Abstract: An electrophotographic printer includes a charge roller in charge-transferring relation to a photoconductive imaging portion. The printer may determine an AC voltage setpoint of the charge roller.

Abstract: A device includes a charge roller and a control portion. The charge roller is removably insertable to be in charge-transferring relation to, and spaced apart by a first air gap from, a photoconductive imaging portion of an electrophotographic printer. The control portion is to determine a size of the first air gap based on determination of a charging threshold voltage associated with the charge roller.

Abstract: One example of a display device includes a first layer and a second layer including a conductive material. The second layer is attached to the first layer such that a surface of the second layer facing the first layer is exposed along an edge of the second layer. The second layer supports an electronic paper display imageable by receiving charges on an imaging surface of the electronic paper display. The second layer is electrically coupled to a counter-electrode of the electronic paper display.

Abstract: One example of a display device includes an electronic paper display, a counter-electrode, and a floating electrode. The electronic paper display is imageable by receiving charges on an imaging surface of the electronic paper display. The counter-electrode is opposite to the imaging surface of the electronic paper display. The floating electrode is capacitively coupled to the counter-electrode.

Abstract: A single-use indicator is provided and is particularly well suited for use with a surgical catheter device. The indicator includes an absorbent filament or wick which is placed in a transparent or translucent indicator lumen of a multi-lumen catheter. The lumen is provided with at least one side port. When the catheter is inserted into a blood vessel, blood enters the indicator lumen through the side port and is absorbed by the filament, thus turning the filament red or purple in color. When the instrument is removed from the blood vessel, the stained filament is clearly visible as an indicator that the instrument has been used. Because the filament is trapped inside a lumen of a relatively long catheter, it is difficult or impossible to remove it during a remanufacturing process.

Abstract: Dual-section ultra-thin (0.1-0.8 mil) plastic produce bags having a large upper compartment with an open top boundary (fill opening) and a bottom boundary that is partially open to a smaller lower section. The bags are provided in a series on a roll enabling dispensing of each bag by unrolling and tearing along a line of perforations. Individual plastic bags are defined by lines of adjacent heat seals and perforations on a flattened plastic tube. Two elongated side straps have ends attached to the bag adjacent to the top opening so that the top opening of the bag may be closed by tying the straps together. The straps are generally trapezoidal in shape with the widest dimension of the trapezoid being 50-60% the width of the bag at the junction line of the strap to the bag. This design provides strength to the attachment of the strap to the bag in order that the straps may also be used as a handle for carrying the bag.
