Title: Cardiac gating method and system
Inventor: HAIGNEY MARK C
IPC: A61B5/296
Filed: 2002-11-01
Abstract: The invention provides new materials and devices for EKG gating and defibrillation that alleviate problems in the art. Embodiments of the invention utilize special electrodes (120,130) of certain dimensions and made form materials that can generate trigger signals or transmit pulses more reliably and/or with less interference to other diagnostic procedures. The electrodes (120,130) and systems improve the amplitude and overall reliability of detecting EKG signals. The improved signals enable more reliable detection of a true cardiac phase and improved cardiac gating. Thus, embodiments of the invention lead to improved image quality, more accurate imaging of cardiac and intrathoracic/upper abdominal structures and improved referencing of systemic arterial blood flow for blood flow measurement within the chest and elsewhere in the body, including, for example, the extremities.
Patent CA-2464921-A1 (CA)
Inventor: SHIMIZU YOSHIHIRO
IPC: H02H7/085
Filed: 2004-04-20
Abstract: A detector, that prevents erroneous detection of a foreign object caught in a window glass when the engine of a vehicle is being operated and when the engine is stopped using a relatively simple control method. The detector includes a pulse sensor for detecting rotational speed of a motor. A microcomputer calculates a cycle difference sum based on the rotational speed of the motor. The microcomputer compares the cycle difference sum with a obstruction determination threshold to determine whether a foreign object has been caught. The microcomputer detects whether the engine is stopped. When detecting that the engine is stopped, the microcomputer changes the obstruction determination threshold so that the probability of the microcomputer determining that a foreign object has been caught is lower than that when the engine is being operated.

Title: Thermal process for treating hydrocarbon-contaminated drill cuttings
Inventor: SZYMOCHA KAZIMIERZ S
IPC: B09C1/06
Filed: 2003-02-10
Abstract: Hydrocarbon contaminants in drill cuttings generated in an oil drilling operation are removed by mixing the drill cuttings with an agglomerant (124) to produce a pre-treatment mixture (126); heating (140) to vaporize the hydrocarbon contaminants under a condition in which vapor entrainable particles of the drill cuttings are agglomerated by the agglomerant, and caking of drill cuttings is inhibited; drill cuttings having a reduced content of the contaminant are removed (180), and vaporized hydrocarbons having a reduced content of vapor entrainable particles are recovered (160). In this way, the particulate content of vapors escaping from the drill cuttings is reduced.
