Appl. No.:

10/153546

Inventors:

Steven G. Hand - Westminster CO, US
Arieh Markel - Lafayette CO, US

Kristina A. Tripp - Denver CO, US

Assignee:

Sun Microsystems, Inc. - Santa Clara CA

International Classification:

G06F 12/00

US Classification:

711117, 710 53, 710 52

Abstract:

Provided are a computer implemented method, system, and program for accessing information on a device. A first and second buffers are generated in a computer readable medium. The first buffer is indicated as a read buffer. Property values are returned from the buffer indicated as the read buffer in response to requests for property values for the device. The second buffer is indicated as a refresh buffer. Updates to the property values accessed from the device are written to the buffer indicated as the refresh buffer.

US Classification:

719315, 719321, 710 15

Abstract:

Provided are a computer implemented method, system, and program for enabling access to information from a device. A device program is generated to access device property information from the device. Each device property indicates a state of the device and the device program includes device specific commands to query the device for information on the device properties and device independent statements common to device programs for other devices to buffer the queried property information to return to requesting clients. The device program is stored in a computer readable medium.

International Classification:

C12N 5/00
A01N 1/02

US Classification:

435374, 435 13

Abstract:

A method is disclosed for reliably stabilizing eukaryotic cells that express the P2Xreceptor channel, particularly mammalian and other vertebrate cells, including human cells, for example mammalian macrophages, or hematopoietic stem cells, in order to introduce otherwise membrane-impermeable compounds that are helpful for stabilizing the cells during drying, chilling, freezing, freeze-drying, or cryopreservation. The cells are exposed to extracellular ATP in concentration sufficient to open pores in the plasma membrane. One or more otherwise membrane-impermeable compounds that aid the survivorship of cells are then introduced, for example, trehalose, and after a brief time the pores are closed—for example, by adding divalent cations, or by diluting the extracellular solution. Once the trehalose or other stabilizing compound has been introduced, the cells may be stably preserved. By taking advantage of an endogenous mammalian receptor and ATP, no antigenic compounds need be introduced.

US Classification:

380 25

Abstract:

A method of distributing a plurality of data files to a plurality of recipients including the steps of: placing encrypted copies of the data files to be distributed on a plurality of identical media and providing the recipients with media reading devices having data file decryption capability; logically arranging the data files into data file groups; in response to a recipient's request for access to selected file groups providing the recipient with a group access map indicative of the file groups to which access is requested; in further response to a recipient's request for access to selected file groups providing the recipient with a password to be used for access verification; completing an access verification operation using the group access map and the password and data indicative of the media being read and data indicative of the reading device being used; providing access to the data files in the file groups to which access is requested by use of the group access map; and decrypting the accessed data files.

US Classification:

Abstract:

A method of protecting soluble proteins such that their biological activity is preserved after freezing by exposing the protein to an amino acid or trimethylamine-N-oxide and transition metal ion prior to freezing. The protected protein can then be thawed without denaturation or impairment of the protein's biological activity. The protein is preferably exposed to the amino acid or trimethylamine-N-oxide by placing it in a 25-100 mM aqueous solution of organic solute and 1 mM Zn. sup. +2. This method is especially effective in preserving the biological activity of fragile proteins such as the enzyme phosphofructokinase. The present method can be used to preserve pharmaceutically useful proteins in a frozen form for storage and distribution. The treated protein can be thawed and administered directly to a user without removing the cryoprotectant since the amino acid or oxide and trace amounts of many transition metal ions are nontoxic.
