Patent number: 9866075Abstract: A system incorporating safety features, for optical power transmission to receivers, comprising an optical resonator having end reflectors and a gain medium, a driver supplying power to the gain medium, and controlling its small signal gain, a beam steering apparatus and a controller to control at least the beam steering apparatus and the driver. 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.Type: GrantFiled: April 11, 2017Date of Patent: January 9, 2018Assignee: WI-CHARGE LTD.Inventors: Alexander Slepoy, Lior Golan, Omer Nahmias, Ran Sagi, Ortal Alpert, Ori Refael Mor

Publication number: 20170358958Abstract: A system for optical wireless power transmission to a power receiving apparatus generally situated in a mobile electronic device. The transmitter has an optical resonator with end reflectors and a gain medium positioned between them, such that an optical beam is generated. The frequency of the beam is selected such that it is absorbed by almost all transparent organic materials in general use. A beam steering unit on the transmitter can direct the beam in any of a plurality of directions, and the beam is absorbed on the receiver by means of an optical-to-electrical power converter, through a low reflection surface. The band gap of this power converter is selected to be smaller than that of the gain medium. The receiver has a voltage converter including an inductor, an energy storage device and a switch. A beam steerer controller ensures that the beam impinges on the receiver.Type: ApplicationFiled: August 7, 2017Publication date: December 14, 2017Inventors: Ori Refael Mor, Ortal Alpert, Alexander Slepoy, Lior Golan, Ran Sagi, Vadim Shmukler, Eitan Ronen, Omer Nahmias, Victor Vaisleib

Publication number: 20170133816Abstract: A distributed resonator laser system using retro-reflecting elements, in which spatially separated retroreflecting elements define respectively a power transmitting and a power receiving unit. The retroreflectors have no point of inversion, so that an incident beam is reflected back along a path essentially coincident with that of the incident beam. This enables the distributed laser to operate with the beams in a co-linear mode, instead of the ring mode described in the prior art. This feature allows the simple inclusion of elements having optical power within the distributed cavity, enabling such functions as focusing/defocusing, increasing the field of view of the system, and changing the Rayleigh length of the beam. The optical system can advantageously be constructed as a pupil imaging system, with the advantage that optical components, such as the gain medium or a photo-voltaic converter, can be positioned at such a pupil without physical limitations.Type: ApplicationFiled: January 20, 2017Publication date: May 11, 2017Inventors: Refael Della-Pergola, Ortal Alpert, Omer Nahmias, Victor Vaisleib
