TL;DR: In this paper, an inductive sensing type position detection device is described, which includes a resonator including an LC circuit, a driver for generating a driving signal having a resonant frequency of the LC circuit and an inductively sensed sensor module including a coil pattern part where an oscillation coil which is driven by the driving signal generated by the driver and generates the oscillation signal, a cosine wave receiving coil and a sine wave received coil for receiving a signal induced by electromagnetic induction according to an electric signal induced in the resonator as a Sine wave and a cos
Abstract: Disclosed is an inductive sensing type position detection device. The inductive sensing type position detection device according to an embodiment of the present invention includes: a resonator including an LC circuit; a driver for generating a driving signal having a resonant frequency of the LC circuit; an inductive sensor module including a coil pattern part where an oscillation coil which is driven by the driving signal generated by the driver and generates the oscillation signal, a cosine wave receiving coil and a sine wave receiving coil for receiving a signal induced by electromagnetic induction according to an electric signal induced in the resonator as a sine wave and a cosine wave are stacked in a multi-layered structure; and a position detection module which detects at least one of a rotation position and a straight line position of the resonator by analyzing the sine wave. In the resonator, the electric signal can be induced in correspondence to the oscillation signal by the electromagnetic induction.

TL;DR: This paper investigates the signal to noise performance when use contemporary ultra low noise op-amps in the schematic designs without J-FET buffering.
Abstract: Some medical and industrial applications use inductive source sensors. In many cases these sensors produce low voltages even lower than 0,1mV. On the other hand these sensors have significant inductance (more than 150mH and up to 1H). This paper investigates the signal to noise performance when use contemporary ultra low noise op-amps in the schematic designs without J-FET buffering. There exist very low noise op-amps with voltage noise less than the noise of $50\Omega$ resistor but they are not suitable for inductive sources.

TL;DR: A new system for measuring dental implant mobility was developed using an inductive sensor and an amplification adaptor to multiply movement of the implant and showed linear relationship with the depth and the diameter of the hole.
Abstract: Estimation of dental implant stability is an important factor for diagnosis of implant treatment. In this study, we have developed a new system for measuring dental implant mobility. Movement of the implant was measured by an inductive sensor and an amplification adaptor was developed to multiply movement of the implant. Impulse response signal of the implant was acquired and power spectrum analysis was applied for the signal. Various implant-tissue interfacial conditions were simulated in an in vitro experiment and average peak frequency of the power spectrum was calculated for each condition. Artificial implantation model of acryl was fabricated and holes of different levels of depth and diameter were drilled. Two types of impression materials were used to fix the dental implant into the hole. The peak frequency showed linear relationship (P-value<0.01) with the depth and the diameter of the hole. Differentiability of the system was evaluated by ANOVA test.

TL;DR: In this paper, the authors present an inductive sensor, in particular rpm sensor, having a housing (4) with a main housing body (5) and a coil base body (6), whereby a coil is wound around the base body.
Abstract: In summary, the present invention concerns an inductive sensor, in particular rpm sensor, having a housing (4) with a main housing body (5) and a coil base body (6), whereby a coil is wound around the coil base body (6). The sensor also comprises a magnet (2) that is situated in the housing and has a pole pin (3). The coil base body (6) of the housing (4) is thereby designed entirely conical, in particular slightly conical, in shape.
