Patent CA-2514259-A1 (CA)
Title: Pacemaker with av interval optimization
Inventor: WESSELINK WILLEM
IPC: A61N1/362
Filed: 2004-01-06
Abstract: A system and method for use in an implanted cardiac pacing device, whereby an optimal AV delay is determined at or near lower rate (pacing) limit (LRL) by determining measuring the variance, or instability, of the QT interval for a set of intervals. In one embodiment, asynchronous "LRL pacing" with a first programmed AV delay determines a measure of QT variance. The difference between the maximum QT and the minimum QT is expressed as QTdifference (QTD).  For each programmed AV delay the QT variance is again measured and the optimal AV delay produces minimum QTD. In another embodiment, AV delay is modulated around base values for a time. The difference between QT for the modulated AV  and for the base AV (dQT) is measured at each base value, and the optimal AV  delay corresponds to the smallest dQT.

Title: Method and apparatus for detecting communication network delays
Inventor: SMITH RALPH
IPC: H04B7/185
Filed: 2004-03-04
Abstract: A method and apparatus for detecting communication network delays. In general, messages from vehicles are time stamped, and then the time stamp is compared to a time that each message is received by a central station. A processor at the central station then determines a time difference between the time stamp and the received time. The time difference is then compared to a predetermined time. If more than a predetermined number of messages is received by the central station exceeding the predetermined time, a notification is sent to an entity, such as personnel at the central station.

Title: Paper and book support
Inventor: KENNEDY MATTHEW GC
IPC: A47B23/00
Filed: 2005-09-22
Abstract: Paper supports are required to hold up a piece of paper or a book so that the contents can be read without manipulating the paper or book. The invention supports papers and books by three (3) fingers that hold the paper or book much like a human hand would.  The fingers are shape memory elastomer in the preferred embodiment but can be made of other materials like spring steel. Once inserted the paper is held between the fingers, one finger on one side and two on the other, such that the fingers bend the paper vertically so that the top end of the paper does not curve downward which would make the paper unreadable. Likewise, books are held open by the fingers in one of two ways:  either one finger sits in the crease of the book as the other two provide a rest for the book at the outside cover, or two fingers hold the two sides of the book open as the third supports the book at the spine. The invention generally has a weighted base to support the weight of the paper or book. The paper or book can be oriented at an angle to make the task of reading more ergonomic.

Title: Multiple sensor vehicle occupant detection for air bag deployment control
Inventor: THOMPSON GREGORY T
IPC: B60N2/90
Filed: 2002-03-04
Abstract: A passenger detection system is provided. The passenger detection system utilizes an oscillation circuit that causes an antenna electrode to emit an electric field that is disrupted by the electrical characteristics of an object placed on the seat. This disruption alters the current and phase of the signal in the antenna electrode. By comparing the current flowing in the antenna electrode and/or the difference between the phase of the signal in the antenna electrode and the oscillation circuit output signal with predetermined threshold values, it is possible to detect the presence of a passenger in a reliable and inexpensive manner.      Environmental sensors are used to make the determination more accurate.   Humidity, moisture and/or grounding condition are detected and used to alter processing, values or calculations.

IPC: G06T15/30
Filed: 2004-11-29
Abstract: A system and method for creating a surface for an arbitrary segment of a three-dimensional data set are presented. In exemplary embodiments according to the present invention the method includes initially identifying a set of surface voxels of the segment. For each voxel in the set information as to which of its neighbors are inside voxels can be obtained, and the results can be utilized to determine the location and direction of a polygonal surface dividing the voxel. The surface can then be obtained by connecting all of the polygonal surfaces. In exemplary embodiments according to the present invention the polygonal surfaces can comprise triangles. In exemplary embodiments according to the present invention the surface can be displayed in either a wireframe mode or a solid mode. In exemplary embodiments according to the present invention mesh reduction can be implemented to reduce the number of polygons in the final surface. In exemplary embodiments of the present invention the volume bounded by the mesh surface can be calculated.  Additionally, if the mesh surface generated is not a closed surface, as when, for example, the segmented object has been cropped prior to generation of the mesh surface, any "holes" within it can be closed by a mesh and then the volume can be calculated.
