Abstract: A module and method for interconnecting integrated circuits. The module includes an insulative body that features conductive traces having differing resistivities associated therewith. To that end, the insulative body has, disposed therein, a conductive bond pad and a plurality of spaced apart conductive traces, one of which is in electrical communication with the bond pad, with each of the plurality of conductive traces are formed from a material having a resistivity associated therewith. The resistivity of the material from which one of the plurality of conductive traces is formed being greater than the resistivity of the material from which the remaining conductive traces are formed and defines a decoupling capacitor therebetween.

Abstract: A field emission source produces a charged particle beam that can be electrostatically aligned with the optical axis. Quadrupole (or higher multipole) centering electrodes approximately centered on the optical axis are placed between the emitter and the extraction electrode. By applying centering potentials of equal amplitude and opposite polarity on opposing elements of the centering electrodes, an electrostatic deflection field is created near the optical axis. The electrostatic deflection field aligns the charged particle beam with the optical axis thereby obviating the need to mechanically align the emitter with the optical axis. A second set of centering electrodes may be used to deflect the charged particle beam back and to ensure that the charged particle beam is parallel with the optical axis. Further, the extraction electrode may be split into a quadrupole arrangement with the extraction and centering potentials superimposed.

Abstract: A theft resistant valve cap including a liner adapted for threaded engagement with a standard pneumatic tire stem valve, a sleeve rotatably mounted with the liner to shroud it and an interlocking feature to selectively prevent axial displacement between the liner and the sleeve. The interlocking feature includes a screw threaded into an aperture in the sleeve, or other coupling device, and an annular channel on the liner, positioned to receive the screw. The annular channel has an upper surface, a lower surface and an inner surface disposed between the upper and lower surfaces. The screw is moved so that it extends into the channel resting proximate to the upper surface, but clear of both said lower and inner surfaces. The screw can be removed after the valve cap has been installed. In this fashion, the liner and the sleeve are in a fixed axial position with respect to each other; however, the rotatability of the sleeve with respect to the liner is maintained, preventing removal of the liner from the stem.

Abstract: A precision printing system uses multiple scan beams that an acousto-optic modulator (AOM) separately modulates. An array of optical elements such as dove prisms separately rotates each of the beams about a central ray of the beam to eliminate blurred edges, skew, and variations in line thickness caused by the direction of propagation of acoustic waves in the AOM being at an angle to a scan direction. In particular, the amount of rotation is selected so that in the final image the direction in which illumination progresses across a cross-section of a beam is in a direction opposite the scan direction. A method of making the array includes attaching rods to a flat, grinding or polishing the combination of the rods and flat to form three planar regions that correspond to facets on prisms. Removing the rods/prisms from the flat. Using photolithography and etching to form grooves in a substrate, and a mounting the rods/prisms in the grooves on the substrate.

Abstract: An apparatus for conducting aqueous liquid media includes a plurality of static mixers, a gas distributor assembly with a plurality of nozzles, at least one impeller having blades attached thereto and a plurality of static mixer assemblies having flow guide elbows and collectors. The static mixer assemblies are independently and separately mounted to orient to the current leaving the blade tips of the impeller. Swirlers are also described as being utilized in place of the static mixers.

Abstract: A theft resistant valve cap including a liner adapted for threaded engagement with a standard pneumatic tire stem valve, a sleeve rotatably mounted with the liner to shroud it and an interlocking feature to selectively prevent axial displacement between the liner and the sleeve. The liner includes a hollow body with first and second opposed ends that features shoulders positioned proximate to one of said opposed ends. The shoulders, when employed with the sleeve rotatably mounted with the liner to shroud it, facilitates restricting removal of the cap from the valve stem to authorized individuals, only. Specifically, an interlocking mechanism extends between the liner and the sleeve and limits axial movement therebetween, while allowing rotational movement. To remove the cap from the valve stem, a key is employed which forms an interference fit with the shoulders in the liner, once exposed.

Abstract: A system and method for efficiently interconnecting a plurality of ICs, thereby improving the electrical performance of the overall system while reducing contact degradation due to stress that results from differences in the coefficients of thermal expansion of the various components during thermal cycling.

Abstract: A cartridge holder for a ballistic impeller golf-club of the type having a piston and a explosive charge disposed within the head of the golf club. The piston is adapted to travel outwardly from the club head in response to a rapidly expanding gas produced by the explosive charge. A golf-ball, disposed proximate to the club, is struck by the piston, thereby causing the golf-ball to travel a predetermined distance. The cartridge holder is adapted to be rotatably disposed on the golf club to rotated about an axis of symmetry with a plurality of cartridges retained by the cartridge holder so as to produce a rapidly expanding gas along a direction transverse to the axis of symmetry.

The helical body includes a plurality of coils with one end of each of the cables being coupled to one of the plurality of coils. The attachment includes an elliptically shaped journal through which one of the plurality of coils passes, thereby pivotally attaching the cable thereto. In one embodiment, a threaded boss is disposed at each end of the helical body. The threaded boss has a plurality of recesses, each of which is adapted to receive on of the plurality of coils. In this fashion, the threaded boss threadably engages the helical body.

Abstract: A fluorescence imaging system that includes an objective that is both achromatic and has an external entrance pupil. The objective also serves as a condenser for the system which substantially reduces the system's cost and footprint. With the objective positioned above a sample so that they are in close proximity to one another, a laser directs a collimated beam of light to a scan device located at the objective entrance pupil. The scan device reflects, refracts, or diffracts the light through the lens to illuminate a spot on the sample's surface. The scan device illuminates a line or an area on the sample surface by varying the angle of laser light, in one or two dimensions, into the objective. The sample emits fluorescent light in response to the illumination. The fluorescence light is collected by the objective and passes through the system along the path of the illumination light.

Abstract: A hybrid fiber-composite centrifuge container having a cylindrical metal sleeve, with a smooth inner surface permanently coupled to the fiber reinforced base. The reinforced base has an open end, a closed end and a cylindrical wall extending between the closed and open ends, with the metal sleeve coupled to the cylindrical wall proximate to the open end forming a sleeve-base interface. The base is formed from a plurality of layers of fiber material wound helically and circumferentially about the axis of the base. Among the plurality of layers of fiber material is a lane-change feature which provides a uniform outer diameter to the cylindrical wall that is coextensive with the interface. The uniform outer diameter helps prevent uncoiling of the plurality of layers of fiber material during centrifugation.

Abstract: A hydraulic lifting device, such as a forklift, is provided and is capable of dynamically measuring the weight of a load being lifted. A plurality of pressure measurements are taken during the lift for a period of time, which are stored in memory. A computer program is operated on by a microprocessor to process the pressure measurements to filter unwanted signals associated with vibration and other mechanical disturbances. The pressure samples processed by the computer program correspond to a portion of the lift during which acceleration of the forks has ceased, allowing a closer correspondence between the weight lifted and the pressure of the hydraulic fluid sensed.
