Abstract: An engine control module having an environmentally-sealed housing includes a housing-mounted air pressure sensor for providing a reliable measure of atmospheric air pressure to a control circuit mounted within the housing. The sensor is mounted on an inboard face of the housing, and includes a sensor element, a body portion and a riser portion. The sensor element is mounted in the body portion, and the riser portion protrudes through an opening in the housing to couple the sensor element to atmospheric pressure outside the housing. The body portion is sealingly secured to the inboard face of the housing, and a set of conductor pins molded into the body portion extend inward to engage a circuit board enclosed by the housing, and thereby directly couple the sensor element to the ECM's control circuit. The top of the riser portion is capped by a splash-proof lid to prevent water intrusion.

Abstract: Power electronic devices of an electronic control module are mounted in a power module disposed between the control module circuit board and an interior face of the control module case, with a prescribed separation distance between the circuit board and a housing of the power module. The power electronic devices are mounted on an inboard face of a power module substrate, and a heatsink thermally coupled to the opposite face of the substrate is fastened to an interior surface of the control module case. The substrate and heatsink are mounted in the power module housing, and the power electronic devices are electrically coupled to the circuit board by a set of compliant terminals that protrude from the inboard face of the power module housing. The terminals extend into plated holes in the circuit board, and have shoulders that limit their depth of insertion to establish the prescribed separation distance between the circuit board and the power module housing.

Abstract: A surface mount multi-axis cavity package for micro-electrical mechanical systems (MEMS) devices includes a substantially cubical housing having a plurality of sides and at least one internal cavity. A first plurality of solder pads are positioned on at least one side of the housing and a second plurality of solder pads are positioned on a bottom of the housing. A MEMS sensor is then mounted within the at least one internal cavity in any axis for increasing the versatility of the MEMS device.

Abstract: A fastening structure for an antenna module assembly is disclosed. The fastening structure for an assembly includes a cover, a gasket inner seal, a circuit board including at least one antenna element, and a base. The gasket inner seal is placed over the circuit board. The gasket inner seal and circuit board are intermediately located between the cover and the base. The base includes a plurality of beveled snap-tab receiving portions integrally located about a base perimeter. The beveled snap-tab receiving portions engage an inner perimeter of the cover defined by flexible snap-tabs to fasten and matingly secure the cover to the base.

Abstract: A material-handling machine includes a substantially horizontal girder having an end, a supporting flanged wheel at the end, a truck having rail-riding wheels on a rail and a girder mid-portion extending from the end and connected to a support leg extending between the mid-portion and the truck. The leg and the mid-portion are connected by a pin permitting relative movement between the mid-portion and the leg. Such pinned connection reduces wear of the rail and the rail-riding wheels and reduces bending stress in the support leg.
