Abstract: A tree-based data store comprising a forest of interconnected trees is generated and/or accessed. The tree-based data store comprising a first tree that depends from a first root node and may include a plurality of branches.  Each of the branches of the first tree ends in a leaf node (Fig. 3c 350). Each leaf node may represent an end product, or a subcomponent node. A second root of the same tree-based data store is linked to each leaf node representing an end product (Fig. 3c 356). Finally, the tree-based data store comprises a plurality of trees in which the root node of each of these trees can be described as an elemental node. The root node of each of these trees may be linked to one or more nodes in one or more branches of the first tree (Fig..9a). The nodes of the tree-based data store contain only pointers to other nodes in the tree-based data store, and may contain additional fields wherein one such may be a count field. Additionally, means to get probabilities of the coincidence of variables related to particular nodes as identified by desired contexts within one or more defined foci are described.  Further, the application of logical operators to queries regarding such variables is shown.

Abstract: A broadband wireless access communication system having a sleep mode in which there is no data to be transmitted or received to/from a base station by a subscriber station, and an awake mode in which there is data to be transmitted or received to/from the base station by the subscriber station. The subscriber station sets a next sleep mode after a sleep interval between a start time of the sleep mode and a start time of the awake mode has reached a given maximum window value. The subscriber station receives a traffic indication message indicating absence of data to be transmitted from the base station after the start time of the awake mode; transmits a sleep request message to the base station; receives a response message to the sleep request message from the base station; and then operates in the next sleep mode.

Filed: 2004-10-15
Abstract: The invention relates to an authorization verification method and devices suited therefor, which play back authorization data via a user interface (11) of an electronic playback device (1). During the playback of authorization data via the user interface (11) of a first playback device (1), the playback attributes are modified. The playback of authorization data via the user interface (11) of the first playback device (1) is compared with the playback of reference data via a user interface (21) of a second electronic playback device (2). Authorization is granted in the event the playback of authorization data via the user interface (11) of the first playback device (1) matches the playback of reference data via the user interface (21) of the second playback device (2), and modifications of the playback attributes are, in essence, time-synchronized. The dynamic modification of the playback attributes during the playback of authorization data and playback of the reference data render practically impossible the unauthorized copying of image contents or audio contents for falsifying an authorization. In addition, a simultaneous playback of authorization data and reference data render unnecessary inquiries made to an authorization center (3).

Inventor: BENSON GLENN STUART
IPC: G06Q20/00
Filed: 2004-10-26
Abstract: A technique for providing message authenticity includes accepting transaction information, accepting a first data item used for authenticating an originating user, cryptographically processing the transaction information using only a second data item, wherein the entropy of the first data item is less than the entropy of the second data item, and authenticating the originating user using the first data item. The first data item can be a sequence of digits corresponding to those displayed on an external device, such as, for example, an RSA authorization token, credit card, etc. In general, the first data item will be a short alphanumeric string and the second data item will generally be much larger, e.g., a 128 bit sequence to be used principally for data authentication. According to another aspect of the present invention, consequential evidence of the transaction may be secured to provide after-the-fact evidence of the transaction. This evidence can include a message written to a tamper-resistant log record, the message including the transaction information, the first data item, the second item, and an identifier for the originating user, as well as other information. At a subsequent point, the transaction can be shown to have been sent by the originating user and received by the intended recipient, by consulting the log record. Preferably, the validity of the transaction would be ascertained by an independent, mutually trusted third party.

Abstract: A composite stent structure includes separate and distinct stent elements or members: an outer stent element and an inner stent element removably attached to the outer stent element. The outer element may be, for example, a bioabsorbable stent typically constructed of a relatively non-resilient material such that the outer bioabsorbable stent element may not be self-expanding and subject to migration within the lumen over time. In contrast, the inner element may be, for example, a removable SEMS used to urge and maintain the outer element in position in the body lumen. The temporary inner SEMS may retain the composite structure (including the underlying inner element) in position until such time as the outer element is appropriately incorporated into the surrounding tissue or some other criteria occurs such that the removal of the SEMS is indicated. The SEMS may then be detached from the outer element and removed from the body lumen.

Title: Network architecture for data transmission
Inventor: KALNITSKY YURY
IPC: H04N21/6437
Filed: 2005-01-14
Abstract: A content distribution network with client side multicasting properties that operates with a reduced bandwidth is provided. The requested content, such as multimedia content, is provided in a format suitable for transmission over existing unicast communication links and is then changed to a multicast format for local distribution. This allows an application provider to transmit a single unicast stream of content to a client-side media server in a local area network (LAN) and then distribute it to multiple interested users within the LAN using a multicasting transmission format. This significantly reduces bandwidth requirements by providing a single unicast transmission to a LAN  rather than supply each user within the LAN with a dedicated content stream.
