Patent CA-2433721-A1 (CA)
Title: System for the detection of cardiac events
Inventor: FISCHELL TIM A
IPC: A61B5/366
Filed: 2003-06-26
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.

Patent CA-2445443-A1 (CA)
Inventor: DYKHNE ALEXANDR MIKHAILOVICH
IPC: G07D7/12
Filed: 2001-04-26
Abstract: The invention relates to methods for recording and reading information hidde n against a visualisation and can be used for visualising hidden images (marks ) which identify an object and protect it against non authorised reproduction (falsification). The inventive method for producing and visualising an optically invisible mark consists in the following: an optically invisible image of the mark is formed on the surface of a studied object by modifying at least one area of said surface. Said image is then visualised. The surface o f the studied object (carrying the image) is pre-treated in such a way that it is mirrored prior to forming the optically invisible image of the mark. The modification is accompanied by modifying surface energy of modified areas. T he visualisation of the optically invisible image of the mark is performed by creating a metastable medium in the zone of said surface. Using said metastable medium, an optically perceived invisible image of the mark is embodied in the form of the difference of structures formed by particles of the stable phase of the metastable medium on the areas of the surface (of th e studied object) having different surface energy. Various variants of the use of metastable mediums and methods for forming the optically invisible image of the mark on thesurface of the studied object are also disclosed.
