Abstract: A filtering unit includes a housing having outer walls that define a volume and an inner wall that separates the volume into a first chamber and a second chamber. The filtering unit also includes a rigid/flexible circuit board. The circuit board includes a first rigid portion designed to be positioned in the first chamber. The circuit board further includes a second rigid portion designed to be positioned in the second chamber. The circuit board further includes a flexible portion connecting the first rigid portion to the second rigid portion and designed to extend around the inner wall from the first chamber to the second chamber. The filtering unit further includes a bumper designed to be positioned between one of the outer walls and the inner wall to provide waveguide functionality by reducing an amount of electric field that can pass from the first chamber to the second chamber.

Abstract: A high volume carpule system for storing and dispensing a high volume of anesthetic to a patient. A preferred embodiment of the high volume carpule system generally includes a syringe having a modified carpule cavity comprised of an upper ring member and a lower ring member which are linked together by a first side member and a second side member. The side members are oriented in such a manner as to allow a pair of slots through which side portions of a high capacity carpule may extend. A high capacity carpule comprised of a substantially cylindrical shape with an elongated cross-section is disclosed for use with the modified carpule cavity. In an alternate embodiment, a second high capacity carpule design is disclosed for use with conventional, prior art syringes. By using the present invention, a dentist or surgeon may administer a higher volume of anesthetic without having to switch carpules within a syringe.

Abstract: Electronic circuit boards are arranged as respective parallel pairs defining a narrow gap there between. One or more such pairs of boards are supported within a hermitically sealable housing and cooled by way of spraying an atomized liquid coolant from a plurality of nozzles into each narrow gap. Transfer of heat from the circuit boards results in vaporization of at least some of the atomized liquid within the narrow gap. The housing further serves to guide a circulation of vapors out of each narrow gap, back toward the nozzles, and back into each narrow gap. A heat exchanger exhausts heat from the housing and overall system, wherein vapor is condensed back to liquid phase during contact and heat transfer therewith. Condensed liquid is collected and re-pressurized for delivery back to the nozzles such that a sustained cooling operation is performed.

Abstract: A globally cooled computer system for providing liquid cooling to a plurality of electrical components. The globally cooled computer system includes an electronics unit having a plurality of electronics components attached to a plurality of cards and a card cage for providing structural support to the cards, a fluid management unit for pressurizing fluid within the electronics unit, a reservoir for collecting fluid from the electronics unit, a tubing system for distributing the fluid between the electronics unit and the fluid management unit, and a pressure equalization system connecting the electronics unit and the reservoir to equalize internal pressures between them.

Abstract: An insulated spray cooling system for extreme environments for providing a desired enclosed environment for electronic devices regardless of external environmental conditions. The insulated spray cooling system for extreme environments includes an insulated enclosure that isolates the electronic devices being thermally managed from the external environment and a thermal management unit within the enclosure for thermally managing electronic devices.

Abstract: An azeotrope spray cooling system for utilizing an azeotrope coolant for improving the performance of a spray cooling system. An azeotrope coolant is utilized within a two-phase thermal management system for thermally managing one or more heat producing devices. The characteristics of the azeotrope coolant may be adjusted for various types of thermal management applications by altering the components of the azeotrope coolant.

Abstract: A fluid recovery system is adapted for use with a cooling system, such as for use in electronic applications. In one example, an enclosure is configured to contain fluid in both gas and liquid states, wherein the fluid is adapted for use in spray cooling electronic components. A plurality of pick-up ports is defined within the enclosure. In one implementation of the cooling system, an orifice size used in each of the pick-up ports results in withdrawal of fluid from submerged and non-submerged pick-up ports.
