Abstract: The invention provides, in some aspects, an AMCPR method and apparatus that apply a continuous flex correction where a flex correction is determined based on one or more strokes, and applied to a subsequent compressive stroke. In these aspects, for example, the AMCPR's control system determines the flex correction to a future compressive stroke based on the rail voltage and amperage applied to a motor during a prior compressive stroke, such as an immediately prior stroke or such as the penultimate stroke. As a result of using the rail voltage and amperage applied to the motor, the need for an additional sensor means, such as a force sensor, has been removed.

Abstract: An autonomous mechanical CPR device and method is disclosed for adjusting the therapeutic position of a CPR surface during a CPR session. The adjustment of the CPR surface permits the CPR surface to maintain better proximity to a victim's chest.

Abstract: A method for printing media includes accumulating post processing instructions for printed media during printing operations, recording the post processing instructions on an information device, and playing back the post processing instructions for controlling offline post processing of the printed media.

Abstract: A parallel duplex paper path device is provided for feeding a recording medium along a feed direction from a first printing device to a second printing device, which are arranged in parallel. The paper path device comprises at least two turning stations that are each assigned to one of the first or second printer. The turning stations are configured symmetrically to allow for reversing the feed direction and to allow for a device which can be assembled using standardized sub-assemblies.
