Traditionally, the 4 20 mA analog signal used in industry to interface sensors in distributed process control has been replaced with relatively simple digital networks, called "field-buses", and recently by Ethernet.
The system integrates a smart card unit, acting as a user machine interface, sensors, actuators, interfaces, a PLC controller that incorporates the fuzzy control algorithm, local operating network (LON) modules and devices and an optional PC which monitors the performance of the system.
[14], the six major functional groups are Interface Sensors, Perception, Control, Vehicle Interface, and User Interface.
The library components belong to the control objects layer of the open controller architecture and implement functionality for sensor interfacing, sensor modeling, pattern recognition, state estimation and state regulation.

For the sake of easiness we just call the software interfaces sensors too.
Excessive power consumption is holding back the evolution of mobile devices because the improvements at the battery levels are not significant in comparison to the rapidly growing energy demands for wireless interfaces, sensors, applications and features.
The first component is the neural interface, a sensor that reads the firing of neurons in the brain.
The fabrication and testing of a minimally intrusive (2 mm high, 10 mm diameter) biomedical interface pressure sensor are described.
