32420726, 32420712, 324652, 324655

Abstract:

A system and method for determining characteristics of a proximity sensor. According to a preferred embodiment, the admittance of a proximity sensor/cable assembly is measured at two frequencies. Assumptions about sensor characteristics and cable characteristics are made, and an admittance corresponding to the assumed characteristics is derived. The assumptions are adjusted to obtain a correspondence between the measured admittance and the derived admittance. When the assumptions have been updated a specified number of times or when a desired accuracy threshold has been met, the adjusted assumptions may be used to determine one or more sensor characteristics, such as the separation between the proximity sensor and the target object.

Abstract:

A measurement method and system in which a plurality of sensors are scattered about the system. One or more universal data concentrators are deployed in the areas where the sensors are concentrated. Each data concentrator is connected to one or more computers. Unique configuration data is provided to each data concentrator for its unique sensor type complement. Each data concentrator configures itself based on its configuration data. This allows the use of a universal data concentrator and, thus, one part number.

Abstract:

A weight and balance system for accurately determining gross weight of an aircraft. The present invention integrates tire pressure measurements with strut pressure measurements to overcome the problem associated with the friction in the strut seals, and simultaneously overcome the problem with the large number of variables associated with using tire pressure measurement to determine load (weight on wheels). An example system includes a plurality of strut pressure sensors that generate strut pressure data for landing gear struts of the aircraft and a plurality of tire pressure sensors that generate tire pressure data for tires of the aircraft. A processing device that is in data communication with the strut and tire pressure sensors determines gross weight and center of gravity of the aircraft based on the received strut and tire pressure data.

Abstract:

Systems and methods for determining center of gravity for an aircraft. An example system includes one or more load measurement devices that generate one of nose gear or main gear weight information and a processing device that determines center of gravity of the aircraft based on previously received gross weight information and the generated nose or main gear weight information. The number of gear sets with load measurement devices is one less that the total number of gear sets having distinct longitudinal positions along a fuselage of the aircraft. The processing device further determines center of gravity based on temperature and/or pitch attitude information. The system includes a user interface that allows a user to enter the gross weight information that might be included in a flight manifest or a load and trim sheet and/or a communication component that receives the gross weight information from a ground-based system.

International Classification:

US Classification:

73231R

Abstract:

A fluid flowmeter, of a type including a housing and a fluid flow measurement assembly rotatable therein which is driven by a turbine, is described in detail to illustrate a limitation on low flow rate operational capability and a related problem of contaminant particle malfunctions. A specific flowmeter used for such illustration is a typical prior art motorless mass flowmeter including a turbine secured to and rotatable with a shaft which in turn rotates a downstream impeller by means of a spring, the impeller being independently supported for rotation, so that relative deflection between the impeller and the shaft is a measure of mass flow rate. To minimize fluid leakage around a peripheral surface of the turbine in proximity to the housing in order to achieve low flow rate operation, while yet avoiding stoppage of the turbine due to contaminant particles being lodged in or near the leakage path, a shroud member is utilized upstream of the turbine which comprises a hollow member of revolution rotatable with the turbine which has a first end secured to the turbine, in a fluid-tight seal, at points radially outward of a plurality of turbine drive means in the turbine and which tapers to a second end, proximate to a fluid inlet opening, to form a rotatable fluid seal with a sealing means surrounding the fluid inlet opening.

International Classification:

G06F 11/00

US Classification:

714 472

Abstract:

An embodiment described herein includes a method for input channel voting. The method includes steps for sorting the three input values by magnitude into a high input value, a middle input value, and a low input value. The three input values are then tested. The testing includes subtracting the middle input value form the high input value to calculate a first difference, and comparing an absolute value of the first difference to a failure threshold. A first intermediate value is determined based on the comparison of the first difference to the failure threshold. The testing also includes subtracting the middle input value from the low input value to calculate a second difference, and comparing the second difference to the failure threshold. A second intermediate value is determined based on this comparison. The first intermediate value and second intermediate value are averaged to produce an output based on the three input values.
