  • Publication number: 20200300002
    Abstract: The invention relates generally a device that authenticates a user, operator, or object using multiple factors, thus decreasing the likelihood of unauthorized use. These factors preferably are independent from each other and difficult to defeat. By combining a mechanical key with a number of physically unclonable functions (PUF), the resulting system may be impossible to duplicate or defeat. The addition of the PUF can be deployed to mechanical keys or RFID's of different types without reducing the functionality of the first factors operation.

  • Publication number: 20200300935
    Abstract: A physically unclonable function is an object that has characteristics that make it extremely difficult or impossible to copy. An array of randomly dispersed hard (magnetized) and soft (non-magnetized) magnetic particles that may be conducting or nonconducting that are disbursed in a binder create a particular magnetic field or capacitive pattern on the surface. This surface magnetic field and capacitive variations can be considered to be a unique pattern similar to fingerprint. The Hall effect prism is a sensor that measures the effects of these patterns by sensing the deformation of currents or electric potential flowing within or around a resistive substrate material that exhibits a substantial Hall effect coefficient.

  • Publication number: 20200304324
    Abstract: Wine and liquor bottles have a shrink-wrap seal, or other type, that is applied to the cap/cork end of the bottle. This seal material can be loaded with randomly magnetized particles, such as flakes of an alloy of neodymium, iron, and boron (“NdFeB”). The randomly magnetized particles provide a unique unclonable magnetic fingerprint to the bottle. The magnetic field may be recorded for one or more circumferential bands around the surface of the bottle's neck and used as a magnetic fingerprint to authenticate the bottle. Authentication can be performed by inserting the bottle in an appropriate fixture, which measures the magnetic fingerprint.

  • Publication number: 20190369174
    Abstract: A system for use in authentication processes is described comprising a physical unclonable function (“PUF”), a substrate, a plurality of magnetized particles randomly dispersed in the substrate, a PUF reader constructed using multiple discrete magnetometer chips that have magnetic field sensors, placed on a circuit card in an array with a sufficient center to center spacing between sensing elements of adjacent magnetometer chips, wherein the PUF reader measures the magnetic field data at multiple locations in close proximity to the magnetized particles. The measured magnetic field data may be compared to previously enrolled data to assess authenticity.

  • 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: 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.
