Abstract: An implantable cardiac stimulator includes means for delivering a first electrical shock via implantable stimulating electrodes at a time when there is substantially no flow of blood, as determined by conventional fibrillation detection means. At least one of the stimulating electrodes is disposed in a blood flow path of the cardiovascular system. The first shock is preferably of insufficient energy level to cause defibrillation. A potential is measured as a function of time between the blood-contacting electrode and a reference electrode following delivery of the first shock to obtain a first potential equilibration function under no-flow conditions. A second therapeutic electrical shock, preferably of sufficient energy level to effect defibrillation, is delivered via the stimulating electrodes. A second potential equilibration function is measured following delivery of the second shock. The first and second potential equilibration functions are compared, and if the two functions are sufficiently different in morphology, it is determined that blood is flowing.

The unloader features a stationary support frame with an open center concept. The support frame includes three main support members joined together to form a triangular frame. Three bracing members are added to the support frame to form an interior perimeter with a generally hexagon shape that delineates the open central area. A rotating drive ring is suspended from the support frame. An electric motor drives a chain loop that engages the exterior surface of the drive ring and causes it to rotate. A gathering mechanism that includes a subframe with a telescoping tubular support is suspended from the rotating drive ring. An auger is suspended from the tubular support. The telescoping tubular support is designed to permit installation adjustment so that the silo unloader can fit into a range of silo diameters and accommodate warpage in the round shape of the silo wall. The tubular support and auger are pitched at an angle of about six degrees to facilitate the distribution and gathering of silage across the top layer of the silage. The auger is driven by an electric motor having a drive shaft in line with the auger shaft. Power is supplied to the auger motor via a collector ring. The collector ring is mounted on a tower extending from the tubular support. A double pivoting wall wheel is secured to the end of the tubular support. A hole former is also secured to the tubular support and can be automatically power driven from a central loading position to a offset storage or unloading position. An on-board winch assembly may also be provided to raise and lower the silo unloader.
