Hinde sex live video chat - Validating method classifying digitally modulated signals

One embodiment of the present invention provides a system for authenticating and individual's identity.

The system operates by receiving an identification credential from the individual, such as an ID card, that contains information about the individual including biometric data. One embodiment of the present invention provides a system for authenticating and individual's identity.

The apparatus of claim 16, wherein the received pulse waveforms correspond to output by a pulse oximeter, said apparatus further comprising means for generating a signal indicative of a heart rate of the subject; means for determining a pulse rate from the received pulse waveforms; and means for indicating that the pulse rate of the non-rejected pulse waveforms is approximately equal to the heart rate indicated by said signal.23.

validating method classifying digitally modulated signals-64

Only arterial oxygen saturation levels based on validated pulse waveforms are accepted.

The present invention may also be used to validate the heart rate and/or R-R, intervals of an ECG, and for discriminating between sleep and wakefulness in a monitored subject.1.

If the difference between the data and the sample is below a predetermined threshold, the system reports a positive identification.

Otherwise, the system reports a negative identification.

This narrow range, which may be defined empirically for each subject or established by a default setting applicable to all subjects, defines a predetermined range of systolic upstroke times indicative of valid pulse waveforms.

The systolic upstroke time of each pulse waveform is compared against the predetermined range, and pulse waveforms are deemed valid only if their systolic upstroke times are within the predetermined range.

A method for discriminating between artifactual and non-artifactual pulse waveforms for validating indicated arterial oxygen saturation levels of a subject, the pulse waveforms each being defined, at least partially, by a systolic upstroke time and a diastolic time, the method comprising:determining whether said subject is asleep or awake by classifying said subject as awake during time intervals corresponding to rejected pulse waveforms and as asleep during time intervals corresponding to non-rejected pulse waveforms.11.

The method of claim 10, further comprising the step of monitoring said subject's breathing and wherein said classifying step comprises classifying said subject as awake only when said rejected pulse waveforms persist for at least one breath.12.

An apparatus for discriminating between artifactual and nonartifactual pulse waveforms for validating indicated arterial oxygen saturation levels of a subject, the pulse waveforms each being defined, at least partially, by a systolic upstroke time and a diastolic time, the apparatus comprising:means for classifying said subject as awake during first time intervals corresponding to rejected pulse waveforms and as asleep during second time intervals corresponding to non-rejected pulse waveforms.26.
