Abstract:
A spinal cord stimulation (SCS) system includes multiple electrodes, multiple, independently programmable, stimulation channels within an implantable pulse generator (IPG) which channels can provide concurrent, but unique stimulation fields, permitting virtual electrodes to be realized. The SCS system includes a replenishable power source (e.g., rechargeable battery), that may be recharged using transcutaneous power transmissions between antenna coil pairs. An external charger unit, having its own rechargeable battery can be used to charge the IPG replenishable power source. A real-time clock can provide an auto-run schedule for daily stimulation. An included bi-directional telemetry link in the system informs the patient or clinician the status of the system, including the state of charge of the IPG battery. Other processing circuitry in the IPG allows electrode impedance measurements to be made. Further circuitry in the external battery charger can provide alignment detection for the coil pairs.
Abstract:
A method for highly reliable and durable electrical power distribution and a fusing block assembly for distribution of large electric currents to electricity-consuming devices. The invention is a machined block (10) of conductive material into which threaded connectors (20) for input wires are affixed through the use of slip-joint ferrules (23) which allow the connectors (20) to be tightened securely to block (10) without twisting the wires. Threaded output connectors (30) hold fuses (70) which are joined to output wire connector assemblies (40). The output wire connector assemblies (40) also include slip-joint ferrules (51) which allow the connectors (40) to be tightened securely without twisting the wires.
Abstract:
A shield for an electrical fuse, including an inner enclosure for housing the electrical fuse and a pair of outwardly flaring end portions extending from the opposite ends of the enclosure. The shield includes walls separating the inner enclosure from each of the outwardly flaring end portions, and a slot in the walls for the extension through that slot of at least a terminal portion of the electrical fuse. The shield may be made of a pair of identical housing pieces with mating tongue and groove elements disposed substantially along the peripheries of those pieces. Preferably, the tongue element of the housing pieces is disposed on the opposite side as the groove element of the housing piece. Each of the outwardly flaring ends, or alternatively the walls, may cooperatively form a seal to aid in preventing entry of moisture or dirt into the shield. A sealing portion that aids in forming the seal may comprise a resilient, compressible grommet. The outwardly flaring end portions include a pair of snap-locking elements for securing a separate, connecting section to the outwardly flaring end portions.
Abstract:
This power supply protective device for cars can be used to protect electric appliances when they are connected to cars. Such a protective device can protect expensive electric appliances used in cars such as laptop computers. When these appliances are in use, they make use of the extended power supply from the cigar-lighter base in cars. This invention can protect such a power supply source. The invention uses a simple inserting/connecting structure to wrap the thin lock-piece fuse inside and then insert it into the cigar-lighter base. Moreover, it is very easy to change fuses.
Abstract:
A fuse is attached to an inner wall surface of a cover body that opens and closes in a hingelike manner while arranged over an opening of a housing. A pair of connected terminals is fixed to the housing at a predetermined interval in a longitudinal direction. Terminals of the fuse are electrically connected to the connected terminals when the cover body is closed, so that a circuit formed by the electric wires connected to the end portions of the respective connected terminals is caused to conduct. When the cover body is opened, the terminals are electrically disconnected from the connected terminals so that the circuit is opened.
Abstract:
A fuse holder including a shell, two jacks mounted inside the shell at two opposite ends and respectively connected to the conductors of two electric wires, and a cartridge fuse mounted inside the shell and connected between the jacks, wherein each jack includes a first connector disposed at an inner side, a second connector disposed at an outer side, and a clamp connected between the first connector and the second connector, the first connector being a stepped, cylindrical element having a center through hole, which receives one electric wire, an embossed outside wall, and a screw rod at an inner end, the second connector having an inner thread at one end threaded onto the screw rod of the first connector, and an expanded split coupling portion at an opposite end plugged onto one end of the cartridge fuse, the clamp being connected between the first connector and the second connector and mounted around one electric wire, permitting the conductor of the corresponding electric wire to be firmly retained between the outside wall of the clamp and the inside wall of the second connector.
Abstract:
A female fuse assembly has a fuse housing, and first and second fuse-link terminals. Each fuse-link terminal includes a clip-receiving portion, and first and second clip abutments. The female fuse assembly also includes a fuse link connected between the first and second fuse-link terminals. The first and second female clips each include a clip body for operative engagement with the respective first and second fuse-link terminals. The first and second clips each also including first and second arm-connecting extensions, and first and second arms. The first and second arm-connecting extensions of the first clip are engaged with the respective first and second clip abutments of the first and second fuse-link terminals. The first and second arms of each first and second clip each have a first and a second branch. The first branches of the first and second arms of the first and second clips engage the respective first and second fuse-link terminals, and second branches of the first and second arms of the first and second clips engage a contacting surface of a male terminal to secure a snug fit between the male terminals, the fuse-link terminals, and the clips.
Abstract:
A cartridge fuse mounting structure including a fuse holder, a cartridge fuse mounted inside the fuse holder, two cylindrical fuse connectors respectively connected to two opposite ends of the cartridge fuse, two electric wires respectively connected to the cylindrical fuse connectors by a respective wire binding clamp, and two end caps respectively mounted around the electric wires and respectively fastened to two opposite ends of the fuse holder, wherein each cylindrical fuse connector has an inside annular groove, which receives one end of the cartridge fuse, a split coupling tube at one end clamped on one end of the cartridge fuse, and a radial screw hole at an opposite end mounted with a tightening up screw, which holds down the respective wire binding clamp and the respective electric wire.
Abstract:
An automotive fuse includes a pair of spring clips connected by a fusible bridge and a transparent shield extending laterally over the width of at least the bridge and a face of one of the clips. The shield is connected to only one of the clips, so that the other clip and any associated lead fall freely from the fuse when the bridge fuses in response to excessive current. The clips are adapted for engagement with matching clips on hot or utility leads in the circuits to which the fuses are connected. The shield can be tinted with color to correspond to the amperage rating of the fuse.
