Abstract: A method for printing electrically conductive traces on a non-conductive material includes: printing a conductive material onto a non-conductive material by transferring ultrasonic energy to the conductive material; forming non-conductive resin on the non-conductive material on which the conductive material has been printed, using a three-dimensional printer head, the non-conductive resin being (or serving as) an insulation component, or placing a prepreg on the non-conductive material on which the conductive material has been printed; and forming a connecting portion or via hole in the non-conductive resin or the prepreg.

Abstract: A system for scalable multiple-material additive manufacturing (SMAM) includes: an on-demand multiple material manufacturing (M3) unit configured to additively print a designed object, the M3 unit comprising a multi-functional ensemble head configured for multiple material printing, in-line metrology, in-line error corrective milling, and in-line quality inspection; a process control unit configured to autonomously control all functions of the system with remote operation interfaces; an expandable post-processing unit configured to perform heat treatment and polishing/deburring, following the printing; an environmental control unit including an oxygen removal system and particulate filters for additive manufacturing and post-processing; a protective housing providing structural stability and vibration isolation with power and electrical interfaces; a printing head assembly comprising a plurality of printing heads with a multiple feeding mechanism; a laser scanning metrology to monitor dimension discrepancy wi

Abstract: A lighting device includes a housing; a plurality of light emitting diodes (LEDs) located on a first side of the housing; a plurality of switches for controlling the plurality of LEDs; and a controller operably coupled with the plurality of switches and configured to control operations of the plurality of LEDs in response to inputs received via the plurality of switches. Each of the plurality of switches is exposed through a corresponding hole formed at the housing, and a top surface of each of the plurality of switches is lower than a surface of the housing through which the plurality switches are exposed.

Abstract: A reduced emissions work light composed of a two module system for easy assembly and reassembly of component parts. The first module includes a bulb, a ballast, a ballast housing, an end cap, a socket fixture, and an electrical cable. A socket fixture is configured to secure a connection between the ballast housing and the bulb to create a single unitary body. The first module is placed inside a second module to form the reduced emissions work light containing only two separate components.
