This patent application is assigned to
The following quote was obtained by the news editors from the background information supplied by the inventors: "Analyte (e.g., glucose) monitoring systems including continuous and discrete monitoring systems generally include a small, lightweight battery powered and microprocessor controlled system which is configured to detect signals proportional to the corresponding measured glucose levels using an electrometer, and RF signals to transmit the collected data. One aspect of certain analyte monitoring systems include a transcutaneous or subcutaneous analyte sensor configuration which is, for example, partially mounted on the skin of a subject whose analyte level is to be monitored. The sensor cell may use a two or three-electrode (work, reference and counter electrodes) configuration driven by a controlled potential (potentiostat) analog circuit connected through a contact system.
"The analyte sensor may be configured so that a portion thereof is placed under the skin of the patient so as to detect the analyte levels of the patient, and another portion of segment of the analyte sensor that is in communication with the transmitter unit. The transmitter unit is configured to transmit the analyte levels detected by the sensor over a wireless communication link such as an RF (radio frequency) communication link to a receiver/monitor unit. The receiver/monitor unit performs data analysis, among others on the received analyte levels to generate information pertaining to the monitored analyte levels. To provide flexibility in analyte sensor manufacturing and/or design, among others, tolerance of a larger range of the analyte sensor sensitivities for processing by the transmitter unit is desirable.
"In view of the foregoing, it would be desirable to have a method and apparatus for providing a dynamic multi-stage amplification of signals for use in medical telemetry systems such as, for example, analyte monitoring systems."
In addition to the background information obtained for this patent application, NewsRx journalists also obtained the inventor's summary information for this patent application: "In one embodiment, an apparatus including a first amplifier having at least one input terminal and an output terminal, the at least one input terminal coupled to a signal source, the output terminal configured to provide a first output signal, a second amplifier having at least one input terminal and an output terminal, the at least one input terminal coupled to the output terminal of the first amplifier, the output terminal of the second amplifier configured to provide a second output signal, a processor operatively coupled to receive the first output signal and the second output signal, where the first output signal is a predetermined ratio of the second output signal, and further, where the first output signal and the second output signal are associated with a monitored analyte level of a user is disclosed.
"These and other objects, features and advantages of the present invention will become more fully apparent from the following detailed description of the embodiments, the appended claims and the accompanying drawings.
