US Patent:

7113229, Sep 26, 2006

Filed:

Dec 17, 2002

Appl. No.:

10/322261

Inventors:

Michael J. Willis - Powder Springs GA, US
Michael L. McGuire - Snellville GA, US
Charlie W. Clark - Robins AFB GA, US

Assignee:

Georgia Tech Research Corporation - Atlanta GA

International Classification:

H04N 5/44

US Classification:

348725, 348572

Abstract:

Disclosed are systems and methods for determining the logarithmic transfer function of a plurality of analog signals using digital circuitry components. The apparatus is a digital crystal video receiver that includes an analog-to-digital converter and a programmable logic component that determines the logarithmic transfer function of plurality of signals. The programmable logic component may include a FPGA, microprocessor, macroprocessor, combinations of discrete logic components, etc. The programmable logic component includes memory having one of a look-up table and an instruction set that enables the programmable logic component to process or calculate a signal that is logarithmically proportional to the plurality of signals. The method for determining the logarithmic transfer function of a plurality of analog signals comprises converting the plurality of analog signals to a plurality digital signals and determining the logarithmic transfer function of the plurality of analog signals via a programmable logic component.

E04B 1/58

Abstract:

Various implementations include methods and apparatuses for constructing a concrete structure. In one implementation, a structure includes a pre-cast concrete column section and a pre-cast concrete beam section. The column section includes an embedded first assembly with a threaded rod, and the beam section includes an embedded second assembly defining a channel for receiving the threaded rod. Grout is fed through a joint between the column and beam sections into the second assembly to couple the threaded rod with the second assembly. The grout is urged through the joint and the second assembly by gravity and by applying vacuum suction to a grout port defined by the second assembly. The grout port extends between the channel of the second assembly and an external face of the beam section.
