  • System and method for cooling using a heat exchanger having a membrane
    Patent number: 10584926
    Abstract: A heat exchanger that includes a membrane of graphene oxide is disclosed, as is a heat exchange system employing such a heat exchanger. The heat exchanger permits the use of water from non-traditional sources, such as waste water, brackish and sea water, in a cooling loop. Clean water and sensible heat permeate through the membrane, simultaneously cooling and purifying water in the cooling loop.

  • Fast packet switch
    Patent number: 5563876
    Abstract: The invention provides a very fast distributed frame relay switch. Each switching element is tied to each other switching element using LAN like FDDI technology. Frame relay packets arrive into the switch via lower speed TDM based trunks and can either be switched locally within the same switching element or can be switched to a remote switching element via the FDDI bus. The switching elements themselves reside in a TDM based multiplexer, thus can utilize existing TDM interfaces.
