Abstract: An implantable stimulation system including epidural lead for spinal cord stimulation that includes a paddle having a curved proximal end and lateral winged tips and an array of electrodes coupled to conductors within a lead body. The conductors couple to a pulse generator or other stimulation device. The curved and winged paddle provides more complete electrical stimulation coverage to targeted human tissue by minimizing the potential gap between electrodes and targeted fibers.

Abstract: A hand-grippable adhesive tape applicator is provided for building construction and other environments. The hand-held device has a frame supporting an applicator roller rotatably mounted at a forward portion of the frame, and tape spool also is rotatably mounted to the frame to support a roll of the transfer adhesive material and unreel transfer adhesive material to the applicator roll as the applicator roll moves against a substrate with the adhesive layer in contact therewith. A release liner take-up spindle is rotatably mounted to the frame between the tape spool and the applicator roll to take-up the release liner. A drive means interconnects the tape spool and release liner take-up spindle for synchronized rotation, and tape spool retaining means and take-up spindle retaining means restrict rotational speeds thereof to reduce slippage thereof.

Abstract: A parachute has a canopy and rigging lines with skirt assist lines connected between a point on each rigging line adjacent a lower edge of the canopy and a point on the interior of the canopy spaced from the lower edge. The arrangement is such that a portion of the canopy between the point and the lower edge is relieved of tension as the canopy is deployed to assist the opening of the canopy. The skirt assist lines are frangible. This prevents rapid deployment of the canopy to lower g-forces on the load in high speed opening.

Abstract: A variable-frequency digital ring oscillator provides small and consistent frequency adjustments throughout a locked range. The ring oscillator of the invention is standard cell placeable and operates at the technology limits to provide small and precise delay changes that is inexpensive to implement. The digital variable-frequency ring oscillator includes multiple macro delay elements forming an inverter ring circuit, each element having an individual macro delay unit that in turn is comprised of multiple adjustable delay units. All of these adjustable delay units are controlled by a single delay control signal.

Abstract: A digitally controlled oscillator includes an adjustable signal generating circuit adapted to generate an oscillation signal. A feedback loop receives the oscillation signal from the adjustable signal generating circuit. The feedback loop detects error in the oscillation signal and produces an error signal based on the error. The control logic circuit receives the error signal from the feedback loop and maintains the oscillation signal within a predetermined error range. Also, a state device that is connected to the adjustable signal generating circuit maintains a previous operating state of the adjustable signal generating circuit when the digitally controlled oscillator is temporarily powered down.

Abstract: A reserve parachute with air pockets at the apex of the canopy to allow rapid deployment of the reserve parachute without tangling with a malfunctioning main parachute. Skirt assist lines are provided to allow the lower edge of the canopy to spread on deployment and thus speed the opening of the canopy. In addition, ties may be provided between the pockets to maximize their effectiveness.

Abstract: An apparatus is disclosed for distributing a load applied thereto, such as by a shipping pallet. The apparatus comprises first and second thermoformed plastic sheets. The first sheet has a generally planar surface, a central indentation and a plurality of symmetrical peripheral indentations disposed around the central indentation, and a plurality of first ribs extending radially from the central indentation. The second sheet is joined with the first sheet and has a series of adjacent first channels which form a generally diamond-shaped patten. Each pair of adjacent first channels is separated by a raised portion including a groove and a pair of second ribs flanking the groove. Both the first channels and the grooves of the second sheet are recessed below a plane defined by the raised portions, the grooves being recessed to a depth less than the first channels.

Abstract: A floppy disk drive with automatic disc clamping and ejection is disclosed. The movement of the linear actuator is used to provide both the clamping and ejection, without other drive means. A pair of magnetic heads, positioned on opposing sides of a drive wheel, are fixed to a carriage, one engages the upper surface of the disc, the other the lower surface. Neither head moves relative to the other. The drive components are easily assembled providing a relatively inexpensive, yet reliable drive.

Abstract: A method and apparatus for depositing flock wherein flock fibers are fed at a controlled rate from a storage hopper through a screen into a propelling air stream. The air stream carries the fibers in a rotationally stabilized flow to an applicator gun where they may be electrostatically charged, and they are propelled by the air stream and deposited on the adhesively coated surface to be coated.

Abstract: An electrostatic flocking system having a supply hopper for controllably entraining flock fibers within a propelling air stream, and for feeding the entrained fibers to an electrostatic flocking gun. The fibers and propelling air pass through the gun and into a nozzle at the front of the gun having an elongated forwardly open chamber. An elongated electrode is carried within the nozzle chamber and is coupled to a suitable electric power source for electrostatically charging the fibers and for directing them forwardly over the entire length of the chamber toward the surface of an article being coated.
