  • Patent number: 12213766
    Abstract: A method for synchronizing operation of a heart assist pump device to a patient's cardiac cycle includes obtaining a signal from a motor of a heart assist pump device and filtering the signal to remove noise. The method also includes determining a speed synchronization start point at which time the motor of the heart assist pump device will begin a change in speed of operation based on the filtered signal. The method further includes modulating a speed of the motor of the heart assist pump device to a target speed at the speed synchronization start point, thereby synchronizing the change in speed of operation with a patient's cardiac cycle.

  • Patent number: 6726395
    Abstract: A collapsible support such as a post includes two sections interconnected via first and second threaded joint units. The first joint unit includes a first male screw member engageable with a female screw of one of the sections, a first engaging end face formed at one end of the first male screw member, and a stem projecting outward axially from the first engaging end face. The second joint unit includes a second male screw member for engaging a female screw of the other section, which is sleeved rotatably around the stem and has a second engaging end face confronting the first engaging end face. A clamp member mounted on the stem clamps together the first and second male screw members. The first and second male screw members are interlockable via the first and second engaging end faces. A resilient member mounted on the stem permits the first and second male screw members to disengage from each other for adjustment of the angular positions of the two sections.
