Title: System and method for managing device driver logical state information in an information handling system
Inventor: COOPER MICHAEL R
IPC: G06F9/445
Filed: 1998-03-09
Abstract: The present invention is directed to a system and method of managing logical device state information within an information handling system. Logical device state information is stored only once, by the information handling system. Device drivers do not need to maintain and store redundant copies of logical device state information. A device driver indicates whether or not it needs to have logical device state information passed to it. Before calling a device driver to handle a device function, the information handling system checks to determine whether or not the device driver has indicated that it needs logical device state information passed to it. If so, the information handling system passes the appropriate logical device state information to the device driver. For device functions which are not hooked by the device driver, the information handling system maintains the device state. System efficiency is increased, as each device driver may register for the subset of functions it can most efficiently handle, without hooking operating system functions or handling all state specific functions associated with a particular device function. In addition, device driver development may proceed in an incremental fashion, and device driver developers do not have to learn details of every operating system on which a device may be installed.

Title: Non-coatable drywall finishing system
Inventor: SMYTHE TIMOTHY D JR
IPC: E04F13/06
Filed: 1996-10-16
Abstract: A drywall finishing system apparatus and method used to finish seams and corners in modern drywall construction. Interior and exterior flex-trim pieces are made having flanges (1) with an outer surface (2) prepared to directly receive paint or texture. These pieces can be supplied in standard lengths or on rolls. The flanges are scored (7) or grooved (8) to fold to fit into drywall seams. To use the pieces, the drywaller simply applies wet drywall mud to the seam and presses the piece into position. The optionally tapered or beveled edges (3) are then "killed" with a wide blade tool. When the mud dries, the piece is ready to receive paint or texture without sanding. It is possible to kill the edges a second time to achieve a perfect kill.

IPC: G01P9/00
Filed: 1997-07-02
Abstract: A magnetohydrodynamic sensor having an annular sense channel containing a conductive liquid proof mass (11, 12). A radial flow is introduced into the annular channel (14) which, in response to rotation of the device, produces a coriolis force and resulting circumferential velocity of the fluid. An electromagnetic winding produces an alternating electromagnetic field directed perpendicular to the annular channel. First and second electrodes (17, 18) sense a time varying electric potential induced between the center of the annular channel and the circumference of the annular channel.     The time varying electrical potential is proportional to the strength of the time varying electric field and rotational velocity of the channel with respect to said proof mass. The transformer (23) connected to the electrodes provides for amplification of the signal representing the rotational velocity of the channel with respect to the proof mass.

Title: Method and apparatus for measuring pressure in a coriolis mass flowmeter
Inventor: BOSE TAMAL
IPC: G01F1/84
Filed: 1997-08-12
Abstract: A method for determining pressure in an operating Coriolis effect mass flowmeter (10). The Coriolis flowmeter flow tubes (130, 130') are vibrated in both a bending mode (as is normal for measuring mass flow rate) and in a twisting mode. The ratio of the fundamental frequencies at which the flow tubes vibrate in each of the two vibration modes is proportional to the pressure within the flow tubes. In the preferred embodiment, a sum/difference method initially isolates the superposed sinusoids representing the fundamental frequencies of the two vibrational modes. Fast conjugate gradient (FCG) digital filters (512, 514) are then used to rapidly estimate the fundamental frequencies in each of the two vibration modes. The estimated frequencies are then used by filter chains including digital notch (518, 508) and band pass filters (506, 1520) as well as recursive maximum likelihood (RML) digital filter (510, 522) techniques to enhance the bending mode and twisting mode fundamental frequency estimates. The enhanced bending mode andtwisting mode frequency estimates are used to determine the pressure within the flow tubes as a function of the ratio of the two frequencies as well as to center the notch and band pass filter chains used to enhance the bending mode frequency of the two vibration sensor channels for mass flow rate computations. The pressureso determined may then be used to correct mass flow rate computations or for other pressure measurement purposes per se.
