Title: Radar
Inventor: GELLEKINK BERNARD
IPC: G01S7/02
Filed: 1994-09-01
Granted: 2005-06-21
Abstract: Radar comprenant une antenne réseau à commande de phase (1) pourvue d'un grand nombre de modules émetteurs et récepterus (2), une unité de commande (3) et un processeur vidéo (4). Pour chaque direction d'azimut-élévation, l'unité de commande génère un certain nombre de salves d'impulsions, dont chacune présente de légères différences de fréquence porteuse. Pour chaque salve d'impulsions, le processeur vidéo (4) détermine un spectre Doppler et compare les spectres successifs. En raison des différences de fréquence, les échos parasites ne subiront pratiquement pas de décalage, tandis que les cibles sujettes à un repli dans le domaine de fréquence subiront un décalage considérable. Un seuil fondé sur un spectre moyen permet ainsi d'effectuer la détection.

Abstract: A method for transmitting a biolog-ically active material to a cell is provided. The method involves encapsulating the ma-terial to be transmitted in a pancilamel-lar non-phospholipid carrier vesicle which does not lyse cells upon fusion with cells, delivering the carrier vesicle to a location proximate to the cell, allowing the non-phospholipid bilayer of the carrier vesicle to fuse with the membrane of the cell and al-lowing the encapsulated material to diffuse into the cell. The method can be used to transmit a variety of biologically active ma-terials to cells either in vivo or in vivo. The method provides a means for transmitting a biologically active material directly to the cytoplasm of a cell. Upon fusion with a cell, material associated with the bilayers of the non-phospholipid vesicle becomes in-corporated into the outer membrane of the cell. Accordingly, a method for transmit-ting bilayer-associated material to a cell is also provided.

Abstract: Video signals to be displayed are applied via a video driver amplifier (50) to the cathode electrode (32, 34, 36) of a kinescope (30). A beam current sensor (56), also coupled to the cathode electrode (32, 34, 36), provides a beam current indicating signal (S6). An AKB regulator (60), responsive to the beam current indicating signal (S6), supplies a black level correction signal (Ia) to the driver amplifier (50) for regulating the black level of images displayed by the kinescope (30). A screen grid supply system (70, 90) is provided for controlling the G-2 (screen grid) voltage of the kinescope (30) as a predetermined function of the black level correction signal (Ia) thereby forming with the AKB regulator (60) a dual feedback loop for providing black level regulation by both the driver amplifier (50) and the screen grid (G2) thereby maximizing or extending the overall black level control range.  Consequently, the high voltage screen control potentiometer (97) normally required for setting screen grid bias may be completely eliminated if desired, or, in applications where it is retained, no adjustments are required subsequent to an initial adjustement.

Abstract: The present invention relates to an improved method and device for aiming and firing a rifle-mounted grenade launcher without having to approximate the range of a target and then manually adjust the position of subsequently fired grenades. The grenadier initiates the process by pointing the grenade launcher at the target.  The range and azimuth of the target are determined by a microprocessor controlled laser range finder/digital compass combination.  A ballistic solution is calculated by the microprocessor and the superelevation required to place the grenade on target is displayed on one of several video displays.  The grenadier then uses the vertical angle measurement capability of the laser range finder/digital compass assembly to rotate the grenade launcher to the proper angle while maintaining the proper azimuth.   The grenade is then fired on target.   The present method and associated hardware may be used as one component of a fully integrated, multi-functional, soldier-centered, computer-enhanced warfare system.

Title: Platelet blockade assay
Inventor: COLLER BARRY S
IPC: G01N33/86
Filed: 1995-09-20
Granted: 2004-05-18
Abstract: The present invention is an assay for determining glycoprotein IIb/IIIa receptor blockade in whole blood. Agglutinization of small polymeric beads coated with a glycoprotein IIb/IIIa ligand such as fibrinoge n results when the beads are contacted with whole blood containing platelets with glycoprotein IIb/IIIa receptors that are not blocked. Failure to agglutinate indicates that blockade of the GPIIb/IIIa receptors has been achieved. In a preferred embodiment, the addition of a thrombin receptor activator results in an assay that is rapid and convenient enough to be performed at bedside and that results in agglutinati on of the small polymeric beads within a convenient, known period of time if the glycoprotein IIb/IIIa receptors are not blocked.</SDOA B>

Title: Creating proxies for distribution of beans and event objects
Inventor: CHAN VICTOR SHIH-CHUAN
IPC: G06F9/46
Filed: 1997-07-17
Granted: 2003-12-23
Abstract: The invention provides a mechanism for distributing objects from a object oriented framework that permits method invocation and state information notification, such as event notification in a JavaBeans software component model. A code generation tool generates code from an existing server object that contains only application domain specific logic, to support deployment of the server object on a remote machine in a distributed application. The generated code includes a proxy class to reside locally with a client program that might invoke methods on the server object or receive notification of state information (events) from the server object, and a proxy class to be remotely deployed with the server object. The proxies created provide all the middleware specific logics. More importantly, the proxy on the client side contains all of the public methods, properties and event interfaces of the server object, so that a client program using this proxy can invoke the server object's methods and register to receive notification of state information on the proxy as if it were interacting locally with the server object. A proxy on the server side communicates the client program's method invocations and registrations to receive event notifications to the server object as if this proxy were a local client. When an event notification is issued by the server object, it is received by the proxy on the client side which transmits the notification through the middleware of the distributed application to the proxy on the client side. The proxy on the client side overrides the identification of the source of the notification, substituting itself, to receive any requests for data on the state information from the client program, but then delegates such requests to the object containing the state information to be fulfilled.

