Abstract:
A system for verifying applications for Real-Time Execution (RTE) devices is provided. The system includes a memory, at least one processor coupled to the memory, and a simulation component executable by the at least one processor. The simulation component may be configured to receive device simulation information for an RTE device, the device simulation information including device configuration information, application information, and targeted performance information, configure a virtual device simulator to simulate performance of the RTE device, run the virtual device simulator to process one or more simulated events, and output simulation results.
Abstract:
Systems and methods for monitoring an HVAC&R system employ a monitoring agent that uses observations of evaporator and condenser intake temperatures, evaporator discharge temperature, and a compressor input power parameter to learn operating characteristics of the HVAC&R system in newly maintained condition. Thereafter, the agent continuously or regularly computes a relative coefficient of performance (COP) for the system under subsequent observed ambient conditions, and relates the present instantaneous efficiency of the HVAC&R system under the observed ambient conditions to the instantaneous efficiency when the system was in newly maintained condition. The relative COP can be used to detect system degradation and quantify the energy usage and cost attributable to the degradation. The agent can take appropriate actions to prevent/minimize damage based on the degree of degradation detected, including shutting off power to the HVAC&R system. The monitoring agent can also be extended to other types of systems besides HVAC&R system.
Abstract:
An apparatus provides a single split-bus electrical panel with back-feed circuit breakers arranged to allow connection of a Microgrid Interconnection Device (MID) for isolation of a critical loads section from a standards loads section during back-up operation due to a utility power outage. A first panel section of the split-bus electrical panel supplies power to non-critical standards loads in a residence. A second panel section of the split-bus electrical panel supplies power to critical loads in the residence, which must continue to be powered during a utility power outage.
Abstract:
Embodiments described herein provide techniques for managing sensitive data within maintenance reports. A first maintenance report comprising an instance of text data describing a maintenance event for a first physical apparatus is retrieved and is processed using a trained Named Entity Recognition model to identify instances of one or more words that are associated with a respective real-world name(s). Embodiments determine whether a first identified instance of one or more words represents sensitive data, using a data anonymization rules ontology that describes a plurality of different ways to identify sensitive data within maintenance reports. If the first maintenance report is determined to include sensitive data, the first maintenance report is flagged as a potentially sensitive maintenance report that requires further review. If the first maintenance report is determined to not include any sensitive data, the first maintenance report is added to a plurality of maintenance reports to be externally released.
Abstract:
A current transformer includes a first housing including a first handle portion and a first distal portion, a second housing including a second handle portion and a second distal portion, a first core mounted in in the first distal portion, a second core mounted in the second distal portion, and a lock attached to the second handle portion at a pivot point, wherein the first housing is rotationally coupled to the second housing about a fulcrum point and the lock is rotatable about the pivot point into a closed position wherein the lock engages the first handle portion and prevents the first handle portion and the second handle portion from rotating towards each other.
Abstract:
Systems and methods for sensing current provide a planar coil current sensor for a current flow monitoring device in which an electrically conductive trace is formed on a printed circuit board (PCB) substrate in a spiral or winding pattern to form a planar coil. The spiral or winding pattern may take the form of a polygonal, circular, or other shape depending on the particular implementation. Such a planar coil current sensor may then be placed in close proximity to a current carrying conductor to sense the current in the conductor. The current in the conductor induces an electromagnetic field around the conductor that, in turn, generates a voltage in the nearby planar coil current sensor. The inductively coupled voltage in the planar coil current sensor may then be used to monitor and measure the current in the conductor.

A circuit breaker can include a moveable electrical contact configured to be moved between an open position and a closed position, and a lever assembly configured to prevent the progressive closing of the moveable electrical contact to the closed position such that the lever assembly is configured to cause snap action closing of the moveable electrical contact at a charged position of a motorized slider.
Abstract:
A current transformer for a ground fault circuit interrupter (GFCI) can include a core having a closed loop shape having a first side, a second side, and a core opening, and a sense coil wrapped around the core configured to magnetically couple to a plurality of conductors passing through the core opening. The current transformer can include a first magnetic shield disposed on the first side of the core over the sense coil, and a second magnetic shield disposed on a second side of the core over the sense coil.
