An exemplary embodiment of the invention is a nozzle, for use in an injection device, that projects material at an ultra-high velocity. The nozzle includes an integrally formed body having an interior passageway that has a longitudinal axis. The input of the nozzle is configured to interface with a cartridge, and the output is configured to be placed proximate to a target. The passageway includes a taper, and its path length, from an initial diameter to a position along the passageway where the passageway first reaches a smallest diameter, is at least 0.5 mm. The taper of the passageway defines a shape, in a plane that includes the longitudinal axis, that is a continuous and monotonically decreasing function of distance along the longitudinal axis in a direction of flow through the nozzle.

Disclosed is an apparatus for a rocker. In one embodiment, the rocker may be comprised of a fixed support structure; a resonant pendulum suspended from the fixed support structure, a seat or bed suspended on the pendulum; and a coil coupled to the pendulum and interacting with a magnetic field to supply force to the pendulum to maintain movement of the seat or bed. The rocker may also be comprised of a rechargeable battery that is used to power the coil and allow for the rocker to run continuously. The battery may be charged by the coil's interactions with the magnetic field or using at least one solar panel. The solar panel may also be used without a battery to provide energy to the rocker so that it may run continuously. The coil may be comprised of an electrically conducting wire (e.g., copper or aluminum wire).
