Abstract: Systems and methods for detecting and monitoring arrhythmias from a signal are provided. A signal processing system may transform a signal using a wavelet transformation and analyze changes in features of the transformed signal to detect pulse rhythm abnormalities. For example, the system may detect pulse rhythm abnormalities by analyzing energy parameters, morphology changes, and pattern changes in the scalogram of a PPG signal. Further, the system may detect pulse rhythm abnormalities by analyzing both the PPG signal and its corresponding scalogram. Physiological information, such as cardiac arrhythmia, may be derived based on the detected pulse rhythm abnormality.

Abstract: An traditional-diagnosis-bypassing method for improving a mental health patient-therapy program through incorporating in it, centrally, a patient's expressed therapy goals, including (a) accessing an electronic information system which is programmed with information-capturing and related-question-based, guiding software associated with patient-personalizing therapy planning, structuring and implementing, (b) encouraging a collaboration dialogue between patient and professional to capture information relating to the patient's mental health symptoms and associated, patient-expressed therapy goals, and collaboratively entering related dialogue information into the system, and (c) based upon such information entering, and through professional-and-patient interactive engagement with the system, and functioning expressly in a conventional-diagnosis-bypassing, question and answer mode which is bottomed centrally upon recognizing the patient's expressed therapy goals, collaboratively designing, building, and thereaft

Abstract: A system for manufacturing an airfoil includes an outer surface of the airfoil, a cavity inside the airfoil, and a collimator outside of the airfoil. The system further includes a fluid column flowing from the collimator toward the outer surface of the airfoil, and a laser beam inside the fluid column creates a confined laser beam directed at the outer surface of the airfoil. A method for manufacturing an airfoil includes confining a laser beam inside a fluid column to create a confined laser beam, directing the confined laser beam at an outer surface of the airfoil, and creating a passage through the outer surface of the airfoil with the confined laser beam.

Abstract: Methods and systems are disclosed for computing one or more continuous wavelet transforms on a dedicated integrated circuit. The systems comprise an integrated circuit having a receiver, memory, and processing circuitry. The receiver receives input data corresponding to an input signal. The memory stores information corresponding to one or more wavelet functions scaled over a set of scales. The processing circuitry is configured to compute, in-parallel, various portions of a single continuous wavelet transform of the input signal based on the received input data and the stored information corresponding to a single wavelet function computed over a set of scales.

Abstract: Systems and methods are disclosed for producing audible indicators that are based on a subject's measured blood pressure. Audible properties of the indicators are processed to represent blood pressure. For example, the duration or volume of the audible indicators may be varied based on the values of the subject's blood pressure. The audible indicators may further be varied based on the subject's blood pressure's deviation from a normal blood pressure and/or previously calculated blood pressure. For example, the audible indicators may be indicative of changes in the subject's blood pressure over time. The audible indicators representing blood pressure may be synchronized with other audible indicators that represent other physiological parameters of the subject, such as, the subject's heart rate.

Abstract: A computer-based method for presenting correlated ECG and heart-associated sound information regarding a selected subject's heart including the steps of (a) collecting subject-specific, time-related ECG and heart-associated sound information, and thereafter (b), presenting, in a common-display manner, at least portions of this ECG and sound information along with (a) a stated heart-condition interpretation derived from the information, coupled with (b) the presentation of a related, authoritative clinical-interpretation guideline.

Abstract: A method and a system for monitoring and characterizing a person's heart condition for various medically related purposes. The method includes the steps of (a) acquiring a selected person's acoustic heart signature, (b) acquiring, substantially simultaneously, that same person's electrical heart signature, (c) choosing elements of determined interest from these two acquired signatures and selectively processing and inter- and/or cross-relating such elements, and (d) employing the results of the relating step to create a heart-condition fingerprint useful in the characterization of that person's heart condition.

Abstract: An anatomy-contact sensor and related methodology for collecting at least heart-sound data. The sensor includes (a) a sensor body with an internal acoustic chamber having a mouth which is placeable adjacent, and preferably in contact with, a subject's anatomy, (b) a deflectible, preferably anatomy-contacting, preferably gas-permeable membrane spanning this mouth, and effectively sealing the chamber against through-passage in the mouth of all essentially but gas, (c) an acoustic-to-electrical-signal transducer mounted on the body and exposed to acoustic events occurring in the chamber, and (d) vacuumizing structure which is effective to hold the body in gripping contact with a subject's anatomy.

Abstract: A defibrillator having one or more redundant systems each including functionally interchangeable components from which one component is selected for current operation. Manual or automatic selection of one component in each redundant system is made to form an operational defibrillator. Preferably, such selection is based on a real-time evaluation of the operational integrity of all operational components in a redundant system. Such real-time evaluations may be performed by monitoring systems within a controller, by an external test system within or external to the defibrillator or by self-test mechanisms internal to the operational components themselves. Factors such as user preferences, default component assignment, and predetermined arrangements of operational component combinations may be included in the selection determination along with the operational integrity of each operational component.

Abstract: The flow path shroud includes a plurality of generally channel-shaped shroud segments having forward and rearward rails interconnected by a flow path section along radial innermost portions of the rails. The volume bounded by the forward and rear rails and flow path sections is unbounded at the ends and the shroud therefore is without side walls. The free ends of the front and rear rails have relief cuts such that thermal induced bowing of the front and rear rails in the axial direction limits the mechanical stress applied to the turbine casing hooks. The thickness of the front and rear walls lies in an approximately 1:1 thickness ratio with the thickness of the flow path section.

Abstract: Pile weatherstripping having rows of pile sandwiching a fin is fabricated so as to precisely locate the height of the fin with respect to the height of the pile. A travelling endless band receives webs providing the fins on opposite sides thereof with the edge of each web, which defines the height of the fin, precisely positioned on a side of the band and the other edge overhanging the edges of the band. Alignment of the webs on the band is provided either by an aligning fixture or by coining the webs to provide lines of indentations which index the webs at the edges of the band. The yarn which forms the pile is wound around the webs and the band and serves to wrap the overhanging portions of the webs around the band, or a guide may be used to facilitate wrapping of the webs around the band, prior to winding of the yarn. Backing strips are attached, as by ultrasonic welding, along the edges of the band. Then the yarn is slit without cutting into the webs.
