20070151185, Jul 5, 2007

Filed:

Dec 29, 2005

Appl. No.:

11/320882

Inventors:

Steven Robinson - Windham NH, US

International Classification:

E01C 11/08
E04B 1/68

US Classification:

052396040, 404067000

Abstract:

A method and structure for providing a resilient seal system in the gap or joint between adjacent construction panels utilizing a foaming expansive elastic closed-cell liquid-impermeable sealant, a backer rod and a seal. The foaming expansive elastic closed-cell liquid-impermeable sealant is first introduced to the gap or joint between the adjacent construction panels. A seal is introduced into or over the gap after the foaming expansive elastic closed-cell liquid-impermeable sealant has sufficiently cured. In alternative embodiment a backer rod is located intermediate the sealant and seal as a spacing member.

Appl. No.:

8/317383

Inventors:

Janos Kovacs - Andover MA
Steven R. Robinson - Andover MA
Wyn Palmer - Andover MA

Assignee:

Analog Devices, Inc. - Norwood MA

International Classification:

H03M 178

US Classification:

341136

Abstract:

An intrinsic R2R resistance ladder digital to analog converter (DAC) includes a plurality of matched semiconductor ladder switches, one in each of the R and 2R legs of the R2R ladder. The ON resistance of each semiconductor switch being matched to constitute the resistance ladder of the DAC; the ladder switches being operated in response to the digital signal input to the DAC; a reference circuit including a reference semiconductor switch matched with the ladder switches responsive to a reference current to generate a reference voltage; and a voltage follower circuit for monitoring the reference voltage and adjusting the current through the ladder switches to match the voltage at each ladder switch with the reference voltage for precisely fixing the DAC analog output current as a proportion of the reference current in dependence upon the operation of the ladder switches by the digital input signal.

Analog Devices, Inc. - Norwood MA

International Classification:

H03G 330

US Classification:

330279

Abstract:

A hybrid analog/digital automatic gain control gain recovery system includes a variable gain amplifier (VGA) for receiving a variable amplitude input signal; a first AGC loop includes an analog to digital converter (DAC) for receiving the analog input signal and converting it to a digital signal; a digital gain error detection circuit for detecting variations of the digital signal in a first range and generating a digital error correction signal; and a digital to analog converter (DAC) for converting the digital error correction signal to a first analog correction signal; a second analog AGC loop includes an analog gain error detection circuit, responsive to variations in the output of the VGA in a second range greater than the first range for generating a second analog correction signal; and an integrator circuit responsive to the first and second analog correction signals for providing to the VGA a control signal to adjust the gain of the VGA to accommodate variations in the input signal amplitude.

Assignee:

SCHUL INTERNATIONAL CO., LLC - Hudson NH

International Classification:

E01C 11/12
E04B 1/68
E01C 11/10

Abstract:

A system which creates a durable seal between adjacent horizontal panels, including those that may be curved or subject to temperature expansion and contraction or mechanical shear. The durable seal system incorporates a plurality of ribs, a flexible member between the cover plate and the ribs and may incorporate a load transfer plate to provide support to the rib from below, and/or cores of differing compressibilities.

- Pelham NH, US
Steven R. Robinson - Windham NH, US

Assignee:

Schul International Co., LLC - Pelham NH

International Classification:

E04B 1/68
E04B 1/94

Abstract:

A system for creating a durable water-resistant seal in the joint between adjacent panels. A durable foam-based expansion seal system provides contacting surfaces which are not planar by inclusion of extensions or second bodies and which therefore provide localized areas of higher density.

Assignee:

Schul International Co., LLC - Pelham NH

International Classification:

E04B 1/68
B32B 27/06

Abstract:

A system for creating a joint filler or seal in the gap between adjacent panels or assemblies. An expansion joint seal system includes multiple bodies of differing sizes and compressibilities, which when compressed provide water resistance and localized areas of increased density.
