Abstract: This paper deals with the system of roughness measurement, especially with the problem of data filtering and processing the results. Theoretical part describes shortly terms roughness, waviness and shape as surface integrity parameters. During phase of measuring we obtain all these three constituents in common. The most important task of post processing is separation of them. That is possible due to roughness HW and SW filters. Other parts of this paper contain SW data filtering description and philosophy of HW filtering. Last part of this article describes SW filters with basic mathematical apparatus, areas of usage and limitations.

Abstract: This template This paper presents a system that provides the most reliable GPS tracking solution for electric powered transportation systems to move people around the sustainable city which can promise of an unmatched quality for giving most accurate location with up-to-date information such as Location, vehicle status, fuel consumption, temperature monitoring, seatbelt status and control to manage your assets. For the system we proposed to use GPS module (u-blox all-in-one GPS receiver for high sensitivity (-162 dBm), fastest connectivity). The hardware shall have a built-in 3-axis accelerometer for motion detection and power saving. Software is modern, sophisticated, full featured, multi-user and error-free software. It is designed for PDAs and smart-phones; hence no downloading of apps or programs is necessary.

Abstract: The magneto-rheological (MR) vibration reduction control technology is studied and a design and implementation of an automobile MR vibration reduction control system based on ARM9 is given in this paper. This paper introduces the system design process of embedded controller, current driver and other hardware, system software structure. Design of real time control system can realize the multi-channel vibration signal acquisition, control algorithm, CAN communications and other functions.

Abstract: In this paper, a new design strategy for the hardware implementation of hearing aid algorithms is proposed. Two familiar hearing aid algorithms—Wide Dynamic Range Compression (WDRC) and Automatic Gain Control (AGC)—are implemented in one circuit as an example. By putting the common arithmetic procedures into common module, the operation units can be used repeatedly. In this way, the area and power consumption are visibly reduced.

Abstract: This paper aims to design and develop a control system for the biped robot. The Peripheral Interface Controller (PIC) main controller board is designed to control the servo motor controller board which assures the biped robot to maintain its stability. This robot consists of PIC microcontroller, servo controller, servo motor, and sensors. The bracket parts are fabricated to mount the servo motors by constructing the biped structure. The PIC microcontroller provides interface among the sensors input, servo motor controller, and servo motor. The biped robot is able to walk in a stable motion under a flat plane. The sensors feedbacks enable the controller to adjust the stability of biped robot. The biped robot is able to perform walking steps and crouching action through the configuration of trajectory angle values of the servo motors.
