Disclosed are interposer electrical connector embodiments including magnetic components used to facilitate interconnection of peripheral devices to standard input / output, or “I / O”, connectors (such as USB connectors) of devices such as mobile communications products (e.g. smart phones, tablets, and personal computers). The interposer connector embodiments disclosed include those in which a plurality of discrete permanent magnets are arranged with magnetic poles aligned in the same orientation perpendicular to and on one side of the electrical interface. Other embodiments include a plurality of bar permanent magnets located on opposite sides of the interface with all poles of the same type directed at the interface, but each one opposing a ferromagnetic element. These arrangements provide self-aligning capabilities useful for electrical connections that have restrictions on visibility or connection approach geometries. Other embodiments have a single magnet per mated connector pair and magnetic pole pieces and / or actuators to concentrate magnetic flux providing the magnetic attractive force for a plurality of electrical connections.

There is disclosed an improved fuel door assembly. In one preferred embodiment, the fuel door comprises a housing that defines an axis of rotation and has a biasing element that is at least partially surrounded by a second interface that forms a cavity that narrows between the ends of the second interface. The fuel door has a first interface that contacts the second interface such that the biasing element urges the fuel door toward the closed position when the fuel door is at the closed position, and urges the fuel door toward the open position when the fuel door is at the open position.

A wave-fan comprises a wavy surface, generally sinusoidal in the direction of rotation, which rotates in close proximity to the fins of a heat sink. The wave-plane fan is suitable for use with a flat heat sink, and a wave-ring fan is suitable for use with a cylindrical heat sink. There are no airfoils as in a prior art fan. Instead, the ridges of the wave-fan agitate the air between the fins of the heat sink as each ridge passes, breaking down the boundary layer and effecting good heat flow into the air. In some embodiments of the wave-fan, the outer surfaces are smooth, so it is not a hazard to intruding fingers, so in many applications it may be used without a guard or enclosure. Incidental centrifugal force provides some airflow through the fan to transport the heated air away from the fan. Also, the configuration of the fan tends to keep contamination in the air out of the heat sink fins, so an inlet air filter may not be needed. Because the net airflow through the fan is low, less power is required and it is very quiet.

A wheel rotation device assists in cleaning, inspection and maintenance of wheels. The device has a ramp, a backstop, and two contoured rollers, fastened to rails. The device operates upon a flat surface such as a garage floor or driveway, and avoids slipping from friction with the flat surface and a non-skid treatment on to the underside of the rails. The ramp allows the motorcycle to be rolled forward onto the rollers that centers the motorcycle wheel upon and between the rollers as it is manually rotated. The backstop limits forward movement of the motorcycle wheel to within the rear of the device. The rear roller, nearest the backstop, has spindles projecting through the rails and have machined ends that accept a tool to rotate the motorcycle wheel.

An inventive traction device is provided for extricating mired vehicles from mud, snow or sand. The device is comprised of modules linked together to create a track upon which a mired vehicle drives over. The individual modules each have four walls forming a trough and a number of tire supports which rise up from the floor of the trough. The trough-like construction of the device helps prevent the device from becoming overloaded with mud deposited from mired vehicle tires.

A device to restrain a prisoner has a nylon strap attached to a spring-loaded spool, which the operator attaches by means of a clasp to the prisoner's handcuffs or restraining apparatus, and the nylon strap automatically retracts through the seat into the spool's housing located behind the seat as the prisoner sits down. When the prisoner is seated against the seatback, the law enforcement officer activates a remote-control locking switch, which causes a 12-volt braking mechanism to engage and prevent the nylon strap from being pulled out, which holds the prisoner securely in place against the seat and prevents him / her from being able to move enough to release a seatbelt or unlock and open a vehicle door. When the officer is ready to remove the prisoner, he / she again activates the remote-controlled switch which releases the brake and allows the nylon strap to be extracted while the prisoner steps away from the seat.
