  • Patent number: 10860746
    Abstract: A system and method is provided for a cryptographic primitive and authentication protocol comprised of micro-cavity resonators at optical wavelengths. A micro-cavity resonator is illuminated with an optical challenge signal and the cavity returns an output response that is dependent on the input signal. Digital signal processing is performed on the output signal to generate a corresponding digital representation. This process is repeated for variations of the input signal with its digital output being stored in a database. A user or object claiming an identity presents a token to the system. The system selects a subset of the available challenge-response pairs and presents the challenges to the token. The system compares the digitized responses with the original responses expected for that token. The system will approve or deny the claimed identity corresponding to the presented token.

  • Patent number: 10124962
    Abstract: A roll-formed steel slat for use in a reciprocating floor slat conveyor system. The roll-formed steel slat is formed in a manner so as to have an upper, load-carrying surface, and a pair of downwardly depending side legs. Each side leg terminates in a foot. One foot is vertically offset from the other to provide a “hold-down” function that prevents the slat from vertically rising as the slat reciprocates back-and-forth.

  • Publication number: 20180222684
    Abstract: An all-aluminum cross-drive member for a drive unit assembly that is used to reciprocate floor slats back and forth in a conveyor system, The cross-drive member is extruded or milled from a single piece of aluminum, One side of the member carries connecting pieces for linking the member to floor slats, with the member driving the floor slats back and forth as the member is likewise moved lengthwise in back and forth movement, The other side of the member has stiffening ribs that extend lengthwise for giving the member sufficient stiffness to carry loading forces in lieu of the steel cross-drives used in the past.

  • Patent number: 9323284
    Abstract: There is set forth in one embodiment an apparatus and method for imparting a phase shift to an input waveform for output of a converted waveform. In one embodiment, a phase shift can be provided by four wave mixing of an input waveform and a pump pulse. In one embodiment, there is set forth an apparatus and method for generating a high resolution time domain representation of an input waveform comprising: dispersing the input waveform to generate a dispersed input waveform; subjecting the dispersed input waveform to four wave mixing by combining the dispersed input waveform with a dispersed pump pulse to generate a converted waveform; and presenting the converted waveform to a detector unit. In one embodiment a detector unit can include a spectrometer (spectrum analyzer) for recording of the converted waveform and output of a record representing the input waveform.
