Patent CA-2485423-C (CA)
Inventor: POTAPOV DMITRY M
IPC: G06F7/00
Filed: 2003-05-12
Granted: 2013-10-08
Abstract: A method and mechanism is disclosed for implementing storage and retrieval of data in a computing system. Data compression is performed on stored data by reducing or eliminating duplicated values in a database block. Rather than writing the duplicated data values to the data storage unit, the on-disk data is configured to reference a copy of each duplicated data value stored in a symbol table. A method and mechanism of improving performance of database query language statements is also disclosed. Information describing data duplication within a data block is maintained. In one embodiment, the data duplication information is used to reduce number of predicate evaluations on data in the data block when a database query language statement is received against the data in the data block. In another embodiment, the data duplication information is used to reduce amount of data accessed by a database query language statement.

Filed: 2005-01-05
Granted: 2008-03-18
Abstract: A multi-position sleeping structure includes a sheet material envelope defining a cavity with an opening. An inflatable mattress is received and substantially enclosed within the cavity of the sheet material envelope. A cover portion which, in conjunction with a top surface of the envelope, defines a sleeping area in which a person can lie and be supported by the mattress. The mattress has a plurality of transversely extending hinges that separate the mattress into a first portion, a second portion, and a third portion. The hinges allow the mattress to be moved between at least a substantially horizontal sleeping position and a seating position. The sheet material envelope has a retaining pouch to retain the mattress in the seating position. The retaining pouch is suitably sized and positioned to receive the mattress and sheet material envelope therein for storage purposes when the mattress is in the deflated storage condition.

Title: Efficient management of cryptographic key generations
Inventor: SELANDER GOERAN
IPC: H04L9/08
Filed: 2004-10-13
Granted: 2013-09-24
Abstract: The invention generally relates to management of cryptographic key generations in an information environment comprising a key-producing side generating and distributing key information to a key-consuming side. A basic concept of the invention is to define, by means of a predetermined one-way key derivation function, a relationship between generations of keys such that earlier generations of keys efficiently may be derived from later ones but not the other way around. A basic idea according to the invention is therefore to replace, at key update, key information of an older key generation by the key information of the new key generation on the key-consuming side. Whenever necessary, the key-consuming side iteratively applies the predetermined one-way key derivation function to derive key information of at least one older key generation from the key information of the new key generation. In this way, storage requirements on the key-consuming side can be significantly reduced.
