  • Patent number: 9950198
    Abstract: An apparatus includes a scrubber bed, a cooling unit operatively connected to the scrubber bed, and a frame configured for a user to carry the apparatus. The cooling unit includes a compressor, a condensing coil operatively connecting the compressor to an expansion valve, and an evaporating coil operatively connecting the expansion valve to the compressor, and a first fluid circulating through the compressor, the condensing coil, the expansion valve, and the evaporating coil. A method of cooling a gas in a rebreather apparatus includes scrubbing an exhalation gas to produce a recycled gas having a lower concentration of carbon dioxide than the exhalation gas, compressing, condensing, expanding, and evaporating a refrigerant in a closed-loop system, transferring heat energy from the recycled gas to the refrigerant, and metering a cooled gas to the user.

  • Patent number: 9251697
    Abstract: A refrigerated container system is described that includes a wireless personal area network (WPAN) including a plurality of wireless sensor nodes and a coordinator node through which the sensors provide sensor data to a controller for the refrigerated container system. The wireless sensors and the coordinator incorporate a variety of features that ensure efficient utilization of battery life by preventing unintended pairing of sensors with other WPANs and excessive sensor signal processing arising from door chatter. Finally, pairing is performed without pressing a button on the wireless door sensor. Instead, the sensor's magnetic reed switch is enlisted to detect swiping of a magnet by a user to enter a pairing mode.

  • Patent number: 7479399
    Abstract: A system and method is described for providing automated sample preparation for plan view transmission electron microscopy. A sample wafer is microcleaved from a semiconductor wafer and mounted on a first support stub. Then the sample wafer is cut with an automated diamond sawing tool to expose a cross sectional view of the sample wafer. The sample wafer is removed from the first support stub and rotated to orient the sample wafer for plan view imaging. The rotated sample wafer is then remounted on a second support stub and cut with the automated diamond sawing tool to expose a plan view surface of the rotated sample wafer. The remounted sample wafer is subsequently prepared for focused ion beam (FIB) milling and plan view transmission electron microscopy imaging.
