Virtual reality GTAW and pipe welding simulator and setup

A simulator facilitating virtual welding activity. The simulator may include a logic processor based subsystem operable to generate an interactive welding environment in virtual reality space that emulates welding activity by simulating a virtual weld puddle having dynamic, real time molten metal fluidity and heat dissipation characteristics, responsive to performing a simulated welding activity in real time. The simulator may include a foot pedal device in operative communication with the logic processor based subsystem and configured to affect a characteristic of the virtual weld puddle in real time, responsive to user control of the foot pedal device. The simulator may be configured to track the movements of a mock welding tool and a mock filler wire and determine interaction between the virtual weld puddle, a corresponding virtual welding tool, and a corresponding filler wire in virtual reality space that would result in the welding tool becoming contaminated.

Micro-electro-mechanical switch, and methods of making and using it

A micro-electro-mechanical (MEMS) switch (10, 110) has an electrode (22, 122) covered by a dielectric layer (23, 123), and has a flexible conductive membrane (31, 131) which moves between positions spaced from and engaging the dielectric layer. At least one of the membrane and dielectric layer has a textured surface (138) that engages the other thereof in the actuated position. The textured surface reduces the area of physical contact through which electric charge from the membrane can tunnel into and become trapped within the dielectric layer. This reduces the amount of trapped charge that could act to latch the membrane in its actuated position, which in turn effects a significant increase in the operational lifetime of the switch.

Capacitive dome switch

This is directed to a dome switch that includes a capacitive sensor. A dome switch can include a dome operative to deform to provide tactile feedback to a user. To provide an electrical instruction to the device, the region underneath the dome can define a free space separating conductive regions forming a capacitor. For example, a tip of the dome, a button placed between the dome and a circuit board, or a user's finger can form a first conductor of a capacitor, and a support structure for the dome can include a terminal forming a second conductor completing the capacitor. When the dome deflects, the distance between the conductors can change and provide a measurable capacitance variation, which the device can detect. To protect the dome switch from damage due to contaminants, the terminal can be integrated within a volume of the circuit board such that it is not exposed to the environment of the dome switch. In one implementation, the terminal may not be exposed to air.

Touch panel and method for manufacturing the same

The present invention relates to a resistive-film type touch panel using a transparent conductive polymer film as a transparent electrode film. The touch panel includes a transparent resin sheet and a glass substrate having an ITO film formed thereon. After a solution having a transparent conductive polymer dispersed in a solvent is applied to the undersurface of the transparent resin sheet, the solution is heated and dried in order to form a transparent conductive polymer film. The ITO film and transparent conductive polymer film serve as transparent electrode films that are opposed to each other. When the transparent resin sheet is pressed, the films touch each other. Consequently, a change in resistance corresponding to the pressed position can be detected.

The spring has a radial member protruding through the pattern of the housing. A plunger is mounted in the opening along the axial direction, abutting the spring for urging the spring in the axial direction and for moving the member in the pattern along the perimeter. After a pre-determined number of activations of the plunger in the axial direction, the member will come to a terminating position and will either contact a pin to establish electrical continuity or at the terminating position break electrical continuity.

Stacked metal and elastomeric dome for key switch

A low travel keyboard and methods of fabrication are described. The low-travel keyboard is suitable for a thin-profile computing device, such as a laptop computer, netbook computer, desktop computer, etc. The keyboard includes a key cap positioned over stacked elastomeric and metal domes. The quick force drop of the metal dome provides the crisp “snappy” feel for the user and the elastomeric dome provides the ability for longer travel than the metal dome alone. The metal dome also activates the switch circuitry of the membrane on printed circuit board. The stacking of the elastomeric metal domes takes advantage of the abrupt force drop in the metal dome buckling and applies it to the elastomeric dome force, making it possible to design a low-travel key while still maintaining or improving the tactile feeling of the key switch.
