A full duplex, low latency, near field data link controls a resonant induction, wireless power transfer system for recharging batteries. In an electric vehicle embodiment, an assembly is aligned with respect to a ground assembly to receive a charging signal. The vehicle assembly includes one or more charging coils and a first full duplex inductively coupled data communication system that communicates with a ground assembly including one or more charging coils and a second full duplex inductively coupled data communications system. The charging coils of the ground assembly and the vehicle assembly are selectively enabled based on geometric positioning of the vehicle assembly relative to the ground assembly for charging. As appropriate, the transmit/receive system of the ground assembly and/or the vehicle assembly are adjusted to be of the same type to enable communication of charging management and control data between the ground assembly and the vehicle assembly during charging.

Near field, full duplex data link for resonant induction wireless charging

A vehicle alignment system is adapted to align a vehicle with a wireless power induction coil for wireless charging through use of magnetic resonant induction. The system includes a transmission line disposed in the parking slot so as to guide the vehicle to the wireless power induction coil for charging. The transmission line leaks a signal having an operating frequency that is detected to align the vehicle left-right in the parking slot when the vehicle is aligned for charging by the wireless power induction coil. At least two vehicle mounted antennas mounted on opposite sides of transmission line when the vehicle is aligned in the parking slot detect the operating frequency from the transmission line, and signal processing circuitry detects a relative signal phase between signals detected by the antennas that is representative of alignment of the vehicle with respect to the wireless power induction coil and the parking slot.

Method and apparatus for the alignment of vehicles prior to wireless charging

A full duplex, low latency, near field data link controls a resonant induction, wireless power transfer system for recharging batteries. In an electric vehicle embodiment, an assembly is aligned with respect to a ground assembly to receive a charging signal. The vehicle assembly includes one or more charging coils and a first full duplex inductively coupled data communication system that communicates with a ground assembly including one or more charging coils and a second fill duplex inductively coupled data communications system. The charging coils of the ground assembly and the vehicle assembly are selectively enabled based on geometric positioning of the vehicle assembly relative to the ground assembly for charging. As appropriate, the transmit/receive system of the ground assembly and/or the vehicle assembly are adjusted to be of the same type to enable communication of charging management and control data between the ground assembly and the vehicle assembly during charging.

In a network-based Wireless Location System (WLS), geographically distributed Location Measurement Units (LMUs) must be able to detect and use reverse channel (mobile to network) signals across multiple BTS coverage areas. By using Matched Replica correlation processing with the local and reference signals subdivided into discrete segments prior to correlation, the effects of mobile clock drift and Doppler shifts can be mitigated allowing for increased processing gain. By using historical network and real-time data about the radio signal and/or radio channel, the segmentation and computation scheme may be optimized to reduce latency and enhance capacity while maximizing location accuracy.
