Abstract: Systems and methods for maritime infrasound detection can include at least one waterborne platform. A microbarometer, inertial measurement unit (IMU) and heave cancellation component (HCC) can be mounted on the waterborne platform. The HCC can receive a pressure input from the microbarometer and the IMU to generate an output pressure that can be indicative of an infrasound signal of interest (SOI). The HCC can further include a filter and an adaptive algorithm. The filter can receive IMU pressure and environment noise pressure as inputs. An error signal from the HCC output can also be supplied through a closed feedback loop that includes a Recursive Least Squares adaptive algorithm, which can further include a weighted, tapped delay line. The system can further include a remote data center for receiving the HCC output from the waterborne platform(s), which can be buoys, vessel or USV's.

Abstract: An access system for a structure includes a control box mounted within a controlled access space of the structure and operatively coupled to a door panel operator that opens and closes a door panel of the structure for access to the controlled access space.

Abstract: An anti-rotation guide for a lifter in an overhead valve valvetrain. The anti-rotation guide includes a plug having two lobes connected through a neck region. A first lobe of the plug is held within a bore in the lifter. The bore forms an opening at the edge of the lifter through which the neck of the plug emerges. The bore in the lifter accommodates a first lobe of the plug that is wider than the opening in the edge of the lifter, whereby the plug is shaped to prevent its slipping from the lifter through the opening. The lifter reciprocates in a first bore in the cylinder head. The second lobe of the plug extends outward from the lifter into a second bore formed in the cylinder head and adjoining the first bore. The second lobe reciprocates in the second bore and limits rotation of the lifter.

Abstract: An electrical connector includes a housing having an upper wall and a first protrusion and a CPA element slidably coupled to the housing along the upper wall between an extended position and an inserted position. The CPA element includes a base and a first beam extending from the base having a first arm and a first finger including an abutment wall configured to abut against the first protrusion and a tip configured to be engaged by a mating connector when received in the housing. The tip is deflected from a blocked position to a released position with the distal end engaging the protrusion in the blocked position and the tip being deflected outside of the protrusion to the released position where the tip is able to clear past the protrusion to allow the CPA element to be moved from the extended position to the inserted position. The CPA may be configured so that in the extended position it is to block release of a pivotal latch used to retain the connector to a mating connector.
