Abstract: Systems and method for controlling the flow of a fluidic medium are disclosed. One embodiment of such a system comprises a plurality of first valves logically arranged in an array, the first valves having a control port capable of enabling and disabling fluid flow through a first and second port. The system further includes a row control device connected in parallel to the control port of each first valve in a row of the first valves, and a second valve connected in parallel to one of the first port and second ports of each first valve in a column of the first valves. At least one of the plurality of first valves, row control device, and second valve provide one of a plurality of fluid flows of a fluidic medium through the first and second ports of each first valve in the array.

Abstract: Sensors and methods for measuring displacement are disclosed. In one embodiment, among others, a resistive element is configured to receive an alternating voltage between a first electrical terminal and a second electrical terminal, the first and second electrical terminals defining a length of the resistive element. A signal pickup is capacitively coupled to the resistive element and is configured to be moved along the length of the resistive element at a substantially fixed distance from the resistive element and without contact between the resistive element and the signal pickup. A shielded cable, such as a coaxial cable, electrically connected to the signal pickup carries a signal having an amplitude proportional to the position of the signal pickup with respect to the first and second electrical terminals.
