  • Patent number: 11356105
    Abstract: The invention provides a method for calibrating crystal frequency offset through an internal loop of a central processing unit (CPU), which comprises: outputting an oscillation exciting signal to a crystal circuit by the CPU; producing a clock signal by the crystal circuit; outputting the clock signal through an output port arranged on the CPU by the internal loop; and adopting and connecting a frequency meter to the output port, and receiving and testing the clock signal to obtain a testing result; determining whether a deviation of the clock signal is qualified; if it is qualified, the tester exits subsequently, otherwise the tester regulates the crystal circuit, and then turning to Step S4. The clock signal of the CPU is output at the output port through the internal loop, and then the frequency meter is used for measuring the clock without being influenced by a probe, and the measurement is more accurate.

  • Patent number: 11356147
    Abstract: Techniques are described for accurate tracking of a radiofrequency (RF) carrier for amplitude-modulated signals in unstable reference clock environments. For example, some embodiments operate in context of clock circuits in devices configured for near-field communication (NFC) card emulation (CE) mode. The clock circuits seek to generate an internal clocking signal by tracking a clock reference, such as an RF carrier. In some cases, the clock reference can unpredictably become unreliable for periods of time, during which continued tracking of the unreliable clock reference and/or improper reacquisition can yield appreciable frequency and phase errors in the generated internal clocking signal. Some embodiments implement phase delta detection with time limiting to limit the magnitude of such errors in the internal clocking signal introduced while tracking an unreliable clock reference. Other embodiments provide feedback-pause-control (FPC) to force proper clock reference reacquisition.

  • Patent number: 11342797
    Abstract: A wireless power transmitter system for directing a high energy beam towards receivers fitted with identifying signs. One type of the identifying signs may have asymmetric shape properties, such that their mirror image cannot be matched to their actual shape, even after the image is rotated, tilted or otherwise geometrically manipulated. The system can thus determine whether a detected image of a sign is a true image received directly from said receiver, or is received after the imaged beam has undergone a reflection between the receiver and the transmission system. In the latter case, the system can prevent high power transmission from being directed to a location other than a real receiver, which could be a safety hazard. Other types of identifying signs may be located in or on the borders of different zones of a transmission space, to identify zones where transmission may be allowed or prohibited.
