摘要： Information derived from ECG signals and EEG signals may be employed in combination to reliably predict the onset, or to indicate the presence of, hypoglycemia in a human patient. In one embodiment, ECG and EEG signals are processed and the information derived from them is combined to determine whether a patient suffering from diabetes is undergoing a hypoglycemic event, or whether such an event is imminent. Input data from the patient or a health care provider may also be used to increase the accuracy and reliability of the system. Detection of a hypoglycemic event by the system can result in the output of an alarm signal and/or the delivery or administration of a beneficial agent such as insulin, glucagon or diazoxide to the patient. The system may be implantable, external, or a combination of external and implantable components. The control strategy of the present system is preferably microprocessor based and/or implemented using dedicated electronics. In another embodiment, the glycemic state of the patient is continuously or relatively continuously monitored and controlled by the system. The system may contain any of a number of different types of feedback control systems for monitoring the glycemic state of a patient and controlling same, such as fuzzy logic systems, adaptive systems, reinforcement learning systems, and the like.

摘要： A sensing methodology is used based on measuring a physical response from a living structure as a result of a chemical compound stimulating this structure on the cellular level. Measurement of the heat response (calorimetry) from a group of pancreatic islets of Langerhans stimulated by glucose is proposed as a glucose biosensor. A novel biosensor concept is proposed acquiring physical response from living cells or cell clusters. In this particular case, membrane impedance of pancreatic B-cells, as a result of glucose stimulated cellular metabolism is used as physical readout. This method of physical assessment is made possible by growing genetically engineered pancreatic beta cells onto a substrate equipped with a set of interdigitated electrodes (IDEs).

摘要： A method for detecting a cardiac arrhythmia from an electrocardiogram includes the steps of identifying a plurality of R-waves in the electrocardiogram during a predetermined time interval; extracting heartbeat complexes corresponding to the identified R-waves; identifying a key region within each heartbeat complex that is morphologically altered in the event of the cardiac arrhythmia; calculating a statistical measurement of an ensemble of the key regions from each of the heartbeat complexes; and determining from the statistical measurement whether the cardiac arrhythmia occurred during the predetermined time interval. An apparatus is also provided that includes a processor that is coupled to receive an electrocardiogram, and is configured in response thereof to perform the method for detecting a cardiac arrhythmia.

摘要： There is provided a telemetry system with a receiver which enables detection of pulsed high frequency data (hf) signals in a manner which suppresses noise which may be present within the high frequency bandwidth. The transmitter carrier, which may be subject to some instability, is encoded at a symbol rate which is generated at a lower frequency than the hf, but which is reliably stable. The receiver detects the phase of each received hf pulse, and generates a phase-locked signal which is synchronized to the transmitter symbol signal. The phase-locked signal in turn is used to demodulate the received pulsed signals. In a specific DSP embodiment, the phase-lock loop has a numerically controlled oscillator which has a center frequency which corresponds to the aliased phase difference between the hf carrier phase and the phase of each pulse, thereby obtaining a signal which carries information as to the exact symbol rate. This information is used either to calculate the timing of a narrow window which gates a pulse detector coincident with each next expected symbol time, or to trigger generation of a replica signal which is used in the detect circuit, thereby providing high resolution detection of the pulses and good noise rejection.

摘要： An implanted medical device may detect the onset of impaired glucose tolerance or Type II diabetes. The implanted medical device may have additional functionality. For example, the implanted medical device may be a pacemaker or a pressure monitor, but may also monitor insulin-mediated glucose uptake by processing electrical signals from the heart. An implanted medical device that monitors insulin-mediated glucose uptake may be implanted in a patient who has not been diagnosed with impaired glucose tolerance or Type II diabetes, and may give the patient early warning if these conditions develop.

摘要： A system and method for sensing and providing an indication of one or more diabetes-related blood constituents of a patient, the system being based upon an ECG sensor which processes patient ECG signals, either surface, or intracardiac or epicardial, for determining a measure of a blood constituent such as insulin or glucose, or both insulin and glucose. The system has processing capability for correlating selected parameters of the ECG signal with patient blood insulin or blood glucose, to provide the insulin or glucose level. Additionally, the system is provided with input capability for enabling the patient to input data such as the time of meal intake, which is representative of glucose intake, which data is incorporated in making a determination of patient insulin need. The system can be in a first external wearable embodiment, or in a second implantable embodiment which utilizes a pacing-type lead for picking up intracardiac or epicardial signals. In either the wearable or implantable embodiment, the output response may be simply an indication of patient insulin and/or glucose need provided by an external display, and may also include automatic control of insulin injection to the patient.

摘要： Floating and non-floating on-chip capacitors are formed by vertical walls and/or large aspect ratio deep trenches disposed in semiconductor material. By optimizing the through spacing and substrate voltage, a very small parasitic to intended capacitance ratio may be obtained. Capacitors so formed may be used as on-chip charge storage and other types of on-chip capacitors, and eliminate or reduce the number of off-chip capacitors that would otherwise be required. The deep trench capacitors find particularly efficacious application in implantable medical devices where volume, cost and electrical energy consumption must be minimized, and preferably have capacitances which range between about 10 nF and about 1000 uF.
