Device and a Method for Powering Laser Projectors

Abstract

An arrangement and a method are provided, wherein the arrangement is configured to prevent current pulses from reaching a laser diode, wherein the arrangement is configured to receive voltage required for its operation from a USB power source, and wherein the arrangement comprises: a capacitor configured to provide energy for the operation of the laser diode at times when high current pulses are required by a camera associated with the arrangement; a software configurable micro controller, operative to control functionality of the arrangement so as to prevent current pulses from reaching the laser diode; and a current source configured to provide current for the operation of the laser diode under safe conditions and to cease provisioning of that current when conditions are unsafe for the operation of the laser diode.

Dependencies are inferred from the claim text.
