  • Patent number: 11368038
    Abstract: A charging receiver device adapts wireless charging receiver loading. The charging receiver device receives energy wirelessly transferred from a wireless charging coil of a charging transmitter device. The charging receiver device includes a charger circuit electrically coupled to a wireless charging receiver coil to receive the charging power. The charging power is a function of a rectified receiver voltage at the charger circuit. A received power monitoring circuit monitors the rectified receiver voltage at the charger circuit, detects a deviation of the monitored rectified receiver voltage from a target rectified receiver voltage for the charging receiver device, and decreases a charge current output from the charger circuit to increase the rectified receiver voltage toward the target rectified receiver voltage, responsive to determining that the detected deviation indicates that the monitored rectified receiver voltage is less than the target rectified receiver voltage.

    Abstract: Various embodiments of the present technology relate generally to wireless power systems. More specifically, some embodiments relate to the use of time reversal techniques utilizing time diversity (e.g., different multipath arrivals at the same antenna) to achieve coherency from the same transmission node. For example, instead of initiating outgoing transmissions (e.g., power signals) at the same time, various embodiments can initiate the outgoing signals from the various antennas in a staggered timing that is a reversal of the arrival times of an incoming signal. As a result of staggering the start of the outgoing signals, the signals will arrive at the destination at approximately the same time even though they have traveled different paths having different propagation delays.

  • Patent number: 11322961
    Abstract: The embodiments set forth a technique for coordinating notifications across computing devices placed onto a wireless charging apparatus. According to some embodiments, the technique can involve the wireless charging apparatus (1) receiving, from a first computing device, first information that includes (i) a first unique identifier (ID) associated with the first computing device, and (ii) one or more unique IDs that are each associated with a respective auxiliary computing device known to the first computing device. Subsequently, the wireless charging apparatus can receive, from a second computing device, second information that at least includes a second unique ID associated with the second computing device. Finally, the wireless charging apparatus can, in response to determining that the second unique ID is included in the one or more unique IDs, and cause both the first and second computing devices to display respective notifications in a coordinated manner.

  • Patent number: 11316361
    Abstract: A novel semiconductor device or a semiconductor device capable of preventing overcharging is provided. A power receiving portion has a function of generating a signal for canceling a wireless signal transmitted from a power feeding portion when the charging is completed. Specifically, when the remaining battery capacity of the power receiving portion is one hundred percent or higher than or equal to a predetermined reference value, the power receiving portion has a function of generating an electromagnetic wave for canceling an electromagnetic wave transmitted from the power feeding portion. Thus, a magnetic field for canceling a magnetic field formed of the electromagnetic wave transmitted from the power feeding portion is formed, so that overcurrent in the power receiving portion can be prevented.

  • Patent number: 11316359
    Abstract: A power management system can smartly allocate the available power at a location to support more electric vehicles than would otherwise be possible. Power managers can intelligently allocate that power based on the real-time needs of vehicles. A smart energy distribution system can estimate each vehicle's current charge level and use such information to efficiently provide electric vehicle charging. The system can respond dynamically to vehicle charge levels, current readings, and/or electrical mains readings, allocating more current where it is needed. The charger profiles can include historic charge cycle information, which can be analyzed under a set of heuristics to predict future charging needs. A local electric vehicle charging mesh network can be provided, which transmits data packets among short-range transceivers of multiple power managers. The local electric vehicle charging mesh network can be connected to a remote server via a cellular connection.
