A system for use in covering a portion of a fastener protruding from a surface is provided. The system includes a cap that includes an interior, a base that at least partially delimits the interior, and pawls on the interior. The system may also include a tooth configured to be associated with the fastener and configured to positively engage the pawls.

The invention is a motorized gearbox assembly. The motorized gearbox assembly includes a motor that drives an output shaft. The output shaft actuates a window covering by applying torque to a tilt rod of the window covering. The output shaft extends substantially an entire length of the motorized gearbox assembly. It also has a through-channel that extends substantially an entire length of the output shaft, so that the tilt rod can pass entirely through the motorized gearbox assembly. Because of this, the motorized gearbox assembly can be used for retrofitting blinds. In some embodiments, the motorized gearbox assembly has a diametrically polarized magnet driven by the output shaft, and a position encoder that measures the output shaft's position and number of rotations.

A clamping apparatus secures a photovoltaic module to a rail. The clamping apparatus includes a bolt extending between a first end and a second end of the bolt. The clamping apparatus includes a clamp defining a bolt opening into which the bolt is received and a support structure. The support structure positions the clamp at a first location on the bolt. The first location is a first distance from a top rail surface plane within which a top surface of the rail lies. The support structure is adjustable to position the clamp at a second location on the bolt. The second location is a second distance from the top rail surface plane. The first distance is different than the second distance. The support structure has a support structure thickness corresponding to a third distance that is less than the first distance and less than the second distance.

A linkage system for transmitting torque includes a central element, an input arm and an output arm. The central element has four sides and a top and bottom. The input arm and an output arm each have a head portion for connecting with the central element and a body portion. The head portion of each of the input and output arms defines a bearing surface having a first radius. The input and output arms engage the central element such that the bearing surfaces of the heads are offset by 90 degrees.

A magnetic bracket includes a base and at least two posts at opposite ends of the base. The posts bend upwards from the base such that at least two clips are operable to attach at the posts at opposite ends of the base. The posts have a notch between the base and ends of the posts to permit the clips to hook onto the posts. The magnetic bracket may be clipped into a vehicle chassis by removably inserting the clips into a slot of the vehicle chassis. A body panel such as a headliner having a magnetic fastener attached to the body panel may then be magnetically self-aligned and removably attached to the base having a magnetic portion. The magnetic fastener is operable to be removably attached to the magnetic portion. The magnetic bracket is attached to a non-magnetic part of a vehicle chassis.

Provided is an expanding rivet connection for the connection of at least two components to be joined comprising an expanding rivet, comprising an expanding rivet body, which is shaped so that it can be inserted through openings into the first component to be joined, and a threaded part, which is shaped so that it protrudes, at least in part, after insertion from the first component to be joined, an expanding rivet mandrel, which is constructed so that it can be pushed through an opening in the expanding rivet into the expanding rivet body in order to protrude through the first component to be joined, and a clamping element, which is constructed to be screwed to the threaded part of the expanding rivet in order to connect at least a third component to be joined to the first component to be joined.

A cage with a fastening system (1) in a magnetic resonance device (MRD) is disclosed, said cage in an MRD comprising (a) M pole pieces (45) (M2); (b) N side magnets (20) (N2), said side magnets substantially enclosing said pole pieces and thereby defining a magnetic envelope and enclosed volume therein; (c) N side walls (10), said side walls substantially enclosing said side magnets; (d) P face walls (30) (P2); and (e) a plurality of fastening rods (100); wherein each of said fastening rods physically interconnects at least one pair of side walls, passing through at least one of said side magnets and at least one of said pole pieces.

A motorized window covering switching mechanism is described herein. The switching mechanism includes a deflectable arm and a pull cord. The deflectable arm is connected to a first contact, and the pull cord is connected to the deflectable arm such that, as the pull cord is tugged, the deflectable arm deflects to move the first contact toward a second contact, thereby converting gestures of the pull cord into electrical signals that control a motorized window covering. In some embodiments, cord gestures that deflect the deflectable arm include pull sequences, numbers of pulls, strength of pulls, or combinations thereof. Additionally, in some embodiments, a controller receives the cord gestures and translates the cord gestures into operational commands to control and operate a window covering gearbox assembly.

A kit for illuminating chain slots on a trailer includes a plurality of brackets, each having a first arm and a second arm. The second arm is oriented at an angle to the first arm and has a mounting area. A tool is provided for positioning a bracket adjacent a respective chain slot on the trailer and for holding the bracket in place adjacent the chain slot until the bracket is attached to the trailer. The tool has a portion configured to engage with the mounting area of the bracket. Lights are also provided, each light configured to be attached to a respective mounting area of the bracket after the bracket has been attached to the trailer and the portion of the tool has been disengaged from the mounting area. An electrical conductor is configured to connect the plurality of lights to an electrical wiring harness of the trailer.

A system for use in limiting axial movement between a hanger and a fairing assembly within a turbine assembly is provided. The hanger includes an inner radial hanger bend portion that defines a hook channel therein. The fairing assembly includes an outer surface, a hook member extending from the outer surface to mate with the hook channel, and a circumferential groove defined in the outer surface such that at least a portion of the hanger bend portion is positioned between the circumferential groove and the hook member. The system includes a retention member sized for insertion into the circumferential groove, wherein the retention member is configured to extend from the circumferential groove and press against the hanger bend portion to facilitate maintaining the hook member within the hook channel.
