Abstract: An apparatus for selectively adjusting the angle of inclination of a work surface, such as a desk top, comprising a casing attached to the bottom side of one end of the work surface, with a foot device comprising a circular cylindrical part with positioning channels in the periphery thereof and a foot member extending therefrom and with the cylindrical part contained within the casing, an engaging member projecting in the inside of the casing and for locking selected ones of the channels, and resilient member for holding the cylindrical part against the engaging member, whereby manual rotation of the foot member to different locking positions of the channels and engaging member, enables adjustment of the length and angle of extension of the foot member outside of the casing, and thus determine the space between the work surface and a base, with the other end of the work surface being pivotally connected.

Abstract: A capacitive switching device having a pair of stationary electrodes, a movable electrode disposed capacitively relative to the stationary electrodes, and an actuator carrying the movable electrode and including a resilient member biasing the actuator away from the stationary electrodes. The movable electrode comprises a sponge member having non-porous layers on opposite sides thereof, and a resilient conductive layer adhering to one of the non-porous layers. The other non-porous layer is secured to the actuator such that the resilient conductive layer faces the stationary electrodes. A process of manufacturing the device is also disclosed.
