In this paper, an enhanced velocity and acceleration estimation method is presented based on the discrete-time adaptive windowing technique that exclusively employs incremental optical position sensor readings. In a previous work proposed by [1], a first-order adaptive windowing method (FOAW) was shown to be optimal in the sense that it minimizes the velocity error variance while maximizing the accuracy of the estimates. Since the method lacks the ability of accurate acceleration estimation, a new model is developed to estimate the acceleration from signals generated by quantized position sensors. Hence, a numerical solution of an enhanced adaptive windowing (EAW) method is derived and simulated for velocity and acceleration estimation. Effectiveness of the proposed method is validated by experiments done on a one degree of freedom haptic device.

A Transformation Media Based Approach for Efficient Monte Carlo Analysis of Scattering From Rough Surfaces With Objects
Ozgun, Ozlem; Kuzuoğlu, Mustafa (2013-03-01)
This paper presents a computational model that utilizes transformation-based metamaterials to enhance the performance of numerical modeling methods for achieving the statistical characterization of two-dimensional electromagnetic scattering from objects on or above one-dimensional rough sea surfaces. Monte Carlo simulation of the rough surface scattering problem by means of differential equation-based finite methods (such as finite element or finite difference methods) usually places a heavy burden on compu...
An improved data acquisition system for contactless conductivity imaging
Çolak, İlyas Evrim; Gençer, Nevzat Güneri; Department of Electrical and Electronics Engineering (2005)
The previous data acquisiton system developed for the electrical impedance imaging via contactless measurements is improved to obtain measurements with a faster scanning speed of 0.15 sec/mm2. This system uses magnetic excitation to induce currents inside the body and measures the magnetic fields of the induced currents with an axial gradiometer. Gradiometer consists of two differentially connected 10000-turn coils with diameter of 30 mm and a transmitter coil of 100-turn coil of diameter 30 mm placed and m...
A laterally resonating gravimetric sensor with uniform mass sensitivity and high linearity
Eroglu, D.; Bayraktar, E.; Külah, Haluk (2011-09-01)
In this paper, a laterally resonating gravimetric sensor with high linearity and uniform mass sensitivity is presented for biochemical sensor applications including rare-cell detection. The sensor utilizes symmetrically placed, balanced, folded spring beam structures to ensure lateral motion of the proof mass and limit the displacement difference between the proof mass center and edges. The dynamic mass sensitivity range of the resonator is increased by using the above mentioned properties of the resonators...
A current mirroring integration based readout circuit for high performance infrared FPA applications
Külah, Haluk; Akın, Tayfun (2003-04-01)
This paper reports a current mirroring integration (CMI) CMOS readout circuit for high-resolution infrared focal plane array (FPA) applications. The circuit uses a feedback structure with current mirrors to provide stable bias voltage across the photodetector diode, while mirroring the diode current to an integration capacitor. The integration capacitor can be placed outside of the unit pixel, reducing the pixel area and allowing to integrate the current on larger capacitance for larger charge storage capac...
A Capacitive MEMS Accelerometer Readout with Concurrent Detection and Feedback Using Discrete Components
Terzioglu, Yunus; Alper, Said Emre; Azgın, Kıvanç; Akın, Tayfun (2014-05-08)
This paper presents an analog readout method for capacitive MEMS accelerometers in which the feedback actuation and capacitive detection are achieved simultaneously on the same electrode set. The presented circuit operates in closed-loop for improved linearity, and it is constructed in a hybrid platform package in which off-the-shelf discrete components are used together with the silicon-on-glass micro-accelerometer. The system is developed as a practical solution to reduce the complexity of the readout cir...
