Abstract: A pump for pumping fluid includes a tube platen, a plunger, a bias member, inlet and outlet valves, an actuator mechanism, a position sensor, and a processor. The plunger is configured for actuation toward and away from the infusion-tube when the tube platen is disposed opposite to the plunger. The tube platen can hold an intravenous infusion tube. The bias member is configured to urge the plunger toward the tube platen.

Abstract: A material handler system including a plurality of components and material handler equipment, and methods for utilizing the same, is disclosed. A first component includes gesture command recognition and enhancement for controlling material handler equipment. A second component includes a safeguarding engine for testing the gesture command inputs and improving reliability of the gesture command recognition. A location tracking feature for tracking a location of the material handler equipment in view of a geo-fence is also referenced by the material handler system.

Abstract: A precision modulating globe valve for controlling the flow of a fluid from zero to a maximum flow rate. The valve plug of the globe valve includes at least one flow modulating channel recessed from the outer surface of the valve plug. The outer surface of the valve plug engages a sealing member positioned along the inner surface of the valve port. The sealing member provides a fluid-tight seal between the outer surface of the valve plug and the valve port. The flow modulating channel is recessed from the outer surface of the valve plug from a minimum flow end to a maximum flow end. The radially recessed area of the flow modulating channel increases from the minimum flow end to the maximum flow end, such that as the valve plug moves past the stationary sealing member, an increased flow rate is created through the valve port.

Abstract: A microbolometer detector element (10) for a focal plane array is provided including an optically absorptive material structure (12) characterized by an electrical resistivity that varies as a function of its temperature coupled in spaced relation to a thermal isolation structure (20). The thermal isolation structure (20) is coupled in spaced relation to a sensor (34) connected to the optically absorptive material structure (12) for sensing the absorptive structure's (12) electrical resistivity. The thermal isolation structure (20) facilitates very high fill factors even when the pixel size is shrunk below the baseline fifty micron size. The thickness of the optically absorptive material structure (12) and the thermal isolation structure (20) can be independently controlled since the thermal isolation structure (20) is disposed in spaced relation under the absorptive material structure (12).

Abstract: A pyroelectric focal plane array useful for thermal imaging applications comprises a detector (10), comprises a reticulated and aluminized pyroelectric chip (12) interfaced with a signal processor chip (14) by thermally insulating bumps (30) coated with a thin conductive layer (38) to form a plurality of thermally insulative and electronically conductive interconnections (16) between detector chips (12) and processor chip (14).
