Designed for OEM integration, Interlink's MicroModule pointing solutions are ideal for computer cursor control in rugged mobile computers, hardened keyboards, navigation systems, machine control panels, and many other computer pointing applications. MicroModule, with its USB interface, can also be easily interfaced to other control applications such as pan and tilt controllers, motion controllers, CNC controllers, and medical control equipment.
MicroModule incorporates Interlink Electronics' VersaPoint® Pressure-Pointing technology. Directional control is achieved by applying pressure in the direction of desired movement. Speed is controlled by altering the amount of applied pressure. The result is smooth cursor movement in any direction, from a precise crawl to a screen-crossing zip. VersaPoint technology has no moving parts to break or wear out, thus delivering reliable, trouble-free cursor control.
The most basic FSR consists of two membranes separated by a thin air gap. The air gap is maintained by a spacer around the edges and by the rigidity of the two membranes. One of the membranes has two sets of fingers which are interdigitated and electrically distinct; each set connects to one trace on the tail. The other membrane is coated with FSR ink. When the two layers are pressed together, the FSR ink shorts the two traces together with a resistance that depends on applied force.
