Abstract: Magnetic keys having a plurality of magnetic plates are disclosed. The location and orientation of the magnetic plates are controlled to generate magnetic fields that are of sufficient strength to be reliably read and sufficient complexity to be difficult to counterfeit. The magnetic keys are located on imaging-device supply items along with non-volatile memory devices containing measurements of the magnetic fields that are digitally signed. These supply items are difficult to counterfeit. Other devices are disclosed.

Abstract: A method for forming a Z-directed component for insertion into a mounting hole in a printed circuit board according to one example includes filling a first cavity having a tapered surface with a body material. A first layer of a constraining material is provided on top of the first cavity and has a second cavity having a width that is smaller than the first cavity. The second cavity is filled with the body material. Successive layers of the constraining material are provided on top of the first layer of the constraining material. Cavities of the successive layers of the constraining material are selectively filled with at least the body material to form layers of the main body portion of the Z-directed component. The constraining material is dissipated to release the Z-directed component from the constraining material and the Z-directed component is fired.

Abstract: A Z-directed capacitor according to one embodiment includes a body having top, bottom and side surfaces, a cross-sectional shape that is insertable into a mounting hole in a printed circuit board, and a plurality of stacked support members. Each support member includes an annular plate mounted on a surface thereof. A first conductive side channel and a second conductive side channel are formed in the side surface and extend along a top-to-bottom dimension of the body. A first set of the annular plates electrically contact the first conductive side channel but not the second conductive side channel and a second set of the annular plates electrically contact the second conductive side channel but not the first conductive side channel. A third conductive side channel is formed in the side surface, extends along the top-to-bottom dimension of the body and is electrically separated from the annular plates.

Abstract: A method for detecting electrostatic discharge (ESD) events in an imaging device includes scanning a target placed in a scanner to create a scanned image of the target. The scanned image has a plurality of scan lines with each scan line having a number of pixels or samples. For each of the plurality of scan lines, a determination is whether or not the number of pixels or samples of the scan line matches a respective predetermined number of pixels or samples, the predetermined number of pixels or samples being based upon a resolution setting of the scanner. Upon determining that the number of pixels or samples of the scan line does not match the predetermined number of pixels or samples, a count value is incremented. The count value is used as a healthcheck data to indicate at least one ESD event has occurred in the imaging device.
