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.

Abstract: A system for verifying a price associated with an item in a retail environment includes a price tag having an optical member that includes an optical characteristic that modifies an amount of optical energy that leaves the optical member relative to an amount of optical energy received by the optical member, and a price tag holder including an optical sensor having an emitter and a detector. The emitter is positioned to emit optical energy onto the optical member and the detector is positioned to receive optical energy leaving the optical member. A computing device in operable communication with the optical sensor is operative to determine whether the price tag is accurate based upon a comparison between the amount of optical energy received by the detector and the amount of optical energy emitted by the emitter.

Abstract: An apparatus includes a housing having a reservoir for storing consumable material and an outlet for exiting the consumable material from the reservoir; a rotatable shaft disposed inside the reservoir and positioned along a length of the housing; and one or more magnetic members disposed within the housing and coupled to the shaft so as to rotate therewith. The one or more magnetic members generate a magnetic field and when rotating indicate information about the replaceable unit. The information is based upon the presence or absence of the one or more magnetic members relative to one or more predetermined locations for receiving a magnetic member within the housing.

Abstract: A computing device display shows an actual location of an imaging device as configured in a computing system environment. An acceptance zone about a planned location of the imaging device visually conveys to a user whether or not the imaging device exists within a predetermined distance. If not, service level or other agreements specifying the location of the imaging device can be adjusted or the imaging device can be moved into compliance with the agreements. Alerts can be broadcast upon non-compliance or if the imaging device changes location. The display can be configured to show the imaging device with geospatial coordinates, within a building, superimposed on a map, such as a building floor plan, etc. Other embodiments note computing environments, deltas between locations, and various administrative tools.

Abstract: A mobile computing device hosts an operating system and mobile applications. A calibrating application causes display of an interface for entry of administrative data regarding an asset to-be-tracked. A positioning system defines locations of the asset in geospatial coordinates. The calibrating application displays a mapping function that shows on a map an initial location of the asset. Users adjust the initial location to a proper location on the map with a hand gesture on a display surface of the mobile computing device. A delta is noted between the initial and proper locations that the calibrating application applies later during tracking of the asset to precisely establish a whereabouts of the asset in its tracking environment. Other embodiments note techniques for entering administrative data.
