An LED based illumination device includes LEDs mounted to an LED mounting board, an integrated output window sub-assembly, and a thermal frame coupled between the integrated output window sub-assembly and the LED mounting board. The integrated output window sub-assembly may include an output window and a thermally conductive ring coupled to the perimeter surface of the output window. The thermally conductive ring may have a radial width equal to or greater than the thickness of the output window. Additionally, the output window and the thermally conductive ring may have coplanar top and bottom surfaces. The thermally conductive ring surrounding the perimeter of the output window may include one or more pockets into which a curable, thermally conductive bonding material is disposed in an uncured state and flows into a gap between the perimeter of the output window and the thermally conductive ring.

A method of producing an assembly for use in a structural element of a fiber-reinforced material includes providing a core element including an inner core and a circumferential cover, the core element having an end part; producing a subassembly by receiving and centering the end part of the core element into a conforming end recess of a bolt fixture; fixing the bolt fixture to the end part of the core element in the subassembly by circumferentially covering the subassembly with a casing formed of cured fiber-reinforced resin; and machining the subassembly circumferentially covered within the casing.

Disclosed herein is a panelboard guard assembly configured to restrict access to a panelboard having a cover and a door defined therein, the cover having first and second side edges. The panelboard guard assembly includes overlapping members that are, at least in some implementations, mutually coupled to each other. The panelboard guard assembly further includes an adjustment mechanism that extends between and couples the members together, the adjustment mechanism facilitating adjustment of the distance between the outer ends of the members.

Systems and methods are disclosed herein for dressing centering a bearing compartment in a gas turbine engine. A nut may be inserted through an outer case of a gas turbine engine. The nut may be coupled to a strut which centers a bearing compartment. The nut may be rotated to achieve a desired tension on the strut to center the bearing compartment. A retaining plate comprising a collar may be positioned over the nut. A swaging tool comprising a swaging ramp may be positioned over the nut. The swaging tool may be forced against the retaining plate using a draw-in bolt. The swaging ramp may contact the collar and form indentations in the collar to lock the nut in place.

A method for sealing surgical instruments, particularly reusable electric surgical instruments sterilized using an autoclave process, includes providing at least two body shells having a runner system on the mating surfaces, aligning the body shells, securing the body shells in position relative to each other, inserting an injection device into the runner system, injecting an elastomer material from the injection device into the runner system, removing the injection device from the runner system, and curing the elastomer material. The elastomer material seals the housing chamber of the instrument. The elastomer material may bond the body shells together.

System and method for mounting one or more photovoltaic modules includes one or more flexible rods, including a first end and a second end opposite the first end, each of the one or more flexible rods further including an inner core and a first jacket surrounding the inner core between the first end and the second end. The first end is configured to be attached to at least one photovoltaic module using one or more first adhesive materials. The second end is configured to be inserted into at least one hole of a modular rail and attached to at least the modular rail using one or more second adhesive materials. The one or more flexible rods are configured to allow at least a lateral movement in a first direction between the photovoltaic module and the modular rail and support at least the photovoltaic module in a second direction.

In an ultrasonic transducer assembly, a conformable ultrasonic transducer has a piezoelectric layer and electrodes able to conform to curved surfaces, and a clamp for pressing the transducer into ultrasonic contact with a curved surface. Conformability is ensured with a thin, porous piezoelectric layer and suitable electrical conductors and insulators. The ultrasonic transducer may operate without further thermal shielding under harsh environments and/or at high temperatures.

A method for sealing surgical instruments, particularly reusable electric surgical instruments sterilized using an autoclave process, is disclosed. The method having the steps of providing at least two body shells having a runner system on the mating surfaces, aligning the body shells, securing the body shells in position relative to each other, inserting an injection device into the runner system, injecting an elastomer material from the injection device into the runner system, removing the injection device from the runner system, and curing the elastomer material. The elastomer material seals the housing chamber of the instrument. The elastomer material may bond the body shells together.

An anchor for lightning protection systems include a base and pad that extend over a sufficient area and a sufficient bearing length to hold in shear and in tension against the weight, shear force, and moment of cables, points, and other components of a lightning protection systems. The mounting anchor is non-penetrating, and adheres to a vertical surface almost immediately without requiring damage to structures, long term support over days waiting for cure, and works in overhang situations as well. An integrated clip may be constructed with the base from sheet material. Adhesion of the base to a cover material on a wall or parapet may be promptly followed by snapping cable into clips formed monolithically with the base.

A cap for use in covering a portion of a fastener protruding from a surface is provided. The portion includes threads. The cap includes an interior, a base that at least partially delimits the interior, a threaded receptacle on the interior configured to threadably engage the portion of the fastener, and a seal coupled to the base to engage the surface.
