Seal It, Protect It!
A Smalley Laminar Seal is a metallic labyrinth seal consisting of multiple rings in a groove. Sealing an assembly from contamination while withstanding high temperatures and corrosive environments, Laminar rings are produced from metal. The arrangement and orientation of the rings are dictated by the application/severity of the environment.

New PolyVent compact vent for automotive housings

With its new GORE PolyVent Compact Series, W. L. Gore & Associates provides higher performance venting in a smaller footprint for automotive electronic housings. About 30 percent smaller than the widely used PolyVent Snap-Fit product family, the new GORE PolyVent Compact Series is easier to integrate into even the smallest housings. It provides a higher level of protection for sensitive components like sensors, motors, and control units, while providing reliable and rapid pressure equalization.

Posi-drive belts and sprockets for precision belt-drive applications

Sterling Instrument provides single- and double-core posi-drive belts and sprockets for applications that require accurate positioning. The no-slip design offers several distinct advantages. No flanges are required, which saves space and also prevents the trapping of air between the belt and the flanges, creating a much quieter operation. The system also operates with no backlash, which is essential for applications that require no lost motion. Single-core belts and sprockets can be used in applications where the shafts are oriented at an angle with one another. The central core, made of either aramid fiber or stainless steel, can twist in such a way that the pins still stay in perfect mesh with the sprocket. This allows the shafts on either sprocket to be oriented at a full 90-degree angle without sacrificing belt performance. The belts are made of molded polyurethane and require no lubrication. They have excellent chemical and abrasion resistance, making them suitable for medical and food-processing applications. They are sold either by pin count or by the foot up to 100 ft.

High-precision rotary stage

Steinmeyer has announced a new addition to its line of precision rotary stages. The standard DT130-DC stage is a worm gear-driven unit with a rotary encoder and features positional accuracy of +/- 0.07 deg, repeatability of +/- 0.007 deg, a max speed of 15 rpm, and a load capacity of 50 Newton. Drive mechanism is a DC servo-motor. This stage is ideal for applications such as laser machining, precision wafer inspection, photonics, fiber optics, and cell diagnostics. The DT130-DC can also be equipped with a direct reading encoder attached to the rotating stage for higher positioning accuracy. Stage body is manufactured from a low-distortion aluminum alloy (black anodized) and includes a high-stiffness bearing set. This rotary stage is designed to easily mate with Steinmeyer's MT130 linear stage.

Disney researchers develop algorithm for rendering 3D tactile features on touch surfaces
By altering the friction encountered as a person's fingertip glides across a touchscreen surface, a new algorithm by Disney Research, Pittsburgh, can create a perception of a 3D bump on a touch surface without having to physically move the surface. The method can be used to simulate the feel of a wide variety of objects and textures. The algorithm is based on a discovery that when a person slides a finger over a real physical bump, the person perceives the bump largely because lateral friction forces stretch and compress skin on the sliding finger. The Disney researchers used electrovibration to modulate the friction between the sliding finger and the touch surface with electrostatic forces. The algorithm dynamically modulates the frictional forces on a sliding finger so that they match the tactile properties of the visual content displayed on the touch screen along the finger's path.
