摘要： 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.

摘要： 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.

摘要： 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.

摘要： A power beaming system includes a power beam transmitter arranged to transmit the power beam, and a power beam receiver arranged to receive the power beam from the power beam transmitter. A power beam transmission source is arranged to generate a laser light beam for transmission by the power beam transmitter from a first location toward a remote second location. A beam-shaping element shapes the laser light beam, at least one diffusion element uniformly distributes light of the shaped laser light beam, and a projection element illuminates a power beam receiving element of predetermined shape with the shaped laser light beam. At the power beam receiver, a diffusion surface diffuses a portion the power beam specularly reflected from the power beam receiver.
