Abstract: 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.

Abstract: New systems for the wireless recharging of the batteries of game controllers, without the need for placing the game controller on a dedicated charging device such as an inductively coupled charging pad or its charging docking station. Wireless charging can continue even when the gaming controllers are being moved, when in use during the gaming session, and certainly when the controller is left by the user in some random location in the area in which the system is installed. A transmitter beams optical power, such as a laser beam, to an optical power receiver located on the controller itself, which, using a photovoltaic cell and an appropriate voltage converter, converts the optical beam power to a current for charging the battery. A beam aiming mechanism, such as a scanning mirror, is provided to ensure correct tracking of the game controller, according to the outputs of a beam tracking application.
