The book systematically introduces theories of frequently-used modern signal processing
methods and technologies, and focuses discussions on stochastic signal, parameter …

Ultrafast radiographic imaging and tracking (U-RadIT) use state-of-the-art ionizing particle
and light sources to experimentally study sub-nanosecond transients or dynamic processes …

The disclosure includes pulse oximetry systems and meth ods for determining point-by-point
Saturation values by encoding photoplethysmographs in the complex domain and …

A physiological trend monitor has a sensor signal responsive to multiple wavelengths of light
transmitted into a tissue site. The transmitted light is detected after attenuation by pulsatile …

(57) ABSTRACT A variable indication estimator which determines an output value
representative of a set of input data. For example, the estimator can reduce input data to …

The S transform, which is introduced in the present correspondence, is an extension of the
ideas of the continuous wavelet transform (CWT) and is based on a moving and scalable …

wavelengths of light transmitted into a tissue site. The transmitted light is detected after …

We discuss the basic ideas and motivations of time-frequency analysis from the point of view
of what is known, what is not, what is mathematically possible, and what is not. We address …

(57) ABSTRACT A method and an apparatus to analyze two measured signals that are
modeled as containing desired and undesired portions such as noise, FM and AM …
