Title: Method and apparatus for auditing dynamically linked procedure calls
Inventor: WALKER MICHAEL S
IPC: G06F9/445
Filed: 1998-01-28
Abstract: The present invention is a method and apparatus for providing instrumentation of procedure calls in dynamically linked environments. More specifically, an embodiment of the present invention includes an API that allows a user to define procedures that are called during specific times during the execution of a runtime linker. By defining procedures in accordance with this API, the user can select procedures within a user program for auditing. The API also allows the user to define an entry procedure that will be called immediately before each audited procedure and an exit procedure that will be called immediately after each audited procedure. The runtime linker uses the procedures defined by the user to select procedures within the program for auditing. The runtime linker then arranges for the entry procedure to be called before, and the exit procedure to be called after, each audited procedure.

Title: Local and zone time data conversion processing for date-dependent information which spans one or two centuries
Inventor: ALTER HARVEY
IPC: G06F17/30
Filed: 1996-10-31
Abstract: Date-dependent information in two digit format where the dates may occur in one or two centuries is provided for by time change interfaces (108) that convert date data in an external data file (114) from local time to zone time in zone input files (104) so that all dates occur in one century. Application programs (106) process the zone input files (104) using zone time instead of local time. After processing the zone time in the zone output files (113, 111) is processed by time change interfaces (110, 109) to yield output data in local time (112, 115). By this inventive method, necessary two digit date format programming changes to the application programs (106) due to the turn-of the century problem are minimized or eliminated.

Title: Improved methods for the production of non-covalently complexed and multivalent proteosome sub-unit vaccines
Inventor: LOWELL GEORGE H
IPC: A61P31/04
Filed: 1996-09-18
Abstract: A method for preparing multivalent proteosome-amphiphilic determinant vaccines suitable for parenteral or mucosal administration using diafiltration or ultrafiltration technology. The amphiphilic determinants include lipopolysaccharides from gram negative bacteria, e.g. S. flexneri, P.  shigelloides and S. sonnei. Proteosomes are obtained from group B type 2b meningococci. The active proteosome-amphiphilic determinant complexes (non-covalently complexes) of the vaccine are formed using diafiltration or ultrafiltration to remove the detergent. The use of diafiltration or ultrafiltration decreases processing time and the opportunity for contamination and further permits the use of ambient temperature and efficient scale-up. In addition, the process permits the reliable and continuous monitoring of the dialysate which enhances the efficiency of the entire process. The time of dialysis for production of a lot of vaccine is reduced from > 7-10 days to less than 72 hours and usually less than 48 or 24 hours.  The use of the process optimizes the presence of each antigenic component in the preparation of multivalent vaccines.

Title: The wristthotic chariot
Inventor: CORBETT DONALD L
IPC: G06F3/039
Filed: 1998-07-17
Abstract: The Wristthotic Chariot (also referred to as the invention) is a device designed to relieve the discomfort of Carpal Tunnel Syndrome and wrist/arm Repetitive Strain Injury (RSI) often caused by the utilization of the computer tracking device commonly referred to as the "mouse". When the mouse is use, it may, from time to time, cause the wrist to bend, stretch, receive pressure and experience repetitive motion. The invention enables the wrist to maintain a more neutral position to avoid such pronation, wrist extension and ulnar nerve deviation that may cause nerve irritation, tendon and muscle strain that often leads to RSI, the most common known as Carpal Tunnel Syndrome (CTS). The carpal tunnel is a small space in the wrist containing tendons, nerves and blood vessels which can become tingly and sore when stressed by repetitive finger use and extended (bent back) wrist posture. The invention is attached to an existing mouse's upper surface in the fashion similar to that of a chariot or buggy attached to a vehicle. The invention may be attached in two fashions: 1. Accessory: Via the use of a dome, suction cup or Velcro tm., so as to allow for the removal and adjustment of the invention as required or preferred by the user. 2. Mouse Extension: The invention can be fixed permanently to the mouse to create an elongated mouse that extends to the wrist area. The invention raises or elevates the wrist while the wrist is resting upon the invention's foam/plastic support which is elevated to a height of one half to 3 inches (1.5 to 8 centimeters). while laying on a flat surface or mouse pad While in this state of elevation the wrist is both supported and/or cushioned by the invention. Due to its attached nature, the invention moves with the mouse unlike prior art/conventional wrist rests/wrist bars that remain static. Such attachment of the invention to the mouse ensures the wrist remains in a more constant fixed position as the mouse is guided and maneuvered by the user.

Title: Method and apparatus for cough sound analysis
Inventor: AFSHARI ALIAKBAR
IPC: A61B7/00
Filed: 1999-04-23
Abstract: A fast, simple, and reliable method and apparatus for recording cough sounds for diagnosing pulmonary disorders and diseases is provided. This method uses signal analysis techniques to extract quantitative information from recorded cough sound pressure waves. The generated data can be used to diagnose pulmonary disorders and diseases as well as track the effectiveness of treatment regimens over time.  The method can also be used to quickly and reliably screen individuals at risk of pulmonary disorders and diseases. The discovery of early stages of pulmonary disorders or diseases may allow earlier treatment and/or environmental modification to reduce the risk or irreversible injury to pulmonary function. The system, which is a simple, non-invasive system that can quickly and easily be administered with minimum technician and patient training, uses a mouthpiece, a tube having a distal end and a proximal end, a flexible tubing having a distal end and a proximal end, and a microphone;  wherein the mouthpiece is attached to the proximal end of the tube, wherein the distal end of the tube is attached to the proximal end of the flexible tube, wherein the microphone is attached to the tube between its distal and proximal ends such that the microphone can record sound pressure waves within the system without distorting the pressure waves, and wherein the flexible tubing is sufficiently long so there are essentially no reflected sound pressure waves which interfere with the recording of the sound pressure waves at the microphone. Preferably, the system also includes a computer system to assist in recording and analyzing the sound pressure waves. A calculated cough sound index (CSI) can be used in diagnostic applications.
