Abstract: A system for securely maintaining a high voltage cable within an electrical device, such as an x-ray tube, is disclosed. The system is useful for ensuring a close fit between an x-ray tube cathode insulator and the high voltage cable assembly disposed therein, thereby reducing the chances for damaging electrical arcing to occur. A high voltage cable assembly and clamp body generally comprise the system. The high voltage cable comprises two sections disposed at a right angle with respect to one another. One section defines a cavity for receiving a plunger/spring assembly housed within the clamp body. The plunger/spring assembly compresses and expands in response to the thermal expansion and contraction of the high voltage cable assembly during tube operation. A calibration window and adjustment screws are provided with the clamp body to enable a technician to readily determine and adjust the level of compressive force imparted by the system.

Abstract: A method for dynamically defining traffic lanes in a traffic monitoring system is presented. A traffic system sensor detects vehicles passing within the field of view and process the data into an estimation of the position of each of the detected vehicles. The positions are defined and recorded for use in a probability density function estimation. The traffic lane positions are defined such that further detection of vehicles may be assigned to a particular traffic lane without requiring manual set-up and definition of the traffic lane boundaries. The traffic lane boundaries may change or migrate based upon modification of traffic paths due to construction, weather, lane re-assignments and the like.

Abstract: A method for depositing an aluminum film limits the growth of voids and notches in the aluminum film and forms and aluminum film with a reduced amount of voids and notches. The first step of the method is to form an underlying layer upon which is deposited an aluminum film having a first thickness. The surface of the aluminum film is then exposed to a passivation species which coats the aluminum grains and precipitates at the grain boundaries so as to prevent grain movement. The exposure of the aluminum film to the passivation species reduces void formation and coalescence of the voids. An aluminum layer having a second thickness is then deposited over the initially deposited aluminum layer. In a second embodiment of the invention, the passivation species is deposited with MOCVD and to form an electromigration-resistant alloy. A third embodiment involves multiple depositions of aluminum, with exposure to a passivation species conducted after each deposition.

Abstract: The present invention is a technique for doing an asynchronous, breadth-first expansion of e-mail distribution lists, while being able to control the amount of resources needed to complete the expansion operation. The breadth first DL expansion technique described here correctly handles circular references while expanding distribution lists asynchronously, in a breadth-first fashion, and without requiring large amount of resources. The present invention provides a mechanism to control how many lookup requests are performed in parallel and the maximum amount of memory resources required to complete the DL expansion.

Abstract: Disclosed is a process of using undoped silicon dioxide as an etch mask for selectively etching doped silicon dioxide for forming a designated topographical structure. In one embodiment, a doped silicon dioxide layer is formed over a semiconductor substrate. An undoped silicon dioxide layer is formed and patterned over the doped silicon dioxide layer. Doped silicon dioxide is selectively removed from the doped silicon dioxide layer through the pattern by use of a plasma etch or another suitable etch that removes doped silicon dioxide at a rate greater than that of undoped silicon dioxide. The process may be used to form contacts to the semiconductor substrate. The process may also be used to form a structure with a lower and an upper series of parallel gate stacks, where the gate stacks have upper surfaces consisting essentially of undoped silicon dioxide.

Abstract: An integrated modular plug receptacle package is disclosed wherein one or more modular plug receptacles, or jacks, are defined by bringing two or more PC cards into operable communication, such as within the card slot cavity of a portable computer, for instance.

Abstract: A guidewire holder is provided that stores a coiled guidewire substantially immersed in a storage fluid and allows for a facilitated retrieval of the guidewire. The guidewire holder is generally configured as a shallow pan in a circular shape with an outer periphery to retain the coiled guidewire. The outer periphery includes a concave inner wall and a set of ribs that generally retain the coiled guidewire on the outer periphery. An access area is provided to suspend a portion of the guidewire away from the outer periphery to enable a medical practitioner to reach into the guidewire holder and grasp a portion of the guidewire in order to easily extract the coiled guidewire from the holder. An inner periphery reduces the amount of storage fluid needed to immerse the guidewire and is used in combination with the outer periphery to provide a location for comfortably holding the guidewire holder. Multiple holders may be coupled together so as to be stacked on top of each other.

Abstract: A vector network analyzer using sliding correlator techniques and multi-user detection techniques. The sliding correlator technique is based on the time domain sliding effect caused by a small clock frequency offset in the pseudo random code generators of a transmitter and a receiver. A time scaled version of the impulse response of the device under test can be obtained from the time domain slided pseudo random code signals by using a correlator. A multi-user detection method is introduced using two uncorrelated pseudo random codes. One of the uncorrelated pseudo random codes measures the D.U.T. and another code is a reference channel. These codes can be demodulated and despread with one receiver module. A Fast Fourier Transform of the measured impulse response is the frequency response of the measured signal.

Abstract: A color shifting multilayer interference film is provided which may be used to produce foils or flakes for use in pigment compositions and colorants having color shifting properties. The flakes can be interspersed into a pigment medium to form paints, inks, or cosmetic preparations which can subsequently be applied to objects, papers, or people. Three and five layer designs of the interference film include alternating layers of a dielectric material and carbon in various configurations. The dielectric layers are formed to have an optical thickness at a design wavelength that provides a color shift as the angle of incident light or viewing angle changes.

Abstract: Surface modifications of a mold used during semiconductor device fabrication provide non-stick characteristics and a mold surface that is resistant to abrasion or wear. Such surface modifications are particularly useful in a mold having a quartz planar surface adapted to contact a photocurable polymer material applied to a semiconductor wafer surface during a fabrication process. The planar surface of the mold is capable of allowing transmission of ultraviolet light therethrough to cure the polymer material. A non-stick film is formed on the planar surface of the mold by a coating or deposition process in order to modify the mold surface. The non-stick film can be formed of a fluoroalkylsilane compound. or a hard material such as diamond or diamond-like carbon. The non-stick film of diamond or diamond-like carbon provides protection against abrasion or wear on the planar surface of the mold.
