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 fluid control device includes a vibrating plate unit, a driver, a flexible plate, and a base plate. The vibrating plate unit includes a vibrating plate including first and second main surfaces, and a frame plate surrounding the surrounding of the vibrating plate. The driver is bonded to the first or the second main surface of the vibrating plate and vibrates the vibrating plate. The flexible plate includes a hole provided therein, and is bonded to the frame plate so as to face the vibrating plate. The base plate is bonded to the main surface of the flexible plate on a side opposite to the vibrating plate. A size relationship between the coefficients of linear expansion of the material of the base plate and the frame plate is equal to a size relationship between the coefficients of linear expansion of the material of the vibrating plate and the driver.

The invention takes into account the antenna bandwidth, filtering characteristics and low-profile AiP structure, the bandwidth covers a plurality of 5G millimeter wave frequency bands, the filtering is realized through the upper and lower sideband radiation zeros, and the magnetic dipole and the feeder are mixed and connected with the metal strip through the metallized vias to achieve the low-profile design effect.

A hand band sander (10) with a housing (11) that contains a drive (15) for the sanding band (18) comprising a motor (16) with gear (17), which sanding band (18) can be driven in circulating fashion by way of a drive pulley (19) that can be driven in rotary fashion, and preferably by way of a return pulley (20), is smaller, easier to handle, and more reasonably priced due to the fact that the drive pulley (19) is arranged and supported coaxially to the drive (15) and is driven directly by the output of the gear (17).

A two-port isolator includes a first center electrode and a second center electrode which are wound around a ferrite to which a direct-current magnetic field is applied from permanent magnets, and the ferrite is mounted on a circuit board having built-in matching circuit devices. The ferrite is preferably substantially rectangular-parallelepiped-shaped having first and second principal surfaces that are substantially parallel to each other, and the long-side length of the principal surfaces is about 1.5 to about 5 times the short-side length. The second center electrode is wound between one and four turns around the ferrite.

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.

The present disclosure is directed to a window screen system for use with casement, hopper, awning, utility window designs to prevent dirt, debris, and insects from entering into the interior of the unit. The system can be installed on existing window frames to provide screen protection only when the window is open and a screen is needed. As such, a user can have a clear view out of the glass window without the unsightliness, distortion, or solar blockage that a traditional “always visible” screen causes.
