Title: Image rendering system and method for generating stochastic threshold array(s) for use therewith
Inventor: KOLPATZIK BERND W
IPC: B41J2/52
Filed: 1996-03-22
Granted: 1999-11-16
Abstract: An image rendering system, for generating discrete tone image data representing a continuous-tone image for rendering by a rendering device, the image rendering system includes a stochastic threshold array generating arrangement and an image data processing section. The stochastic threshold array generating arrangement generates a plurality of stochastic threshold arrays from a random seed pattern that have been subsequently optimized to reduce image artifacts in the rendering of tones. Each pattern is optimized to reflect (i) a selected trade-off between grain and possible mottle in the rendered image, (ii) distortions introduced by the rendering device in rendering an image defined by the pattern and an observer in viewing the image, and (iii) boundary effects so that the patterns, when tiled together, have optimal visual characteristics proximate their respective edges. The image data processing section processes the continuous tone image data in relation to the stochastic threshold arrays generated by the stochastic threshold array generating arrangement. The image data processing section may be used to either randomly tile, or tile in an ordered way, the stochastic threshold arrays over the continuous-tone image data and generates the discrete tone image data in response to correspondingly positioned pixels of the continuous-tone image data and threshold values of the stochastic threshold arrays.

Abstract: The invention concerns a method and device for removing ticks from humans and animals. The device comprises: a base part (1) with at least one opening (2a, 2b), a thread loop (6) of resilient material which is arranged to be drawn into the opening (2a, 2b) under the effect of a spring member (5). The cross section of this opening relative to the thread loop (6) is such that the loop (6) outside the opening (2a, 2b), whilst being drawn thereinto, gradually decreases in size. Operatively connected to the thread loop (6) is a member (4, 4a) arranged such that, against the effect of the spring member (5), it shoots the thread loop (6) out of the opening (2a, 2b). According to the method of the invention, owing to pressure being exerted on the pushbutton (4a), the loop (6) is ejected from the opening (2a, 2b), laid around the tick and, since pressure is no longer exerted on the pushbutton (4a), can be drawn into the opening (2a, 2b). The loop (6) is then rotated one turn and the tick releases its grip within approximately three seconds.

Granted: 2002-02-26
Abstract: A speed control device is provided such that the speed of DC motors is controlled to remain constant with varying voltages supplied from a power source. A given application for such a speed control device is in the use of portable, hand-held Metal Inert Gas (MIG) welders. The power requirements of a portable MIG welder are twofold. Power is required for the generation of a welding current to enable the workpieces to be sufficiently heated and thus, welded together, and power is also required to drive a wire spooler which provides wire at a constant rate, leading to accurate and consistent welds. The speed control device provided ensures constant power delivery for both powerrequirements, regardless of variations in the voltage of a power supply and irrespective of a mechanical load asserted on the welder.

Abstract: A wireless coiled tubing joint locator for locating joints or collars in a production tubing string. The joint locator is adapted for running into a well on coiled tubing, and other downhole tools may be connectable to the joint locator. An electromagnetic coil assembly senses the increased mass of a pipe joint, and provides a signal to an electric circuit which generates a momentary electric output signal received by a pilot solenoid valve. The solenoid valve momentarily opens a pilot passageway which activates a piston to close a circulation port in the joint locator. This closing of the circulation point results in an increase in a surface pressure reading observable by the operator. A rupture disk is provided so that pressure cannot be applied to any downhole tool below the joint locator prematurely, and a seat sleeve is provided to prevent premature communication of fluid to the rupture disk but can be opened at any time by dropping a ball into the joint locator. The electronic circuit can be configured to provide a selected one of a plurality of time delays. A fixed test period is also provided in the circuit which delays activation of the time delay so that the joint locator may be tested before it is run into the well. The electric circuit and power supply are provided in a removable case for easy replacement and reconfiguration.
