Abstract: A captive fastener and method of use is disclosed wherein the screw is comprised of a head and shank, and where the shank includes a radial counter bore that retains a spring biased pin. The spring may bear against a plug in the counter bore or the shank inner wall, and biases the pin outward such that it extends outside of the shank in the absence of a compressive force. The captive screw is inserted through a top panel by tilting the screw at the opening of the panel such that the pin is pushed inward into the channel formed by the counter bore (against the force of the spring). Once the pin is recessed in the screw, the screw is passed through the panel opening until the shank emerges on the other side. Once the shank pushes through the panel, the pin will emerge under the biasing of the spring to extend outward of the shank in the radial direction. The pin thus prevents the screw from disengaging with the panel.

In some examples, the print particle replenishment device includes an output assembly to output print particles, comprising an interfacing portion. In some examples, the print particle replenishment device includes a plurality of contact pads disposed on an outer portion of the output assembly to rotate with the output assembly when opening a channel of the print particle replenishment device.

Abstract: In some examples, an apparatus can include a mating interface coupled to a dispense interface to interact with a print particle dispense nozzle, a locking mechanism coupled to the dispense interface to prevent the print particle dispense nozzle from depositing a print particle to the dispense interface, and an authentication mechanism coupled to the locking mechanism to: authenticate the print particle dispense nozzle, and unlock the locking mechanism when the print particle dispense nozzle is authenticated to allow the print particle dispense nozzle to deposit the print particle to the dispense interface.

Abstract: Examples of a host device that includes an input recess are described. In some examples, the input recess includes a rotating port cover offset from a central axis of the input recess. In some examples, the input recess includes a plurality of contacts disposed on an interfacing surface of the input recess to interface with a print particle replenishment device when the rotating port cover is rotated. In some examples, the plurality of contacts interfaces with a control device to authenticate the print particle replenishment device.

Abstract: In some examples, an apparatus can include an outer syringe body including a normally open switch and a pushrod and a plunger including a tab, where the tab of the plunger is adapted to be in contact with the pushrod when the plunger is moved from a first position into the apparatus to a second position to cause the pushrod to close the normally open switch.

Abstract: A captive fastener is disclosed having a longitudinal slot along the shank for receiving a hold out clip, and a pair of diametrically opposed slots for receiving a pair of push out clips. The push out clips are formed with hook shaped ends that catch and engage an edge of a wall surface to set the distance of depth of the fastener inside the wall. The hold out clip and push out clips are shaped to receded inside their respective slots in the presence of an interfering surface as the fastener passes through the wall in a first direction (insertion), but the push out clips will not recede into their slots in the second direction (withdrawal).

Abstract: A captive fastener is disclosed having a longitudinal slot along the shank for receiving a hold-out clip, and a chamber that houses a retractable cam member. The cam member is spring actuated to extend out of the shank and can be retracted into the cavity against the bias of the spring to pass through a primary panel and subpanel. The cam member is shaped to counter-rotate in the presence of a traverse force, such as the panel bearing against it.

Abstract: A captive fastener comprising a head, a neck, and a threaded shaft, and one or more spring loaded pins disposed within respective cavities of the shaft along at least first and second radial directions. Each spring loaded pin is located in a chamber of the shaft with an annular rim on at a proximal end of the pin that prevents the pin completely passing through an aperture and out the chamber. The distal end of the pin projects through the aperture and out of the shaft when the spring is not compressed. That is, the spring biases the pin outward such that a distal portion of the pin projects through the hole, but the spring can collapse to allow the fastener to pass through a fitted opening sized to receive the shaft of the fastener before the pin expands outward.

Abstract: A headgear securement system including a first support at a first portion of the headgear, a second support, separate from the first support, at a second portion of the headgear, a closure connected to the second support to lock the second support at a selected one of a plurality of fit settings and a compliance mechanism connected to the second support.

Abstract: Systems and methods for writing, changing, authenticating and signing web-based documents use an interactive questionnaire methodology and various databases to obtain document content, confirmation of the finality of a proposed document and participant identity verification. Multiple databases may be accessed and/or created to triangulate or otherwise confirm that a purported party to be bound by a legal instrument is the same party adding information to the document and that all parties to be bound by a contract have signed the same final version of the contract. Disclosed embodiments allow participants to change the terms of a proposed agreement that has been signed by others. A modified proposed agreement may be signed by the amending party and then offered to all interested parties.

Abstract: Eyewear can be provided which includes a frame and at least one earstem that can be removably coupled to the frame. The frame and/or the earstem can include a retention assembly and/or an engagement structure. For example, the earstem can include at least one prong extending from an anterior end thereof and a latch component that can collectively engage an engagement structure of the frame.

Abstract: Various embodiments of an eyeglass and eyeglass system are provided that can maintain the geometric and optical quality of a lens supported by the eyeglass. The eyeglass can comprise a frame, a support member carried by the frame, and a lens mounting area or groove extending at least partially along at least one of the frame and the support member. The support member can be pivoted, moved, or deflected relative to the frame between a retaining position and an open position. In the open position, the lens can be seated within the lens mounting area. In the retaining position, the support member and the frame retain the lens without exerting deformative forces on the lens. Accordingly, the as-molded geometric and optical qualities of the lens can be preserved.

Abstract: Eyewear, such as a goggle, is provided that can include an anterior module (such as a lens support) and an interchangeable posterior module (such as a faceplate). The anterior module can be adapted to support at least one lens in a wearer's field of view. The posterior module can be adapted to fit against a contour of the wearer's face and can be selectively interchangeable with the anterior module to modify at least one physical characteristic of the eyewear. In some embodiments, the anterior and posterior modules can be coupled by a suspension assembly in order to allow articulation of the posterior module relative to the anterior module for evenly distributing forces against the wearer's face. Further, the anterior module can be rigid for maintaining the lens in an optically-desirable orientation. Furthermore, the goggle can comprise an interchangeable lens mechanism to facilitate interchanging of lenses in the goggle.
