US Patent:

41896610, Feb 19, 1980

Filed:

Nov 13, 1978

Appl. No.:

5/959823

Inventors:

Paul O. Haugsjaa - Acton MA
Edward F. White - Dorchester MA

Assignee:

GTE Laboratories Incorporated - Waltham MA

International Classification:

H05B 4124
H01J 6504

US Classification:

315 39

Abstract:

An electrodeless fluorescent light source has an electrodeless lamp mounted in a termination fixture which includes an inner conductor and an outer conductor disposed around the inner conductor and is coupled to a high frequency power source. Power is coupled to an ultraviolet-producing low pressure discharge in the electrodeless lamp which acts as a termination load within the termination fixture. A phosphor coating on the inner surface of the electrodeless lamp emits visible light upon excitation by ultraviolet radiation. Alternatively, the phosphor coating can be on the inner surface of a transparent envelope which forms part of the termination fixture. In this case, the phosphor coated envelope can be removable from the light source. The light source can be dimmed by reducing the microwave power input. Frequency of operation is typically from 902 MHz to 928 MHz.

Abstract:

A method of processing a liquid material. The method includes mixing a liquid material with a solvent, wherein the solvent has a constituent capable of coating the particles of the material. The liquid material mixed with the solvent is then particlized, deposited on a substrate and activated to form a pre-defined electrically conductive pattern. Particlization methods include sonication and the deposition methods include ink-jet printing. Activation methods include applying mechanical pressure. The method can be used to produce electronic devices. The electronic devices made by the method include strain gauges. The substrates utilized for making the electronic devices utilizing the method can be wearable or stretchable or both.
