Abstract: Se describe un dispositivo electr?nico que puede comunicarse inal?mbricamente con otro dispositivo electr?nico. El dispositivo electr?nico puede incluir un primer procesador configurado para controlar ?nicamente las comunicaciones inal?mbricas con el otro dispositivo, pero no las operaciones asociadas ?nicamente con el dispositivo electr?nico, un segundo procesador configurado para controlar las operaciones asociadas ?nicamente con el dispositivo electr?nico, pero no las comunicaciones inal?mbricas con el otro dispositivo, y un dispositivo de memoria conectado entre el primero y el segundo procesadores. El primero y el segundo procesadores pueden cada uno estar configurados para intercambiar informaci?n con el dispositivo de memoria separadamente y de manera independiente del intercambio de informaci?n por el otro del primero y el segundo procesadores con el dispositivo de memoria.

Abstract: A method of operating an electrochemical analyte sensor having one or more electrodes may comprise applying a time-varying input signal to at least one of the one or more electrodes, monitoring a time-varying output signal produced by the sensor in response to application of the time-varying input signal, determining a complex impedance of the sensor based on the time-varying input and output signals, and determining from the complex impedance information relating to operation of the sensor.

Abstract: One aspect concerns a technique for detecting analyte concentrations, such as glucose concentrations, in blood or other bodily fluids. This technique utilizes an electrochemical test strip that includes a mediator system that generates a linear faradic response at relatively low applied potential differences. An alternating current excitation signal is applied to blood in the test strip. The alternating current excitation signal includes a low frequency signal and a high frequency signal that has a higher frequency than the low frequency signal. The glucose concentration is determined by measuring a low frequency response to the low frequency signal, measuring a high frequency response to the high frequency signal, estimating the glucose concentration based on the low frequency response, and correcting the glucose concentration for one or more error-causing variables based on the high frequency response.
