摘要： A multiple port, dual diameter piston fluid dispensing pump which includes multiple input and output ports accessed by rotating at least one of the pistons and a dual or multiple diameter piston or set of pistons that cooperate so that they follow each other. The dispensing piston is of smaller diameter than the pushing piston. This diameter difference permits a longer, controllable stroke to dispense micro-liters of fluid accurately.

摘要： A precision fluid dispensing system that can be effectively used for accurate fluid dispensing in peristaltic pumps if roller control is used. Peristaltic pumps can be combined with pinch valves allowing a dispense tube to be open while a source tube is blocked. Controlled roller movement is used to move the next roller to the same starting position as the previous roller was on the previous dispense, the dispense pinch valve is closed and the source valve is opened. The system uses roller positioning where the each roller is properly positioned so that each dispense cycle starts in the same position. The precision and accuracy is better than 0.3% total.

摘要： A cell sorter system that includes a precision pump that causes fluid containing cells to enter an inlet port where the fluid is exposed to source light of one or more wavelengths and where cells scatter light or produce fluorescence by known means, and the scattered light and/or fluorescence is used to detect the presence and position of desired cells. The fluid is passed into a select gate that can be magnetostrictive where it is cause to exit one of a plurality of ports, at least one of these ports receiving the desired cells. A controller controls the precision pump, the detection system, and the select gate so that cells are selected from the fluid. An optional vacuum system can be used to pull fluid or cells out of the selected exit port.

摘要： A method of making beams, clamps and other structures by curing a polymer containing a magnetostrictive material. A magnetostrictive material like TERFENOL-D™ is placed in a polymer. This mixture is put onto a slide in a film. The mixture is cured by UV light (or other means) so that it cross-links. A second layer of polymer with no magnetostrictive material can be cured on top of the first layer. This leads to a beam structure which exhibits a bending moment in an applied magnetic field. By aligning the magnetostrictive particles before curing with a magnetic field, a beam or other structure can be produced with aligned particles. A mask can be used to selectively cure regions where the magnetostrictive particles have different alignments on the same layer. It is possible to build up multiple layer structures with layers of magnetostrictive particles aligned in different directions.
摘要翻译：通过固化含有磁致伸缩材料的聚合物来制造光束，夹子和其它结构的方法。将诸如TERFENOL-D TM的磁致伸缩材料置于聚合物中。将该混合物放在胶片中的载玻片上。混合物通过紫外线（或其他方式）固化，使其交联。可以在第一层的顶部固化第二层无磁致伸缩材料的聚合物。这导致在所施加的磁场中呈现弯曲力矩的梁结构。通过将固化前的磁致伸缩颗粒与磁场对准，可以用对准的颗粒产生束或其它结构。可以使用掩模来选择性地固化磁致伸缩颗粒在同一层上具有不同对准的区域。可以建立具有沿不同方向排列的磁致伸缩颗粒层的多层结构。

摘要： A method and a kit for oil removal or injection into the oil pan of a vehicle, marine or aircraft engine. A modified dip stick tube extends to the bottom of the oil pan has at least one or more openings at its bottom end to allow oil to enter or exit. The top has an air-tight seal that can be attached to a flexible tube that can be run to a peristaltic pump. The pump can have an exit tube that runs into an oil recovery receptacle. After draining, the oil, the tube can be valved or physically relocated to a fresh oil source. The direction of rotation of the pump can be reversed to fill the oil pan with fresh oil. An electric control can run the pump in both a forward and reverse direction typically from a vehicle battery voltage source.