Abstract: In a PLL circuit used in a display monitor, it is made possible to design a PLL circuit using a VCO of excellent frequency stability. In this PLL circuit, low jitter of display monitor is realized without having to consider variations of oscillation frequency of VCO practically. It solves the problems of effects of variations of oscillation frequency on the cost and productivity.  This PLL circuit preliminarily detects the range of frequency divid-ing range of the frequency dividing ratio of the dividing circuit capable of locking the PLL circuit with respect to the input signal with known frequency by frequency detecting means. The detected frequency data is stored in the memory. On the basis of the frequency data, the frequency dividing ratio of the dividing circuit is set. By this setting, even if different input signals are entered, the VCO operates at a frequency near the center of the variable range of the oscillation frequency.

Title: Differential satellite positioning system ground station with integrity monitoring
Inventor: BRENNER MATS A
IPC: G01C21/00
Filed: 1996-06-24
Granted: 2005-08-02
Abstract: In the present invention, a plurality of DGPS receivers are employed to determine receiver-satellite-specific differential correction values. In turn, satellite-specific differential correction values are determined as an average of the individual receiver-satellite-specific differential correction values for each of the tracked satellites. A discriminator is employed for determining a receiver-satellite-specific discriminant which may be sampled and subsequent determination of a receiver-satellite-specific statistical value thereof. The receiver-satellite-specific statistical values may then be employed for determination of a Detection Threshold value and other integrity information associated with each of the satellite- specific differential correction values. The ground station further includes a means for communicating the satellite-specific differential correction values and integrity information associated therewith to a DGPS airborne receiver. A DGPS airborne system in accordance with the present invention is configured to include a mechanization for receiving the satellite-specific differential correction values and integrity information associated therewith. An airborne integrity monitoring system may then be employed to derive particular integrity limit values associated with the DGPS derived position for pilot awareness as to whether or not the pilot should rely upon the DGPS solution for a precision landing.

Abstract: Improved methods and apparatus for placing and cementing a casing string in a horizontal well bore section are provided.          A float shoe is attached to the end of the casing string and a float collar is connected in the casing string for trapping air in a first portion of the casing string thereby causing it to be buoyed up during placement by drilling fluid contained in the well bore.  A selectively openable and releasable closed baffle assembly is connected within the casing string for trapping air or a low density fluid in a second portion of the casing string thereby causing it to also be buoyed up by drilling fluid in the well  bore.   The buoying up  of  the  casing  string reduces placement drag and consequent compressive loading on the casing string.  After placement, the closed baffle means is opened to allow fluid circulation and conditioning of the annulus.   A bottom cementing plug is then landed on the baffle assembly and the baffle assembly is released and moved to the float collar. A cement slurry is thereafter placed in the annulus and allowed to set therein.

Title: Medical valve with fluid escape space
Inventor: LOPEZ GEORGE A
IPC: A61M39/10
Filed: 1996-12-16
Granted: 2007-10-30
Abstract: A medical valve has a body which includes a wall structure defining an internal cavity hav-ing an inside and an outside. The body also has a proximal end and a distal end. The proximal end has an opening sufficiently large to receive a tip of a delivery end of a medical implement which transfers fluid through the deliv-ery end. The body has a fluid escape space in its wall struc-ture.   The valve also has a spike with a tip and at least one hole located at or near the tip. The spike has a passageway in com-munication with the hole that al-lows fluid to flow through the spike. A resilient seal in the cav-ity surrounds the spike. This seal is adapted to be moved into a compressed state upon insertion of the tip of the medical imple-ment into the opening. The seal is sufficiently resilient to return to a decompressed state upon re-moval of the tip of the medical implement from the opening. The fluid escape space is in fluid communication with the outside of the cavity when the seal is in its compressed state.

Title: Method and system for simultaneous variable-width bus access in a multiprocessor system
Inventor: TRAN CANG N
IPC: G06F13/364
Filed: 1998-08-14
Granted: 2002-08-06
Abstract: A method and system for enhanced bus access in a multiprocessor system having multiprocessors coupled to a system memory via a common wide bus. The common wide bus is subdivided into multiple sub-buses which may be accessed individually or in groups by a selected processor, or individual sub-buses may be accessed by multiple processors simultaneously. In response to one or more pending transactions, each processor outputs a request to bus arbitration logic for a maximum-permitted number of sub-buses. If the number of sub-buses granted to a particular processor equals the number of pending transactions at that processor, all pending transactions are performed in parallel on separate sub-buses. If the number of sub-buses granted is less than the number of pending transactions, pending transactions are performed in a priority order. Finally, if the number of granted sub-buses is greater than the number of pending transactions, selected transactions are performed over multiple sub-buses in parallel, greatly enhancing the speed of those transactions.
