Abstract: An apparatus and method of manufacturing a crystal grower is disclosed. The crystal grower includes a reservoir constructed to receive a crystal growing material therein. An induction heater having a coil of woven stands of wire is disposed proximate the reservoir and heats the crystal growing material.

Abstract: A traffic control system utilizes geometric or mathematical designs and/or secondary lights for traffic signals so as to allow red/green color blind individuals to determine whether the signal is for stop or go.

Abstract: A method and system for system for welding a workpiece is disclosed. The workpiece is preheated while the weld is being performed. The preheating is performed fast enough that it can be done on-the fly- immediately in advance of the weld. The preheating is preferably accomplished with an induction heating system. The induction coil is mounted with the welding torch such that as the torch is moved along the weld path, the coil precedes it, preheating the weld path.

Abstract: An electronic circuit (100) for reducing electromagnetic interference includes a plurality of circuit elements (130, 140, 150) to which a set of bussed logic signals (343) generated by a set of first circuits (342) is distributed by a logic clock (120). The electronic circuit (100) further includes a plurality of cascaded busses (355, 135, 335) including a last cascaded bus (335) having a last enablement phase. Each of the plurality of cascaded busses (355, 135, 335) couples a set of amplified logic signals (355, 135, 335) from one of the plurality of circuit elements (358, 359, 336) to another one of the plurality of circuit elements (359, 336, 322). The set of amplified logic signals (355, 135, 335) of each of the plurality of cascaded busses is enabled during an enable period (351, 352, 330) which lasts beyond an end of the last enablement phase.
