摘要： An optical module for interconnecting two or more optical fibers has a microreplicated waveguide element which is integrally formed on the same substrate with a splice element. In one embodiment, the module has three plates, a bottom plate, a cover plate, and a top plate, all contained within a common housing. The bottom plate has fiber-receiving grooves and fiber alignment grooves at its ends, the fiber alignment grooves being aligned with waveguide channels formed on the central portion of the bottom plate. The cover plate is used when forming the cores of the waveguide channels, to force residual curable, waveguide material into flow channels adjacent the waveguide channels, and this material, when cured, adheres the bottom and cover plates together. The top plate is used to clamp fibers which are held in the fiber alignment grooves, with the center of the fibers aligned with the core of the waveguide channels. The module housing includes wedges which may be independently actuated to secure the fibers, in a remateable fashion, to either end of the module.

摘要： A device for splicing multiple optical fibers includes a novel splice element having two plates formed from a sheet of malleable material, there being a fold line in the sheet forming a hinge, the two plates being folded toward one another to define opposing surfaces. One of the opposing surfaces has several fiber receiving grooves therein, parallel with the fold line, and the other surface has ramps at each end to support the fibers proximate the transition from their buffered portions to their stripped portions. The ramps are adjacent porches which are integrally formed with one of the plates, the porches having additional grooves for aligning the fibers with the fiber receiving grooves. Stop pads are provided on both opposing surfaces, at the corners of the plates, to insure a clearance space at the ends of the plates which provides for more gradual clamping of the fibers, reducing insertion loss.

摘要： A device for interconnecting the bare ends of two or more optical fibers uses a common receptacle having a fiber clamping element therein and camming surfaces for actuating the element, and at least one plug having a camming finger for engaging one of the camming surfaces. The camming surfaces are located such that, when only one of the camming surfaces is actuated, the clamping element rocks to a side of the pocket opposite the one camming surface and remains in the open state, but when both of the camming surfaces are actuated, the clamping element is forced to the closed state. The plug includes a fiber protector free to slide within the plug housing, substantially enclosing the bare end of the fiber when the plug housing is removed from the receptacle, but retracting when the plug housing is inserted into the receptacle to direct the bare end of the fiber toward said guide tube. A fiber collet biases the terminal end of the fiber toward the forward end of the plug place a preload condition on the bare end of the fiber. The connector is particularly suited for cleave-and-bevel installations. The receptacle preferably uses a novel clamping element having two plate members with fiber-contacting surfaces, at least one of said fiber-contacting surfaces having a fiber-receiving groove. Edges of the plates are aligned and held together with a split tube spring. At least one of the plate members is provided with a wire-receiving groove and a wire therein which acts as a fulcrum to allow the plates to pivot along an axis defined by the wire. The split tube spring provides a precisely controlled load along the edges of the plates, allowing the opposite ends to be clamped together (within the guide tube) by a force sufficient to overcome the controlled load of the split tube spring.

摘要： An optical fiber splice element comprising a sheet of ductile material having a novel focus hinge defining first and second legs, each of the legs having a V-groove therein for receiving the optical fibers. The focus hinge, comprising a groove on one side of the sheet, a notch on the other side of the sheet aligned with the groove, and a convex hinge web, provides precise registration of the V-grooves when the sheet is folded; this in turn leads to improved alignment of the fibers. The V-grooves also have a novel angular geometry which optimizes the clamping forces, resulting in lower insertion loss. The interior angle of the V-grooves is smaller than the optimum angle whereby, when the fiber is clamped and portions of the V-groove surfaces are deformed, the V-groove has an effective angle which is approximately equal to the optimum angle.

摘要： A lift apparatus has a frame with open sides and a web assembly slidably retained along the sides which extends from one end of the frame to the other. While the web assembly is retracted, the frame moves to pass around a mobility-impaired individual and rest against the surface supporting the individual. The web assembly is then extended to move underneath or behind the individual, providing lifting support. The frame is configurable for orientations ranging continuously between horizontal and upright sitting. The web assembly has an upper web contacting the individual, a lower web contacting the support surface, a strength layer carrying the individual's weight, and a roller nose bar assembly which is pulled to extend the web assembly. A hand-held power tool can drive the web assembly, adjustment of inclinations of the back and leg sections of the frame, and vertical motion of the lift arm.

摘要： A table assembly for a patient transfer device has an upper table with side plates that are differentially extended at the ends, and valve control for pneumatic tubing integrated with retraction of the side plates. During patient delivery only the delivery side plate is raised, to avoid catching linens in the nip formed between upper and lower belts. A slide assembly supporting the table assembly includes a fixed plate, an intermediate plate, and a full-motion plate which extend by means of rack-and-pinion drives. Each plate is symmetrical, and pinions are symmetrically located on opposite sides of the fixed or intermediate plate to allow hyperextension to either the left or right. Improved steerage for the device is provided by two centerline wheels which counter-rotate from a straight position to a turning position and further to a lateral position wherein the wheels are orthogonal to the longitudinal centerline of the device.

摘要： A patient transfer device has four casters and two counter-rotating steering wheels. The steering wheels provide a turning path whose center of curvature lies along a transverse centerline of the device. A foot pedal selectively lifts the steering wheels off the floor or brakes them. Another foot pedal at a back end of the device can lock the casters at the front end in a straight direction. The transfer table of the device may be inclined either longitudinally or transversely, and has an upper table whose edge rollers retract to introduce slack in the upper belt so that an air mattress can be inflated. The upper belt selectively disengages from the lower belt using movable, pneumatically-actuated pinch rollers. The outer surface of the upper belt is rough while the outer surface of the lower belt is smooth. The belts are constructed of a material which includes an antimicrobial agent.

摘要： A derailleur utilizes a 4-bar linkage, including a housing which acts as one bar of the 4-bar linkage. A hydraulic assembly located within the housing moves the housing relative to the mounting shaft in response to hydraulic pressure to define a chain guide operating path. The derailleur device may include a detent mechanism formed on one of the three other bars. In one embodiment, the 4-bar linkage includes an input shaft rotatably attached to the housing at a one end, and an output shaft rotatably attached to the housing at the other end, and the housing rotates around the first shaft in response to the actuation force. The hydraulic assembly may include a piston which moves within a cylindrical bore, with one of the three other bars of the 4-bar linkage being attached to the piston. The resulting hydraulic derailleur design is comparable to mechanical (cable-pull type) derailleurs in size and weight.
