Abstract: A system of the present invention is capable of detecting, imaging and measuring both neutrons and gamma rays. In some cases, the system has a plurality of parallel plates each containing a plurality of detectors. The plates comprise non-PSD organic scintillation detectors, scintillation detectors having pulse-shape discrimination (PSD) properties, and inorganic scintillation detectors. In some other cases, the system has a plurality of scintillation rods radially distributed about a central axis, and the scintillation rods comprise non-PSD organic scintillation detectors, scintillation detectors having pulse-shape discrimination (PSD) properties, and inorganic scintillation detectors. A first plate or rod and a second plate or rod are used in connection to detect, image and measure neutrons and/or gamma rays.

Abstract: Apparatus including a plurality of droplet ejection devices, an electric source and a controller. Each droplet ejection device includes a fluid chamber having an ejection nozzle, an electrically actuated displacement device associated with the chamber, and a switch having an input connected to the electric source, an output connected to the electrically actuated displacement device, and a control signal input that is controlled by the controller to control whether the input (and thus the electric source) is connected to the output (and thus the electrically actuated device). The electrically actuated displacement device moves between a displaced position and an undisplaced position to change the volume of the chamber as a capacitance associated with the electrically actuated displacement device changes in charge between an actuated condition and an unactuated condition.
