  • Publication number: 20210084251
    Abstract: Examples described herein include systems, devices, and methods for backscattering carrier signals in accordance with pixel values of an image and/or video. Signals having a property proportionate to pixel values may be converted into a pulse-containing waveform having pulses whose widths and/or duty cycles are determined based on the pixel values. Backscatter transmitters may backscatter a carrier signal in accordance with the pulse-containing waveform to provide the pixel values to a receiver. In this manner, video transmission at low power and/or battery-free operation may be provided.

  • Patent number: 10812130
    Abstract: Examples of backscatter systems, device, and techniques are described herein. Example backscatter devices may utilize CSS modulation to provide backscatter signals including CSS signals (e.g., LoRa packets). Utilizing CSS modulation may advantageously allow for backscatter communication over wide areas. Examples of backscatter devices described herein may toggle the impedance of the backscatter device between multiple (e.g., eight) impedances to reduce and/or eliminate higher order harmonic components in the backscatter signal (e.g., third and fifth harmonic components).

  • Publication number: 20200091768
    Abstract: A wireless power transfer system includes a transmitter configured to transmit power to a receiver, for example, through coupled resonators. The transmitter receives feedback from the receiver, and uses the feedback to control the power transmission, to control a parameter at the receiver, for example, a rectified voltage output by the receiver. The feedback to the transmitter may be provided, for example, by an out-of-band radio system between the transmitter and receiver, by a reflection coefficient at the transmitter, and/or by an encoded modulation of power in the receiver, for example, in an impedance matching module. The transmitter may control the transmitted power, for example, by controlling a transmitter signal generator voltage (VSiG), a transmitter gate driver voltage (VGD), a transmitter amplifier voltage (VPA), and/or an impedance setting in a transmitter impedance matching module.

  • Patent number: 10587445
    Abstract: Apparatuses, systems, ambient RF backscatter transceivers, and methods for communicating using MIMO and spread spectrum coding of backscattered ambient RF signals are described. An example system may include an ambient RF backscatter transceiver that include an antenna configured to receive a backscattered ambient radio frequency (RF) signal, and a receiver coupled to the antenna. The receiver may be configured to demodulate the backscattered ambient RF signal using one of multiple input, multiple output multiplexing demodulation or spread spectrum code demodulation to retrieve the first data. The backscattered ambient RF signal may be generated by backscattering an ambient RF signal at a first frequency. The ambient RF signal may be configured to provide other data at a second frequency.
