Abstract: A MEMS acceleration detection device including a housing having a cavity and a spring mass system assembled into the cavity of the housing. A lid enclosing the spring mass system in the cavity and contacting a top surface of the housing.

Abstract: A housing, for surface-mount technology (SMT), accepts any electronics package that is mounted on a circular substrate. The housing including the assembled electronics package forms an SMT housing assembly. The SMT housing assembly is placed directly onto the surface of a printed circuit board (PCB). The SMT housing assembly is soldered to the PCB using standard soldering techniques, establishing an electrical connection between the electronics package and the PCB.

Abstract: The present invention provides a housing for surface-mount technology (SMT). In particular, the housing accepts any electronics package that is mounted on a circular substrate. The housing including the assembled electronics package forms an SMT housing assembly. The SMT housing assembly is placed directly onto the surface of a printed circuit board (PCB). The SMT housing assembly is soldered to the PCB using standard soldering techniques, establishing an electrical connection between the electronics package and the PCB.

Abstract: A spring contact, an inertia switch, and a method of manufacturing an inertia switch are provided. The spring contact includes a conductive body portion having an outer edge and an inner edge partially surrounding an open area, a split in the conductive body portion, the split extending between the outer edge and the inner edge, and a conductive contact finger extending from the inner edge into the open area. The inertia switch includes a shell; a mass movably positioned within the shell; the spring contact positioned within the mass; a biasing member positioned between the spring contact and the header; and a conductive member extending through the header. The biasing member provides a bias between the spring contact within the mass and the conductive member. The method includes at least partially closing the split in the spring contact during insertion of the spring contact within the mass.
