Abstract: A microprocessor controlling a shuttle shift transmission may be programmed while the gearshift lever is in neutral to preselect a forward and reverse gear into which the transmission is shifted when the gearshift lever is moved to a forward or reverse position. The microprocessor may also be programmed so that, in shifting between forward and reverse, the forward and reverse gears selected differ by a pre-programmed amount. The microprocessor may be programmed to control vehicle deceleration by selecting gears in the transmission so that the transmission and/or the vehicle engine become a load for decelerating the vehicle. In a diagnostic mode, the microprocessor executes a routine to develop a clutch calibration value which may later be used to insure uniformity of clutch operation in different vehicles, or in the same vehicle over a period of time. The normal speed ratio matching which normally takes place when shifting gears may be manually overridden by operator manipulation of the gearshift lever. The override may either terminate speed ratio matching for a particular shift, or the override may be effective for a fixed interval of time.

Title: Contact lens packing solutions and methods for improving the comfort of disposable contact lenses
Inventor: TONGE STEPHEN RONALD
IPC: G02C13/00
Filed: 1998-06-05
Granted: 2006-11-21
Abstract: The present invention is directed to new and improved solutions for packaging contact lenses and to methods for treating contact lenses with such solutions to improve the comfort of the lenses during wear.  In particular, the present invention is directed to packing solutions comprising certain non-ionic surfactants containing a poly(oxyalkylene) copolymer and having a molecular weight of 4000 to 30,000. Such surfactants are retained on the surface of an unused lens for extended periods of time, resulting in surface modification that persists in the eye, thereby providing significant improvement in the wetting properties of fresh contact lenses used for the first time and, moreover, even several hours after lens insertion, preventing dryness and improving lubricity.

Abstract: Dispositif de stockage sur support, qui comporte un filtre intégré destiné à manipuler des flux de données basés sur l'horloge universelle lorsqu'ils sont écrits dans le dispositif de stockage sur support ou lus sur ce dernier. Ledit dispositif manipule également des flux de données qui ne sont pas écrits dans ce dispositif ou lus sur ce dernier. De préférence, le filtre intégré situé dans le dispositif de stockage sur support est un canal de transmission de données isochrone qui va recevoir des instructions programmées provenant d'une unité de commande externe et manipuler des flux de données selon les instructions programmées en temps réel, cordonnées avec l'horloge universelle. Alternativement, le canal de transmission de données isochrone comprend un logiciel microprogrammé fixe pour effectuer les manipulations appropriées. Le dispositif de stockage sur support est de préférence également couplé à une structure de bus série IEEE 1394-1995. Etant donné que les flux de données sont reçus par le dispositif de stockage sur support pendant une opération d'écriture, ces flux de données peuvent être mis dans un format différent par le filtre intégré avant d'être stockés sur le support dans le dispositif de stockage sur support. Etant donné que les flux de données sont transmis depuis le dispositif de stockage sur support pendant une opération de lecture, ces flux de données peuvent être mis dans un format différent par le filtre intégré avant d'être transmis sur une structure de bus série IEEE 1394-1995. Dans les deux cas, l'horloge universelle peut être utilisée pour synchroniser les flux de données. Le dispositif de stockage sur support utilise également le filtre intégré pour manipuler des flux de données transmis entre deux autres dispositifs sur la structure de bus série IEEE 1394-1995.

Abstract: A multi-frequency tone detector with analysis window (i.e. filter size) chosen such that spectral nulls are located at adjacent frequencies of interest. The decision logic block of the tone detector uses the roll-off characteristics of the filter in conjunction with background noise to determine a threshold pass/fail for any tone that has deviated excessively from its nominal value. The foregoing aspects of the invention result in simple filter design (i.e. reduced order) relative to prior art tone detectors.

Abstract: A print-medium transport unit including discharge rollers, a paper guide, and a lock member. The discharge rollers transport post-printed paper toward an outlet and can hold the leading end of the paper. The paper guide is placed upstream from the discharge rollers, and guides the leading end of the paper into the discharge rollers. The paper guide is rotatably supported so that the upstream side thereof opens a transport path of the paper, whereby when the leading end of the paper is held by the discharge rollers, the transport path allows the paper to be curved like a loop. The lock member locks the rotation of the paper guide when the leading end of the paper is guided into the paper guide. When the leading end of the paper reaches a predetermined position, the locking of the lock member is released.

Abstract: A baled crop material processor for disintegrating baled crop material comprising a container, a disintegrator, a discharge opening and means for manipulating the crop material for disintegration by the disintegrator. The container, receives and contains the crop material. The disintegrator comprises a flail roller that is mounted within the container and has a number of flails pivotally mounted about it. The flail roller rotates about its own longitudinal axis in either a clockwise or counter-clockwise direction. The discharge opening is at the bottom of one of the side walls to discharge the disintegrated crop material either to the left or to the right of the processor and in a bidirectional processor, the operator may alternate between sides. The manipulation means comprises manipulator rollers having paddles positioned at an angle to the length of the roller to rotate the crop material without substantially breaking the crop material apart. The paddles are channel shaped with outwardly curved ends to grasp the baled crop material for rotation and then to pull out of the crop material due to the curved end as the roller is rotated. Further, the angled paddles guide the crop material longitudinally toward the centre of the crop material processor away from the front and back walls. Moreover, the sidewalls of the container are shaped to have a protrusion projecting into the container in close proximity to the paddles, a spacing below the protrusion to prevent the accumulation of loose material, and outwardly sloped wall portions above the protrusion.
