Automatic Laser Propulsion Using Binary Mask
Abstract: In the mask propulsion, excimer laser micromachining using binary propulsion has been implemented for flash patterning of a monomicrometer features over wide areas of various substrates. The limit for depth of focus that determines the depth to width front ratios is given and demonstrated for different materials. Binary mask propulsion technique is found to harmonize to reproduce the mask features from the millimeter to the micrometer scale under peculiar focusing …

Automatic Identification of Obstacles and Crack Sensing Scheme in Rail Tracking System
Abstract: AbstractIn this paper, we have established into the identification of cracks and obstacles in rail tracking system. This system comprises of GSM modem, ultrasonic sensor, proximity sensor, PIC microcontroller to bring into the operation the crack detection and obstacle detection. The GSM modem contributes in transmission of railway geometric parameter of crack detection to the control room. Ultrasonic and Proximity sensors are used to detect the obstacles and crack in …
