Abstract: A power beaming system delivers electric power in laser light from a first location to a remote second location. The laser light has a high energy intensity level defining a hazardous illumination area and a low energy intensity level defining a safe illumination area. The system includes guard circuitry emitter(s) and corresponding detector(s). The guard circuitry forms a detection area about the hazardous illumination area to detect objects in proximity to the hazardous illumination area. A controller directs the guard and power beam circuitry according to sequentially activated safety modes to operate at a low energy intensity level, to scan in a defined pattern, to adjust operation of the detector(s), and to set guard circuitry parameters based on a time value, an object detection value, or a change to the delivered electric power. An output coupled to the controller and power beam circuitry controllably permits or prevents operation at the high energy intensity level.

The controller responds to a safety risk occurring in the system, by outputting a command to change at least some of the small signal gain of the gain medium, the radiance of the optical beam, the power supplied by the driver, the scan speed or the scan direction and position of the beam steering apparatus, or to register the scan pose which defines the location of said optical-to-electrical power converter. The controller may also ensure a high overall radiance efficiency, and may warn of transmitted power not received by a targeted receiver.

Abstract: Pulsed power loads (PPLs) are highly non-linear and can cause significant stability and power quality issues in an electrical microgrid. According to the present invention, many of these issues can be mitigated by an Energy Storage System (ESS) that offsets the PPL. The ESS can maintain a constant bus voltage and decouple the generation sources from the PPL. For example, the ESS specifications can be obtained with an ideal, band-limited hybrid battery and flywheel system.

First and second detection methods, based on different detection schemes, may be used to detect and distinguish the presence of foreign matter from misalignment during power transfer operation. A first detection method may be used before power is transferred to a load in a power reception apparatus, and a second detection method may be used while power is supplied to the load.

Abstract: A method and system for contraband detection is provided that allows for the determining whether devices are authorized to receive power from an outlet. A power adapter and/or an outlet authenticate a device when it is connected to the outlet through the power adapter. On the basis of this authentication, a determination is made whether the devices are to receive power from the outlet. If the device is authorized, the outlet is activated, transitioning from inactive state (where no power is relayed through the outlet) to an active state (where power is relayed through the outlet).

Abstract: A motion-enable device includes a mechanical switch and a capacitive sensor with a sensing region that is located adjacent to the mechanical switch. The mechanical switch enables a first signal when closed or actuated that indicates that the mechanical switch is in an active state. The capacitive sensor enables a second signal when a conductive object is disposed in the sensing region, where the second signal indicates that the capacitive sensor is in an active state. Enablement of operation of an apparatus depends on receipt of both the first signal and the second signal. The mechanical switch and the capacitive sensor act as the two separate switches required by functional safety requirements for a motion enable device. Because the sensing region of the capacitive sensor is adjacent to the mechanical switch, the first and second signals are generated when an operator actuates the mechanical switch with a single digit.

Abstract: Systems and methods for leveraging multipath wireless transmissions for high data rate communication and charging devices within multipath vehicle environments are described. The techniques include deploying a wireless charger, including an array of antennas, within a vehicle interior. The wireless charger may detect an incoming signal from a client device. Each antenna in the array may determine an offset for the received signal, which is then used to tune parameters for each antenna individually. Upon transmission, the resulting signal is directionally biased toward the least lossy pathways between the device and the charger. These pathways avoid passengers and other sources of signal attenuation. Thus, for a given total power envelope, a greater total signal amplitude may be delivered to the device, with reduced exposure to any occupants of the vehicle. Additionally, the interior of the vehicle may be provisioned to help improve multipath focusing of transmissions.
