Title: Secure messaging system overlay for a selective call signaling system
Inventor: LAVELL JEFF
IPC: G06Q20/38
Filed: 1998-12-04
Abstract: A secure messaging system (900) generates a secure financial transaction message. A wireless selective call signaling system controller (102) receives the secure financial transaction message as a selective call message request including a destination identifier. A selective call message processor (1104) encapsulates the secure financial transaction message in a selective call message that includes a selective call address corresponding with the destination identifier. A selective call transmission service (904) conveys the selective call message to a financial messaging unit (906) that receives the selective call message, and in response to correlating the selective call address with a selective call address corresponding with the financial messaging unit (906), recovers the secure financial transaction message to effect a financial transaction.

Title: Optical switch and protocols for use therewith
Inventor: WANG GUO-QIANG
IPC: H04B10/291
Filed: 2000-07-21
Abstract: A method of establishing a data connection between terminal switching nodes in a network and switching nodes for implementing the method. The method involves switching nodes participating in a network layer wavelength routing (WR) protocol to determine the next hop switching node for every possible combination of terminal nodes based on the network topology. The method also involves the switching nodes participating in a network layer wavelength distribution (WD) once the data connection is to be established. The WR protocol determines the path used through the network, while the WD protocol assigns wavelengths on each link between switching nodes. The wavelengths may be different on different optical links. The switching nodes include wavelength converters with an optical switch or optoelectronic converters with a digital electronic switch. A digital electronic switch can also provide signal reformatting. Advantages of using potentially different wavelengths along various segments of a single end-to-end connection yields increased wavelength efficiency.

Inventor: LESZMANN RALPH
IPC: G06K9/20
Filed: 1999-11-05
Abstract: The invention relates to a method for electronically recording an image of the surface of an object which can be represented as a function G(x, y), wherein x and y represent the coordinates of a respective spot image of the image (50, 51, 52, 53, 54, 55) and G represents its halftone value. According to said method, the object is recorded sequentially over various times ti, with ti+ 1>ti being recorded from various perspectives as a function Gi so as to produce the entire image G like when a finger (8) is rolled off for recording a fingerprint from the individual images Gi(x, y). Partial zones are cut out from the individual images and are joined depending on the perspective from which they have been recorded. A curved intersection line (76) is determined to determine the partial zones of every image except the first image Gi by comparing the image content of the previously recorded or joined image Gi-1. Said intersection line delimits the partial zone of the image (50, 51, 52, 53, 54, 55) Gi-1 and the corresponding partial zone of image Gi is joined at this intersection line (76) to produce the entire image G(x, y). Said intersection line (76) is determined by establishing a similitude function Gc(x, y) between the images Gi and Gi-1. Said function becomes extremal at identical halftone values at identical image spot coordinates or also including their surroundings. Said intersection line (76) is represented by the course of a curve y(x) which intersects at least one extreme of highest similitude of the similitude function Gc(x, y).

Inventor: ALLEN ROSANNE J
IPC: H04M3/523
Filed: 2000-10-18
Abstract: In a network of call centers, each call center sends real-time call center management information to a network call center controller at a regular interval. An administrator can configure a routing preference for each network skillset. At a regular interval, the received real-time call center management information is evaluated by the network call center controller, based on the administrator configured routing preferences, and updated routing tables are automatically determined for each network skillset. The updated routing tables are then sent by the network call center controller to each call center. Each call center then uses the updated routing tables to queue inbound calls to multiple remote call center servers as well as locally.

Title: Oxidase process for pulp and dye oxidation
Inventor: LEECH DONAL
IPC: D21C9/10
Filed: 1999-04-13
Abstract: This invention describes a novel method for selectively delignifying lignocellulosic materials and bleaching of pulp and dyes using a combination of an oxidative enzyme and a metal complex. More specifically, the process involves the oxidation of a transition metal redox complex by a phenol oxidizing enzyme such as laccase or peroxidase to mediate the catalytic delignification of chemical pulp and bleaching of textile dye. This process is unique in that only a catalytic amount of metal complex mediator is required on softwood or hardwood kraft pulp, and that recycling or regeneration of the mediator for further pulp delignification is possible. The redox mediator is characterized in that it contains a transition metal ion coordinated with molecules or ions in such a way that the complexes have a formal redox potential between 0.5 and 1.2 volt measured against a normal hydrogen electrode.

Abstract: Signal construction, detection and estimation techniques for use in uplink timing synchronization and access control in an orthogonal frequency division multiplexed (OFDM) wireless system or other type of wireless communication system. In accordance with an illustrative embodiment of the invention, timing and access signals to be transmitted in designated timing and access intervals are constructed from orthogonal multitone signals. The multitone signals may be similar to multitone signals used in OFDM data transmission, except that a cyclic prefix associated with reception of the signals in a base station is extended to cover the timing errors of mobile stations not yet synchronized. The invention also provides design techniques which optimize the time resolvability and peak- to-average ratio of the multitone signals, an efficient fast Fourier transform (FFT) based technique for maximum likelihood timing estimation, and a robust linear filtering technique for averaging timing estimates from different synchronizations.

Title: Door or gate closure
Inventor: SCHUTTE WOLFGANG
IPC: E06B9/06
Filed: 1998-07-30
Abstract: The invention concerns a door or gate closure, comprising substantially rectangular closure elements (2) superposed horizontally and parallel, moving relative to one other by overlap. The closure elements (2) are driven such that the second closure element (2) moves at a speed double that of the first, and the third element moves three times faster than the first, and the last element moves at a speed corresponding to the speed of the first element (2) multiplied by the number of closure elements (2). Thus, when the gate is opened or closed, only the closure element (2) located the lowest moves over the whole height with maximum speed, whereas the remaining closure elements (2) must move at a proportionally slower speed over proportionally shorter distances, thereby globally resulting in a favourable energy balance for opening or closing with such a gate closure system.
