Appl. No.:

11/191595

Inventors:

Stuart Schaefer - Marblehead MA, US
John Sheehan - Somerville MA, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 13/00
G06F 17/00

US Classification:

719313, 707694, 707695

Abstract:

A method for controlling the interoperation of a plurality of software applications and resources includes intercepting communications from a first application to a second application or resource, directing the communication to a context management system, generating a candidate list of contexts for the communication, evaluating the candidate list according to at least one policy defined for these contexts to identify the resultant action and namespace for the communication, and performing the action as defined by the policies within the identified namespace. The method further includes tracking one or more versions of the second application, as well as tracking an evolution of application and/or resource names. The method further includes identifying one or more operations associated with a context on the candidate list, and executing the identified operations prior to a further communication.

Abstract:

A virtualization system is described herein that facilitates communication between a virtualized application and a host operating system to allow the application to correctly access resources referenced by the application. When the operating system creates a virtualized application process, the virtualization system annotates a data structure associated with the process with an identifier that identifies the virtualized application environment associated with the process. When operating system components make requests on behalf of the originating virtual process, a virtualization driver checks the data structure associated with the process to determine that the helper process is doing work on behalf of the virtualized application process. Upon discovering that the thread is doing virtual process work, the virtualization driver directs the helper process's thread to the virtual application's resources, allowing the helper process to accomplish the requested work with the correct data.

International Classification:

G06F 9/44
G06F 9/445

US Classification:

717168, 717174

Abstract:

A set of high value state in application state for a software application can be distinguished from a set of low value state in the application state. For example, a set of heuristics can be run on the application state to distinguish between the set of high value state and the set of low value state. A set of designations that designate the set of high value state in the application state as high value and that designate the set of low value state in the application state as low value can be generated. When processing the application, the high value state can be processed differently than the low value state. The application may be packaged as a virtual application.

Filed:

Feb 3, 1981

Appl. No.:

6/231260

Inventors:

John C. Sheehan - Lexington MA

Assignee:

Massachusetts Institute of Technology - Cambridge MA

International Classification:

C07D50157
A61K 31545

US Classification:

424246

Abstract:

Biologically active sulfur analogs of 6-aminopenicillanic acid having a nucleophile substituted in the 6- position are made by reacting a sulfenyl chloride with esters of diazopenicillanic acid. Biologically active sulfur analogs of 7-aminocephalosporanic acid having a nucleophile substituted in the 7- position are analogously made by reacting a sulfenyl chloride with esters of 7-diazocephalosporanic acid. Deacetoxycephalosporins can be formed from the corresponding analog of 6-aminopenicillanic acid and derivations thereof, by sulfoxide rearrangement of the thiazolidine ring of penicillins to the dihydrothiazine ring of cephalosporins. These nucleophile substituted sulfur analogs of penicillins and cephalosporins are new antibacterial agents and display antibacterial activity against a variety of microorganisms.

International Classification:

C07D49900
A61K 31425

US Classification:

2602452R

Abstract:

In accordance with this invention, it has been found that carbon and oxygen analogs of 6. beta. -aminopenicillanic acid and biologically active derivatives thereof can be formed from esters of 6-oxopenicillanic acid. For example, 6. beta. -phenoxyacetoxypenicillanic acid--an oxygen analog of penicillin V and 6. beta. -phenoxyacetylmethylpenicillanic acid--a carbon analog of penicillin V, may be formed from an ester of 6-oxopenicillanate. The ester of 6-oxopenicillanic acid is formed by a diiospropyl carbodiimide/dimethyl sulfoxide oxidation of the corresponding ester of 6. alpha. -hydroxypenicillanic acid. The oxygen analogs are formed by reducing the ester of 6-oxopenicillanic acid to the corresponding 6. beta. -hydroxypenicillanate and then forming the desired analog by acylation. The carbon analogs are formed by a Wittig reaction of the ester of 6-oxopenicillanic acid with a suitable acylmethylenetriphenylphosphorane followed by saturation of the newly formed double bond and removal of the protective ester group.
