摘要:
The present invention provides a process for producing low fibrillating cellulose fibers by a dry-jet-wet spinning process wherein cellulose is treated with a solvent containing imidazolium ionic salt in a spinneret maintained at a temperature of 100-120° C. and the spun fibers drawn to the coagulation bath containing ionic salt with the draw ratio less than 5, to produce fibers with fibrillating index less than or equal to 3.

The method herein teaches encrypting a Private Key using a Passkey from an RSA generated private key/public key pair; the encrypted Private Key is split and then the portions are stored in two different databases. To encrypt data a new AES key is created that encrypts the data that is stored in another database. All users have their AES key encrypted using their associated public encryption keys such that the encrypted AES keys are stored in another database. To decrypt data the user enters his PassKey that is used to decrypt a rejoined split private key from portions that were retrieved from their respective databases. Next the encrypted AES key is retrieved and decrypted using the decrypted Private Key. Finally the AES encrypted data is retrieved from a database and decrypted using the decrypted AES key.

An apparatus for a security system is described. The apparatus includes a plurality of security cameras, a monitoring processor that tracks a focus of attention of a user via selection of cameras one at a time from among the plurality of security cameras, a collection processor that detects an evidence collection request from the user, opens an evidence file in response thereto and saves a sequence of video images from at least some of the plurality of video cameras into the evidence file based upon the tracked focus of attention of the user.

Navigating among content data via a navigation interface includes receiving navigational input including category input and/or page input. The category input and page input each can be selected regardless of what page is currently selected. The selected page fills a substantial portion of the display space. A navigation bar including display elements of available categories also can be displayed. Touch support can be implemented using at least two different systems: Tap and Gesture. Gesture navigation can be inverted to suit the style of a particular user.
摘要:
The inventive system and method for enabling interactive collaboration among video surveillance operators is presented. The device has a message including an incident or meta data having a source identifier, a meta data composer, a transport layer, and a display device, such that the message is packaged using the meta data composer and transmitted using the transport layer to the display device. One embodiment facilitates sharing using a common console, and the other facilitates sharing to one or more operators; both embodiments use a common Meta Data messaging mechanism. Meta data refers to any surveillance related data that is worthy of sharing between operators. It includes, but is not necessarily limited to, salvo information, camera, incident related data, video device location details, etc.

摘要:
A flame retardant and glow resistant zinc free cellulose product containing silica, modified with polyaluminium ions. In the preparation of product the cellulose solution (viscose) and sodium silicate are blended and regenerated to obtain a polymeric silica in the cellulose structure which is further modified with polyaluminium ions to attach aluminium sites on silica molecules to make the product glow resistant and impart wash fastness as well.
