Abstract:
According to the present invention, an apparatus for manufacturing a multichannel electrode array for cranial nerve stimulation comprises: an electrode support (100) supporting a plurality of electric wires, and having a plurality of platinum rings inserted therein; a frame member (200) including a base (210), a pair of vertical frames (220), and a horizontal frame (240) to fix the electrode support (100); a rotating member (600) into the center of which the electrode support (100) is inserted, and which rotates such that electric wires are twisted, pair by pair, at the electrode support (100) so as to form a grid, when bobbins (700) that are wound with the electric wires slide; an elevating plate (500) rotatably and slidably supporting the rotating member (600); and a pair of left-side and right-side control units (800) and (900) which rotate the rotating member (600) such that the rotating member (600) slides along a length equal to that the grid. A multichannel electrode array manufactured according to the apparatus and method of the present invention can withstand unexpected forces and shocks as two pairs of electric wires (one disposed vertically and the other horizontally) move downward while alternately rotating so as to be twisted and form a grid, while a plurality of electric wires are vertically supported.
Abstract:
A self-leveling heat sink includes a spring-arm device having at least one aperture and at least one spring-arm is coupled to a substrate. The substrate has at least one package mounted thereon, so that when the spring-arm device is mounted to the substrate the at least one package passes through the at least one aperture. A heat sink operable to remove heat from the at least one package has at least one heat sink post operable to receive a heat sink clip located at the distal end of each of the at least one spring-arms. Each of the at least one spring-arms extending from an inside edge of the at least one aperture and operable to couple the heat sink to the at least one package.
Abstract:
A cable assembly apparatus for coupling a connector to a cable having a base supporting an interface pedestal dimensioned to receive the connector; an inductor coil coupled to an inductor coil actuator operable to move the inductor coil between a load position and an operation position proximate the interface pedestal; a grip clamp operable by a clamp actuator to move between an open position and a closed position above the interface pedestal; and a temperature sensor configured to read a temperature proximate the interface pedestal. A method for using the apparatus retains the preassembled connector and cable in an aligned orientation for controlled heating by the induction heater to heat a solder preform to solder the connector to an outer conductor of the cable.
Abstract:
A method for manufacturing wireless communication devices for use in tracking or identifying other items comprises a number of cutting techniques that allow the size of the antenna for the wireless communication device. Further, the chip for the wireless communication device is nested so as to be flush with the surface of the substrate of the wireless communication device. Rollers cut the tabs that form the antenna elements. In a first embodiment, a plurality of rollers are used, each on effecting a different cut whose position may be phased so as to shorten or lengthen the antenna element. In a second embodiment, the rollers are independently positionable to shorten or lengthen the antenna element.
Abstract:
A multiconductor cable is reduced in the possibility of break even for use at a place where the cable undergoes twisting, and a method can produce the multiconductor cable easily at a low cost. The multiconductor cable incorporates a plurality of wires that are arranged in a flat array with a specific pitch at both ends of them, that have an intermediate portion at which they are bundled together; and that have lengths different from one another, the lengths varying successively from the minimum length, Ls, to the maximum length, Lm. The multiconductor cable satisfies the formulae "D/E > 1/6," and "(Lm - Ls) > {(D 2 + E 2 ) 1/2 - E}," where D is the width of the cable at both ends, E is the distance between the ends of the cable, Lm is the maximum length, and Ls is the minimum length.
Abstract:
The invention relates to a retainer element (1) for at least one electrical component for assembly on circuit supports, such as, for example, circuit boards. The retainer element comprises at least one body (10), with at least one housing (11, 12, 13) for the component (200, 300, 400). The component may be introduced into the housing and the body (10) comprises at least one fixing element (2, 3), by means of which the above may be fixed to the circuit support (100). The fixing elements are, for example, embodied as clips (2, 3).
Abstract:
An improvement to a cathode used in an electrorefining or electrowinning of copper. The cathode has a solid copper head bar (2) with a horizontal groove (6) on its undersurface. The upper edge (9) of a stainless steel flat sheet has several holes (13) along its width and is vertically inserted into the groove. The stainless steel sheet is then mechanically attached to the copper head bar (2) by pressing the copper head bar against the stainless steel at the perforated points along the head bar. To increase the joint strength, the stainless steel sheet may be welded to the copper head bar as its upper edges at the underside of the head bar.
