Abstract: A lock assembly includes a cylindrical key plug (12) with a key slot (16) and a shell (10) surrounding the plug (12). A first locking mechanism is provided by split top pins (20) projecting across the shear surface inter facebetween the plug (12) and the shell (10) and positio ned to align the split in the split top pins (20) with the shear surface by notches of varying height located along the top of a key (14). Second and third locking mechanisms are located in the plug (12) and include a locking bar (32) that projects in to alocking groove (36) in the shell (10) in the locked position. The locking bar (32) has an offset ridge (44) along an upper edge that prevents the locking bar (32) from moving to an unlocked position unless side pins (46) having recesses (48) adapted to receive the ridge (44) are positioned by depression s (54) along the side of the key (14) to align the recesses (48) with the ridg e (44). The lock can be rekeyed by reversing the locking bar (32).

Title: Auto-calibrated digital-to-analog converter for a video display
Inventor: DINGWALL ANDREW GORDON FRANCIS
IPC: H04N5/66
Filed: 1996-11-28
Granted: 2006-06-13
Abstract: Each of N current summation type digital-to-analog (D/A) converters of a liquid crystal display driver generates an analog signal which provides pixel video information. In an error sampling interval of the D/A converter, the output signal of the D/A converter developed when the data to be converted is at full scale is compared in a comparator with a reference voltage. An error signal is sampled and is used for varying a control voltage developed in a capacitor. The control voltage controls the current sources of the D/A converter in a current mirror manner. The reference voltage is coupled in common to each of the comparators of the D/A converters. In this way, matching among the D/A converters and the accuracy of each are enhanced.

Abstract: A cup dispenser is disclosed including a housing having an open end and a closed end defining a cup receiving cavity, a cup support reciprocally positioned within the cup receiving cavity for supporting at least one cup received in the cup receiving cavity and a spring for biasing the cup support towards the open end of the cup receiving cavity thereby projecting at least a portion of the cup from the housing. The cup dispenser further includes a guide for guiding the cup support within the housing with a guide including axially extending substantially diametrically opposed rails and a cup restraint for restraining outward movement of the cup within the cavity and a stop position adjacent the guide for stopping outward movement of the cup support. The stop includes at least one circumferentially extending contact surface which contacts a surface of the cup support in order to stop outward movement of the cup support. Additionally, the cup restraint includes at least one substantially radially inwardly extending detent positioned adjacent the open end of the housing as well as an auxiliary cup restraint positioned adjacent the first cup restraint for staging of the next cup to be dispensed. This auxiliary cup restraint prevents dispensing of more than one cup at a time by relieving the pressure of the total stack load and spring pressure on the cupto be dispensed. The auxiliary cup restraint includes at least one axially extending fin with the fin having an axial length which is less that the axial length of the diametrically opposed rails. The fins further include cup stacks stabilizers which stabilizes the stack of cups adjacent the open end of the housing. Further, an annular recess is formed in the housing extending about an outer circumference thereof and adjacent the open end of the housing.

Abstract: In a borehole logging tool, a hot wire anemometer measures fluid flow entering or exiting the borehole (16) at the wall of the borehole. The logging tool has open aperture sensing pads (14, 15) mounted onto arms (12, 13) placed in mechanical contact with the wall that place the sensor pads at the wall surface. The sensor pads have an open aperture across their central area to permit fluid flow therethrough in such a manner that provides minimum disruption of flow between the borehole and the surrounding earth formations about the borehole being logged. Other sensors mounted on the sensor pad measure parameters such as fluid type, flowrate or fluid flow direction, as well as fluid properties including capacitance, dielectric constant and temperature of the passing fluid; or contain a shield attached at the end of the sensor pad upstream of the fluid flowing in the borehole center so as to minimize effects from fluids flowing in the center of the borehole.

Title: Method and system for determining and or using illumination maps in rendering images
Inventor: LAFERRIERE ALAIN M
IPC: G06T15/50
Filed: 1998-01-20
Granted: 2006-06-13
Abstract: A system and method of determining, and subsequently using in a rendering engine, an illumination map. The illumination map is employed by the rendering engine to avoid having to calculate the contributions of lights in the scene during rendering, thus reducing the rendering time. In one embodiment, the system and method is used to determine the illumination values from the contribution of one or more lights to one or more texture mapped objects. This illumination map can either be stored independently of the texture picture to be mapped or can be combined with the texture picture to obtain an illuminated texture picture for subsequent rendering independent of the light sources. In another embodiment, the present invention is used to determine the illumination values for one or more objects represented by a polygon mesh. This illumination map can be stored independent of the material and color of the object or can be combined with the color and material information and stored in the object definition. In either of these cases, this illumination map represents the illumination values at the vertices of the polygons, the rendering engine and/or hardware linearly interpolating the remainder of the rendering information for each polygon. The illumination values can be determined either by summing the contribution of the lights in a scene at points of interest or by evaluating the entire shade tree defined for the scene at those points of interest. In this latter case, the contributions of reflections, refractions, transparencies and any procedural functions defined for the scene are considered in determining the illumination values. Evaluation of the entire shade tree also allows other options, such as the ability to generate 2D textures from procedural 3D textures or to generate a texture that contains the result of a blending between multiple textures.

Granted: 2008-01-22
Abstract: A positive displacement gear pump useful for pumping hydraulic fluid includes a drive gear and an idler gear. In a first embodiment, the drive gear has symmetrical teeth, whereas the idler gear has asymmetrical teeth. The asymmetrical teeth of the idler gear include working surfaces which have a profile corresponding to the profile of the working and non-working surfaces of the drive gear, but have a non-working surface which has been relieved so as to be substantially flat. Consequently, in the zone of the pump where the gears mesh, a large backlash is created which substantially prevents bubble formation. In a second embodiment, the drive gear, as well as the idler gear, have non-contact surfaces which are substantially flat to create even a larger backlash for relieving cavitation when the teeth are made wider in the axial direction. By preventing bubble formation, cavitation which occurs at high pump speeds is substantially eliminated, thus avoiding pump damage which results from cavitation.

Title: Hydraulic control valve system with non-shuttle pressure compensator
Inventor: WILKE RAUD A
IPC: F15B11/16
Filed: 1998-10-20
Granted: 2003-03-18
Abstract: An improved pressure-compensated hydraulic system for feeding hydraulic fluid from a variable displacement pump to multiple hydraulic actuators.  A separate valve section controls the fluid flow between the pump and a different actuator.  Each valve section has a pressure compensating valve with a valve member and poppet within a bore and biased apart by a spring.  The poppet acts as a check valve which prevents fluid flow from the actuator through the valve section to the pump when the back pressure from the load exceeds the pump supply pressure.  A pressure differential between the load-dependent pressure and the actuator pressure determines a position of the valve member which controls the pressure applied to the pump pressure control input.
