  • Patent number: 10321831
    Abstract: Disclosed examples include heart rate monitor systems and methods to estimate a patient heart rate or rate of another pulsed signal, in which rate hypotheses or states, are identified for a current time window according to digital sample values of the pulsed signal for a current sample time window, and a rate change value is computed for potential rate transitions between states of the current and previous time windows. Transition pair branch metric values are computed as a function of the rate change value and a frequency domain amplitude of the corresponding rate hypothesis for the current time window, and the pulsed signal rate estimate is determined according to a maximum path metric computed according to the branch metric value and a corresponding path metric value for the previous time window.

  • Patent number: 10322228
    Abstract: A power injector is disclosed having power injector control logic, which in turn includes a decay constant cross-reference, for instance in the form of a data structure. Flow rate decay constant information may be stored by the decay constant cross-reference. A decay constant, which may be used by the power injector to generate an exponentially decaying flow rate for an injection, may be stored in the decay constant cross-reference in conjunction with a particular imaging unit. The decay constant cross-reference may be searched by entering a model or module number of an imaging unit to identify the corresponding flow rate decay constant to be used by the power injector.

  • Patent number: 10322287
    Abstract: Provided is a portable controller and associated method that provides a patient or caregiver the ability to recharge and alter the parameters of an implanted medical device, while allowing the patient substantially unobstructed mobility. To enable mobility, the controller may be worn on a belt or clothing. The controller also allows the patient to turn device stimulation on and off, check battery status, and to vary stimulation parameters within ranges that may be predefined and programmed by a clinician. The controller communicates with the medical device to retrieve information and make parameter adjustments using wireless telemetry, and it can send and receive information from several feet away from the implanted medical device. Charging of a battery contained in the implanted medical device is achieved via an inductive radio frequency link using a charge coil placed in close proximity to the medical device.

  • Patent number: 10271789
    Abstract: The present invention provides a method for measuring the body fat percent and fat accretion during pregnancy, which preferably utilizes a Fourier transform near infrared spectroscopy (FT-NIR) fat determination method. The FT-NIR results can be used to measure and monitor body fat percent, and used to measure the mother's fat accretion rate. A method to monitor weight gain in a pregnant subject is provided wherein the body fat percentage of the subject is maintained at a constant level during gestation, and the subject's fat accretion rate is monitored so as to follow the fat accretion rate provided by using pre-defined fat accretion determination formulae. By measurement of the body fat percent and fat accretion rates, the weight gain of a subject can be monitored and/or controlled during pregnancy.
