A plant performance management method includes a step of evaluating performance of a plant based on a relationship between at least two items of data from operating data and a step of analyzing a cause that makes the performance of the plant abnormal based on the operating data in a case in which the performance of the plant is evaluated as abnormal.

A Dielectric Energy Storage System (DESS), a Dielectric Energy Storage System Management System (DESS-MS), and method that stores energy for a wide variety of applications.

Provided is a sensor control apparatus including a main board, a first sensor, a second sensor, and a third sensor, which are connected in series to the main board. The first sensor includes a diagnosis unit configured to perform a failure diagnosis of each of an LED, a phototransistor, and an LED controller. In a case where a failure is detected, the diagnosis unit electrically isolates the first sensor from the series connection, and supplies a power supply voltage to the second sensor.

A system for determining the cause of an abnormality in a semiconductor manufacturing process includes an abnormality mode determination module, a selection module, and a root cause analysis module. The abnormality mode determination module is used to determine the similarity between wafer bin maps containing the abnormal data. When the similarity among the wafer maps is higher than a reference value, the selection module executes the steps of: determining a bad lot based on the wafer maps where the similarity is higher than the reference value; determining a time span within which the bad lot is generated; selecting other bad lots occurring in the time span and satisfying a failure model; selecting a good lot based on a fixed lot interval. The root cause analysis module is used to execute the steps of calculating the correlation among data to obtain confidence indexes.

Methods and systems to control stacked hexapod platforms for use as tools, which function with both high accuracy and high precision are provided. In some embodiments, the methods and systems include a convergence of modern control theory, and machine learning. Furthermore, some embodiments provide control algorithms to carry out autonomous in-space assembly operations using assemblers. Some embodiments provide methods and systems which combine long-reach low precision manipulators and smaller, high-precision assembler with interchangeable tools.

Methods and systems are described for detecting a wide variety of fault conditions in a HVAC system based on analysis of current and historical energy consumption patterns, and on comparison with energy consumption patterns of other similarly situated RTUs. Energy consumption comparisons are preferably made in regard to a normalized load ratio or NLR or more preferably to a daily maximum normalized load ratio or MDNLR, which provide more robust and reliable bases for comparison of faulty and fault-free RTUs, and hence for generalized fault detection, than other previously known metrics or criteria.

A system that allows a contractor to remotely monitor and/or interact with its customers' building control systems, such as heating, ventilating and air conditioning (HVAC) systems, and analyze information obtained from the building control systems over time. Such a system may help the contractor monitor and diagnosis customer building control systems, setup service calls, achieve better customer relations, create more effective marketing opportunities, as well as other functions. In some cases, the disclosed system may be configured to allow a user to grant or deny access to its HVAC system in response to the user receiving an electronic invitation to the system. The granting of access by a user to its HVAC system may allow for remote monitoring of the HVAC system.

The present invention relates to systems and methods for accurately and safely directing the movement of shooting range targets, and more specifically, to provide self-calibration and synchronicity to programmable target carriers and automatically resetting targets.

A controlled dispensing system includes a dispensing fixture and a server system. The server system receives from a first computing device image data corresponding to an identification document and/or face of a consumer, and verifies an identity or age of the consumer based on the image data. The server system obtains a live video feed of the consumer from the first computing device, transmits (i) the live video feed of the consumer and (ii) the image data corresponding to the identification document and/or face of the consumer to a second computing device, receives from the second computing device a verification message indicating that the consumer in the live video feed corresponds to the identification document and/or face of the consumer, and based on the verification message, transmits to the first computing device consumer validation data including an indication that the identity or age of the consumer is verified.

A system that allows a contractor to remotely monitor and/or interact with its customers' building control systems, such as heating, ventilating and air conditioning (HVAC) systems, and analyze information obtained from the building control systems over time. Such a system may help the contractor monitor and diagnosis customer building control systems, setup service calls, achieve better customer relations, create more effective marketing opportunities, as well as other functions. In some cases, the disclosed system may include a controller that analyzes data from HVAC systems, determines a thermal model of a space environmentally controlled by an HVAC system, and provides an energy audit of the space that is environmentally controlled by the HVAC system. The controller may output a result of the energy audit to a user.
