Title: Tarpaulin holddown device
Inventor: CALLAWAY ROBERT D
IPC: E04H15/62
Filed: 1996-02-09
Abstract: A tarpaulin holddown device or retainer having a handle and a shaft, with a pointed or tapered tip at the end of the shaft. The tarp retainer has a stop member positioned along the shaft between the handle and tip, and a narrow hole extending through the shaft slightly below the stop.

Title: Method and apparatus for variable rate cardiac stimulation
Inventor: HESS MICHAEL F
IPC: A61N1/365
Filed: 1996-06-04
Abstract: A method and apparatus for variable rate cardiac stimulation is disclosed, wherein sudden drops in the rate of delivery of stimulation pulses are avoided by means of rate smoothing and peak rate support functions. In one embodiment, circuitry in a cardiac pulse generator detects atrial events and maintains an updated value of the A-A time intervals between certain atrial events.  If the preset ratio or total of these A-A intervals are found to have been shorter than the updated value by at least a predetermined amount of time, a rate smoothing function is activated wherein the rate of delivery of stimulating pulses is prevented from changing, from cycle to cycle, by more than a predetermined maximum amount.  A peak rate support function preferably employs the same updated value in the computation of "escape" intervals. Following the latest A-A interval, if that A-A interval is less than the updated value, then the updated value is used as the new escape interval.  If the latest A-A interval is greater than or equal to the updated value but less than the previous updated value, the current escape interval is used as the new escape interval. If the latest A-A interval is less than both the previous updated volume and the current updated value, the [current] value updated is used as the new escape interval, and the pulse generator enters a decay mode wherein the escape interval is gradually and incrementally lengthened to prevent sudden changes in the rate of delivery of stimulation pulses.
