Electronic door lock cylinders need some sort of mechanical actuator to toggle the locking state between open and closed. The main requirements are high security standards, low power consumption, reasonable production costs, and facile integration of the a ...
Hall-effect devices make up by far the largest part of all magnetic sensors on the market today. The main reason is compatibility of Hall devices with modern semiconductor technology. In particular, integrated Hall sensor micro-systems fabricated in low-co ...
The advent of single-photon detectors known as Single-Photon Avalanche Diodes in standard CMOS technology opened the way to new perspectives in integrating these ultra sensitive light sensors with digital logic. Light has some interesting properties that a ...
We present a multisensor designed for industrial compressed air diagnostics and combining the measurement of pressure, flow, and temperature, integrated with the corresponding signal conditioning electronics in a single low-temperature co-fired ceramic (LT ...
In recent years, there has been a large increase in the number of small satellites being designed, built and launched. Due to resource constraints, these spacecraft have not generally included any propulsion capability, and this has severely limited missio ...
Industrial applications often require two or more variable-speed electric drives, which have to be controlled independently. Over the past decade research efforts have been made to reduce the number of power electronic devices required in multi-motor drive ...
Just about every other technical publication you pick up these days makes sweeping statements concerning the pressures on scientists, engineers, and industries as a whole to get to market in less time, with an improved, less expensive product. I am reminde ...
We have designed and realized a new integrated Hall structure that converts the magnetic field vector in the chip plane, into an ac signal, whose amplitude and phase correspond to the magnitude and direction of the field, respectively. It is the first Hall ...
Multi-Processor Systems-on-Chip (MPSoCs) are penetrating the electronics market as a powerful, yet commercially viable, solution to answer the strong and steadily growing demand for scalable and high performance systems, at limited design complexity. Howev ...
This dissertation considers mechatronic systems driven by piezoelectric ultrasonic motors (PUM). The focus is set on optimal system design and sensorless position control. Mechatronic industry faces the challenge to deliver ever more efficient and reliable ...
