摘要： Suture passer systems for tissue suspension and tissue compression, and more particularly for tongue suspension, are described. The system can include at least a first elongate tubular body or shaft, a needle having a lateral bias carried by the elongate body, and a retrieval element operably connected to the elongate tubular body. The needle can have a substantially straight configuration when located within the elongate tubular body, and be configured to exit an opening at or near a distal end of the elongate tubular body and assume a laterally biased or curved shape to form a path through tissue. The needle is configured to carry a suture. The retrieval element can be configured to retrieve the suture carried by the needle after the needle has formed a curved or otherwise angled path through tissue. The system can also include one or more bone anchors to secure the suture loops. Methods of placing one or more suture loops into tissue, such as the base of the tongue, are also described.

摘要： A knotless suture anchor provides a method for securing soft tissue to a rigid structure such as bone. The anchor has an inner member that receives suture thread and rotates within an outer tubular member. As the inner member rotates, the suture thread is wrapped onto the inner member thereby increasing contact with the outer tubular member which applies pressure to the wrapped suture thread to retain it in position on the inner member while simultaneously and adjustably tensioning the suture thread. A ratchet prevents undesirable counter-rotation, although the ratchet can be released to permit loosening of the suture thread. Also described is a suture bridge and suture platform for providing further stabilization of a tendon. A method for repairing rotator cuff tears is also described.

摘要： A high-speed, area efficient, low-power absolute value arithmetic unit that efficiently produces the absolute value of the difference of two input operands. This arithmetic unit is adaptable to provide other output functions. Further, the arithmetic unit of the present invention may be utilized as a data path element in a high performance floating point arithmetic unit. The present invention includes a propagate and generate block, a carry-chain-and a difference multiplexer. Operands A and B are received by the absolute value arithmetic unit. The propagate and generate block converts operands A and B into propagate signals and generate signals. The carry-chain-receives propagate and generate signals and produces carry-chain-propagate signals and carry-chain-generate signals for every bit, where the most significant carry-chain-generate signal is used to indicate a borrow. The difference multiplexer receives the carry-chain-propagate and carry-chain-generate signals as well as propagate singals from the propagate-and-generate block and produces A-B and B-A. The difference multiplexer then selects either A-B or B-A to produce as an output the absolute value of A-B. The borrow signal acts as the selection means for obtaining the absolute value of A-B. In either case, .vertline.A-B.vertline. is obtained with essentially the same amount of hardware as only one core subtractor. The present invention uses approximately half the amount of hardware as the fastest conventional absolute value arithmetic units and therefore is approximately 50% more compact. The entire absolute value arithmetic unit of the present invention requires essentially the same amount of area as only one conventional adder/subtractor. In addition, the present invention sacrifices no speed to achieve its smaller size and consumes less power than a conventional absolute value subtractor.

摘要： An embodiment of the present invention is a portable hydrogen generation system for operating a vehicle powered by either the hydrogen internal combustion engine or a fuel cell using active metals such as sodium potassium, magnesium, aluminum or iron in the form of an emulsion, and a method thereof. The emulsion comprises a metal powder pre-mixed with oil. In the case of sodium, potassium and magnesium, the metal is reacting with water at or near room temperature. However, in the case of aluminum and iron, the metal is reacting with alkali hydroxide solutions. The system is controlled and managed by a microprocessor in order to generate hydrogen on demand at or near room temperature with a very high efficiency.

摘要： A system and method for providing antialiased memory access includes receiving a request to access a memory address. The memory address is examined to determine if the memory address is within a virtual frame buffer. If the memory address is within a virtual frame buffer then the memory address is transformed into one or more physical addresses within a frame buffer that is utilized for antialiasing. The frame buffer may be a single memory space containing subpixel information corresponding to pixels of the virtual frame buffer. Subpixels located at the physical addresses within the frame buffer are then accessed. The disclosed invention provides for direct access by a software application.
