    Abstract: The method includes receiving axis signals from a multi-axis position sensing detector, generating a reference signal by summing the axis signals, determining a mirror position of a mirror directing the optical beam based on the beam position error of each axis of the multi-axis position sensing detector, and actuating the mirror to move to the mirror position. Each axis signal is indicative of a beam position of an optical beam incident on the multi-axis position sensing detector, each axis signal corresponding to an axis of the multi-axis position sensing detector. For each axis of the multi-axis position sensing detector, the method includes converting a phase of an axis to have a 90 degree phase difference from a signal of the axis, generating an axis-phasor signal by summing the axis signals, and comparing the axis-phasor signal and the reference signal to determine a phase difference.

    Abstract: A transmitter includes a first resonator to generate an oscillating field at a resonant frequency in response to receiving power from a power source. The transmitter includes a first communication interface and a first controller to control the first resonator and to communicate data via the first communication interface. One of a plurality of receivers includes a second resonator to be wirelessly coupled to the first resonator. The second resonator resonates at the common mode resonant frequency in response to the oscillating field. The one receiver includes a second communication interface to establish wireless side-channel communications with the first communication interface and to communicate the data with the first communication interface via the wireless side-channel communications. The first controller identifies the one receiver from the plurality of receivers according to the communicated data, and in response, the first resonator transfers the power to the second resonator.

    Abstract: Embodiments described herein may help to provide medical support via a fleet of unmanned aerial vehicles (UAVs). An illustrative UAV may include a housing, a payload, a line-deployment mechanism coupled to the housing and a line, and a payload-release mechanism that couples the line to the payload, wherein the payload-release mechanism is configured to release the payload from the line. The UAV may further include a control system configured to determine that the UAV is located at or near a delivery location and responsively: operate the line-deployment mechanism according to a variable deployment-rate profile to lower the payload to or near to the ground, determine that the payload is touching or is within a threshold distance from the ground, and responsively operate the payload-release mechanism to release the payload from the line.
