  • Patent number: 10823478
    Abstract: A modular cooling/heating device includes a thermal plant such as a micro-refrigeration system with an integrated heater for providing remote, on-site cooling/heating to an insulated enclosure defining a modular cooling volume by exchanging a liquid thermal-transfer medium, such as available tap water or alcohol-glycol mixture, with a thermal exchanger disposed within the insulated enclosure. A thermal source adapted for thermal exchange with a fluidic transfer medium combined with an engageable fluidic coupling between the thermal source and the thermal exchanger provides for detachable engagement of the thermal exchanger in a verity of contexts. The thermal exchange may take the form of a flexible, fluid carrying pouch, or a rigid thermal vessel having substantial vacuum and phase-change lining features for thermal inertia. Both may be combined with an integrated, insulated enclosure including the battery and thermal source as a combined, portable package.

  • Patent number: 10731790
    Abstract: A modular integrated mounting system includes a plurality of mounting struts secured to a floor or deck surface, at least one cross mounting rail movably attached perpendicular to the mounting struts, a foot lock receiver attached to the at least one cross mounting rail, and a foot lock configured to be attached to equipment and to be retained by the foot lock receiver.

  • Patent number: 7548566
    Abstract: The present invention provides quantum cascade lasers and amplifier that operate in a frequency range of about 1 Terahertz to about 10 Terahertz. In one aspect, a quantum cascade laser of the invention includes a semiconductor heterostructure that provides a plurality of lasing modules connected in series. Each lasing module includes a plurality of quantum well structure that collectively generate at least an upper lasing state, a lower lasing state, and a relaxation state such that the upper and the lower lasing states are separated by an energy corresponding to an optical frequency in a range of about 1 to about 10 Terahertz. The lower lasing state is selectively depopulated via resonant LO-phonon scattering of electrons into the relaxation state.
