Abstract: A handpiece for treatment of the surface of a target tissue with at least one light beam is provided, the handpiece including a housing, at least one light source for generating at least one light beam, an opening for allowing the emission of the at least one light beam out of the housing and towards the target surface, a mechanism for controlled displacement of the at least one light source to move the at least one light beam across the target surface; and a controller for controlling the mechanism. A method is provided for treating a tissue surface with a light beam that includes directing a light beam towards the tissue surface, focusing the light beam at the tissue surface so that the focal point is positioned proximate the surface of the tissue so that the diameter of the light beam is smaller at the surface of the tissue than below the surface.

Abstract: A device for measurement and signal generation having multiple different test and measurement applications and an application selector to choose which application is currently active, the device having a graphical screen selector and an input mechanism to enable application selection. The applications use a graphical display of measurement data or input parameters, and each application uses available measurement hardware for different measurement functions to reduce the need for several individual measurement devices. Various test and measurement applications are provided for any specific type of measurement or signal generation. They will typically measure or generate signals in various test and measurement domains, such as high precision multi-meter type measurements, industrial control, signal generator application, audio, communication, device characterization, data logging, etc.
