摘要： In various embodiments, applicants' teachings are related to an active guarding circuit and method for reducing parasitic impedance signal loading on a signal-transmission channel that is shunted by a parasitic impedance. The presence of an electrical signal on the signal-transmission channel causes a leakage current to flow through the parasitic impedance. In various embodiments, the circuit comprises an amplifier and an impedance, one terminal of the impedance is coupled to the signal-transmission channel. The input of the amplifier is coupled to the signal-transmission channel and the output is coupled to the other terminal of the impedance so as to cause a compensation current to flow through the impedance. The gain of the amplifier and the value of the impedance are selected so that the compensation current has a magnitude substantially equal to the leakage current magnitude.

摘要： The present invention relates to a system and method for delivering oxygen for breathing at a higher concentration than found in normal air and therapeutic applications of such a system and method, which improves on the limitations of the prior art by reducing and practically eliminating the waste of oxygen gas. The main benefit of this approach is a reduction in the amount of oxygen required which may result in secondary benefits such as simplifying the logistics of acquiring and storing oxygen, reducing cost, improving system portability, and allowing for the use of low-flow sources such as an oxygen concentrator instead of only using high-flow sources such as tanks of compressed oxygen.

摘要： A method for detecting and diagnosing disease states in a body part is described. The method starts with a preparatory step of modeling the body part as a grid of many finite elements, then calculating the effect of the electrical property of each finite element on the voltage between two electrodes when a known current flows between corresponding electrodes through the body part. This is termed the weight (influence) of the element. With this baseline information, electrical impedance measurements made at the plurality of electrodes on the periphery of the body part can be used in a diagnostic module to calculate a Weighted Element Value (WEVal) for each element. In a preferred embodiment of invention, the difference in WEVal magnitude between corresponding elements of homologous body parts serves as an indicator of the presence of disease.

摘要： A system and method for diagnosing the possibility of disease by making electrical measurements in one of a first body part and a second substantially similar body part are described. The present invention balances out differences between homologous body parts that are due to natural factors unrelated to disease, such as differences in size or symmetry between left and right breasts. Once data are prebalanced, statistical analyses can be performed on the data to diagnose disease. The system includes a normalizing module for obtaining a normalizing factors database from a screening population group to account for differences in spatial separation of impedance measurements. Once a set of normalizing factors is obtained, a prebalancing factor can be obtained that can further be used to adjust raw electrical measurements. Normalizing factors are applied to a smaller subset of measurements that are likely to better represent the body part as a whole. This set of measurements is reduced further by eliminating a set of the measurements that can be biased by a presence of a disease in a body part. The remaining measurements for each body part are then averaged to obtain an overall measure of a body part electrical property. The quotient between these measures is then used to adjust raw measurements. The adjusted measurements remove the imbalance that might exist due to natural differences between body parts. Adjusted measurements are then used as an input to other methods to obtain more accurate disease diagnostics.
