Title: Interface for representing effects in a multilanguage optimizing compiler
Inventor: DAVIDSON CAROLINE SWEENEY
IPC: G06F9/45
Filed: 1992-02-18
Abstract: A compiler framework uses a generic "shell" or control and sequencing mechanism, and a generic back end (where the code generator is target-specific). The generic back end includes the functions of optimization, register and memory allocation, and code generation. The shell may be executed on various host computers, and the code generation function of the back end may be targeted for any of a number of computer architectures. A front end is tailored for each different source language, such as Cobol, Fortran, Pascal, C, C + +, Ada, etc. The front end scans and parses the source code molecules, and generates from them an intermediate language ("IL") representation of the programs expressed in the source code. This IL is constructed to represent any of the source code languages in a universal manner, so the interface between the front end and back end is of a standard format. and need not be rewritten for each language-specific front end. The IL representation generated by the front end is based upon a tuple as the elemental unit, where each tuple represents a single operation to be performed, such as a load, a store, an add, a label, a branch, etc. A data structure is created by the front end for each tuple, with fields for various necessary information. One feature of the invention is a mechanism for representing effects and dependencies in the interface between front end and back end; a tuple has an effect if it writes to memory, and has a dependency if it reads from a location which some other node may write to. A mechanism independent of source language is provided for describing the effects of program execution. Another feature is the use in the optimization part of the compiler of a method for analyzing induction variables, where the improvement is to use the side effects sets used to construct IDEF sets. Another feature is a mechanism for "folding constants" (referred to as K-folding or a KFOLD routine), included as one of the optimizations. A further feature is the type definition mechanism, referred to as the TD module, which provides mechanisms used by the front end and the compiler of the back end in constructing program type information to be incorporated in an object module for use by a linker or debugger. Another feature is a method for doing code generation using code templates in a multipass manner.

Title: Hemicellulase supplement to improve the energy efficiency of hemicellulose-containing food and animal feed
Inventor: FODGE DOUGLAS WALTER
IPC: A23K1/165
Filed: 1991-05-29
Abstract: Soil microorganisms are obtained that produce a hemicellulase which is particularly useful in increasing the available energy content of hemicellulosic foodstuffs.      These microorganisms can be cultured per se or can be used as sources of genetic information with which to engineer other microorganisms to produce the enzyme. Thus, commercially useful quantities of native or recombinant hemicellulase can be produced with cultures consisting essentially of microorganisms that produce the enzyme. The hemicellulase, a culture consisting essentially of a microorganism that produces such a hemicellulase, or a fermentation broth comprised of such a culture and hemicellulase can then be employed in a consumable composition containing complex carbohydrates which the enzyme degrades, enhancing the nutritional value of the composition.

Title: Glutathione-s-transferase mu as a measure of drug resistance
Inventor: PERO RONALD W
IPC: C12Q1/68
Filed: 1992-12-08
Abstract: GLUTATHIONE-S-TRANSFERASE MU AS A MEASURE OF DRUG RESISTANCE           ABSTRACT OF THE INVENTION      It has been discovered that by determining or measuring a person's glutathione-s-transferase (GST) mu activity one can determine or measure the individual's resistance to drugs, particularly to chemotherapeutic drugs.  Approximate-ly 50% of the human population exhibit substantially no GST mu activity, with the remaining 50% showing GST mu activity. This remaining 50%  of the population accordingly,  when treated with drugs,  such as a chemotherapeutic drug for cancer therapy, show less effective response to the drug therapy than the other 50% of the population which have substantially no GST mu activity,  since GST mu tends to deactivate drugs.   Accordingly,  a person having GST mu activity would exhibit drug resistance and would not benefit as  much  by  or  be  as  good  a  candidate  for  cancer chemotherapy as a person who has no GST mu activity.

Filed: 1993-09-24
Abstract: SYST?ME PERSONNEL DE PROTECTION POUR L'AUTOMOBILISTE Les systèmes habituels d'alarme pour voitures ne protègent que celles-ci. Par contre, notre système protège aussi l'usager qui peut, à l'aide d'une télécommande à longue portée, déclencher volontairement à distance la sirène située dans sa voiture, de manière à décourager une tentative d'agression à son endroit. De plus, si l'usager se fait voler sa voiture à la pointe d'une arme ("carjacking"), il peut aussi utiliser la télécommande pour couper le moteur de sa voiture, une fois le voleur éloigné de lui à une distance sécuritaire, et ainsi neutraliser la tentative de vol. De plus, si la voiture possède un système électromécanique pour barrer les portes, ce système peut être activé en même temps que la coupure des moteurs, emprisonnant ainsi le voleur l'intérieur de la voiture jusqu'à la venue des policiers. Pour se faire, la télécommande possède deux boutons principaux: le premier pour contrôler la sirène et le clignotement des feux d'urgence, et le deuxième pour contrôler la coupure du moteur et le verrouillage des portes. Une pression sur un bouton active les fonctions correspondantes, la pression suivante les désactive, et ainsi de suite.
