With an emphasis on highest reliability, infrared (IR) imagers have traditionally used simplest-possible shutters and field-proven technology. Most commonly, single-step rotary or linear magnetic actuators have been used with good success. However, several newer shutter drive technologies offer benefits in size and power reduction, enabling man-portable imagers that are more compact, lighter, and more durable. This paper will discuss improvements in shutter and shutter drive technology, which enable smaller and more power-efficient imagers. Topics will transition from single-step magnetic actuators to multi-stepping magnetic drives, latching vs. balanced systems for blade position shock-resistance, motor and geared motor drives, and associated stepper driver electronics. It will highlight performance tradeoffs pertinent to man-portable military systems. © 2012 SPIE. Source

The two major classes of process pumps such as centrifugal and rotary positive displacement require completely different control techniques. In centrifugal pumps, the control valve response is not directly proportional to the control signal. An increasingly popular control option is to use variable speed drive (VSD) systems with centrifugal pumps. Increasing or decreasing speed allows a broader range of control by shifting the performance curve and best efficiency points (BEP). The rotary pumps cannot be controlled by changing system head because they can develop infinite pressure until something in the system releases it, normally a pressure relief valve that is integral to the pump. Controllability suggests that centrifugal pumps are suited to simple batch processes and tank transfer applications with limited variability than to continuous processes, where two liquid streams must be blended in constant proportions within restrictive control limits.

Pump assemblies are disclosed that have a magnetically driven pump-head subassembly and a pump-driver subassembly coupled thereto, wherein the pump-driver subassembly includes a pump-driver enclosure. The pump-head subassembly comprises a rotatable magnet contained in a magnet cup extending into the pump-driver enclosure. The pump-driver subassembly has a printed circuit board (PCB) in the pump-driver enclosure and a stator mounted to the PCB. The stator coaxially surrounds the magnet cup. The magnet cup has a distal-end wall. The printed circuit board includes a stator-driving circuit and at least one signal-processing circuit. The PCB defines a void relative to the distal-end wall that exposes at least half the distal-end wall. The pump-driver enclosure has an aspect ratio of no greater than one (unity).
