    摘要： A patch pump utilizes piezoelectricity to dispense medicament from a cartridge syringe to a patient. Pump can include a plurality of piezoelectric elements that when energized cause linear motion of a pushrod that interfaces with the syringe in the cartridge to advance the syringe and dispense the medicament. The high torque generated by the piezoelectric elements is directly converted into the same amount of torque on the lead screw, so no torque increasing gear reduction system is needed and the pushrod utilized to drive the syringe can be contained within and connected directly to the motor assembly. Such a piezoelectric-based system can therefore be made smaller and with fewer moving parts than an electromagnetic motor of the same capability such that the pump has a smaller size than has heretofore been possible with prior art electromagnetic-based syringe pumps and other pumps that utilize gear reduction systems.

    摘要： A patch system and methods for using a patch system are described herein. The patch system has an elastomeric central portion configured to expand and contract over the types of distances commonly found in homes and other buildings that can result in opening and closing cracks in walls, for example. By applying the patch system across a crack under pre-tensioned conditions, opening and closing of the crack will not cause a visible defect in the wall or other surface.

    摘要： An expansion toolhead configured to enable the expansion of multiple different sized diameters of cross-linked polyethylene (PEX) tubing with a single expansion toolhead. The expansion toolhead including a cap operably coupled to an expansion tool, and a plurality of jaws forming a 360 degree jaw section operably coupled to the cap, each of the plurality of jaws including an expansion tool interface portion forming a conical recess enabling a cone-shaped wedge of the expansion tool to move the jaw section between an unexpanded position and an expanded position, and a PEX tubing interface portion having a distal end, a proximal end and a plurality of lands positioned therebetween configured to form a corresponding plurality of substantially uniform diameter portions of the jaw section sequentially increasing in diameter between the distal end and the proximal end for the expansion of multiple different standard sized diameters of VEX tubing.
