| 20090299154 | OPTICAL SENSOR DEVICE AND IMAGE PROCESSING UNIT FOR MEASURING CHEMICAL CONCENTRATIONS, CHEMICAL SATURATIONS AND BIOPHYSICAL PARAMETERS - Optical sensor devices, image processing devices, methods and computer readable code computer-readable storage media for detecting biophysical parameters, chemical concentrations, chemical saturations, vital signs and physiological information such as a malignant condition are provided. In some embodiments, the optical sensor includes an array of photodetectors, where each photodetector is configured to detect a spectrum of light. In some embodiments, the image processing device receives a live still or video electronic image, or alternatively, the electronic image is provided from an electronic storage media. Exemplary physiological parameters include but are not limited to a pulse rate, a biophysical or physiological property of skin, a cardiovascular property, a property related to an organ such as the liver or the kidneys, and a temperature fluctuation. In some embodiments, the physiological parameter is indicative of a malady including but not limited to an autoimmune disease, a cancer, a nutritional deficiency, a malignant condition of bone marrow, a present of an infectious microbe such as a fungus, a present of hepatitis, and a cardiovascular disorder a pulmonary disorder. Exemplary chemical concentrations include but are not limited to a chemical saturation, a pH level, a pH level in blood vessels such as capillarys or in skin, a glucose level such as a blood glucose level, a urea nitrogen level such as a blood urea nitrogen level, a CO2 level such as a blood CO2 level or a CO2 saturation level, and an oxygen level such as a blood oxygen level or a blood oxygen saturation level. In some embodiments, the biophysical parameter, physiological parameter or chemical concentration is obtained from reflecting light from tissue from a mammalian subject. Alternatively one or more of these parameters are detected from a food item such as food tissue, a consumable beverage such as an alcoholic beverage, a dairy product, wine, a baked good, a fruit and a vegetable. Exemplary parameters related to food items include but are not limited to a parameter indicative of cooking or spoilage, a pH, a concentration of an antioxidant, and a concentration of an anti-inflammatory agent. | 12-03-2009 |
