TL;DR: A novel mutual inductance based sensor developed and termed MIDOT that has already been used to provide initial results when fielded on high current facilities and can also be used to identify accurately the currents flowing in the independent filaments under transient conditions.
Abstract: Summary form only given. The work described has arisen as part of an on-going joint research programme between AWE and Loughborough University into the dynamics of electromagnetically accelerated flyer plates. A determination of the current distribution (or at least confirmation of the uniformity of the distribution) in a flat transmission line is needed in order to confirm the uniform acceleration of the flyer plate. To this end a novel mutual inductance based sensor has been developed and termed MIDOT. The sensor is calibrated using a stripline comprising an array of independent parallel filaments across the width of the transmission line with a known current flowing through each. This enabled the positional sensitivity of the sensor to be established. A subsequent series of detailed experiments confirmed that the MIDOT sensor can be used to identify accurately the currents flowing in the independent filaments under transient conditions. In contrast to previous work published on the flyer plate program, this paper is dedicated to the development of the bespoke sensor used to determine the current distribution across the flyer plate. The experimental development and results have not previously been published in great detail. The sensor has been developed to a stage where its proof of principle has been convincingly demonstrated on a low voltage test bed and it has been used to provide initial results when fielded on the high current AMPERE and QUATTRO facilities at AWE and Loughborough University respectively.

TL;DR: In this paper, an inductive coil fluid level sensor is used to measure the temperature of the fuel, or fuel vapors, in a fuel tank depending upon the location of the sensor within the tank.
Abstract: This invention provides a method and apparatus for utilizing an inductive coil fluid level sensor to measure the temperature of the fuel, or fuel vapors, in a fuel tank depending upon the location of the sensor within the tank. The inductive coil sensor is connected to a Fuel Control Unit containing the sensor electronics to drive the inductive coil sensor and read the corresponding fuel or fuel vapor temperature.

TL;DR: In this paper, a model of the sensor coil and core was established based on Biot-Savart Law, and a corresponding model was constructed by finite element software, by analyzing the situation of the changing parameters of the coils and core or the installation and processing errors.
Abstract: Aim at the design of inductive displacement sensor,structural characteristic of coil and core is the key factor affecting the sensor performance. In order to improve the detection performance of the sensor,a model of the sensor coil and core was established based on Biot-Savart Law,corresponding model was constructed by finite element software. And then,by analyzing the situation of the changing parameters of the coil and core or the installation and processing errors,the relationship information between measurement performance with varying parameters and installation and processing errors was obtained. The relationship can be used to optimize the sensor. The results indicate that when the ratio of the coil length and the length of the core between 1.45 to 1.6,sensor can get a better relative change of inductance. Linearity is insensitive to the varying of the coil length and core length and radius. It is around at 0.5%, installation eccentric and inclined of the core has little effect on the sensor performance. Relative change of inductance will decrease with increasing of the core taper.

TL;DR: In this paper, a method, system, and computer program product are disclosed for determining a material type of storage media substrates. The method includes using a first sensor to detect an object that indicates the presence of at least one storage media substrate, and using an inductive sensor to determine whether the at least 1 substrate is of a metallic type.
