  • In-band signaling for data communications over digital wireless telecommunications networks
    Patent number: 8068792
    Abstract: An inband signaling modem communicates digital data over a voice channel of a wireless telecommunications network. An input receives digital data. An encoder converts the digital data into audio tones that synthesize frequency characteristics of human speech. The digital data is also encoded to prevent voice encoding circuitry in the telecommunications network from corrupting the synthesized audio tones representing the digital data. An output then outputs the synthesized audio tones to a voice channel of a digital wireless telecommunications network.

  • Catalytic Production of Biomakers From Biological Materials
    Publication number: 20080187907
    Abstract: An apparatus and method for detecting a biological material, such as bacterial spores (e.g. Anthrax) which reacts non-volatile biomarker precursors to volatile precursors by heating the biological material in the presence of a catalyst.

  • Automatic drying tower switching system
    Patent number: 4504286
    Abstract: In a process in which parallel dehydrating towers are utilized to remove water from a wet gas, the amount of water provided to a desicant bed contained in a drying tower during a drying cycle is determined and compared to the capacity of the desicant bed. This comparison is utilized to override control based on a moisture analyzer in such a manner that switching between the two dehydrating towers is accomplished even if the moisture analyzer fails.

  • Constant writing rate digital stroke character generator having minimal data storage requirements
    Patent number: 3952297
    Abstract: A digital character generator with minimal storage requirements for use in random access display systems. Each character or symbol is made up of patterns of straight line segments called macro-strokes. Each macro-stroke in turn is made up of a predetermined number of connected portions or micro-strokes lying in a straight line. Each micro-stroke is of substantially the same length independent of the number of micro-strokes in a macro-stroke and of the directional orientation of the macrostroke. To store a character or symbol each macro-stroke is divided into its micro-strokes and the micro-strokes resolved into X and Y components. The X and Y components are stored along with the number of micro-strokes in the particular macro-stroke. Along with this information is stored the address and memory of the next macro-stroke within the character or symbol.
