Publication number: 20070150737Abstract: Techniques for registering certificates after the issuance of the certificates are provided. A service provider securely registers a client's identity and its certificate without depending on or using an existing basis of trust, such as that provided by domain-joined clients or a security directory (e.g., MICROSOFT's ACTIVE DIRECTORY). The service provider provides services, such as, by way of example and not a limitation, email services, web application services, application services, etc., based on identifiers (e.g., service IDs) issued to registered clients. The service provider subsequently uses the issued identifier to authenticate a client requesting a service or services, and to authorize the client to receive the requested service or services.Type: ApplicationFiled: December 22, 2005Publication date: June 28, 2007Applicant: Microsoft CorporationInventors: Gopal Parupudi, Prabhu Padhi, Rajagopalan Narayanan, Ram Sunkara, Sean Cannella, Tak Lung, John Ellis

Publication number: 20060011727Abstract: A micro bar code and a recognition system and method thereof are provided. The micro bar code has a plurality of nanomolecules disposed thereon in a predetermined arrangement. In the recognition system and method, a sensing module senses the arrangement of the nanomolecules on the micro bar code. The sensing result from the sensing module is transmitted to an operating module and then inputted to a bar code database that stores information corresponding to arrangement of each set of nanomolecules, so as to recognize information on the micro bar code to be recognized. Finally, the recognition result is transmitted back to the operating module for recording. The micro bar code has advantages of small size and large data storage capacity.Type: ApplicationFiled: July 14, 2004Publication date: January 19, 2006Applicant: CULTURE.COM TECHNOLOGY (MACAU) LTD.Inventors: Kung-Cheng Lin, Tak-Lung Yiu

Publication number: 20050171982Abstract: An integrated circuit (IC) module allows volatile data generated by applications to be stored within volatile data files in the volatile memory. A file system tracks the location of all data files as residing in either volatile memory or nonvolatile memory and facilitates access to the volatile data files in volatile memory in a similar manner to accessing nonvolatile data files in nonvolatile memory. The file system exposes a set of application program interfaces (APIs) to allow applications to access the data files. The same APIs are used to access both volatile data files and nonvolatile data files. When an application requests access to a data file, the file system initially determines whether the application is authorized to gain access to the data file. If it is, the file system next determines whether the data file resides in volatile memory or nonvolatile memory. Once the memory region is identified, the file system identifies the physical location of the data file.Type: ApplicationFiled: March 31, 2005Publication date: August 4, 2005Applicant: Microsoft CorporationInventors: Vinay Deo, Mihai Costea, Mahesh Lotlikar, Tak Lung, David Milstein, Gilad Odinak

Patent number: 5952422Abstract: Method for forming a polyurethane based adhesive composition in which a reaction mixture of at least one NCO-terminated prepolymer and a polyhydroxy compound is heated at a temperature and for a length of time sufficient to provide a gel content of from about 30 to 42% by weight and a molecular weight of extractables of at least about 45,000. Polyurethane based adhesives prepared by the method and medical devices employing the same are also disclosed.Type: GrantFiled: December 18, 1996Date of Patent: September 14, 1999Assignee: Bristol-Myers Squibb CompanyInventors: Tak-lung Chang, Sheng-hung Kuo, Kishore Shah, Agis Kydonieus

Patent number: 5714543Abstract: In accordance with the present invention novel polyurethane PSAs containing water soluble polymer additives have enhanced water uptake. The water soluble polymer additives suitable for use herein have a solubility parameter in poorly hydrogen-binding solvents (e.g., hexane, cyclohexane and the like) in the range of from 8-10. The water soluble polymers must also be free from moieties which will react with isocyanates. Such PSAs retain their transparency and peel strength characteristics and can still be employed as relatively thin films (i.e., 2 to 100 mils) while exhibiting only minimal swelling when in contact with moist environments.Type: GrantFiled: January 13, 1994Date of Patent: February 3, 1998Assignee: Bristol-Myers Squibb CompanyInventors: Kishore R. Shah, Tak-Lung Chang, Agis Kydonieus

Patent number: 5591820Abstract: Pressure-sensitive adhesives which possess absorptivity and/or permeability properties to remove transepidermal water loss and/or other bodily fluids that come into contact with the adhesive, in combination with a fine balance of cohesion and adhesion properties, can be formulated by controlling the crosslinking of a polyurethane polymer having excess hydroxyl functionality, a glass transition temperature of less than about 0.degree. C., a moisture absorption of at least about 20% of its weight and/or a moisture vapor transmission rate of at least about 300 grams/meter.sup.2 /24 hours measured at 37.degree. C. and a 90% relative humidity gradient. Adhesives of these polymers possess a peel adhesion to human skin of between about 0.3 and 4 newtons/cm width of the polymer or adhesive.Type: GrantFiled: May 9, 1995Date of Patent: January 7, 1997Assignee: E.
