Patent CA-2433721-C (CA)
Inventor: FISCHELL DAVID R
IPC: A61B5/366

Abstract: Heart disease is the leading cause of death in the United States. A heart attack (also known as an Acute Myocardial Infarction (AMI)) typically results from a thrombus that obstructs blood flow in one or more coronary arteries. The extent of damage to the myocardium from an AMI is strongly dependent upon the length of time prior to restoration of blood flow to the heart muscle. Acute myocardial infarction and ischemia may be detected from a patient's electrocardiogram (FCG) by noting an ST segment shift (i.e., voltage change) over a relatively short (less than 5 minutes) period of time. The present invention is a guardian system including electrodes, a cardiosaver device having AMI detection capability and an alarm means to warn the patient that they have had an AMI or other serious cardiac event and should immediately seek medical attention. Such a warning would facilitate getting medical treatment quickly to restore blood flow to the patient's heart muscle. The present invention provides accuracy of detection by comparing a recently collected electrogram data with baseline electrogram data collected at an earlier time when the heart signals were normal. False positives are reduced by requiring multiple defections separated by a predetermined time interval. The present invention can identify and differentiate between an acute myocardial infarction, exercise induced ischemia and other anomalous cardiac conditions. In the preferred embodiment of the present invention the electrodes and the cardiosaver are implanted and the guardian system includes an external alarm system that can produce an external alarm signal and also has means to turn off the alarm.

Abstract: In a borehole logging tool (e.g., 140), the flow of conductive fluid into or out of a wellbore at the wellbore wall is detected and measured with a sensor loop (e.g., 108) proximate the borehole inner wall. The sensor loop includes a series of contiguous sensors (e.g., 129) that act as electromagnetic flowmeters and provide fluid measurements covering the entire circumference of the sensor loop. The sensor loop includes an elastic element (e.g., 124) that forces the sensor loop outward to maintain pressure along the sensor loop circumference against the interior borehole wall. The sensor loop is designed to lie at a non-perpendicular angle to the wellbore axis, and mechanical arms (e.g., 102, 103) press the top and bottom of the loop against the borehole inner wall.

Title: Mattress for adjustable bed
Inventor: GLADNEY RICHARD F
IPC: A47C20/04
Filed: 2003-09-29
Granted: 2012-12-11
Abstract: Mattresses that have a point of attachment to an adjustable bed frame that provides a pivot point about which the mattress can pivot when rising to an inclined position. In one embodiment the mattress has a pivoting member extending transversely through the mattress and provides a pivot point about which one portion of the mattress can pivot in relation to another of the mattress. By placing the member about midway through the mattress, one half of the mattress can pivot relative to the other half of the mattress. While the center point of the mattress is held in place. By pinning the member to the frame, the center of the mattress is held against the frame even when one portion of the mattress is inclined relative to the other. This prevents or ameliorates the mattress~ tendency to lift off the frame when the frame pivots into an inclined position.
