  • Patent number: 10171684
    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.

  • Patent number: 9984820
    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.

  • Patent number: 9814145
    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.

  • Publication number: 20150186694
    Abstract: A RFID based system, including an RFID tag to communicate with a reader and having a motion-based generator generating current upon the device being moved. When the object moves, the RFID tag is configured to transmit at least one signal to the reader using the current generated by the motion-based generator to indicate that the object is in use. The RFID tag may include an energy scavenging circuit such that the RFID tag is also capable of being interrogated by the reader and perform additional operations, independent of the motion-based generator.
