  • Publication number: 20220253079
    Abstract: Thermal control devices and methods to provide improved control, speed and efficiency in temperature cycling are provided herein. Such thermal control device and methods can include one or more active elements, such a thermoelectric cooler device, that is controlled by an algorithm that regulates a temperature distribution of an adjacent reaction-vessel according to a temperature distribution command trajectory and estimated reaction-vessel temperature distribution. Some embodiments include two active elements that are bilaterally applied to opposing sides of the reaction-vessel. In some embodiments, the estimated reaction-vessel temperature is determined based on a state of power electronics of the element and a temperature output of one or more sensors of a portion of the element and/or an ambient environment of the reaction-vessel. Methods of calibration of such systems utilizing a thermal calibrator as a proxy for the reaction-vessel are also provided herein.

  • Patent number: 8061737
    Abstract: A guard system for a coupling that connects a first component to a second component in a pressurized machinery system includes a coupling guard moveable between an open position, which allows access to an internal region of the coupling, and a closed position, which forms a seal surrounding the coupling from the first component to the second component. The system also includes a guide for directing movement of the coupling guard.

  • Publication number: 20070076736
    Abstract: A low-cost, high-speed data switching system and method uses several parallel switching systems or fabrics. In one of various embodiments, for example, the constituent data flows in a data stream can be selectively routed to a switching fabric that has the lowest input data rate. Data flows can be assigned to the various switching fabrics so as to balance the amount of data passing through each parallel system. Data flows can be re-assigned on an as-needed basis to insure maximum throughput. In the case where a data flow initially routed into one switching fabric must be re-routed to a different fabric, the ordering of data packets can be preserved by withholding the transfer of packets through the second fabric until the packets previously sent into the first fabric have cleared. Methods and apparatus of the present invention find application to parallel computing as well.
