Abstract: The present invention is directed to a water pump that may be easily constructed from inexpensive parts and materials and that is powered by the water source from which the water to be pumped is drawn. In a preferred embodiment, two pairs of lever arms located on opposite sides of the pump are alternately filled with water from the source and then emptied causing the lever arms to alternately ascend and descend. As the lever arms ascend and descend, they alternately fill and then compress a pair of pistons causing water to be pumped to an outlet of the pump. Water from the emptied lever arms may preferably be returned to the source, thus minimizing any impact of the pump on the environment and downstream users of the water source.

Abstract: Apparatus is described for administering a substance to a subject. A vial contains the substance and a stopper is disposed within the vial and is slidably coupled to the vial. A first threaded element is (a) rotatable with respect to the vial and (b) substantially immobile proximally with respect to the vial during rotation of the first threaded element. A second threaded element is threadedly coupled to the first threaded element. At least a distal end of the second threaded element is substantially non-rotatable with respect to the vial, and the distal end of the second threaded element defines a coupling portion that couples the second threaded element to the stopper. The first threaded element, by rotating, linearly advances the stopper and at least the distal end of the second threaded element toward a distal end of the vial. Other embodiments are also described.

Abstract: A system may regulate voltage supplied from a power source to an integrated circuit and/or an inertial device. A minimal voltage may be maintained in the integrated circuit by temporarily cutting off current to the inertial device to supply surges of voltage to the controller. Optionally voltage may be smoothed between said surges for example by adding capacitance and/or a current restrictor.

Abstract: An apparatus (110) includes an activation mechanism (20) and a safety latch (122). The activation mechanism is operative to deploy a needle (116) to protrude out of a housing (112), the needle (116) having a longitudinal axis. The safety latch (122) is movably mounted on the housing (112) and formed with a needle opening (129) to allow the needle (116) to pass therethrough. The safety latch (122) has a first position wherein the needle (116) is aligned to pass through the needle opening (129) and a second position wherein the safety latch (122) is moved with respect to the housing (112) such that the needle (116) is blocked from movement in a direction parallel to the longitudinal axis thereof by a portion of the safety latch (122) distanced from the needle opening (129).

Abstract: Inline liquid drug medical device having a longitudinal device axis, a housing with a linear displaceable sliding flow control member displaceable along a transverse bore from a first flow control position for establishing flow communication between a first pair of ports for liquid drug reconstitution purposes to a second flow control position for establishing flow communication between a second pair of ports for liquid drug administration purposes, and a manually operated actuating mechanism for applying a linear displacement force for urging the flow control member to slide along the bore from its first flow control position to its second flow control position.
