摘要： A data transfer method for autonomous vehicles includes autonomously positioning a vehicle to achieve an alignment condition in which a vehicle-mounted directional antenna coupled to a vehicle radio is aligned with a curbside antenna coupled to a curbside radio. A peer-tip-peer radio link is established between the vehicle radio and the curbside radio, and data is transferred from the vehicle radio to the curbside radio using the peer-to-peer radio link. The peer-to-peer radio link may be a millimeter-wave radio link. Data is transferred at high speed, for example at least tens of gigabits per second or even hundreds of gigabits per second. The vehicle may be an electric vehicle, and electric charging of the vehicle may be performed while transferring the data. In one embodiment, the vehicle is configured to proceed to a recharging location when a given low state of charge is reached. Transferring data may be performed at a rate such that during recharging from the low state of charge to a target state of charge, all data to be transferred from the vehicle is transferred, or at least a terabyte of data is transferred.

摘要： High efficiency DC to RF conversion with use of active harmonic insertion is provided for power amplification over a wide dynamic range of input signal level. Specifically, a power amplifier device including at least a final amplification stage is operated to receive an input signal of a fundamental frequency. A drive signal is produced which includes a fundamental signal component of the fundamental frequency and at least one harmonic signal component of a harmonic frequency that is substantially an integer multiple of the fundamental frequency, wherein relative phase shift and relative amplitude of the components are controlled over at least an order of magnitude of dynamic range of the input signal. As the signal level of the input signal decreases (or increases), the desired proportion of signal levels is maintained between the components. The drive signal is provided to the power amplifier device, and in response to the drive signal, an amplified output signal is produced at the final amplification stage.
