  • Patent number: 9204840
    Abstract: A method of calibrating glucose monitor data includes collecting the glucose monitor data over a period of time at predetermined intervals. It also includes obtaining at least two reference glucose values from a reference source that temporally correspond with the glucose monitor data obtained at the predetermined intervals. Also included is calculating the calibration characteristics using the reference glucose values and corresponding glucose monitor data to regress the obtained glucose monitor data. And, calibrating the obtained glucose monitor data using the calibration characteristics is included. In preferred embodiments, the reference source is a blood glucose meter, and the at least two reference glucose values are obtained from blood tests. In additional embodiments, calculation of the calibration characteristics includes linear regression and, in particular embodiments, least squares linear regression. Alternatively, calculation of the calibration characteristics includes non-linear regression.

  • Patent number: 7672897
    Abstract: In accordance with the present invention, a method and system of communal purchasing is disclosed. The preferred embodiments describe a community purchase model where a product can be purchased a particular price only if enough buyers are willing to purchase at that price. The preferred embodiments pool together the collective buys for a product to get a better price than if an individual buyer was to purchase the product by himself/herself. Therefore, a fixed “discount” price is used to collect a number of buys, wherein the number of buys is recorded in a specific product record and the transaction to purchase the product is consummated if the number of buys for the product reaches a minimum number of buys. Moreover, further embodiments obtain a pre-payment or a guarantee for payment for the product while collecting buys for the product.

  • Publication number: 20080021256
    Abstract: A method and system of detecting a disease state in a targeted organ is described using nuclear medicine techniques. In preferred embodiments, a radiotracer with specific uptake for diseased portions of the targeted organ is administered to a patient. A gamma ray counter with at least one gamma ray detector is used to count gamma rays emitted by the radiotracer. By placing the gamma ray detector over the location of the targeted organ, the gamma ray counter can provide a quick yes or no answer on whether the disease state exists in the targeted organ.

  • Publication number: 20070170073
    Abstract: A method and program prevents a user from bypassing a limit placed on a specified operating life of a sensor by disconnecting and reconnecting the sensor. The present invention checks a characteristic of the sensor to see if the sensor is used prior to the connection of the sensor, and rejects the sensor if the sensor is determined to have been used before. The process of checking the characteristic of the sensor involves performing an Electrochemical Impedance Spectroscopy (EIS) procedure and calculating an impedance value. The impedance value can be compared to various threshold values for a variety of purposes including the determination of age, condition, hydration, and stabilization of the sensor.
