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 method, system, and computer program product is provided that controls platen movement during a live scan. The platen moves in response to finger movement. The present invention then applies a counter force that counters the platen movement. In one embodiment, the counter force has a magnitude which is a function of the speed of the platen movement. The platen can move in a lateral direction (right or left) in response to the finger. The direction in which the counter force is applied is a direction that counters the platen movement in a determined direction. In one example, the force is applied through a motor that drives the platen in a direction opposite the direction of movement caused by the finger or fingers during the live scan. In this way, the counter force which is applied helps prevent a user from moving a finger too rapidly during the live scan. As a result, a high-quality fingerprint image can be obtained with less training and experience in live scan fingerprinting.
