| 20110231127 | Apparatus for High Precision Measurement of Varied Surface and Material Levels - An apparatus and method for measuring the level of a wide range of varied surfaces or materials housed within vessels, and for detecting contact with a solid surface within the vessel is disclosed. A high precision radio frequency admittance measuring system, using capacitance to measure levels of process materials, coupled with detection element to sense contact of the detection element with a solid surface, such as a floating roof. An active element and ground element in coaxial relationship provides means for measuring the level of process materials including water, oil, kerosene, jet fuel, gasoline. Along with detecting the level of a solid surface within the vessel such as a floating roof. One preferred application of the inventive apparatus is to provide vessel or tank overfill protection. The apparatus detection element is capable of sensing level and non-level solid surfaces. | 09-22-2011 |
| 20100030935 | Modbus Register Data Reformatting - A Modbus data protocol register formatting system and method are disclosed. The system and method provide for the Modbus communications protocol request and recall of data stored in a register in the data base native format, and the conversion of the data into a different requested format. The system and method similarly provide for the writing of data into a device register from a known variable format into the data base native format. The ability to convert the data by a format converter after recalling the data, or before storing the data, obviates the need to store or write data in different or multiple formats. The inventive method uses a modified register mapping that comprises defined mapping elements identifying the data address location, the requested data format, along with the data variable. The register mapping is fully variable to provide for a wide range of data formats and data address formats. The inventive system uses, in addition to the Modbus master and slave devices, a format converter that converts the data recalled into the requested data format, or converts the data to be written into the slave device native data format. | 02-04-2010 |
| 20090315278 | Measurement Systems Having Seals With Pressure Relief - Embodiments of systems include primary and secondary seals, and pressure-relief devices that are configured and positioned so that the secondary seals can have maximum rated capacities substantially less than those of the primary seals. | 12-24-2009 |
| 20080279044 | Ultrasonic Ranging in the Near Zone - An ultrasonic ranging device for ultrasonic ranging in the near zone. The device may include a transducer for generating an ultrasonic signal and for detecting an echo signal. The device may also include a processor for calculating the distance to a target object based on a first time period defined by a first set of ultrasonic signals when the target object is located outside the near zone and a second time period defined by a second set of ultrasonic signals when the target object is located within the near zone. The processor may also adjust the amplitude of the generated ultrasonic signal until the first set of ultrasonic signals is detected at the transducer. | 11-13-2008 |
