TL;DR: In this paper, a Direct Digital Converter suitable for variable reluctance sensors is presented, which has two inductors that vary in a push-pull manner with respect to the measurand.
Abstract: Novel, simple and accurate Direct Digital Converters suitable for variable reluctance sensors are presented in this paper. These sensors have two inductors that vary in a push-pull manner with-respect-to the measurand. It is known that a small linear range can be obtained by taking the difference between the values of the sensor inductances. The proposed digital readout circuits accept the sensor inductances having non-linear characteristics, and provide a linear digital output directly proportional to the measurand, which is linear for the entire sensor range. The converters work on the principle of voltage-to-time based conversion and possess many advantages. Prototypes have been built and tested with a typical differential inductive sensor arrangement with a nominal value of 10mH. Output was linear for the full range of input and the worst-case error was less than 0.2%.

26 Jan 2005TL;DR: In this paper, a method for operating a sensor, particularly a yaw rate sensor, which is housed inside a housing, is described, in order to detect the dangerous influence of mechanical vibrations upon the output measured value of the sensor, the vibrations are sensed at the location of the sensors, and the sensor or an electronic device interacting with the sensor is switched off so long as the vibrations exceed an established intensity.
Abstract: The invention relates to a method for operating a sensor (1), particularly a yaw rate sensor, which is housed inside a housing (10). In order to detect the dangerous influence of mechanical vibrations upon the output measured value of the sensor (1), the vibrations are sensed at the location of the sensor (1), and the sensor (1) or an electronic device (3) interacting with the sensor (1) is switched off so long as the vibrations exceed an established intensity. The method can be used, in particularly, in a driving dynamics control (FDR) of a road vehicle.

TL;DR: The radial inductive sensor with harmonic rejection as mentioned in this paper comprises two pairs of detectors, each extending over approximately 60 DEG of the periphery of the reference ring, and each U-shaped detector piece 202 comprises first and second branches 204, 205, along which the corresponding detector detects the radial displacements of the rotor with respect to the stator.
Abstract: The radial inductive sensor with harmonic rejection comprises two pairs of detectors 221, 222 and 223, 224, each extending over approximately 60 DEG of the periphery of the reference ring 211, and each U-shaped detector piece 202 comprises first and second branches 204, 205, which are symmetrical with respect to the radial reference axis XX' or YY', along which the corresponding detector detects the radial displacements of the rotor with respect to the stator. This sensor rejects even harmonics and the third harmonic.

TL;DR: Wang et al. as mentioned in this paper presented a novel inductive tactile sensor array with rigid stainless-steel bump sensing interface for 3D micro joystick button application, which is implemented using standard TSMC 0.35 μm 2P4M CMOS process and in-house post-CMOS processes.
Abstract: This study presents a novel inductive tactile sensor array with rigid stainless-steel bump sensing interface for 3D micro joystick button application (Fig. 1a-b). The presented micro joystick button design using inductive sensor array and stainless-steel bump interface has several merits: (1) batch process to define and etch bumps on stainless-steel sheet, (2) compact sensing coil array using CMOS platform can distinguish the magnitude and distribution of tactile loads, and (3) polymer as spring and encapsulation layer to cover the rigid tactile bump and CMOS chip without any fragile suspended thin film structure. The design is implemented using standard TSMC 0.35 μm 2P4M CMOS process and in-house post-CMOS processes. Measurements show sensing signals from the proposed sensor array could distinguish the loading conditions for 3D micro joystick button application.
