20100305885 | SYSTEM AND METHOD FOR DETECTING ADULTERATION OF FUEL OR OTHER MATERIAL USING WIRELESS MEASUREMENTS - A method includes transmitting wireless signals toward material in a tank. The method also includes receiving first return wireless signals reflected off a surface of the material and identifying a level of the material in the tank using the first return wireless signals. The method further includes receiving second return wireless signals reflected off a bottom of the tank and determining whether the material has been adulterated using the level of the material in the tank and the second return wireless signals. Determining whether the material has been adulterated could include determining a dielectric constant of the material, determining a density of the material using the dielectric constant of the material, and comparing the determined density of the material against a specified density. Determining the dielectric constant of the material could include using a time between peaks associated with the first and second return wireless signals. | 12-02-2010 |
20100241369 | APPARATUS AND METHOD FOR AUTOMATIC GAUGE READING IN AN INVENTORY CONTROL AND MANAGEMENT SYSTEM - A system includes a probe configured to be raised and lowered in a tank capable of receiving a material. The system also includes a connector coupled to the probe and having at least one type of coding encoded on the connector. The system further includes a main unit configured to raise and lower the probe using the connector, digitally capture information associated with the at least one type of coding on the connector, determine a level reading identifying a level of the material in the tank using the captured information, and wirelessly transmit the identified level reading. The main unit could also be configured to determine a confidence level or interval associated with the identified level reading and wirelessly transmit the confidence level or interval. The connector could include a tape, and the at least one type of coding could include visible markings, perforations, and/or magnetic codes. | 09-23-2010 |
