Abstract: A system includes a first tube, a sharp coil at a distal end of the first tube, a second tube displaceable within the first tube, and a sharp housing at a distal of the second tube for storing fasteners. The housing can be positioned at a first tissue, and the coil rotated to advance the coil into engagement with the first tissue. The first tube is retracted to retract the first tissue, and then a first fastener is deployed at the first tissue location. Then, without removing the system from the patient, the distal end of the system is moved adjacent a second tissue location, and the process is repeated for a second fastener at the second tissue location. A suture extends between the first and second fasteners, and tension is applied to the suture to draw the first and second tissues toward each other to reconfigure the tissue.

Abstract: A method of controlling a concentration of hydrocarbons in exhaust gas from an internal combustion engine includes sensing an oxygen percentage of the flow of exhaust gas from the internal combustion engine and determining a concentration of hydrocarbons in the flow of exhaust gas.

The control module may then control at least one of a hydrocarbon injection rate for in-cylinder combustion of the internal combustion engine, and a hydrocarbon injection rate for a post combustion exhaust gas treatment process, based on the corrected oxygen percentage, to control the concentration of hydrocarbons in the exhaust gas.

Abstract: An engine assembly includes a camshaft having an exhaust cam lobe defining an exhaust lift region and an exhaust base circle region and an EGR cam lobe defining an EGR lift region and an EGR base circle region. The EGR lift region is rotationally offset from the exhaust lift region and the EGR base circle region is rotationally aligned with the exhaust lift region. An exhaust valve lift mechanism is engaged with an exhaust valve, the exhaust cam lobe and the EGR cam lobe and is operable in first and second modes. The exhaust valve remains closed when the EGR lift region engages the exhaust valve lift mechanism during the second mode and the exhaust valve is opened when the EGR lift region engages the exhaust valve lift mechanism during the first mode to provide exhaust gas flow into the combustion chamber during an intake stroke of the combustion chamber.

Abstract: Inspection apparatus comprises a feed system for delivering a stream of articles to an imaging zone. A camera generates image data from the stream at the imaging zone for processing by a computer. The computer comprises a pattern recognition system for identifying defects in areas from the image data, and for ranking identified defects. The pattern recognition system is programmed to operate according to multiple defect criteria. The computer is also coupled to a graphical user interface to display the areas identified from the image data as thumbnails on the interface arranged according to rank of the identified defects in the areas, in each of at least two defect criteria. The areas from the generated image data will normally be defined around each identified defect with the defect central therein. These areas, or thumbnails, can overlap.

Abstract: A method for controlling re-circulation of exhaust gas (EGR) in an internal combustion engine includes receiving a signal indicative of an engine operating temperature and comparing the engine operating temperature to a first predetermined IEGR threshold. When the engine operating temperature is less than the first predetermined internal EGR threshold, a first internal EGR mode is activated, whereby engine emissions may be reduced or combustion stability may be enhanced. When the engine operating temperature is greater than the first predetermined internal EGR threshold, the first internal EGR mode is deactivated, and a second internal EGR mode is activated, whereby emissions may be reduced as exhaust system heating is accelerated. When the operating temperature is greater than the second temperature threshold, the second internal EGR mode may be deactivated a third mode may be enabled with only external EGR.

Abstract: The present invention provides a clamp assembly which allows the surgeon to snap a bone fixation assembly onto a bone fixation rod at an intermediate location along the length of the rod. It is not necessary to “thread” the clamp onto the rod starting at the end and sliding it down the length of the rod to the desired location. In particular, this invention provides a novel clamp assembly for use with standard bone fixation rods, and bone pins. The clamp allows the interconnection of a bone fixation rod with a bone pin locking assembly including a bone pin vise. The clamp is a single-piece construction, having a jaw capable of loosely capturing the bone fixation rod when the surgeon presses the jaw onto the rod. The assembly may be rigidly fixed to the rod using a bolt which tightens the jaw onto the rod.
