Described herein are techniques related to a haptic keyboard that features a satisfying tactile keypress experience. Using active tactile feedback (i.e., haptics) via its keys, one or more of the described example keyboards simulates the feel of a snap-over keypress of conventional keys, such as that of a rubber-dome keyboard. With its haptics, one or more of the described example keyboards feel like—through the user's fingers on keycaps—keys having the non-linear force/displacement characteristics of the snap-over of conventional keys.

MEMS switches and methods of fabricating MEMS switches. The switch has a vertically oriented deflection electrode having a conductive layer supported by a supporting layer, at least one drive electrode, and a stationary electrode. An actuation voltage applied to the drive electrode causes the deflection electrode to be deflect laterally and contact the stationary electrode, which closes the switch. The deflection electrode is restored to a vertical position when the actuation voltage is removed, thereby opening the switch. The method of fabricating the MEMS switch includes depositing a conductive layer on mandrels to define vertical electrodes and then releasing the deflection electrode by removing the mandrel and layer end sections.

High thermal stability pellet compositions for thermal cutoff devices and methods for making and use thereof

Номер: US20130334471A1
Автор: Changcai ZHAO, Katherine HINRICHS
Принадлежит: Therm O Disc Inc

The present disclosure provides a pellet composition having enhanced thermal stability for use in a thermally-actuated, current cutoff device. Certain inorganic stability additive particles, such as silica, talc, and siloxane, can be mixed with one or more organic compounds to form a thermal pellet composition. A solid thermal pellet maintains its structural rigidity up to a transition temperature (T f ), but further has improved overshoot temperature ranges. Therefore, the improved thermal pellets have a maximum dielectric capability temperature (T cap ), above which the pellet composition may lose substantial dielectric properties and conducts current that is at least 50° C. greater than the T f . In certain variations, maximum dielectric capability temperature (T cap ) is greater than or equal to about 380° C.
