Title: Enhanced temporal and resolution layering in advanced television
Inventor: DEMOS GARY A
IPC: H04N5/44
Filed: 2001-04-06
Granted: 2006-06-06
Abstract: A method and apparatus for image compression using temporal and resolution layering of compressed image frames (Figs. 8).      In particular, layered compression (Fig. 8, items 81, 85, and 86) allows a form of modularized decomposition of an image that supports flexible application of a variety of image enhancement techniques (Fig. 2). Further, the invention provides a number of enhancements to handle a variety of video quality and compression problems (Fig. 7). Most of the enhancements are preferably embodied as a set of tools which can be applied to the tasks of enhancing image (Fig. 8.,item 82, 86) and compressing such images. The tools can be combined by a content developer in various ways, as desired, to optimize the visual quality and compression efficiency of a compressed data stream. Such tools include improved image filtering techniques, motion vector representation and determination, de-interlacing and noise reduction enhancements, motion analysis, imaging device characterization and correction, an enhanced 3-2 pulldown system (Fig. 1), frame rate methods for production, a modular bit rate technique, a multi-layer DCT structure (Fig. 20), variable length coding optimization, an augmentation system for MPEG-2 and MPEG-4, and guide vectors for the spatial enhancement layer (Fig.8, item 87).

Abstract: An interference screw for affixing soft tissue grafts during anterior cruciate ligament (ACL) reconstruction comprises a threaded body axially extending between a face and a tip along a central axis, with the face advantageously being obliquely aligned with the central axis. The threaded body includes a proximal threaded section and a distal threaded section, each of which may be straight or tapered. The proximal threaded section is approximately 1 mm larger in diameter than the distal threaded section. The increased diameter of the proximal threaded section enables the interference screw to compressively secure the soft tissue graft against the cortical bone, while the distal threaded section compresses the soft tissue graft against the cancellous bone with an appropriately reduced force that is appropriate for facilitating bonding of the soft tissue graft to the cancellous bone and that is sufficient for minimizing any "bungee effect."

Abstract: A device for example for the harvesting of farmed bivalves (6) in water (4), the bivalves (6) being attached to and growing on a bivalve net (10) in the water (4). According to the invention, the device, a bivalve harvester (2), has a propulsion device arranged thereto, and is formed of a frame with for example at least one rotatable harvesting roller (90, 92), which is pressed and rotated against the bivalve net (10) and the bivalves (6) during the harvesting of the bivalves (6), so that the bivalves (6) are thereby scraped or milled loose from the bivalve net (10), after which the bivalves (6) are collected and sucked into a catching device enclosing the harvesting roller(s) (90, 92). The bivalves (6) and bivalve bunches (8) are then pumped by means of a pumping device in a downstream direction into a pipe for further transport and collecting onto a vessel or a device placed in the vicinity of the bivalve harvester (2). Bivalve bunches (8) may possibly be separated into smaller units in a debunching pipe (192) placed for example immediately downstream of the catching device.

Abstract: A hydroelectric power plant uses a plurality of windmills connected to compressed air generators to produce pressurized air. Pressurized air is used to drive water through a turbine to produce electrical power. The water is recycled and the power plant includes reserve pressurized air tanks to allow the plant to continue to operate when the wind levels are not sufficient to produce high pressure air. The power plant is designed to be operated on a continuous basis based on wind power. When the wind subsides and the reserve capacity has been exhausted, electricity can be drawn from the local utility supplier. When excess power is generated by the power plant, electricity from the power plant can be added to the grid of the local electricity supplier.

Abstract: A medical device for use in minimally invasive surgical procedures, resulting in less trauma, less blood loss and shortened recovery times. The medical device limits or alleviates the traumatic effects of incisions on the body. The apparatus includes a closure member and delivery systems for closing vessels in the body of a patient. The closure member is a hemostatic closure member for delivery to a passageway in a body of a patient for filling and permanently occluding the passageway and comprises a plug formed with one or more sheets of biocompatible extracellular matrix material. The one or more sheets are harvested from collagenous tissue and processed to remove cells. The plug is implantable in the passageway to fill the passageway. The plug does not have an open lumen extending longitudinally through the plug.  The biocompatible extracellular matrix material is effective to stimulate tissue ingrowth from the adjacent native tissue when the plug is implanted in the passageway such that the passageway becomes occluded with native tissue.

Abstract: A rock stabilizing apparatus for use with adhesion materials has a tensionable reinforcing member having a threaded portion at one end and an opposite end. The member-threaded portion threadably receives a nut and a bearing plate is retained on the member-threaded portion by the nut. A shearing element is provided for temporarily fixing the nut in a first operating position. At a predetermined torque shear, the shearing element fails and the nut is freed to advance on the threaded member portion from the first temporary operating position to a second permanent operating position. The first fixed operating position is located at the top end of the member-threaded portion. The second operation position is located at the bottom end of the member-threaded portion so that the bearing plate is in abutting contact with the face of the rock formation. In its first operating position the nut and reinforcing member may be rotated together for mixing the adhesion materials located within the drill hole.

Title: Steerable parachute control system and method
Inventor: PRESTON DANIEL
IPC: B64D17/04
Filed: 2002-12-09
Granted: 2011-07-05
Abstract: An autonomous guided parachute system for cargo drops that divides the requirements of guidance and soft landing into separate parachutes. Said invention includes a high wing-loaded ram air parachute for guidance, a larger round parachute for soft landing, a harness/container system, flight computer, position sensors and actuation system. The system is dropped from an airplane, a predetermined period of drogue fall ensures a stable position prior to deploying the guidance parachute. The flight controller determines a heading to intersect with an area substantially above the desired target and controls the guidance parachute via pneumatic actuators connected to the parachutes steering lines to fly on that heading. At a minimum altitude prior to the systems impact with the ground the flight computer transitions the system from the fast high performance guidance parachute to a larger landing parachute by releasing the guidance parachute to static line extract and deploy the landing parachute. If the system reaches a position substantially above target area prior to the parachute transition altitude flight computer controls the system into a spiral dive or other rapid altitude dropping maneuver until the transition altitude is reached. Once transitioned to the landing parachute the system descends for a brief period unguided under the landing parachute until touchdown.
