Title: In-building modulated backscatter system
Inventor: SHOBER R ANTHONY
IPC: H04B1/59
Filed: 1997-10-27
Abstract: In accordance with the present invention, a radio communications system is disclosed that can operate in one of several Modes which integrate in-building security, location determination, messaging, and data communicationscapabilities. The radio communication system includes at least one Interrogator for generating and transmitting a radio signal. One or more Tags of the system receive the radio signal. A Backscatter Modulator modulates the reflection of the radio signal using a subcarrier signal, thereby forming a reflected modulated signal. The Interrogator receives and demodulates the reflected modulated signal. The Interrogator can also transmit a first information signal to one or more tags, specifying which tags should respond using Backscatter Modulator means. In the Interrogation Mode, the Interrogator can determine the identity of the Tags in the reading field, and can exchange data with those Tags that have been identified. In the Location Mode, the radio communications system can instruct some or all Interrogators to determine the location of a Tag or Tags within the building, regardless of whether the Tag or Tags are in radio range of the Interrogation Mode. In the Messaging, or low speed data communications Mode, the radio . communications system can instruct some or all Interrogators to transmit a command addressed to a particular Tag or Tags, regardless of whether the Tag or Tags are in the reading field of the Interrogation Mode, requesting that Tag or Tags performsome action. Other embodiments of the Messaging Mode allow the Interrogator to transmit data in addition to a command to the Tag or Tags, and also for the Tag or Tags to transmit a signal back to the Interrogator. This radio communications system can be interconnected with other communications capabilities such as electronic mail, voice mail, location, inventory management, and other systems.

Patent CA-2224030-A1 (CA)
Title: Fence wire stretcher
Inventor: HAY PATRICK JAMES
IPC: B21F9/00
Filed: 1997-12-08
Abstract: A wire clamp device affixed to an outer end of a bar in a wire tightener of the type having a stationary wire holding clamp at an opposite end of the bar. A carrier is mounted on the bar and is also provided with a wire holding clamp. The bar is provided with a jack rack and the carrier has a jack mechanism for forcibly driving the carrier toward the first wire holding clamp so as to pull end portions of two strands of wire held by the two wire holding clamps toward each other. The wire clamp device which also has a wire holding clamp is positioned to hold the strand held by the wire holding clamp of the carrier after it has been drawn towards the first wire holding clamp so that the wire holding clamp on the carrier may be released to allow the carrier to be reset to a position near the wire clamp device, after which the wire holding clamp on the carrier is again activated to grasp again the tightened strand which it had previously held. The carrier can again be driven toward the stationary wire holding clamp at the opposite end after release of the strand from the wire clamp device. The presence of the wire clamp device makes it unnecessary to temporarily fasten the strand being tightened by movement of the carrier in order to allow the carrier to be reset to a position for further tightening of the strand.

Title: Synchronizing the transmission of data via a two-way link
Inventor: PETERSEN LARS GOERAN
IPC: H04L49/111
Filed: 1996-06-13
Abstract: Transmission in a cell based switch of user cells which can include different numbers of data bits is synchronized. The transmission is performed via a twoway link between functional entities which each includes a link control function containing functions for starting and controlling transmission of data on the link by means of sync cells which are exchanged between the link control functions. The exchange of sync cells is controlled by a sync state machine having three states (304, 308, 312). In a HUNT state (312) the link control function investigates a sync cell coming in from the link for establishing whether it agrees with a predetermined pattern for sync cells. In a PRESYNC state (304), that starts after a sync cell containing the predetermined pattern has been found in the HUNT state, the link control function investigates a predetermined number thereafter incoming consecutive sync cells for establishing whether they contain the predetermined pattern. If this is not the case the control process returns to the HUNT state. In a SYNC state (308), that starts after the predetermined number of sync cells containing the predetermined pattern has been found in the PRESYNC state, transmission of data on the link is admitted while supervising data with respect to faults. If faults are found the control process starts again in the HUNT state.

Patent CA-2227291-A1 (CA)
Title: Electrophysiological activity estimation method
Inventor: KIYUNA TOMOHARU
IPC: G16H10/60
Filed: 1998-01-16
Abstract: An electrophysiological activity estimation method is used to estimate active areas of a selected part of a living body (e.g., human brain). Based on electromagnetic field distribution measured on a surface of the selected part of the living body as well as its shape, the method assumes each equivalent current dipole as a source of electromagnetic field distribution. At first, grid points are created to cover the selected part of the living body (e.g., head). Using the pseudoinverse, the method performs estimation of dipole distribution for equivalent current dipoles. Then, the equivalent current dipoles are subjected to sorting based on a priority order. An evaluation function (e.g., structural risk) is calculated in accordance with a square error between the measured electromagnetic field distribution and a theoretical value of electromagnetic field distribution caused by the equivalent current dipole, as well as a number of measuring points and a number of equivalent current dipoles. Estimation and calculations are repeated while changing a number of equivalent current dipoles in accordance with the priority order. Then, noise distribution is estimated in response to a minimum value of the evaluation function. So, the dipole distribution is estimated using the noise distribution. Thus, it is possible to obtain estimation results which are represented by a direction and magnitude of the equivalent current dipole as well as an appropriate number of equivalent current dipoles.

Title: Method and apparatus for constructing three-dimensional bodies from laminations
Inventor: CAWLEY JAMES D
IPC: B32B38/18
Filed: 1996-08-02
Abstract: A method for manufacturing an integral three-dimensional object (60) from laminations (48) includes the steps of fabricating a plurality of first sheets (44) of a first material composition, cuttting each of the first sheets to form a contoured layer (48) representing a cross section of the three-dimensional object and to form a waste material and discarding the waste material. The contoured layers are stacked in a desired sequence to form a stack (50) of contoured layers which are then laminated. Subsequently, the contoured layers of the stack are secured to each other to form the intergral three-dimensional object (60). This method works particularly well with ceramic material sheets (72). If desired, a second type of sheet (76) made of a fugitive material can also be cut to form a contoured layer representing a void in a cross section of the three-dimensional object. The contoured layers of the second sheets are then stacked along with the contoured layers of the first sheets to form the object. The laminated stack of contoured layers is then sintered. During processing, fugitive material can be removed, leaving voids in the three-dimensional object.
