Abstract: The support prop consists of an outer tube (12) with an open flared mouth (14) into which a plunger (16) projects. A deforming ring (18) in use engages the plunger and is initially located within the flared mouth of the outer tube. A chamber (26) is provided within the prop into which fluid under pressure can be introduced through an inlet (28) to the chamber to locate the prop between two surfaces by displacing the plunger relative to the outer tube. A seal (24) is located within the chamber to prevent the fluid from escaping between the plunger and the bore of the outer tube.

Title: Switching circuit and charge transfer device using same
Inventor: MAKI YASUHITO
IPC: H04N5/335
Filed: 1996-03-12
Granted: 2006-10-03
Abstract: A switching circuit comprising a means for holding a signal or a DC component thereof, and a switching transistor for driving the holding means, wherein another means is included for shaping the trailing edge to be more obtuse in the fall of a driving pulse applied to a gate of the switching transistor. There is also disclosed a charge transfer device comprising a charge transferrer for transferring a signal charge, a charge-voltage converter for converting the transferred signal charge into a proportional voltage, and a driver for supplying a reset pulse to the charge-voltage converter so as to reset the capacitance thereof to a predetermined potential, wherein another a means is incorporated in the driver for shaping the trailing edge to be more obtuse in the fall of the reset pulse. Since the trailing edge of the reset pulse at the time of turning off the reset is rendered more obtuse, it becomes possible to reduce the coupling portion of the output waveform where the potential of a floating diffusion or a floating gate is varied by the capacitive coupling which is derived from the parasitic capacitance between a reset drain and a reset gate.

Title: Electronic television program guide
Inventor: RZESZEWSKI THEODORE S
IPC: H04N5/445
Filed: 1996-03-29
Granted: 2000-07-18
Abstract: A method and device for receiving and storing an electronic television (TV) program guide. In a satellite, cable or broadcast TV system, electronic TV program guides may be coded into the video signals received by the TV receiver. Many currently available TV receivers also allow users to program a list of "select-channels." When the receiver is in its select-channel mode, the receiver only tunes to the channels the user stored in the list of select channels. The present invention limits the memory and processing power required to store an electronic TV program guide by only storing program guide information associated with the channels stored by the user in connection with the select-channels function of the receiver. In receivers having a second tuner, the second tuner may be used to automatically update the stored program guide.

Abstract: A spatial light modulator of the DMD type having increased performance parameters. A pixel mirror is supported by a yoke whereby electrostatic attraction forces are generated between several structures. First, between the elevated mirror and an elevated address electrode. Second, between the yoke and an underlying address electrode. The pixel achieves high address torque, high latching torques, high reset forces, and greater address margins over previous generation devices. The proximity of the yoke over the substrate address electrodes realizes large attraction forces whereby the pixel is less susceptible to address upset, requires lower reset voltages and provides higher switching speeds.

Title: System for simplifying the implementation of specified functions
Inventor: DOMANIK RICHARD A
IPC: G06F3/033
Filed: 1996-09-13
Granted: 2008-08-05
Abstract: A machine, method and medium for implementing functions using an input device in a manner that enhances efficient operation of a mechanism capable of operating in at least two states. The functions are implemented via a convenient input device, such as a mouse. One or more specified actuators of the input device implement a given function when the mechanism is in a first state, while at least one of those actuators implements a different function when the mechanism is in a second state. In embodiments of the present invention contemplating that the mechanism is a microscope system, two states in which the microscope system is envisioned to operate are a scan state and a pause state. The scan state allows the microscope system to execute a pre-defined scan sequence, while the pause state allows the microscope system to pause from that sequence.

The distal and proximal components may further include means for selectively combining the proximal and distal components to form a femoral trial prosthesis that corresponds to an available prosthetic femoral implant. The dimensions of the distal and proximal components may be undersized when compared to the corresponding regions of the prosthetic femoral implant.

Abstract: L'invention est une méthode de géolocalisation des terminaux mobiles d'un système de télécommunication à satellites. Ce système prend en charge une première et une seconde liaison de communication directe allant d'une première et d'une seconde station terrienne à un terminal mobile commun en passant par un premier et un second satellite. Dans la méthode de l'invention, les signaux transmis par la première et la seconde station terrienne via la première et la seconde liaison de communication directe sont reçues au terminal mobile et des données de synchronisation différentielles sont extraites des signaux reçus. Ces données peuvent comprendre des données servant à maintenir la synchronisation de la première et de la seconde liaison de communication au terminal mobile. Celui-ci transmet les données de synchronisation différentielles à la première station terrienne via la liaison de retour. La première station terrienne reçoit les signaux de communication du terminal mobile et, en se basant sur ces signaux, calcule les données de synchronisation de la liaison de retour. Elle calcule de plus au moins une première et une seconde ligne de géolocalisation sur lesquelles se trouve le terminal mobile en se basant sur les données de synchronisation de la liaison de retour et les données de synchronisation différentielles reçues du terminal mobile. La première et la seconde ligne de géolocalisation ont un point d'intersection qui correspond à la position du terminal mobile.

Abstract: The dissolution at pH 6.5 of prednisolone metasulphobenzoate or a pharmacologically acceptable salt thereof from a non-disintegratable solid enteric composition comprising the prednisolone metasulphobenzoate in an excipient matrix is increased by the presence in the matrix of a rheological modifying agent, especially croscarmellose, in an amount of at least 5 percent by weight of the composition but insufficient to cause disintegration. Preferably the composition is in the form of pellet s coated with an enteric coating which is substantially insoluble below pH 7 and contained in a capsule or tablet coated with an enteric coati ng which is soluble at a pH in the range pH 5.5 to pH 7. The coated capsules and tablets are for use in the treatment of inflammatory bow el disease, especially ulcerative colitis and Crohn's disease.
