Appl. No.:

12/496471

Inventors:

Alton Reich - Huntsville AL, US
Stephen Doherty - New Hope AL, US

Assignee:

Streamline Automation, LLC - Huntsville AL

International Classification:

G06F 13/12

US Classification:

710 69, 702 56, 702104

Abstract:

A high speed sensor data transfer interface is described. The interface combines a bridge circuit, carrier voltage source, first order RC high pass filter, reference power supply, Bessel filter, and high-speed analog to digital converter on a single Smart Transducer Interface Module board (STIM) to receive data from sensors. Data from the STIM is transferred to a Network Capable Application Processor (NCAP) having a microprocessor and either a Field Programmable Gate Array or a Complex Programmable Logic Device. The NCAP transfers data to a data exchange network.

Appl. No.:

12/331715

Inventors:

Alton Reich - Huntsville AL, US

Assignee:

Streamline Automation, LLC - Huntsville AL

International Classification:

B09B 1/00

US Classification:

4051295

Abstract:

A self-contained storage system for hazardous materials includes a containment envelope enclosing a storage tank containing hazardous materials and forming a containment space between the storage tank and containment envelope. Leaked material is detected by one or more sensors in the containment space and, depending on the concentration or time rate of change in concentration of the leaked material, alarms and corresponding mitigation measures are reversibly activated to remove leaked material from the containment space.

Appl. No.:

12/342423

Inventors:

Alton J. Reich - Huntsville AL, US
Stephen J. Doherty - New Hope AL, US

Assignee:

STREAMLINE AUTOMATION, LLC - Huntsville AL

International Classification:

G01N 27/406
G01N 27/26

US Classification:

2057775, 20440301, 205792

Abstract:

A sensor and method sense and quantify microorganisms and other biological materials. The sensor and method use high device temperatures to pyrolize and/or thermolyze biological materials, then gas-phase voltammetry is used to analyze the pyrolysis or thermolysis products to detect and identify the source biological material. The sensor and method are capable of differentiating between biological agents, such as pollen, bacteria, fungi, and their spores and the state of an organism such as living, diseased, or non-living. The sensor and method may operate at temperatures sufficient to be self-cleaning and self-decontaminating or at non-elevated temperatures to detect and identify combinations of volatile metabolites to detect and identify their biological sources.

International Classification:

F02K 1/08
F02K 9/52
F16K 1/00
F02K 1/15

US Classification:

60204, 60771, 60258, 251324

Abstract:

A constant volume combustion chamber, combustor, and method for constant volume combustion involve combusting a fuel in a chamber sealed by a pintle having a conical portion fitted into a conical nozzle throat and pulling the pintle away from the nozzle throat to allow combustion products to exhaust through a nozzle outlet. The shapes and surfaces of the pintle and nozzle throat provide for sealing the chamber at high pressures while resisting surface wear. Operational parameters for the combustor may be computer controlled in response to measured pressures and temperatures in the combustor.

International Classification:

C11B 1/10
C12M 1/00

US Classification:

554 8, 4353061

Abstract:

A method and system for processing algae involves the use of an ionic liquid-containing clarified cell lysate to lyse algae cells. The resulting crude cell lysate may be clarified and subsequently used to lyse algae cells. The process may be repeated a number of times before a clarified lysate is separated into lipid and aqueous phases for further processing and/or purification of desired products.
