An energy storage device having a variable momentum of inertia uses centrifugal forces acting on movable masses to self adjust its moment of inertia. The adjustment of the moment of inertia occurs without any additional energy input. Energy is stored as rotational kinetic energy and potential elastic and/or gravitational energy.

Energy storage device

A completely self-contained replaceable cartridge for micro jet dispensing assemblies is thinner than the spacing between a standard &ldquo;DIP&rdquo; socket. Each cartridge body contains a preferably embedded digitally operated micro jet piezoelectric ejector, a tubular capillary reservoir and fixed connecting pins spaced to removably plug into a standard dual in line packaging (DIP) socket strip or board to receive digital ejection signals. A plurality of the individual replaceable cartridges can be closely positioned together in &ldquo;banks&rdquo; which plug into standard DIP sockets. One or more &ldquo;banks&rdquo; can be plugged into sockets on a housing containing a chamber into which the micro-droplets are deposited. An air movement device may be included with the housing to disperse volatile material that has been ejected into the chamber. The chamber preferably contains a heatable surface onto which the volatile fluids are ejected from the orifices and whereby instantaneous volatilization of the fluid will take place. In an alternate embodiment, each self-contained replaceable cartridge has its own individual heatable surface in the form of a heater mounted adjacent the ejection orifice and one or more additional connecting pins to provide power to operate the heater. A multiplicity of different volatile fluids may be dispensed from a compact assembly in response to command signals from a controller connected to the dispensing assembly.

Cartridge element for micro jet dispensing

A more reliable and precise method of determining the olfactory threshold is provided by a digitally operated apparatus that dispenses controlled amounts of a volatile test fluid from a digital jetting device of the type used for ink jet printing. A precise number and size of micro droplets are dispensed onto a heater which vaporizes the fluid at a test location where a patient can sniff and report whether the odor is sensed. Incremental adjustments are made to determine the approximate threshold of olfactory perception of the odor. Sensors are included to verify dispensing and to coordinate dispensing with breathing.
