Abstract: The present invention is directed to a micro-switch assembly involving a magnetic latching mechanism. In one aspect of the present invention, it involves a micromachined structure that comprises an outer frame, an inner frame pivotally connected to the outer frame and rotates when an external electromagnetic force is applied, and a mechanism for latching the inner frame at a given angle of inclination relative to the outer frame. One embodiment of the present invention involves the use of a magnetic material, such as Permalloy, and permanent magnets to achieve the latching result. A Permalloy piece is attached to the inner frame of the micro-switch assembly and a magnet layer is attached to the outer frame. The magnetic force attracting the Permalloy piece and the magnet layer allows the latching of the two frames to occur in the absence of the external applied electromagnetic force.

Abstract: An apparatus for positioning an optical component, such as a lens or reflector. Positioning of the optical component is facilitated by an adaptive support that is coupled to the optical component on one end, and secured to a generally static structure at an opposing end. The adaptive support comprises a flexible support member on which a plurality of piezoelectric elements are mounted. In response to differential voltages applied to selected piezoelectric elements, localized portions of the flexible support member are caused to extend or contract. As a result, this localized extension and contraction alters the configuration of the adaptive support such that the orientation and/or position of the optical component are changed.

Abstract: An electric contact plug receives a tip jack input at a plug-in zone, and completes the electrical connection via a connection zone to an electronic component, such as a printed circuit board. The electric contact plug also includes an intermediate zone, connected between the plug-in zone and the connection zone. The intermediate zone is designed to deform mechanically when the plug-in zone is subjected to vibrational stresses, as typically occur in a motor vehicle. As a result, the tip jack is held securely within the plug-in zone, while the intermediate zone absorbs the effects of the vibrational stresses. Thus, the inventive electric contact plug avoids the problems of friction and corrosion within the plug-in zone. Moreover, this electric contact plug is compatible with thick-wire bonding, and can be manufactured economically.

Abstract: A method for securing a glass fiber to a housing includes positioning the glass fiber in proximity to the wall of a housing and applying a quantity of solder glass frit to the surface of the glass fiber. Sufficient solder glass frit is employed so as to occupy the gap between the glass fiber and the housing. The solder glass frit has a melting point lower than that of the glass fiber. The surface of the glass fiber is not metallized. Upon heating the solder glass frit softens and adheres to both the glass fiber and the wall of the housing. The fused solder glass frit secures the glass fiber to the housing and forms an hermetic seal therebetween.
