Abstract: Measuring, controlling, and automating inventory of product stored in a collapsible tank. An interface device can interact with a sensor installed at the collapsible tank and a metering device, such as a flow meter, to generate a strap table for the collapsible tank. The strap table can include entries that correlate a process value measured by the sensor to a volume of product corresponding to that process value. Current volume of product stored in the collapsible tank can be determined by comparing a current process value to entries in the strap table or by an interpolation process. The interface device can generate an updated strap table based on a relaxation curve to account for settling of the collapsible tank. The interface device can synchronize data with a host device, such as a personal computer or handheld computer, that includes software for tracking inventory in collapsible tanks.

Abstract: An electronic fueling data acquisition and wireless communications delivery system. The unit is mounted on Aircraft Fueling Vehicles and Aircraft Fuel Servicing Hydrant Vehicles (Hydrant Vehicles) and is hardwired to an external pulse transmitter. The pulse transmitter transmits pulse signals proportional to the volume of fuel that is being pumped. A software configurable hardware filter attenuates the input signal which is then counted by a pulse accumulator. When fueling ceases, the application software can convert the pulse signal values to an equivalent volumetric total. The information can then be wirelessly communicated to other devices without the need for maintaining paper hard copies.

Abstract: A fueling agent operates a fueling agent client device for collecting and generating transaction data relating to a fueling transaction. The fueling agent client device transmits the transaction data to a fuel management server, for example, via a wireless communications link. The fuel management server stores the transaction data in a transaction record. The transaction data includes final fuel load data indicating an amount of fuel dispensed during the fueling transaction. Selected transaction data is retrieved from the transaction record and is delivered to a data communications system for transmission to a receiver. The receiver may be in the cockpit of an aircraft. An aircraft data communication system may be a digital data link system for transmitting data to and from the aircraft via VHF radio, such as ACARS. The fuel management server may communicate with an aircraft data communication system directly, or indirectly via an airline computer system.

Abstract: A method and system integrates the monitoring of system components and detecting errors or potential problems (or both) in components of bulk fuel distribution facilities. Generally, the method and system includes a diagnostic support module for identifying what stand alone software modules, what fuel hardware, and what software interfaces/drivers associated with the fuel hardware are present in a bulk fuel distribution facility. After the diagnostic support module identifies the unique system components of a particular bulk fuel facility that can include software and fuel hardware, the diagnostic support module can perform system checks of the system components to determine if any system components are missing or if errors or potential problems (or any combination thereof) may exist in a particular bulk fuel distribution facility. The system checks performed by the diagnostic support module can include comparing information collected from the system components against a predetermined set of validation rules.

Abstract: A level transmitter can generate a level measurement signal according to the position of a float that follows fluid level in a tank. The transmitter can comprise an optical encoder with a patterned disk that is linked to the float so that fluid level change produces disk rotation. An array of optical sensors positioned on one side of the disk can read reflective and absorptive patches attached to the disk's surface to identify disk position and disk rotation. One or more of the sensors can collect a signal from a reference area of the disk. Circuitry can compare the signals output by each data sensor to the reference signal to enhance binary classification of each acquired data signal. The transmitter can operate in multiple encoding modes, each of which can provide a level of redundancy.

Abstract: A fuel management server creates a primary transaction record for a primary fueling agent assigned to a fueling transaction and a secondary transaction record for each secondary fueling agent assigned to the fueling transaction. Each fueling agent interacts with a fueling agent client device to collect fueling transaction data to be stored in the transaction records. Certain transaction data collected by the secondary fueling agent is shared with the primary fueling agent. The primary transaction record stores final fuel load data indicating the amount of fuel dispensed from a primary fueling vehicle and an aggregate amount of fuel dispensed during the fueling transaction. The secondary transaction record stores final fuel load data indicating the amount of fuel dispensed from a secondary fueling vehicle during the fueling transaction. Selected portions of the primary transaction record and the secondary transaction record may be accessed for purposes of reporting and presentation.

Abstract: An error-compensated temperature measurement system has a temperature sensor, an amplifying circuit and a compensation circuit for compensating non-linearities in the amplifying circuit of the temperature sensor. Specifically, the amplifying circuit has an analogue to digital converter exhibiting non-linearity characteristics, and the compensating circuit automatically compensates these non-linearities as well as correcting for the self-zero and self gain characteristics of the amplifying circuit.

Abstract: A reversible float assembly includes a float, an elongated flexible member, a first attachment disposed on a first surface of the float body, and a second attachment disposed on a second surface of the float body. The lower end of the elongated flexible member is connected to one of the first and second attachments. At least one guide eye connected with the float body is constructed and arranged to receive an elongated guide member to restrict movement of the body to generally vertical movement. The guide eye is disposed on the body at a position between the first attachment and the second attachment so that when the body floats on a liquid in the first orientation the guide eye is submerged in the liquid, and when the body floats on a liquid in a second orientation, the guide eye is disposed above the liquid.

Abstract: A tank gauging system includes an improved level sensor float providing positional information to a level encoder unit having two slotted disks coupled to a gaugehead which alternately admit and interrupt light to optical sensors to provide relative incremental positional change and direction information as well as an error detection capability. The light optical sensors provide two signals, which are directly compared to provide a clock signal for an up/down counter. One of the two signals is delayed and this delayed signal is directly compared against the other signal to provide a direction signal for an up/down counter. A microprocessor converts this information to absolute data and provides it to a transmitter unit. The transmitter may also be provided with data from other gauging sensors, such as an error-compensated temperature measurement of the tank contents.
