Title: Multilayer microstructures and laser based method for precision and reduced damage patterning of such structures
Inventor: DUBOWSKI JAN J
IPC: B23K26/40
Filed: 2002-04-12
Abstract: Many integrated circuits require a multilayer structure which contains layer of an organic or polymeric material with a patterned metallic layer on it. Laser patterning has many favourable characteristics but it also damages the organic or polymeric material. A novel method is disclosed that makes possible laser patterning of conductive metal electrode deposited on top of an organic and/or polymeric material without significant ablation of the organic and/or polymeric material. The method can achieve higher patterning resolution, resulting in higher quality integrated circuits. The method is based on the application of a thin coating of an inexpensive anti-reflector deposited on top of the desired metal electrode which in turn lies on the organic and/or polymeric material. The thin anti-reflecting coating allows the use of a lower fluence laser for ablation of metal layer without damaging the underlying organic and/or polymeric material.

Title: System and method for adaptive drug delivery
Inventor: STRUYS MICHEL
IPC: A61M5/00
Filed: 2001-05-03
Abstract: A system and method for controlling the administration of medication to a patient utilizes adaptive feedback to achieve and maintain a target effect in said patient. A sensor package having one or more sensors is used to sense an attribute of the patient and to provide a parameter indicating the attribute being sensed. A medication delivery controller accepts one or more parameters from the sensor package and uses these parameters to determine the effect of a medication on a patient and the concentration level of medication that will achieve a desired effect. The medication delivery controller controls the medication delivery unit to deliver the medication at a rate determined to achieve said target concentration level of said medication in said patient. If the patient's response to a given medication changes as a result of external stimuli, the medication delivery controller can detect this change and determine a new concentration level of medication which will achieve the desired effect. The medication delivery controller can steer the medication delivery unit to administer an amount of medication to reach this new concentration level.

Title: Method and device for compensating firing errors and system computer for weapon system
Inventor: SCHNEIDER GABRIEL
IPC: F41A27/30
Filed: 2003-01-13
Abstract: A method and a device (20) are described for compensating firing errors of a gun having a weapon barrel (10.2). Firing errors, which are caused by static gun geometry errors, which influence the position of the weapon barrel (10.2) during aiming of the weapon barrel (10.2) at aiming values, are compensated.     For this purpose, the weapon barrel (10.2) is brought into measurement positions in steps by rotation around an axis. Using suitable devices of a measurement facility, an intended value, which describes the intended position of the weapon barrel (10.2), and an actual value, which describes the actual position of the weapon barrel (10.2), are detected at each measurement position. A difference between the actual value and the intended value, defined as an error value, is then calculated. Correction values are established from multiple error values of the measurement positions and the correction values are taken into consideration during later aiming of the weapon barrel (10.2).     The method and the device (20) are used for a weapon system (10) which has a system computer (10.4) for calculating aiming values for aiming a weapon barrel (10.2) of a gun (10.1) of the weapon system (10); the system computer (10.4) has a data input (24) for data which is made available, this data being intended far the purpose of being taken into consideration during the calculation of the aiming values, in order to compensate aiming errors, which are caused by static gun geometry errors and which influence the position of the weapon barrel (10.2).

Title: Method for evening tension in a twisted pair electric cable
Inventor: SMITH CHAD R
IPC: H02G7/04
Filed: 2003-02-07
Abstract: A method of evening the tension in the conductors of a twisted pair electric cable during the cable's installation comprising the step of pulling the cable through stringing rollers while attached to a tension evening device. That allows constant adjustment of the tension in each of the cable's conductors, which prevents an unwanted looping effect and eliminates the need to even the tension at the end of the installation process.   The tension evening device comprises a pull rope attached to a swivel that holds a sheave. The device is sized small enough so that it fits through the stringing rollers such that, during the installation of the cable, the entire tension evening device is pulled through.   The sheave includes a groove around its outside diameter in which a sheave rope is placed.   The ends of the sheave rope are attached to an end of each conductor. The tension in the conductors is maintained by the sheave and sheave rope which rotate in response to the tension or force applied by the conductors, providing greater slack to the higher tensioned conductor and exerting a greater pulling force on the lower tensioned conductor.

Title: Polycrystalline diamond with a surface depleted of catalyzing material
Inventor: GRIFFIN NIGEL DENNIS
IPC: E21B10/60
Filed: 2001-06-25
Abstract: The present invention provides a superhard polycrystalline diamond or diamond-like element with greatly improved resistance to thermal degradation without loss of impact strength. Collectively called PCD elements, these elements are formed with a binder-catalyzing material in a high-temperature, high-pressure process. The PCD element has a plurality of partially bonded diamond or diamond-like crystals forming at least one continuous diamond matrix, and the interstices among the diamond crystals forming at least one continuous interstitial matrix containing a catalyzing material. The element has a working surface and a body, where a portion of the interstitial matrix in the body adjacent to the working surface is substantially free of the catalyzing material, and the remaining interstitial matrix contains the catalyzing material. This translates to higher wear resistance in cutting applications, higher heat transfer capacity in heat sink applications, and has advantages in numerous other applications including hollow dies, indentors, tool mandrels, and wear elements.

Abstract: A data resource (22) specific to a pipe coupling (18) centrally positioned within the coupling (18), intermediate the coupling ends. Multiple couplings (18) are employed to connect together a string of well pipe (p). The data resource (22) is adapted to be deployed at the coupling center (J) in the space formed between the abutting ends of pipe (p) made up into the coupling (18). The data resource (22) provides information regarding the physical characteristics and locations of the coupling (18), the attached string pipe (p) or the environment within which the coupling (18) is disposed. The data resource (22) may be a read-only component or it may be a readable and writeable component. The resource (22) communicates with an instrument (I) movable through the pipe (p) and coupling (18). The data resource (22) may be removably positioned at the center of the coupling (18) or it may be permanently cemented in place. The data resource (22) may take on the form of an annular ring (10) with a crushable structure (26) and suitable recesses (21) for holding a data source (22) module. A circular communication antenna (23) may be carried in the ring (10). A preferred form of the data resource (22) is an externally threaded Teflon ring (10) equipped with axially extending resilient fingers (26). The resilient fingers (26) are deformable upon engagement with the rotating ends of the pipe (p) sections so that advancing the pipe (p) sections beyond their optimum depth into the coupling (18) deforms the fingers (26) without rotating and thus displacing the ring (10). The body (25) of the ring (10) remains in the gap between the pipe (p) and where it is protected from crushing.
