Title: Method and apparatus for displaying different shades of gray on a liquid crystal display
Inventor: GARRETT JAMES H
IPC: H04N3/12
Filed: 1989-09-25
Granted: 1994-01-11
Abstract: METHOD AND APPARATUS FOR DISPLAYING DIFFERENT        SHADES OF GRAY ON A LIQUID CRYSTAL DISPLAY               ABSTRACT OF THE DISCLOSURE     A method and apparatus are disclosed which provide a means for both spatially and temporally resolving the on/off states of a two-state display device such as a liquid crystal display to provide apparent shades of gray.  A particular feature of this method is that the cycling between on and off states is not performed in a discernible pattern.  Rather, a pseudo-random pattern is utilized which repeats only after many cycles.          Additionally, when the method disclosed herein is utilized, adjacent pixels, when selected to display the same shade of gray, do not cycle on and off in synchronization, but rather utilize out-of-phase cycling patterns.  This spatial resolution reduces perceived flicker in the display and provides a more stable image.          In one embodiment, eight shades of gray are provided.          The shades are generated by cycling individual pixels such that when averaged over time, they are:  always off; on 20% of the time; 33% of the time; 40% of the time; 60% of the time; 67% of the time; 80% of the time; or, on at all times.

Title: Dilatation catheter for the carotid artery
Inventor: AHMADI RAMAZAN A
IPC: A61M29/02
Filed: 1989-09-25
Granted: 1994-01-25
Abstract: DILATATION CATHETER FOR WIDENING OF STRICTURES Abstract A dilatation catheter intended in particular for treatment of strictures in the carotid artery has at its front end a dilatation balloon, which is inserted in the folded state into the carotid artery and is inflated in order to widen the stricture.  In front of the dilatation balloon a sealing balloon is arranged which serves to seal off the carotid artery downstream of the stricture, in order thereby to prevent a migration of any stricture material which may become detached during treatment, and thus to avoid the risk of an embolism.  Between the dilatation balloon and the sealing balloon there is a draw-off and inlet opening through which, after widening and with the sealing balloon inflated, detached stricture material can be drawn off or washed away.

Abstract: The present invention relates to a target-recognition procedure for a missile with a seeker head, the missile rotating as it falls to Earth, while scanning the ground for possible targets.  The geometrical dimensions of possible targets in the direction of the scanning track (Y-direction) and in the direction perpendicular to the scanning track (X-direction) while taking into account the distance r between the missile and possible tar-gets are determined and compared with corresponding stored values.          In order to avoid any distortion in the Y direction of the target that has been scanned, the invention proposes that the angular velocity .omega. of the missile and the angle .PHI. between the axis of rotation and the axis of symmetry of the missile be determined continuously during the scanning process and image correction values with which a correction of the geometrical dimensions of the possible target in the Y direction can be made be computed from these values.

Granted: 1994-02-08
Abstract: ABSTRACT OF THE DISCLOSURE        A flow control system for use in a compressible fluid fuelled internal combustion engine includes a pressure regulator for reducing the pressure of a fuel stored at a first pressure to a lower second pressure suitable for metering.  The regulator includes a regulating valve controlling communication between an inlet fluid manifold and a regulated fluid manifold and is arranged to produce a drop in pressure of the flowing fluid through the valve to the second pressure.  The regulator further includes a relief valve arranged to open to exhaust fluid when the pressure in the regulated fluid manifold rises above a predetermined level.  The regulator is also provided with heating means for heating the regulator body to compensate, to some degree at least, for the drop in temperature in the fluid as the fluid expands on passing through the regulating valve.  There is further provided a fluid metering device comprising a plurality of fluid line for communication between an inlet fluid manifold and a metered fluid manifold. Bistable valves of various orifice sizes are provided, one in each of the fluid lines.  The device also includes sensors for determining parameters of the inlet fluid sufficient to determine potential mass flow of fluid through each of the valves, and valve controls for activating valve actuators to open the valves in combinations and for time intervals to give a desired total mass flow of fluid through the valves.  The total fluid flow passing form the metering device comprises a base flow component established by opening selected control valves to provide a continuous predetermined flow, discrete step changes in the base flow component being provided by opening and closing combinations of control valves.  Increments of fluid flow between the discrete steps are provided by opening at least one pulsing valve for fraction of a predetermined time period to provide a desired average flow over the time period.

Abstract: A front wheel side luggage carrier (1) for bicycles comprises a strut arrangement (4) having two struts (7, 8), which when in the position of use extend substantially vertically and approximately parallel to a plane that intersects the front axle of the bicycle at right angles, and having an upper and a lower attachment arrangement (5, 6). Via these arrangements, the side luggage carrier (1) is secured to adjacent legs of the front wheel fork (2) at two points, one of which is located near the front axle and the other is spaced apart therefrom. In order to provide a simple structure, which even under adverse conditions will not tend to vibrate during the ride and which will be largely independent of the shape of the front wheel fork (2), the two vertical struts (7, 8) are joined integrally together at their lower end by means of a connecting cross portion (11), which bears the lower attachment arrangement (6). At their upper ends, the two vertical struts (7, 8) are bent toward one another, forming two transverse bent-over portions (23, 24) in alignment with one another, which in turn are bent at their free ends, forming two support struts (27, 28), towards the lower attachment arrangement (6) on which the support struts (27, 28) are anchored. The upper attachment arrangement (5) is provided on the support struts (27, 28).

Abstract: The invention relates to a process for manufacturing a fixed, sealed pipe connection between a smooth pipe end and a press fitting which surrounds said end, the press fitting being compressed in a force-fitting and positively locking manner with the inserted pipe end, by means of a compression tool which is placed on it. The invention is characterised in that, once the compression tool is placed in position, the pipe, which has already manually been inserted into the press fitting, and the press fitting, which has been pushed onto the pipe end, are forcibly subjected to a variable force, acting axially, by means of a device arranged on the compression tool, and the closing movement of the jaws for the compression of the press fitting cannot be released until this force assumes a value which is greater than a predetermined adjustable threshold value.
