  • Patent number: 10973426
    Abstract: A catheter with basket-shaped electrode assembly with spines configured for hyper-flexing in a predetermined, predictable manner when a compressive force acts on the assembly from either its distal end or its proximal end. At least one spine has at least one region of greater (or hyper) flexibility that allows the electrode assembly to deform, for example, compress, for absorbing and dampening excessive force that may otherwise cause damage or injury to tissue wall in contact with the assembly, without compromising the structure and stiffness of the remaining regions of the spine, including its distal and proximal regions. The one or more regions of greater flexibility in the spine allow the spine to flex into a generally V-shape configuration or a generally U-shape configuration.

  • Patent number: 8271211
    Abstract: An in-situ gas flow measurement controller measures the temperature and rate of pressure drop upstream from a flow control device (FCD). The controller samples the pressure and temperature data and applies the equivalent of a decimating filter to the data to produce filtered data at a slower sampling rate. The controller derives timestamps by counting ticks from the sampling clock of the A/D converter that is sampling the pressure at regular intervals to ensure the timestamps associated with the pressure samples are accurate and do not contain jitter that is associated with software clocks. The controller additionally normalizes the temperature reading to account for power supply fluctuations, filters out noise from the pressure and temperature readings, and excludes data during periods of instability. It calculates the gas flow rate accounting for possible non-linearities in the pressure measurements, and provides the computed gas flow measurement via one of many possible interfaces.
