Abstract: A push stop (100) for use in a slot disposed in a worksurface includes: a body (102), a resilient element (104), and an anchor assembly (106). The anchor assembly is configured to anchor a first portion (110) of the body in a fixed anchored position within the slot. A resilient force exerted by the resilient element urges a second portion (114) of the body into a fixed raised position in which the second portion protrudes beyond the worksurface.

Abstract: An apparatus (100), including: a hub (102) having a hub center (160); a securing mechanism (106) configured to fix the hub onto a flat surface; and an eccentric clamp disk (104). When the hub is fixed to the flat surface and nested in the eccentric clamp disk, an interlocking slip fit relationship exists between the hub and the eccentric clamp disk. The interlocking slip fit relationship enables infinite rotation of the eccentric clamp disk about the hub center and has a geometric interlock (170). The geometric interlock is configured so that when the eccentric clamp disk is pushed laterally into contact with the hub, the geometric interlock urges the eccentric clamp disk downward onto the flat surface.

Abstract: A layer stack including a first bonding dielectric material layer, a dielectric metal oxide layer, and a second bonding dielectric material layer is formed over a top surface of a substrate including a substrate semiconductor layer.

Abstract: An in-line clamp (100), including: a base (200) having a bottom (202) that defines a bottom plane (204) and a ramp feature (210); and a pusher (300) having a cooperating feature (304) and a contact ridge (314) disposed opposite the cooperating feature. Movement of the cooperating feature along the ramp feature moves the contact ridge downward toward the bottom plane and away from the base in a clamping direction (510). The clamping direction forms an acute clamping direction angle (514) with the bottom plane. An adjustment mechanism (500) is configured to apply a push force (322) on the pusher to move the contact ridge in the clamping direction. The push force is applied in a push force direction (322D) that forms an acute push force direction angle (508) with the bottom plane. The acute clamping direction angle is different than the acute push force direction angle.
