We present a view-based method for steering a robot in a network of positions; this includes navigation along a prerecorded path, but also allows for arbitrary movement of the robot between adjacent positions in the network. The approach uses an upward-looking omnidirectional camera; even a very modest quality of the optical system is sufficient, since

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2017
The type and magnitude of loads that pass through the track superstructure have a great impact on both the design and the performance of the concrete crossties and fastening systems. To date, the majority of North American research that focus on quantifying the rail infrastructure loading conditions has been conducted on heavy-haul freight railroads ...

A 30 V rail-to-rail operational amplifier
Microelectronics Journal, 2015This work presents a high-voltage (HV) operational amplifier (OPA). OPAs are widely used in signal conditioning circuits for industrial applications and integrated circuits (ICs). Particularly, in HV applications like BMS (battery management system), the signal conditioning circuits are always used to transfer voltage signal between HV domain and low ...

A rail-to-rail ping-pong op-amp
IEEE Journal of Solid-State Circuits, 1996A rail-to-rail ping-pong op-amp achieves offset cancellation and 1/f noise reduction without folding of the input spectrum. The clocking scheme minimizes the clock feedthrough and the residual offset due to charge injection. With a clock frequency of 100 kHz, the residual offset is less than 100 /spl mu/V, and the input referred noise is about 225 nV ...

A RAIL-TO-RAIL BUFFER AMPLIFIER FOR LCD DRIVER
Journal of Circuits, Systems and Computers, 2011A high-speed low-power rail-to-rail buffer amplifier, which is suitable for liquid crystal display driver applications, is proposed. An offset voltage is intentionally built in the second stage to cut off the transistors of last stage from the output node in the stable state and hence achieve low dc power consumption. The input referred offset voltage
