Abstract: The present invention provides a power assisted cover actuator for operating a tonneau cover for an open bed of a truck, such as a pickup truck. The cover is hingably coupled to a distal end of the truck bed adjacent the truck cab. The power assisted cover actuator in accordance with an embodiment of the present invention comprises a track upon which a trolley is guided by a linear actuator. An end of an arm is pivotally coupled to the trolley and the cover. The linear actuator comprises a motor driven drive rod coupled to the trolley that extends to advance the trolley along the track from a lower position to a higher position which raises the arm to push the cover open. Retracting the drive rod reverses the direction of travel of the trolley from a higher position to a lower position lowering the arm and closing the cover.

Abstract: A modular contact switch adapted to be readily assembled from a plurality of contact modules is provided. Both active contact modules and passive contact modules comprise coupling features, including but not limited to, engagement tabs and mating surfaces, to enable a removable coupling of multiple active contact modules to form active contact assemblies and passive contact modules of a passive contact assembly. The active contact modules provide a spring-biased contact that responds to the position of passive contacts of the passive contact modules. As the active and passive contact modules come into abutment and urging engagement, an electrical connection is made between the corresponding contacts. The spring-bias of the active contacts ensures that the electrical contact is made regardless of variations in tolerances and position.

Abstract: Apparatus and methods are provided to enable the removal of tablet and capsule medication from bottles. The apparatus includes a bottle opener assembly that enables the removal of the medication from the base of the bottle. Removal of the medication from the base of the bottle bypasses the need for removal of the bottle cap, tamper-resistant seals, and any filler material. The present invention further includes an automated unpack/repack system for packing the medication in bulk and individual containers.

Abstract: The present invention provides a door opening assist device comprising a spring-biased piston having a threaded bore mounted in a cylindrical housing by a threaded bolt. The piston retains a spring within the housing at a first end of the housing. The threaded bolt engages the piston from a second end of the housing. The piston is retained within the housing by the cooperative engagement between the spring urging the piston out of the first end and the head of the bolt in abutment with the second end. The door opening assist device is installed in a door frame of an automobile to push the door open a predetermined distance. The door opening assist device provides various mounting options. Upon closing the door, the door abuts and retracts the piston into the housing compressing the spring. Upon unlatching the door, the piston extends under spring bias in such a direction and with sufficient force to push the door to an open position a predetermined distance.
