Abstract: An electronic apparatus having a casing of a main body portion and a slide tray mounted on the casing for being extracted forward via an opening surface of the casing. A resilient member is mounted on one of the casing and the slide tray for sliding in the direction of extraction. An engagement recess is formed in the other of the casing and the slide tray or the resilient member, and an engagement member is formed in the resilient member or the other of the casing and the slide tray. The engagement member is engaged in the engagement recess when the slide tray is in the pull-out position.

Abstract: A portable computer is provided with retractable ear phones. The ear phones can include ear buds with an outer cushion. The ear buds are retractably coupled with the portable computer by an audio cable. A retraction mechanism retracts the audio cable and ear buds into the computer. The portable computer has a cut out sized to receive the ear buds therein, which creates a place to store the ear buds during periods of non-use. To use the ear buds, a user removes the buds from the storage position, and pulls the audio cable from the computer. Pulling the audio cable activates the ear buds and disables an audio output device on the portable computer. To return the ear buds to a storage position, a retraction actuator is depressed which retracts the audio cable into the portable computer. Alternatively, the ear buds can be replaced or used in addition to an audio input device. The ear buds and/or audio input device can be provided on other devices, such as a portable keyboard.

Abstract: A rack mountable cable distribution enclosure. The cable distribution enclosure includes a tray that slides forwards and backwards out of the cable distribution enclosure. The tray incudes an adapter plate bracket which receives a plurality of adapter plates. The adapter plates are mounted in a horizontal orientation, parallel to the sliding tray. This reduces the height of the cable distribution enclosure for installations where less space is available. The adapter plate bracket is angled relative to the sliding tray to prevent bending of the cable.

Abstract: For use with a rack having a carrier backplane and capable of receiving modular circuit packs therein to be coupled to the carrier backplane, a circuit pack cable adapter that allows the modular circuit packs additionally to process signals originating from other than the carrier backplane, and a method of operation thereof. The circuit pack cable adapter includes: (1) a cable interface proximate a rear end of the circuit pack cable adapter and (2) an extension cable, coupled to the cable interface and couplable via the cable interface to a main cable passing through an aperture in the carrier backplane proximate the rear end, the extension cable deployable from a front end of the circuit pack cable adapter to at least one of the modular circuit packs to allow the modular circuit packs additionally to process signals originating from the main cable.

Abstract: A core for an elastomeric tubing assembly is produced from a ribbon helically wound on itself to form a cylindrical tube. The edges of the ribbon are formed to interlock with each other and are contoured to facilitate ultrasonic welding of the edges. A support member is coextruded in the ribbon to provide increased resistance to premature collapse of the tube.

Abstract: A rack mountable cable distribution enclosure. The cable distribution enclosure includes a tray that slides forwards and backwards out of the cable distribution enclosure. The tray includes an adapter plate bracket which receives a plurality of adapter plates. The adapter plate bracket holds up to 12 adapter plates, each of which holds a variety of adapters. In fiber optic cable applications, each adapter plate can hold 6 duplex adapters, or 12 fibers, providing a density of 144 fibers.

Abstract: A circuit body (4) is received in an S-shaped configuration in a receiver (3) in a door. A protector (5) with a connector (6) is outwardly slidably provided inside the receiver (3). A circuit body fixing member (12) is provided at a front portion of the receiver (3), and a guide roller (15) is provided at a rear portion of the protector. The circuit body is wired from the fixing member (12) via the guide roller (15) into the protector and to the connector (6).Alternatively, a circuit body fixing member (12) and a guide roller (23) may be provided at a front portion of a receiver (10), the latter in such a manner as to be positioned inside the protector 27. The circuit body is held down by the guide roller (23) inside the protector.The circuit body is smoothly expanded and contracted with the opening and closing of the door.

Abstract: A core for a cold-shrink tubing assembly is produced from a ribbon helically wound on itself to form a cylindrical tube. The edges of the ribbon are formed to interlock with each other and are contoured to facilitate ultrasonic welding of the edges.

Abstract: A housing device for the retractable storage of a wire, cord or cable which is capable of operationally interconnecting electronic equipment, such as portable speakers and radios, while the interiorly coiled end of the wire, cord or cable remains coiled around a rotatable spool during connection. In its preferred embodiment, the housing device has a cover with connection ports therethrough. A radio connected to the connection ports becomes operationally connected with the interiorly coiled end of the wire, cord or cable through electrically conductive means integral with the spring-driven spool. The outer end of the coiled wire is then extended through an opening in the housing cover and connected to a portable speaker. The opening in the housing would be just large enough to accommodate the wire. A device larger in diameter than the wire would be attached at the near end of the exposed wire to prevent it from retracting all the way back inside the housing.

Abstract: A cable device for connecting electrical apparatuses with a power source or housing parts of electrical apparatuses with one another has a foldable electrical cable which has a plurality of folds with folding regions therebetween, and fixing elements which fix bending points in the folding regions against turning movements.

Abstract: A service transport unit for providing utilities to a parked aircraft, by way of a utility bundle, comprising a box attached to a passenger loading bridge, at least one slider and corresponding utility bundle tracker slidably mounted within the box wherein the utility bundle is fixed to the outboard terminus of the slider. The slider is mounted in the box and affixed to the passenger loading bridge so that it is pulled from within the container by extension of the passenger loading bridge, and pushed back into the box when the bridge is retracted. The utility bundle is passively extended and retracted by movement of the slider. The slider and utility bundle tracker also serve to guide the utility bundle and prevent it from tangling or kinking during movement of the passenger loading bridge.

Abstract: A cable carrier/retractor for supporting, protecting and guiding a cable to an equipment drawer in a cabinet including a framework while at the same time allowing for addition or removal of cables without any disassembly of the mechanism. The carrier supports a cable from an entry position adjacent to the framework of the drawer to an exit position adjacent to the back panel of the drawer. The carrier generally comprises a first having an entry end for supporting a cable from the entry position to an intermediate position, and a second channel for supporting the cable from an intermediate position to the exit position, a hinged mount connecting the first channel to the frame, and an intermediate hinge for connecting the channels. In a preferred embodiment, a retaining hinge connected to a drawer-mounted slide member or the drawer back panel holds the exit end of the second channel in a position adjacent to the back panel.

Abstract: An apparatus for accommodating an electrical cord in a heated toilet seat having a toilet seat body and a base cover pivotally connected to each other, wherein an electrical cord adapted for electrical connection between a heater mounted within the toilet seat body and a controller therefore is secured at one by a grommet provided on the base cover and at the other end by a cord fastener in the toilet seat body. Sufficient cord slack is provided in the toilet seat body so that the cord may be retracted or extended during the pivoting of the toilet seat body. The cord slack is in the shape of a loop, and a guide stopper is positioned within the loop to guide the cord during extension and retraction and limit the maximum extension of the cord.
