Abstract: If the components of a surgical instrument are not properly calibrated, errors may occur in the operation of the surgical instrument and consequently a control system for controlling the surgical instrument may lose its effectiveness.  This problem may be complicated where a variety of different types of surgical instruments are used with an electro-mechanical device. The present invention provides a system for calibrating a surgical instrument comprising: an electro-mechanical actuator including a memory unit storing at least predetermined calibration data for a number of different surgical instruments; a surgical instrument of the number of surgical instruments actuatable by the electro-mechanical actuator, the surgical instrument having first and second components that are moveable relative to each other; each surgical instrument including a memory unit storing at least predetermined calibration data corresponding to the surgical instrument, wherein the calibration data of each surgical instrument corresponds to a position of the surgical instrument, the position of the surgical instrument being a position of the first and second components relative to each other, wherein the calibration data of the surgical instrument includes a correction factor that corresponds to a difference between an actual amount of actuation required to actuate the surgical instrument from a first position to a second position, and an expected amount of actuation required to actuate the surgical instrument from the first position to the second position; and a processor configured to determine a position of the surgical instrument in accordance with at least one of the predetermined calibration data of the electro-mechanical actuator and the predetermined calibration data of the surgical instrument.

Abstract: An easily manufactured large boom construction includes a plurality of main tube support sections fabricated from plate material of differing material thickness, grade and section dependent on load. The tube support sections include apertured areas which provide a preliminary snap-fit of the main tubes to significantly reduce need for additional fixturing. The opposite ends of diagonal tubes pass through apertures in the fabricated support sections for accurate tube location without complicated weld fixtures or precise tube length and cut end angle tolerances. The tubes are welded on opposite sides of the sections to eliminate need for tube-to-tube connections or connections wherein a cut end edge has to be precisely placed against a planar surface. An inverted right triangle boom cross section with wing over-top fold configuration ability provides strength, stiffness and infinite nozzle placement possibilities.

Abstract: Selon l'invention, l'introduction de nanotubes dans un liquide permet de modifier les propriétés physiques et/ou chimiques de ce liquide. En effet, la dispersion de nanotubes dans des liquides permet de réaliser des améliorations en termes de transfert de chaleur, de propriétés électriques, de viscosité et de pouvoir lubrifiant. Toutefois, les nanotubes réagissent comme des particules hydrophobes et tendent à s'agglomérer dans les liquides. L'invention concerne des procédés destinés à préparer des dispersions stables de nanotubes et consistant à identifier des tensioactifs/dispersants pouvant disperser les nanotubes de carbone dans un milieu liquide aqueux ou à base de pétrole. Un dispersant approprié est choisi pour le nanotube de carbone et le milieu à base d'eau ou d'huile, ce dispersant étant dissous dans le milieu liquide, d'où la formation d'une solution. On ajoute alors le nanotube de carbone au dispersant contenant la solution par agitation, ultrasonication et/ou des combinaisons correspondantes.

Title: Apparatus for driving and adjusting of flaps hinged to an aircraft
Inventor: POHL ULRICH
IPC: B64D45/00
Filed: 2004-12-22
Granted: 2011-07-26
Abstract: Flaps, for example leading edge flaps and/or trailing edge flaps of an aircraft wing, are driven and adjusted by respective drive units. Drive shafts of neighboring flaps are coupled to each other by a differential gear. The differential gear is thus coupled to a main drive shaft which is driven by a main drive unit. Additionally, the differential gear is coupled to a secondary drive unit. The main drive power and the secondary drive power and thus the respective flap motions are super-imposable on each other, which permits operating the flaps independently of each other or in synchronism with each other.

Abstract: An extended nip press machine, similar to those used in the paper industry, for use in the leather industry to remove water from hides after the tanning process. The leather press consists of a shoe whose surface substantially matches the radius of an opposing pressure roll. Moving across the shoe is an endless belt, which is lubricated by a thin film of oil. Between the belt and corresponding pressure roll pass two endless felt belts, which are the means of conveying the leather hides. The nip formed by the shoe press is dramatically longer than a conventional press nip, thereby increasing the dewatering efficiency of the leather press.

The trolley is provided with pairs of wheels arranged to engage opposing bearing surfaces in each of two channels provided in the rail assembly. Each bearing surface has a central portion and two side portions shaped to fit flush against a curved edge surface of each wheel. This allows the wheels to bear against the surfaces in multiple directions, thereby allowing rolling motion of the trolley along the rail assembly as well as loading of the trolley in any direction not parallel to said motion. As a result, the apparatus can be oriented at any angle about a longitudinal axis thereof during installation, adding to the versatility and adaptability of the apparatus.

The transcoder reads header information (304) from an input bitstream and provides a corresponding header in the new format for the output bitstream. In one embodiment (Fig. 3), a low complexity front-to-back transcoder (with B frames disabled) avoids the need for motion compensation processing. In another embodiment (Fig. 4), a transcoder architecture that minimizes drift error (with B frames enabled) is provided. In another embodiment (Fig. 5), a size transcoder (with B frames enabled) is provided, e.g., to convert a bitstream of ITU-R 601 interlaced video coding with MPEG-2 MP@ ML into a simple profile MPEG-4 bitstream which Contains SIF progressive video suitable for a streaming video application.
