Abstract: A wireless hoist system including a first hoist device having a first motor and a first wireless transceiver and a second hoist device having a second motor and a second wireless transceiver. The wireless hoist system includes a controller in wireless communication with the first wireless transceiver and the second wireless. The controller is configured to receive a user input and determine a first operation parameter and a second operation parameter based on the user input. The controller is also configured to provide, wirelessly, a first control signal indicative of the first operation parameter to the first hoist device and provide, wirelessly, a second control signal indicative of the second operation parameter to the second hoist device. The first hoist device operates based on the first control signal and the second hoist device operates based on the second control signal.

Abstract: Trays and packaging systems for a prosthesis delivery device that permit conversion from a packaged, storage/or shipping configuration to a loading configuration for the loading of a prosthesis. The prosthesis may be a prosthetic heart valve. In the packaged configuration, the delivery device can be supported within the tray, which includes a recess and at least one clip maintaining the delivery device within the recess. In the loading configuration, the delivery device can be arranged for loading of the prosthesis within a bath area of the tray. Optionally, the delivery device can be stored in the packaged configuration in a U-shape. Some embodiments include an additional recess for positioning an indeflator fluid line or tubing. Methods of use are also disclosed.

Abstract: In a nuclear reactor the feedwater control system receives steam generator water level signals, including information to determine signal quality. The signal quality and additional signal validation determine how the water level signals are to be used by the feed-water control system. In the preferred embodiment, each water level signal is compared with a possible range and the difference or differential between all possible pairs of the signals is calculated and compared with an acceptable differential range. While alarms are sounded if any of these checks on the water level signals indicate an invalid signal, the water level signals are used to calculate a median level signal until there is less than two water level signals with good quality within the possible range or all differentials are outside the acceptable differential range.

Abstract: A system for improving the performance of nuclear power plant feedwater control systems and simplifying steam generator low water level reactor protection logic includes a plurality of water level channels for measuring steam generator water level and generating a plurality of signals representative thereof. The median steam generator water level signal is selected from among the plurality of steam generator water level signals. The median steam generator water level signal is then communicated to the feedwater control system through an output interface.
