  • Systems and methods for non-invasive determination of blood pressure
    Patent number: 8628477
    Abstract: Methods and systems for determining blood pressure from a pressure signal are disclosed. A patient's blood pressure may be determined by analyzing features of a wavelet transformation of a pressure signal obtained during an occlusion procedure. Ridges in a scalogram of the transformed signal may be identified and used to determine an envelope of a pressure oscillation signal, to which oscillometric blood pressure determination techniques may be applied.

  • ANGLE DISTRIBUTION TECHNIQUE FOR ANALYZING A PHYSIOLOGICAL SENSOR SIGNAL
    Publication number: 20130296659
    Abstract: The present disclosure relates generally to patient monitoring systems and, more particularly, to signal analysis for patient monitoring systems. In one embodiment, a method of analyzing a detector signal of a physiological patient sensor includes obtaining the detector signal from the physiological patient sensor, and determining a ratio of the signal between two or more channels. A distribution of the angles between the points of the ratio over time may be used to determine a true ratio or a ratio of ratios for use in the determination of a physiological parameter.

  • Systems and methods for detecting pulses
    Patent number: 8574162
    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 IDENTIFYING PORTIONS OF A PHYSIOLOGICAL SIGNAL USABLE FOR DETERMINING PHYSIOLOGICAL INFORMATION
    Publication number: 20130289413
    Abstract: A patient monitoring system may determine portions of a PPG signal that correspond to artifacts, to a baseline shift that exceeds a threshold, or to a pulse-to-pulse variability that exceeds a threshold. The patient monitoring system may identify a contiguous portion of the PPG signal that does not include the determined portions. The contiguous portion of the PPG signal may be used to determine physiological information.

  • Systems and methods for maintaining sheave grooves
    Patent number: 8545135
    Abstract: A test kit for unevenly worn sheave grooves, a tool for regrooving sheave grooves that are found to be unevenly worn, and a method for testing for and maintaining the sheave grooves utilizing the test kit and tool. The test kit includes magnetic standards which adhere to a sheave beneath the portion of the sheave touched by the ropes, facilitating testing without having to unrope the sheave. Unevenly worn sheave grooves are visually ascertained by holding a straightedge adjacent to the magnetic standards. The regrooving tool includes a shank that can be received by a stand set up next to the sheave, a body attached to the shank, and an interchangeable cutting insert received by the body that is inserted in the sheave groove. When the sheave is rotated, the sheave groove is ground by the cutting insert, with each groove being ground sequentially until all grooves are again uniform.

  • SYSTEMS AND METHODS FOR NON-INVASIVE CONTINUOUS BLOOD PRESSURE DETERMINATION
    Publication number: 20130253341
    Abstract: According to some embodiments, systems and methods are provided for non-invasive continuous blood pressure determination. In some embodiments, a PPG signal is received and locations of pulses within the PPG signal are identified. An area within a particular pulse is measured. The area may be of just the upstroke, downstroke or the entire pulse. The area may be measured relative to a time-domain axis or a baseline of the pulse. The pulse may be split into multiple sections and the area of each section may be measured. The area of one portion of the pulse may correspond to systolic blood pressure while the area of another portion may correspond to diastolic blood pressure. Empirical data may be used to determine blood pressure from the measured area by applying calibration data measured by a suitable device.

  • HOLE SAW AND GUIDE
    Publication number: 20130209187
    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 DETERMINING PHYSIOLOGICAL INFORMATION USING AUTOCORRELATION WITH GAPS
    Publication number: 20130172686
    Abstract: A patient monitoring system may receive a physiological signal having gap portions in the received data. The gap portions may be identified and a plurality of morphology metric signals may be modified based on the identified gap portions. The morphology metric signals may be modified based on the identified gaps, and a combined autocorrelation sequence may be generated based on the modified morphology metric signals. The combined autocorrelation sequence may be used to determine physiological information.

  • Elevator life safety gate
    Patent number: 8469155
    Abstract: A gate below an elevator car which prevents access to an elevator hoistway. The gate slidably mounts behind a toe guard and retracts upwardly if the bottom of the gate encounters a person, object or the floor of the elevator pit during downward travel of the elevator. The gate latches when fully retracted so that it may be out of the way during maintenance. A microswitch is wired into the emergency stop circuit that engages when the gate is latched. A trip wire defining the bottom edge of the gate is also wired into the emergency stop circuit, so that the elevator will stop its downward travel if it encounters an obstruction. Rubber bumpers on the bottom edge of the gate cushion impact to people or objects who happen to be below the elevator car and are struck by the gate during downward elevator movement.
