摘要： Methods and systems are described for controlling a flowrate of insulin infused into the body of a patient. An insulin infusion device infuses insulin into the body of the patient. A first sensor generates blood glucose level (BGL) data indicative of a blood glucose level of the patient. A second sensor generates autonomic nervous system (ANS) data such as heart rate data dependent on at least one parameter of the patient's autonomic nervous system. A data fusion processor receives the BGL data and the ANS data and generates an output alarm signal if a hypoglycaemic event is inferred. A flowrate of insulin of the insulin infusion device may be modified dependent on the output alarm signal.

摘要： A method and system are described for detecting a hypoglycaemic state in a patient. The patient's heart rate is monitored to provide a heart-rate signal. A time-lagged signal is determined as the difference between the heart-rate signal and a time-lagged version of the heart rate-signal. The heart-rate signal is filtered with a low-pass filter to provide a heart-rate trend. An absolute difference between the heart-rate signal and the heart-rate trend is determined to provide an absolute-difference signal. A second time-lagged signal is determined as a difference between the absolute-difference signal and a time-lagged version of the absolute-difference signal. The occurrence of a hypoglycaemic condition is inferred dependent on the time-lagged signal and the second time-lagged signal.

摘要： A method and apparatus for recognizing tissue types measures at least two separate and distinct properties of a tissue specimen using a probe tip containing electrodes coupled to circuitry that applies a measuring current and obtains values of electrical properties of the tissue such as conductivity and potential difference. An algorithm then uses the values to determine the tissue's type and condition.

摘要： A system for collecting, storing and displaying dermatological images for the purpose of monitoring and diagnosis of skin conditions and skin cancers, including melanoma. A hand-held unit illuminates a section of the patient's skin, and an imaging device generates imaging signals from light derived from a skin section. Pairs of light output ports in the hand-held unit are arranged such that their intensity distributions overlap at their half-intensity levels so that the resulting summation of their intensities has a flat central region. Three image stores are maintained, one for lesion images, one for “nearby skin” images, and one for reference-white images. The “nearby skin” images are used by the system software to automatically determine the skin/lesion border. The reference white images are used to set the dynamic range of the instrument and to compensate for lighting irregularities. Two images of the same lesion taken at different times may be displayed simultaneously so that changes in the lesion may be determined. The calibration system is designed so that image data taken on any of multiple machines built to the same specification will be corrected back to a common reference standard to ensure absolute accuracy in colour rendition.

摘要： A probe type instrument to characterize tissue type that combines optical and electrical tests in a single device capable of providing data of both types almost simultaneously from very small, e.g. 3-10 mm diameter, areas of tissue surface. Key to this approach is an instrument capable of making almost simultaneous electrical and optical measurements on the same small areas of tissue, before being moved to scan adjacent tissue areas. In the preferred operation of the system fourteen measurement cycles are performed per second and each measurement involves a complex sequence of events, including (1) three optical and fifteen electrical tissue stimulations with subsequent detection, filtering and digitization of the tissue response; (2) extraction of specific parameters from the optical and electrical signals; (3) checking for errors, and subsequent classification of the extracted parameters into various tissue type categories; and (4) feedback to the system operator. Thus on the order of 15,000 measurements are made per one minute patient examination.
