A wide-bandwidth and high-sensitivity robust microgyroscope Sahin, Korhan; Sahin, Emre; Alper, Said Emre; Akın, Tayfun (IOP Publishing, 2009-07-01) This paper reports a microgyroscope design concept with the help of a 2 degrees of freedom (DoF) sense mode to achieve a wide bandwidth without sacrificing mechanical and electronic sensitivity and to obtain robust operation against variations under ambient conditions. The design concept is demonstrated with a tuning fork microgyroscope fabricated with an in-house silicon-on-glass micromachining process. When the fabricated gyroscope is operated with a relatively wide bandwidth of 1 kHz, measurements show a...
A robust traffic sign recognition system Becer, Hüseyin Caner; Bulut, Mehmet Mete; Akar, Gözde; Department of Electrical and Electronics Engineering (2011) The traffic sign detection and recognition system is an essential part of the driver warning and assistance systems. In this thesis, traffic sign recognition system is studied. We considered circular, triangular and square Turkish traffic signs. For detection stage, we have two different approaches. In first approach, we assume that the detected signs are available. In the second approach, the region of interest of the traffic sign image is given. Traffic sign is extracted from ROI by using a detection algo...
A low-cost rate-grade nickel microgyroscope Alper, Said Emre; Silay, Kanber Mithat; Akın, Tayfun (Elsevier BV, 2006-11-08) This paper presents a low-cost microgyroscope with a resolution in the rate-grade at atmospheric pressure, which is fabricated using a CMOScompatible nickel electrofonning process. Angular rate resolution of the gyroscope is increased by matching the resonance frequencies of the drive and sense modes close to each other using symmetric suspensions and electrostatic frequency tuning; whereas, undesired mechanical coupling between the two modes during matched mode operation is reduced by the fully decoupled g...
A miniature and non-resonant vibration-based energy harvester structure Zorlu, Ozge; Külah, Haluk (Elsevier BV; 2012-09-12) This paper presents a miniature and non-resonant vibration based electromagnetic (EM) energy harvester, which generates energy from low frequency and low amplitude vibrations. The structure combines a MEMS-based coil realized on a parylene cantilever, and a miniature NdFeB magnet, resulting in a small sized EM harvester prototype with a strong magnetic part. The magnet is attached to a moving platform, whereas the coil is fixed to a stationary base. The mechanical frequency up-conversion (mFupC) technique i...
A Self-Powered and Efficient Rectifier for Electromagnetic Energy Harvesters Ulusan, Hasan; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2014-11-05) This paper presents an interface circuit for efficient rectification of voltages from electromagnetic (EM) energy harvesters operating with very low vibration frequencies. The interface utilizes a dual-rail AC/DC doubler which benefits from the full cycle of the input AC voltage, and minimizes the forward bias voltage drop with an active diode structure. The active diodes are powered through an AC/DC quadrupler with diode connected (passive) transistors. The interface system has been validated to drive 22 m...
