Abstract: A hinged product has a first section and a second section. The first section has a post extending transversely across one end thereof. The second section two co-axial apertures therein, each of the apertures having an internal wall. The post extends between and through the apertures to connect the first section to the second section. There is at least one protrusion located on either the post or the internal walls of the apertures. There is at least one rib disposed the other of the internal walls or the post.

Inventor: STYLOS LEE
IPC: A61B5/296
Filed: 2002-08-30
Abstract: Techniques "AND SYSTEM (10)" for detection and treatment of myocardial ischemia are described that monitor both the electrical and dynamic mechanic al activity of the heart to detect and verify the occurrence of myocardial ischemia in a more reliable manner. The occurrence of myocardial ischemia ca n be detected by monitoring changes in an electrical signal such as an ECG or EGM, and changes in dynamic mechanical activity of the heart. Dynamic mechanical activity can be represented, for example, by a heart acceleration signal or pressure signal. The electrical signal can be obtained from a set of implanted or external electrodes (16,18,20;22,24,26)" . The heart accelerati on signal can be obtained from an single- or multiple-axis accelerometer (88,108)" and/or a pressure sensor deployed within or near the heart. The techniques correlate contractility changes detected by an accelerometer or pressure sensor with changes in the ST electrogram segment detected by the electrodes (16,18,20;22,24,26)" to increase the reliability of ischemia detection.

Title: Bale processor with a bale drive roller driven by a hydraulic motor
Inventor: KOSOKOWSKY MURRAY
IPC: B02C1/10
Filed: 2004-03-01
Abstract: A bale processor with a processing chamber includes a manipulator driven by a drive system that includes a hydraulic motor. The hydraulic motor of the drive system drives a drive shaft with an axis of rotation offset from a driven shaft of the manipulator. A rotation transmission mechanism allows a higher torque to be applied to the manipulator than may be applied by the hydraulic motor alone and, thereby, leads to improved performance for the bale processor. Additionally, the hydraulic motor may be sized such that the peak allowable pressure of the hydraulic motor is higher than the peak output pressure of the power source used to drive the hydraulic motor.

Inventor: JABUSCH KIRBY
IPC: E21B47/04
Filed: 2004-03-30
Abstract: A device for determining a location of an interface between a first fluid and second fluid includes a non-mechanical sensor that measures a selected parameter of interest relating to the fluid surrounding the sensor ("the surrounding fluid") and a processor for processing the sensor measurements. The non-mechanical sensor measures a parameter relating to the surround fluid without physically co-acting with the surrounding fluid. Exemplary parameters such as thermal properties, electrical properties, fluid properties, and magnetic properties can be measured. The processor is programmed to process the sensor measurements to identify one or more characteristics in the measurements that can indicate the nature of the fluid being measured and thereby determine the location of the interface. The determined location can be used to operate a downhole device such as a pump, to provide real-time monitoring of well conditions, to record data for long-term reservoir characterization, or to actuate an alarm.
