Cathodic Protection Methods and Apparatus

US06224743

Apparatus, compositions and methods provide cathodic protection to a structure by placing an anode layer (10) directly between the structure (22) and its underlying foundation (30). Structures contemplated to be protected in this manner include especially very large structures such as above ground storage tanks. In one aspect of preferred embodiments, the anode layer (10) comprises sheets of at least 85% aluminum […]

Cosmetic Color Determinate System

US06807297

A collector (202) captures light from source images as a field of pixels, a color analyzer (292) analyzes a proper subset (420) of the field to produce a plurality of color values, and a cosmetic analyzer then uses the color values to produce a cosmetic color determination. Another aspect of the present invention comprises a window having a light passage area, […]

Integrated Alert System

WO27002083

Contemplated alert systems provide increased functionality and interactive operation by use of subsystems that are coupled between the GUI/rules engine and the alert devices, wherein the subsystems provide for bidirectional flow of information. Therefore, in one aspect, the GUI displays functional and operational parameters of associated alert devices in real time and thus allows an […]

Lifesaver Personal Alert and Notification Device

WO27002082

Systems and methods of alert and notification transmission are contemplated in which a low-range transceiver provides an alert/notification to a plurality of users having a wearable transceiver. Most typically, the low-range transceiver (a) is located in a wide area notification zone and a trigger device provides a signal from a wide area notification device to […]

Control System Simulation Testing and Operator Training

US07162385

A requirements database and test generator generates tests for functional and field testing and generates requirements documentation, user manuals, operational procedures, instrument data sheets, instrument indices, instrument loop diagrams, validation reports, and test reports, including exception and passing reports. A portable process control simulator system which provides control system users with scenarios that mirror field […]

Irrigation Controller Using Estimated Solar Radiation

US07048204

An irrigation controller (200) receives temperature data, and at least partly derives an estimated solar radiation value from the temperature data. A regression model stored in a memory (220) of the irrigation controller (200)operates upon a data point from the estimated solar radiation to estimate an evapotranspiration rate, which is used to affect an irrigation schedule executed by the controller (200). […]

Configurations and Methods for Wave Energy Extraction

A wave energy harvester includes an element that converts forward and/or backward movement of water in a wave passing the harvester into upward and/or downward movement to thereby increase the vertical amplitude of the harvester relative to the sea floor. In most preferred aspects, the element is a hydrofoil that is coupled to the harvester. […]

Secondary Battery with Autolytic Dendrites

WO03028127

A battery (100) comprises a cell having a cathode compartment (120) that includes an element that is oxidized during charging of the battery (100), wherein the oxidized element forms a salt with an acid and thereby increases the H+ concentration in the cathode compartment (120) sufficient to promote an H+ flux into the anode compartment […]

Optical Method and Apparatus for Determining Fertility Status

WO09961891

An optical method of determining a woman’s fertility status is provided, wherein an optical system (20) has a sample receiving surface (29) and an eyepiece (28), such that the sample can be viewed in focus through the optical system (20) without altering the distance between the eyepiece (28) and the sample receiving surface (29) using […]
