Patent CA-2279050-A1 (CA)
Title: Brake
Inventor: AMMON URS
IPC: G01L5/28
Filed: 1999-07-28
Abstract: This torque-measuring device for a brake is based on the principle of measurement of the elastic deformation of active parts of a brake. The principle according to the invention is illustrated and explained with the example of a shoe brake. In that case, regions (23, 24) with a reduced bending moment resistance are formed at the brake levers (2, 3) and elastically deform under the action of torque. The elastic deformation is detected by means of strain gauge strips (R1 to R4) arranged in these regions (23, 24) and connected as a measuring bridge and the obtained voltage signals are conducted on to the lift control for the purpose of processing into reference signals (28). By these reference signals a motor torque compensating for the measured torque is generated in the drive motor by way of the drive control before the release of the brake and the thus resulting torque at the brake shaft is brought to zero. A jerk-free setting off, without a torque jump, results therefrom after release of the brake.

Title: Npa split management in intelligent network environment
Inventor: SAMBA AUGUSTINE SYLVESTER
IPC: H04Q3/00
Filed: 1999-08-12
Abstract: An NPA split management system and associated methods for receiving from a user descriptive instructions regarding an upcoming NPA split, and responsively updating components of the Intelligent Network to reflect corresponding changes in the NPA codes assigned to lines, subscribers, services, etc. A user interface operating in conjunction with a Service Management System allows the user to declare an NPA split and define its characteristics, including the old NPA code, the new NPA  code, the central office codes to be "transferred" to the new NPA, and the dates of beginning and end of the permissive dialing period (PDP). The SMS contains indicia corresponding to SMS-managed databases, or tables, records, or fields thereof, which definitively specify whether the data contained therein is affected by an NPA  split.    The SMS determines which items require updating to the new NPA code, and on which components the affected databases or services reside. The SMS transmits to each affected Intelligent Network component instructions to update the affected databases (or other items) by replacing the old NPA code with the new NPA  code. The Intelligent Network component executes the update instruction and installs a translation table entry. When transactions arrive during the PDP, the Intelligent Network component translates mentions of the old NPA to the new NPA before providing the requested service, as the updated database no longer has references to the old NPA.

IPC: A61B6/03
Filed: 1998-06-19
Abstract: A method of and system for performing intravenous tomographic digital angiography imaging which combines the principles of intravenous digital angiography with those of cone beam volume tomography for generating a direct, unambiguous and accurate 3-D reconstruction of stenosis and other irregularities and malformations from 2-D cone-beam tomography projections is disclosed in which several different data acquisition geometries, such as a circle-plus-arc data acquisition geometry, may be utilized to provide a complete set of data so that an exact 3-D reconstruction is obtained. Only a single IV contrast injection with a short breathhold by the patient is needed for use with a volume CT scanner which uses a cone-beam x-ray source and a 2-D detector for fast volume scanning in order to provide true 3-D descriptions of vascular anatomy with more than 0.5 1p/mm isotropic resolution in the x, y and z directions is utilized in which one set of cone-beam projections is acquired while rotating the x-ray tube and detector on the CT gantry and then another set of projections is acquired while tilting the gantry by a small angle. The projection data is preweighted and the partial derivatives of the preweighted projection data are calculated. Those calculated partial derivatives are rebinned to the first derivative of the Radon transform, for both the circular orbit data and the arc orbit data. The second partial derivative of the Radon transform is then calculated and then the reconstructed 3-D images are obtained by backprojecting using the inverse Radon transform.
