Abstract:
1. A modular apparatus for acquiring biometric data, the modular apparatus comprising: circuitry operative to receive an input signal at an input corresponding to the biometric data, the circuitry comprising at least one filter and an amplifier, the circuitry being configured to process the input signal according to an aggregate transfer function thereof and to provide a corresponding processed input signal, the biometric data being indicative of at least one of (i) biological or biomedical information of a patient acquired from one or more physiological sensors, (ii) feedback information associated with a delivery of a therapy to the patient (iii) status information for the one or more physiological sensors, or (iv) operating parameters associated with equipment used to deliver the therapy to the patient; a controller configured to provide at least one control signal to the circuitry to programmatically modify the transfer function of the modular system by setting (i) at least one filter coefficient of the at least one filter and (ii) a gain of the amplifier to facilitate acquisition of the biometric data; and a register configured for storing a digital representation of the corresponding processed signal in a predetermined number of bits assigned to store the biometric data acquired by the circuitry, the controller being configured to set the at least one filter coefficient and the gain of the aggregate transfer function so that the register accommodates a maximum dynamic range of the circuitry by fitting the biometric data in the predetermined number of bits.
