Abstract: The present invention discloses a method for monitoring energy efficiency performance of a device, which comprises: connecting the monitored device, obtaining input energy and output energy of the monitored device in a period of time, and calculating an energy efficiency index of the monitored device; and obtaining an energy efficiency deviation based on a standard energy efficiency index of the monitored device, and determining a state of the monitored device based on the energy efficiency deviation. The present invention further discloses a apparatus for monitoring energy efficiency performance of a device. Using the method and apparatus described above, the fine assessment for the device performance can be implemented in a simple way.

Abstract: An apparatus for automated inspection and repair of a tube sheet. The apparatus has a rotating gripper pod, comprising at least one tube gripper, a sliding body portion containing the gripper pod; a housing portion comprising at least one tube gripper and a tool head coupling. The tool head coupling swapably attaches to a eddy current test probe and at least one kind of tube repair tool. Novel, auto-locking tube grippers are also disclosed. A serial bus connects electronic modules within the apparatus and also connects the apparatus to an external controller.

Abstract: A method of tracking backflow assemblies is provided. The method comprises the steps of receiving backflow assembly data for water customers associated with a water supply system, generating a database based on the backflow assembly data, transmitting test reminder notifications to testers associated with the water customers, receiving test result data from the testers, updating the database based on the test result data, and transmitting the test result data to municipal administrators. The backflow assembly data includes water customer information, backflow assembly information and backflow test history information. The database is stored within a storage device. The testers are notified based at least partially on the backflow assembly data. The updated database is stored within the storage device.

Abstract: A solution for measuring steam quality in a steam turbine is disclosed. A steam quality measurement (SQM) device and an ejector are coupled to a steam turbine through an appropriate piping configuration to draw steam emitted from the turbine through the SQM device for measurement of the steam quality, for example, continuously, during operation of the turbine.

Abstract: The present invention relates to a vehicle brake system, which has a brake reservoir, and utilizes a tire management system that is in communication with the brake reservoir and a vehicle operator. As a result of this configuration, the tire management system communicates brake reservoir pressure signals to the vehicle operator, so that the operator is made aware of any low pressure conditions, in the trailer, before trying to move the trailer.

Abstract: A method for calculating moisture loss in a steam turbine operating under wet steam conditions.

Abstract: An inspection tool for a turbine bucket shroud includes: a clamp device for clamping a dovetail portion of a turbine bucket; a template plate provided with an aperture defined by a edge shaped to conform to a specified shape of the turbine bucket shroud, wherein the template is moveable to a location over the turbine bucket shroud in a direction toward the clamp device, and wherein, at the location, the aperture represents a design specification location for the turbine bucket shroud relative to the dovetail portion of the bucket. A measurement gauge is provided for measuring gaps between edges of the shroud and edges of the template aperture.

Abstract: A system comprises a rotary machine, a sensor and a processor. The rotary machine has a component that operates on a fluid. The sensor senses pressure in the fluid. The processor generates a diagnostic indicative of wear on the component, based on process noise on the pressure.
