Abstract: A telemetry system is described in which a plurality of channels are coupled to a bus. A control subsystem controls the channels so that one of the channels presents to the bus during its designated time period a channel characteristic. The control subsystem interrogates in the analog domain each of the channels during its designated time period, and forms a signal representative of the channel characteristic. The control subsystem may combine one or more of the signals into a digital packet, and transmit the same via transceiver over a wireless network. The channels may be contained within a submersible enclosure and displaced at intervals along the bus, thereby forming an array for monitoring waterborne threats. The array may lie along an ocean floor, may be towed by a marine vehicle, or may suspended from a deployable buoy containing the control subsystem, transceiver, and a remote power source. The array may further comprise a defensive countermeasure deployable responsive to detecting a threat.

Abstract: Methods are disclosed for forming an antifuse that includes first and second conductive regions having spaced-apart curved portions, with a first dielectric region therebetween, forming in combination with the curved portions a curved breakdown region adapted to switch from a substantially non-conductive initial state to a substantially conductive final state in response to a predetermined programming voltage.

Lower programming voltages and currents are observed compared to antifuses using substantially planar dielectric regions. In a further embodiment, a resistive region is inserted in one lead of the antifuse with either planar or curved breakdown regions to improve post-programming sense reliability.

Abstract: Systems for preparation of a mark and authentication of a mark vis-a-vis a counterfeit mark. Emission spectra comprising intensity versus wavelength distributions are collected from a series of taggants. One or more taggants is selected from the collected emission data such that the spectra of the selected taggants are distinguishable. The selection is also based on a consideration of the emitted radiation of a substrate and a dispersive medium. The authentication system uses multivariate statistical analysis to calculate at least one measurement statistic of a mark to be authenticated and at least one statistical limit based on a series of training marks prepared by the preparation system. Authenticity of the mark is determined based on a comparison of the measurement statistic and the statistical limit.
