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.

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 power beaming system includes a power beam reception unit and a power beam transmission unit. The power beam reception unit includes a power conversion array, such as a photovoltaic array, arranged to capture at least a portion of a power beam, and a power supply circuit arranged to convert flux from the captured portion of the power beam to electric power. The power beam transmission unit includes a power beam transmitter circuit to transmit a low-flux search beam during a first time window, and further arranged to transmit a high-flux power beam during a second time window. The power beam transmission unit also includes a location detection circuit arranged to identify a location of the reception unit based on the power beam transmitter circuit transmitting the low-flux search beam during the first time window.
