  • Publication number: 20200222672
    Abstract: The present disclosure relates to guidewire devices with an outer tube and a core. The distal section of the core extends into and is surrounded by the outer tube. One or more centering mechanisms are also disposed within the outer tube and are arranged to fill a portion of the annular space between the core and the inner surface of the tube. The one or more centering mechanisms thereby assist in keeping the distal section of the core axially aligned within the tube, which enables effective control of the device and minimizes undesirable whip movements of the guidewire.

  • Patent number: 10670723
    Abstract: An electronic home plate provides assistance to an umpire in determining whether a pitch results in a “strike” or a “ball.” The home plate is implemented with LEDs producing discrete pulses of infrared light beams extending vertically. As a moving ball intersects the pulses, light from the pulses is scattered and incident on photodetectors embedded in the home plate, producing a series of data points. Two stages of light compensation compensate the data points for ambient light, first by applying an offset current to a photodetector through a PNP transistor, and second by subtracting a measurement immediately before a pulse from a measurement during the pulse. A processor then fits the data points to a curve, to compute vertical and lateral positions of the ball, thereby determining whether the pitch passed within a strike zone. Other applications may similarly analyze the trajectory of other projectiles for various purposes.

  • Publication number: 20200121308
    Abstract: The present disclosure relates to interventional devices such as catheters and guidewire devices having micro-fabricated features for providing flexibility while maintaining good torquability. An interventional device includes an elongated member (500) having an arrangement of fenestrations which define a plurality of axially extending beams coupling a plurality of circumferentially extending rings. The fenestrations are arranged so that the resulting beams form a distributed, non-helical and non-linear pattern along the length of the elongated member. The pattern of fenestrations thereby minimizes or eliminates preferred bending axes.
