Abstract: Embodiments are directed towards a safety system that can be used with a high-flux power beam, such as in wireless power transmission. The system includes a transmitter that generates and transmits a power beam and a receiver that receives the power beam. A plurality of sensors is configured to independently detect if an object is near, impeding, or about to impede (i.e., impinging) the power beam. Each of the plurality of sensors is configured to detect the object at different distances between the transmitter and the receiver. A controller triggers the transmitter to stop generating the power beam when any one or more of the plurality of sensors detects the object or a combination of the plurality of sensors detects the object. The controller triggers the transmitter to re-generate and transmit the power beam when each of the plurality of sensors fails to detect the object.

Abstract: A commercially available vehicle is modified by coupling a beamed-power transmission system to the vehicle's frame. The beamed-power transmission system is arranged to deliver beamed power to a remote device such as an unmanned aerial vehicle (i.e., UAV or drone). The cooling system of the vehicle is used to cool portions of the beamed-power transmission system. An aiming system aims a power beam produced by the beamed-power transmitter toward the remote device, and a stability system coupled to both the vehicle frame and the beamed-power transmission system maintains three-dimensional constancy of the power beam even when the vehicle frame is in motion. The commercially available vehicle may be an electric vehicle, a gas-electric hybrid vehicle, or the like having a power source that includes batteries, a fuel-cells, or a generator.

Abstract: A power beaming system includes a power beam transmission unit (102) to generate and transmit a high-flux power beam (106) toward a receiving unit (108) at a remote location. The receiving unit includes a photovoltaic array (128) having a defined perimeter shape, and the power beam transmission unit includes at least one vertical cavity surface emitting laser (VCSEL) array (150), which has a plurality of VCSEL emitters (152). The power beam transmission unit also includes a projection lens apparatus (126) and a control system. The control system which comprises a controller (136C) is arranged to control a light output of the VCSEL array (150), which includes controllably enabling a selected portion of the plurality of VCSEL emitters corresponding to the defined perimeter shape of the photovoltaic array, and controllably diffusing light with a diffuser (130) from the VCSEL array to uniformly illuminate a projection surface of the projection lens apparatus.

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.

Abstract: Various embodiments provide a laser power beaming system that delivers power via high intensity light, such as from a laser, using either power over fiber or free space power to isolate (or eliminate) high frequency noise and electromagnetic interference (EMI) due to, for example, switching. Damage or other harms from the EMI may be prevented. The opto-isolated power may be delivered from a remote source, or within a switched device, such as a variable frequency drive (VFD), itself.

Abstract: Embodiments are directed towards a multi-stage wireless power transmission system that includes a transmitting unit and a receiving unit. The transmitting unit transmits a power beam to the receiving unit, which converts the power beam into local electrical power and provides it to a personal electronic device without a corded connection between the receiving unit and a mains power supply. The transmitting unit includes a light-based transmitter to generate and transmit a power beam towards the receiving unit. The receiving unit includes a receiver to receive at least a portion of the power beam and to convert the received power beam into local electrical power. The receiving unit also includes a power output unit to provide the received local power to a personal electronic device when the personal electronic device, which is separable from the receiving unit, is electrically coupled to the power output unit.
