reflected back to the base station. An enhanced reflector is also disclosed which overcomes adverse effects of ambient reflections.

  • Patent number: 10749616
    Abstract: A method for a phase calibration in a frontend circuit of a near field communication (NFC) tag device is disclosed. An active load modulation signal is generated with a preconfigured value of a phase difference with respect to a reference signal of an NFC signal generator device. An amplitude of a test signal present at an antenna of the NFC tag device is measured. The test signal results from overlaying of the reference signal with the active load modulation signal. The following steps are repeated: modifying the value of the phase difference, providing the active load modulation signal with the modified value of the phase difference, measuring an amplitude of the test signal and comparing the measured amplitude with the previously measured amplitude until the measured amplitude fulfills a predefined condition. The value of the phase difference corresponding to the previously measured amplitude is stored.
