Abstract: A novel rotary table is secured to the top of a well's BOP simplifying the making up of sectional tubing joints used in some aspects of operations with coiled tubing. The rotary table comprises top a bottom stationary housing affixed to the BOP, a top housing supported on the bottom housing by an annular bearing, a split clamp to transferring the weight of the tubing to the top housing and seals between the top and bottom housings and between the top housing and the tubing. More preferably, a coiled tubing rig is provided having a frame, a tiltable mast, an injector reel, a tubing straightener and a jib crane in combination with the rotary table for increased functionality including drilling surface hole using coiled tubing. The mast tilts between two positions, either aligning coiled tubing and injector with the BOP or aligning a jib crane and tubing elevators for manipulating sectional tubing including BHA onto and through the rotary table.

Abstract: A blowout preventer (BOP) protector is adapted to support a tubing string in a well bore so that the tubing string is directly accessible during a well treatment to stimulate production. The BOP protector includes a mandrel having an annular sealing body bonded to its bottom end for sealing engagement with a bit guide that protects a top of a casing of a well to be stimulated. The mandrel is connected at its top end to a fracturing head, including a central passage and radial passages in fluid communication with the central passage.      The mandrel is locked in a fixed position by a lockdown mechanism that prevents upward movement induced by fluid pressures in the wellbore and downward movement induced by the weight of a tubing string supported at a top of the fracturing head by a tubing adapter. The advantages are that the BOP protector permits access to the tubing string during well treatment and enables an operator to move the tubing string up and down or run coil tubing into or out of the wellbore without removing the tool.      This reduces operation costs, saves time and enables many new procedures that were previously impossible or impractical.

Abstract: The present invention provides methods of forming mud motors. In one method, rollers are urgingly stroked against a tubular member having a mandrel therein that has an outer profile which is the inverse of the desired profile of the stator. In another method, rollers are urged and rotated radially on the tubular member with the mandrel disposed in the tubular member. In yet another method, dies are pressed against the tubular member having a mandrel with a desired outer profile. In another method, a molten metal is deposited over a mandrel with an outer lobed surface that is substantially the inverse of the desired inner profile of the stator housing. The mandrel is then removed, leaving a metallic longitudinal member having an inner profile defined by the outer profile of the mandrel. The mandrel may also be a preformed liner of desired thickness having an inner and outer lobed surface.  In each of these methods, the inner surface of the resulting member has the profile defined by the outer profile of the mandrel. The inner surface of the resulting member then may be coated or lined with a suitable material such as an elastomer or a ceramic. The stator inner surface may also be metallic. A suitable rotor is then disposed in the stator to form the drilling motor.

Title: Improvements in or relating to radar systems
Inventor: BAKER JONATHAN HOWARD
IPC: G01S13/524
Filed: 1999-02-15
Granted: 2007-10-16
Abstract: In a radar system it is necessary to dis-tinguish signals reflected from wanted targets such as aircraft from those reflected from fixed terrain features, known as clutter. The clut-ter signals can in some cases be significantly stronger than the wanted signals. One method for dealing with land clutter is the use of a high resolution clutter map. The area around the radar is considered to be divided into cells, and an array of background signal estimates is maintained for these cells. Whenever a signal is received by the radar, it is compared with the stored background level for the cell it oc-cupies, and a detection is only reported if the signal exceeds the background by a pro-set threshold. Received signals are also used to modify the stored background levels so that the clutter map adapts to the reflections from clutter which are present over long periods. Clutter maps have so far only been used successfully for radars at fixed locations. In the case of a shipborne radar near land, a conventional clutter map will not work well.  This is because as the ship moves, the positions of land scatterers relative to the ship will not be fixed. Individual terrain features will therefore be moved from one clutter map cell to another.  In the cell into which a strong scatterer moves, the land clutter reflections will be reported as targets until the stored background has had time to adapt to the new higher level. Similarly, in the cell which the scatterer has left, the stored background level will be higher than necessary, and may cause actual targets to be suppressed until it has had time to adapt to the new lower clutter level. The method of operating a radar system in accordance with the present invention provides compensation of ship movement so that fixed terrain features always stay within the same clutter map cell, periodically re-centering the clutter map so that its origin of co-ordinates does not depart too far from the actual ship position. Two separate clutter maps are used so that one can be re-centered and initialised (filled with suitable background estimates) whilst the other is in use for determining radar detections. A method for accelerating the initialisation time so that re-centering can be achieved sufficiently often during rapid movement is provided, and the updating of cell background levels is combined with the detection process in order to streamline the process and reduce computational load.

Title: Device security mechanism based on registered passwords
Inventor: THOMPSON MELINDA M
IPC: G06F1/00
Filed: 2000-11-17
Granted: 2005-01-11
Abstract: The BIOS device or some other secure store of a portable computer or other valuable device stores a password-based security program, an encrypted password, and an encryption key. When the PC is booted, the security program executes first and prompts the user for a password, encrypts it with the stored key, and compares it with the stored password. If the passwords do not match, boot is aborted and the PC is disabled. Only if the passwords do match is boot continued and use of the PC enabled. If this security measure is advertised, theft of the PC is deterred because of the difficulty of accessing or bypassing the password and the security program in the BIOS device. The encrypted password is also registered with a remote trusted certificate authority or is stored on a local external storage device.  To establish or change the password, a communication connection is established from the PC to the TCA or storage device. If a password already exists in the PC, it is compared against the password stored by the TCA or the storage device. If they match, or if a password does not yet exist, the user is prompted for a new password, which is then encrypted and stored in both the BIOS device and the TCA or storage device. The password is also available for retrieval from the TCA or storage device in case the user forgets it.

Title: Estimation of cardiac ejection fraction and end diastolic volume
Inventor: ROTELIUK LUCHY D
IPC: A61B5/0275
Filed: 2000-12-01
Granted: 2011-03-15
Abstract: The invention estimates a cardiac performance value such as cardiac output (CO) and cardiac ejection fraction (EF) by sensing a downstream indicator concentration signal y(t) that corresponds to an indicator (preferably heat) signal x(t) injected upstream in a patient's blood channel. The signal x(t) is preferably generated as a series of alternating transitions between a high state and a low state, such as a PRBS signal. The signal y(t) is then divided into at least one sub-signal that is synchronous with x(t). A decay parameter .tau. that minimizes a cost function that includes a time-domain channel relaxation model is then calculated. The cardiac performance value is then calculated based on this value for .tau.. For each transition of the injected indicator signal, a corre-sponding segment of the indicator concentration signal is preferably isolated, and a segment relaxation parameter is then calculated. The decay parameter .tau. is then estimated as a predetermined function of the segment relaxation parameters. In embodiments of the invention in which x(t) is periodic, the invention also generates estimates of .tau. by finding the minimum of a cost function between a model of the channel and an average of several cycles of y(t), each corresponding to one period of x(t).
