The sensor head and the rotatable drum may be disposed within a vacuum chamber.

Abstract: A standoff connection structure which is suitable for connecting a standoff connector and a high-voltage electronic box. The standoff connection structure includes at least one anti-rotation feature, and also includes various sealing features to provide a leak-tight connection between a standoff connector and high voltage electronic box, even after exposure to thermal shock. The standoff connector also facilitates an electrical connection between a high voltage or high current component and the high voltage electronic box.

Abstract: An electronics unit includes a housing, the housing having a base portion with a post member extending from the base portion. The post member has a through-hole defined through the post member. A printed circuit board is connected to the housing at a plurality of connection points. The printed circuit board includes one or more electric or electronic components disposed thereon and has an aperture. The post member is disposed through the aperture of the printed circuit board. A distal end portion of the post member is larger than a diameter of the aperture so as to fix the printed circuit board to the housing, forming one of the connection points. A seal member is disposed at least partly within the through-hole of the post member and forms a seal with the post member.

Abstract: An electronics device includes a housing having a through-hole disposed in a central portion of the housing. A printed circuit board is connected to the housing. The printed circuit board includes one or more electronic components disposed thereon. A plastic housing cover is connected to the housing and covers the printed circuit board. The housing cover includes a centrally-located post member integral to the housing. The post member extends through the through-hole of the housing and engages with the housing. The engagement between the housing and the housing cover prevents outward deflection of the housing cover.

Abstract: An electronics device is disclosed, including: a first printed circuit board having a plurality of through-holes; a second printed circuit board having a plurality of through-holes; a housing in which the first and second printed circuit boards are disposed, the first printed circuit board disposed above the second printed circuit board in the housing; and a connector attached to the housing and including a plurality of pins comprising first pins and a plurality of second pins, a length of the first pins being greater than a length of the second pins. Each of the first pins extends through one of the through-holes of the first printed circuit board and one of the through-holes of the second printed circuit board and thereby makes an electrical connection with the first and second printed circuit boards, and each of the second pins only extends through one of the through-holes of the second printed circuit board and thereby makes an electrical connection with the second printed circuit board.

Abstract: An engine control unit (ECU) includes a housing; a cover sealingly engaged with the housing so as to define an interior space; a circuit board disposed in the interior space; and a fastener coupling together the circuit board, the housing and the cover, the fastener serving to limit an amount of deflection of the housing relative to the housing. The circuit board and the cover are constructed and arranged to define an airflow path from an outer surface of the cover to the interior space. The airflow path allows for a leak test to be performed on the ECU, wherein upon an affirmative determination that results of the leak test shows no leaks in the ECU, sealant seals the airflow path.
