Abstract:

An energy emitting system includes a housing with a controller, scanner and non-interruptible interface, having a bandwidth of at least 20 KHz and a latency of not more than 5 milliseconds, disposed therein. An interface port receives input at the housing. The controller issues command control signals, including trajectory control signals, corresponding to the received input. The non-interruptible interface interconnects the controller and the scanner, and communicates the issued trajectory control signals from the controller to the scanner. The scanner directs a continuous movement of energy simultaneously in two directions, in accordance with the communicated trajectory control signals.
