A cutting tool is provided with an arcuate cutting blade that preferably engages a guide tool to create a curved resected surface during an arthorplasty procedure. In one embodiment, a depth of the cutting blade is sufficient to permit the simultaneous creation of resected surfaces on two bones that articulate, such as both the femor and the tibia for a given condyle, without the need to reposition the guide or the leg. In another embodiment, a cutting member has a generally rectangular cross-section along a longitudinal axis with a first and second surface having cutting teeth defined thereon and a third and fourth surface adapted to interface with a cutting guide positioned proximate the bone. In this embodiment, the cutting tool can resect the bone in two different directions without reorienting the cutting member.

A cutting tool for creating resected surfaces of bone during arthroplasty procedures has a single offset handle arm that presents a narrower effective width than a width of the cutting profile of the cutting tool along a longitudinal axis of the cutting profile. Preferably, the single offset handle arm creates a cutting tool with a generally L-shaped outline simultaneously accounting for soft tissue / incision geometry and bony geometry to accommodate both in facilitating ease of use and minimal displacement of soft tissue during cutting. The cutting tool can be snaked into position through an incision approximately the size of the width of the handle arm, instead of requiring an incision that is essentially the width of the cutting path of the cutting tool. In alternate embodiments, the cutting tool is a milling tool, a wireplasty cutting tool, a band saw or reciprocating cutting tool.

Cutting guides, cutting tools, and soft tissue management techniques permit the use of pivoting guide surfaces to facilitate in controlling the sweep or arc of a cutting tool used in connection with resection and arthroplasty procedures. In accordance with one embodiment, a guide structure is provided with one or more guide pivot aperture(s) and one or more guide pivot reference surface(s) that mate with a bushing assembly controlling a cutting tool. The bushing assembly possesses a bushing reference plan which mates with the pivot reference surface(s) of the guide structure and a bushing pivot pin which mates with the guide pivot aperture(s) of the guide structure. In one embodiment, a bushing guide lumen is operably coupled to the guide structure for articulated and / or axial guidance of the cutting tool.

The present invention provides catalytic adsorbents formed from doping activated carbon with a dispersed halide salt.

A method of predicating ultra-short-term wind power based on self-learning composite data source includes following steps. Model parameters of an autoregression moving average model are obtained by inputting data. A predication result is obtained by inputting data required by wind power predication into the autoregression moving average model. A post-evaluation is performed to the predication result by analyzing error between the predication result and measured values, and performing model order determination and model parameters estimation again while the error is greater than an allowable maximum error.

The within invention improves on the indirect evaporative cooling method and apparatus by making use of a working fluid that is pre-cooled with and without desiccants before it is passed through a Wet Channel where evaporative fluid is on the walls to take heat and store it in the working fluid as increased latent heat.

To prevent the deterioration of catalyst or the damage of a particulate filter caused by the rapid temperature rise of the particulate filter when the abrupt deceleration of an engine occurs, and avoid the deterioration of fuel consumption by depositing a large PM in the particulate filter and regenerating the same at once. A heat-absorbing area 4 is provided by forming a deeply clogged structure at the exhaust gas flowing-out side end of the particular filter 1 disposed in an exhaust pipe 2 of an internal combustion engine E. As the heat-absorbing area has a heat capacity larger than that in the other portions, the combustion heat is absorbed and dispersed even if the rapid chain reaction of PM combustion occurs, whereby it is possible to suppress the temperature rise of the downstream portion of the particulate filter liable to be high in temperature.

A longitudinal control law is designed to optimize the flying qualities when aircraft is set to approach configuration, i.e. when the flap lever is set to the landing position and landing gears are locked down. Under such circumstances, the effort of trimming the aircraft speed can be extremely reduced by the usage of a momentary on-off switch or other control in the sidestick, instead of or in addition to a conventional trim up-down switch, making easier the task of airspeed selection by the pilot. This control law provides excellent handling qualities during approach and landing, with the benefit of not needing or using radio altimeter information in safety-critical applications.
