Patent number: 11923694Abstract: 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.Type: GrantFiled: June 7, 2022Date of Patent: March 5, 2024Assignee: LASERMOTIVE, INC.Inventors: Thomas J.

Patent number: 11867868Abstract: The plurality of emitters and the plurality of detectors form a light curtain that is patterned about the beam, and are positioned to surround the beam. The plurality of emitters each have a centerline and each have a divergence angle centered on the centerline. The placement and orientation of the plurality of emitters about the acceptance centerline of the beam receiver are configured to align the centerlines of the plurality of emitters substantially parallel to the incoming beam. The detection of one or more of the plurality of emitters by one or more of the plurality of detectors depends on the divergence angles of each of the plurality of emitters and the tilt of the beam receiver relative to the beam centerline.Type: GrantFiled: January 21, 2022Date of Patent: January 9, 2024Assignee: LaserMotive, Inc.Inventors: Thomas Sayles, Thomas W.

Publication number: 20230155690Abstract: A reflector assembly at a power beam receiver includes at least two sets of reflection surfaces positioned to shift some incoming light away from the center of the beam and towards the periphery. These surfaces may be positioned obliquely to one another, for example orthogonally. By shifting a portion of the power beam away from a higher-intensity center and toward a lower-intensity periphery, the reflector assembly may improve receiver efficiency without substantial redirection of power outside of a power-collecting surface of the receiver.Type: ApplicationFiled: November 11, 2022Publication date: May 18, 2023Inventors: Sergiy DETS, Thomas J.

Publication number: 20220113444Abstract: 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.Type: ApplicationFiled: December 17, 2021Publication date: April 14, 2022Applicant: LaserMotive, Inc.Inventors: Jordin T.
