摘要： An amplifier-based system having pulsed output includes an amplifier for amplifying a time varying voltage signal to produce an output voltage signal. A voltage-to-current (V-I) converter converts the output voltage signal into a current signal. An output stage including a current integrator integrates the current signal to generate an integrated voltage. An amplitude to time converter generates a pulse train from the integrated voltage, wherein a timing of the pulses in the pulse train represents the original time varying voltage signal. The pulse train representation permits transmission and accurate remote reconstruction of the original time varying voltage signal, such as signals generated by electrodes implanted inside a subject, including neural signals.

摘要： A neural recording system (100) and method (400) for neural encoding is provided. The system can include an ultra-low power neural encoder (120) for compressing spikes within a neural signal (1 10) to produce a pulse train (130) and wirelessly transmitting the pulse train to a spike sorter (140).

The neural encoder can include an Integrate and Fire (IF) neuron 230 that performs spike detection and encodes at least one spike (1 12) of the neural signal. A leakiness aspect (232) and an adaptive aspect (337) can be included with the IF circuit for combining aspects of spike detection and spike sorting for suppressing noise, keeping power consumption low, and improving signal resolution.

摘要： A multi-scale spike detector for performing multi-resolution spike detection's of a signal is provided. The spike detector includes a gamma filter having cascaded low-pass filters. The cascaded filters collectively provide different cutoff frequencies, each of the filters having a respective output. One of the filters has an input, at which the signal is received. The spike detector further includes combining circuitry that combines at least some of the respective outputs of the cascaded filters. The differences formed from this combining provide a waveform representation of the input signal. The waveform representation consists essentially of spikes that occur in the signal.

摘要： The invention is a system, and method for deriving the respiratory rate of an individual from the raw, unfiltered opto-plethysmograph signal output by a standard pulse oximeter. The components of the system consist of a pulse oximeter (110), and a processor device (120) that processes the opto-plethysmograph signal output from the pulse oximeter. The raw unfiltered opto-plethysmograph signals are processed to remove the high frequency heart rate, and the low frequency components from the raw signal to generate a processed signal that contains primarily the desired respiratory variations. Several feature extraction algorithms are then applied to the processed signal to identify those peaks of the processed signal that truly represent respiratory peaks. The respiratory rate is then calculated based on the identified repiratory peaks, and averaged over a predetermined number of breaths.
