Abstract: An apparatus and method for sensing a rotational parameter of a rotating member of a downhole pumping system. The apparatus is capable of detecting motor rotation and pump operating conditions and includes control systems for methods utilizing the rotational parameters to control the operation of the downhole pumping system.

Abstract: This application relates to a building energy analysis and management system for measurement and verification of building performance. The system can analyze, optimize, manage, maintain, trouble shoot, and/or modify building systems, such as HVAC systems, in connection with the building energy usage. Measurements may be gathered for one or more HVAC units coupled to pressure independent valves, and sent to one or more Surge Panels that pass data to remote analysis servers, which can receive other system or external data. The analysis servers compare measurements to predicted values and can standardize the predicted values to account for external conditions. The comparison can result in difference values used to generate probable causes and optimization recommendations. The system outputs reports or other data display using a graphical user interface that can be adjusted for an anticipated user.

Abstract: A mechanism eliminates the number of times a user must login to individual services after initially logging into a computer system. A user only logs once into a computer system, and subsequent login requests by multiple services are handled automatically and transparently by the system. In one implementation, a user need only present a card to a card reader and enter a PIN, and the user is logged-in after presenting the card and a valid PIN. The system generates a token that is valid for this particular login session of the user, and when the user accesses a permissioned service, the system automatically logs-in the user to the application using the token. The system can perform the automatic login the user to a variety of applications including legacy applications, web-enabled applications, and commercial, off-the-shelf applications.
