Abstract: The present invention relates to a truck topper supporting table device for removing and storing a truck topper from a pickup truck. The truck topper table enables a single individual to easily remove and install the topper on their own, and avoids the topper from having to be placed onto the ground when it is not on the truck. The truck topper table has two pairs of scissor-style collapsible legs that can be adjusted to a desired height. The table has a pair of horizontal rails positioned on the collapsible legs with rollers disposed along the length of the rails for easily rolling off the topper of the truck and onto the table. The table has cross members for increasing strength of the table to withstand heavy truck toppers.

Abstract: According to one or more aspects, a health sense system for a pulse width modulation (PWM) device associated with a magnetic coil is provided, and includes a health sense circuit, a health logic circuit, and a counter circuit. The health sense circuit measures one or more current measurements at a low voltage side of the pulse width modulation device. The health logic circuit determines a health bit indicative of a health score for the magnetic coil of the pulse width modulation device based on one or more of the current measurements. The counter circuit generates a feedback command for the pulse width modulation device based on the health bit.

Abstract: A modular auxiliary switch includes a housing including a first housing part and a separate second housing part secured to the first housing part. A printed circuit board is housed in one of the first and second housing parts, and has a first side facing the first housing part and a second opposite side facing the second housing part. An actuator mechanism is housed in the first housing part and is coupled to the printed circuit board. A separate first electrical contactor is selectively mounted to the printed circuit board so that a first electrical contact surface of the first electrical contactor overlaps and is in direct contact with one of the first side and the second side to define a first electrical contact pad on the printed circuit board.

Abstract: An auxiliary switch includes a housing including a first housing part and a second housing part separate from and releasably connected to the first housing part. A printed circuit board is fixedly mounted within the housing and has an electrical pad and an electrical contact connected to the electrical pad. A terminal conductor is electrically connected to the printed circuit board. An actuator mechanism is mounted within the housing and has an electrical contactor engaged to the terminal conductor. The actuator mechanism is configured to move within the housing and at least partially displace the electrical contact while maintaining engagement between the contactor and the terminal conductor.

Abstract: Active power factor correction can be used to reduce input harmonics in an aircraft power distribution system. In an embodiment, one or more power factor correction (PFC) units can be placed in a power distribution system to profile an input signal. Each PFC unit can include a converter, such as an AC-DC converter, and can be placed in the power system bus on the input side of the load. In an embodiment, a PFC unit can include a boost rectifier topology with active power factor correction for harmonics elimination.
