  • AIRFOIL TO PROVIDE DIRECTED COOLING
    Publication number: 20160037687
    Abstract: An airfoil to provide directed cooling of active elements, such as in a multi-device storage enclosure. In accordance with some embodiments, an apparatus includes a housing having opposing first and second ends. A first active element is mounted within the housing adjacent the first end, and a second active element mounted within the housing adjacent the second end. A fan assembly is mounted within the housing adjacent the second end to establish an airflow through the housing adjacent the first and second active elements for cooling thereof. An airfoil is mounted within the housing between the first and second active elements to accelerate and direct the airflow proximate the second active element.
    Type: Application

  • Peripheral gauge
    Patent number: 5767413
    Abstract: A gauge for measuring a dimensional change, such as a change in the periphery of a test object, is an elastomeric tube filled with an electrically conductive fluid such as mercury. The gauge can be formed into a loop around the test object. Thereafter, any change in, e.g. the circumference of the test object is monitored by measuring the change in resistance (or voltage) between the ends of the tube.
