    Abstract: A system for evaluating failure of a used mattress includes a test device and computerized test device control module. The test device includes a plunger arm, a control motor attached to a first end of the plunger arm and configured to selectively extend and retract the plunger arm, and a platen attached to an end of the plunger arm distal from control motor. The control module includes a computerized processor, operating programming to evaluate the failure of the mattress. The programming includes controlling extension of the plunger arm, monitoring firmness in the mattress based upon force applied by the platen on the mattress and displacement of the plunger arm, monitoring a threshold firmness value for comparison, comparing the threshold firmness value to the monitored firmness, and generating a result of the comparison indicating the failure of the mattress.

    Abstract: Systems and methods for controlling ink component concentration for optimizing ink for use on specific media types, such as paper or plastic, include an in-line ink delivery system for mixing and delivering ink. The ink delivery system includes a first ink supply, a second ink supply, a mixing chamber or pot, and a print head connected to a print head reservoir. The ink delivery system may be configured to mix ink according to one of stored setpoints or acquired media data for media on which ink is to be printed.

    Abstract: A device and method for the detection of the interaction between two or more objects is disclosed. The device utilizes electrical impedance spectra measured from a piezoelectric element attached to one such object. Comparison of such spectra along a range of traverse allows precise estimates of distance to be made. One useful application is the topographical mapping of a surface.
