Abstract: In a first embodiment, the present invention includes an instrumentation system for preparing a bone for soft tissue repair, the instrumentation system including a flexible drill pin capable of bending along a curved path; an aimer capable of engaging the flexible pin to bend the flexible pin; and a flexible reamer having a flexible portion along at least a portion of its length, the flexible portion comprising a plurality of laser cuts.

Abstract: Methods and systems are provided for operating an internal combustion engine having an exhaust system and a plurality of cylinders that utilize fuel and/or oil for combustion and engine lubrication purposes. In one example, a method comprises, while the engine is operating in a low-load mode or an idle mode, successively operating distinct subsets of said cylinders at a cylinder load sufficient to increase an exhaust temperature for burning unburned fuel and/or oil deposited in the cylinders or engine exhaust system. Herein, each successively operated subset comprises at least one but fewer than all of the plurality of cylinders, and the cylinders that are not currently being operated in a subset are operated in a low- or no-fuel mode.

Abstract: A toggle bolt suture anchor kit and method of using the kit is presented. The kit comprises a toggle bolt suture anchor and a toggle bolt delivery device. The toggle bolt suture anchor has at least one toggle bolt delivery device interconnection means. The toggle bolt delivery device has at least one toggle bolt suture anchor interconnection means. The toggle bolt delivery device enables the toggle bolt suture anchor to be pushed into its final position.

Abstract: An anchorage in tissue is produced by holding a vibrating element and a counter element against each other such that their contact faces are in contact with each other, wherein at least one of the contact faces comprises a thermoplastic material which is liquefiable by mechanical vibration. While holding and then moving the two elements against each other, the vibrating element is vibrated and due to the vibration the thermoplastic material is liquefied between the contract faces, and due to the relative movement is made to flow from between the contact faces and to penetrate tissue located adjacent to outer edges of the contact faces. For liquefaction of the thermoplastic material and for displacing it from between the contact faces no force needs to act on the tissue surface which is to be penetrated by the liquefied material. For this reason anchorage in tissue which has little mechanical stability is possible.

Abstract: A system is provided for controlling at least one fuel delivery characteristic during a combustion event within an engine. The system includes an accumulator having a variable volume, where the accumulator is configured to hold fuel at a variable pressure based on the variable volume. The system further includes a combustion chamber coupled to the accumulator. The variable volume is varied during the combustion event such that at least one fuel delivery characteristic of the fuel delivered from the accumulator into the combustion chamber is varied during the combustion event. A method and computer readable media are also provided for controlling at least one fuel delivery characteristic during a combustion event within an engine.

Abstract: A system for warming up an engine at an accelerated rate, the system including a control system configured to regulate at least one of a rotational speed and a horsepower load of the engine, a processor configured to evaluate a reading from the control system, and wherein the processor is further configured to adjust at least one of a rotational speed set point and/or a reference to engine speed regulator so that the engine may operate at an increased rotational speed without exceeding a predefined oil pressure limit. A method and a computer software code are also disclosed for warming up an engine at an accelerated rate.

Abstract: A diesel engine (10) wherein both the operating speed of the engine (RPM) and the timing of the fuel injection into the engine (AA) are cooperatively controlled to be responsive to both the temperature and the pressure of the air (30) used for combustion. A controller (44) receives a temperature signal (28), an air pressure signal (36), and a power demand signal (24) and executes control logic to produce a fuel injection control signal (46) and an engine speed control signal (48) for controlling a fuel injection system (16). A control strategy based on engine inlet air temperature and pressure or manifold air density may be useful for variable speed and power applications. For applications with discreet speed and power points, such as a locomotive, a speed and timing control strategy based on ambient temperature and pressure is useful for maximizing power during high altitude and/or high ambient/inlet air temperature operation.

Abstract: An apparatus and method for mounting electrical devices in a housing at an angle relative to the ground is provided. The apparatus comprises a housing having a top, bottom, and sides, each of which may be open, closed or ventilated. One or more electrical devices are located in the housing and are oriented at an angle relative to the horizontal ground. The electrical devices may be silicon controlled rectifiers that serve as a power bridge between an exciter and a power generator. A method for mounting electrical devices in a housing at an angle relative to the horizontal ground is also provided.
