  • SYSTEMS AND METHODS FOR IDENTIFYING PATIENT TALKING DURING MEASUREMENT OF A PHYSIOLOGICAL PARAMETER
    Publication number: 20140276165
    Abstract: A patient monitoring system may include a microphone that generates a sound signal based on sound emanated from a patient. A patient monitoring unit may process the sound signal to identify respiration information such as respiration rate and to determine whether the patient was talking. If the patient was talking, a confidence value may be calculated, which may be used to generate a respiration information value.

  • SYSTEMS AND METHODS FOR DETERMINING RESPIRATION INFORMATION FROM SEGMENTS OF A PHOTOPLETHYSMOGRAPH
    Publication number: 20140275889
    Abstract: A physiological monitoring system may determine respiration information from a PPG signal. The system may analyze the PPG signal with respect to itself by associating values of the PPG signal with values of a time-delayed version of the PPG signal to create pairs of associated values. A subset of associated values may be identified. Respiration metric values may be determined based on the subset of pairs. The respiration metric values may be amplitude values and/or time values corresponding to the subset of pairs. The respiration metric values may be analyzed using autocorrelation, cross-correlation, or other signal processing techniques to determine respiration information such as respiration rate.

    Patent number: 8838211
    Abstract: The present invention is a multi-wavelength diagnostic imager. In one embodiment, the present invention includes an apparatus and method for noninvasive evaluation of a target versus a non-target, comprising: one or more light sources having at least one emission spectra directed at the target wherein the position, orientation and intensity of light sources is varied to control near-surface reflectance and are directed at less than the entire target; and one or more detectors positioned to capture light reflected from the target into two or more spatial images of the target at two or more times, wherein the spatial images are used to distinguish between the target and the non-target.

  • Systems and methods for artifact detection in signals
    Patent number: 8827917
    Abstract: According to embodiments, a method and system for artifact detection in signals is disclosed. The artifacts may take the form of movement artifacts in physiological (e.g., pulse oximetry) signals. Artifacts in the wavelet space of the physiological signal may be removed, replaced, ignored, filtered, or otherwise modified by determining the energy within a predefined moving area of the wavelet scalogram, comparing the determined energy within the predefined moving area of the wavelet scalogram to a threshold value, and masking at least one area of artifact in the wavelet scalogram based, at least in part, on the comparison. From the enhanced signal, physiological parameters, for example, respiration, respiratory effort, pulse, and oxygen saturation, may be more reliably and accurately derived or computed.

  • Methods and apparatus for producing and using lightly filtered photoplethysmograph signals
    Patent number: 8755854
    Abstract: One or more physiological conditions of a patient can be observed by obtaining a photoplethysmograph (“PPG”) signal from the patient and by only lightly filtering that signal. The light filtering of the PPG may be such as to only remove (for example) high frequency noise from that signal, while leaving in the signal most or all frequency components that are due to physiological events in the patient. In this way, such physiological events can be observed via a visual display of the lightly filtered PPG signal and/or via other signal processing of the lightly filtered PPG signal to automatically extract certain physiological parameters or characteristics from that signal.

  • Hole saw and guide
    Patent number: 8696268
    Abstract: An apparatus for enlarging an existing hole in an object includes a separate hole saw with a center pilot shaft. A guide tube with a disk attached at one end inserts into the preexisting hole in the object and receives a bridging web with a plurality of tapered radial arms cumulatively forming a cone shape on the other end. The space between the bridging web and the disk is reduced by a threaded fitting to clamp the guide tube on the object within the existing hole. When the cone-shaped web wedges into the pre-existing hole, the guide tube is moved toward the axis of the pre-existing hole. The bore of the guide tube slideably receives the pilot member to guide the hole saw to rotate coaxially relative to the bore when cutting the second hole. A flat web may be used for non-coaxial cutting.

  • SYSTEMS AND METHODS FOR DETECTING PULSES
    Publication number: 20140058231
    Abstract: According to embodiments, systems and methods are provided for detecting pulses in a PPG signal. Local minima and maxima points may be identified in the PPG signal. Each minimum may be paired with an adjacent maximum forming an upstroke segment. Noise may be removed by comparing adjacent segments and ignoring segments that are too long or too large. Notches in the pulse may be identified and ignored by analyzing adjacent segments. Adjacent upstroke segments may be combined as a single upstroke if the lengths of adjacent upstroke segments are about the same, have similar slopes, and the end point of one segment is close to the start point of an adjacent segment. Segments having small temporal or amplitude difference relative to adjacent segments may be disregarded. The remaining segments may represent the pulse upticks. A sliding time window may be used instead to detect pulses in the PPG signal.

  • SYSTEMS AND METHODS FOR RIDGE SELECTION IN SCALOGRAMS OF SIGNALS
    Publication number: 20140016840
    Abstract: According to embodiments, systems, devices, and methods for ridge selection in scalograms are disclosed. Ridges or ridge components are features within a scalogram which may be computed from a signal such as a physiological (e.g., photoplethysmographic) signal. Ridges may be identified from one or more scalograms of the signal. Parameters characterizing these ridges may be determined. Based at least in part on these parameters, a ridge density distribution function is determined. A ridge is selected from analyzing this ridge density distribution function. In some embodiments, the selected ridge is used to determine a physiological parameter such as respiration rate.
