Abstract: A system and method for detecting subliminal facial responses of a human subject to subliminal stimuli. The method includes: receiving captured first facial response data approximately time-locked with a presentation of subliminal target stimuli to a plurality of human subjects; receiving captured second facial response data approximately time-locked with a presentation of subliminal foil stimuli to the plurality of human subjects; receiving captured unidentified facial response data to a subliminal stimulus from the target human subject; determining a target probability measure that the unidentified facial response data of the target human subject is in response to the subliminal target stimuli using a machine learning model trained with a subliminal response training set, the subliminal response training set comprising the first captured facial response data and the captured second facial response data; and outputting the target probability measure.

Abstract: A circuit for an Intelligent Electrical device (IED) is disclosed. Using this circuit, the IEDs can be used in harsh industrial environments, such as those present in power utility substations. The circuit may comprise a dual stage isolated power supply. The dual stage isolated power supply has a first DC to DC converter for converting received power from the received voltage to an intermediate voltage. The intermediate voltage is then further converted to a voltage which can be used by the Ethernet IED. Each of the DC to DC converters also provide galvanic isolation and also transient suppression and electromagnetic interference filtering to decrease adverse electrical effects which may be inherent in the power received from an external source. The first and second DC to DC converter provides a first level of galvanic isolation which is greater than the second level of galvanic isolation provided by the second DC to DC converter.

Abstract: A device for hardening an Ethernet switch is disclosed. The device provides cooling for the switch, and, suppresses electrical transients and electromagnetic interference, which could affect the power supply, and data transmission of the Ethernet switch. Using this device, the Ethernet switch can be used in harsh industrial environments, such as those present in power utility substations.

Abstract: A protective relay having an embedded web server to allow communication with a remote device having a standard web browser package. The relay can receive and transmit HTML files according to the HTTP protocol over a communications network. The relay can receive commands from the remote device, and can generate and return requested data to the remote device.

Abstract: A system and method for monitoring a utility substation is provided. The system for monitoring a utility substation includes monitoring equipment connected to a utility substation for monitoring operating conditions of the utility substation. The monitoring equipment is connected to an application service provider through a first communication network. One or more network interface devices are connected to the application service provider by a second communication network, which may be the same communication network as the first communication network. The one or more network interface devices receive notification of operating conditions of the utility substation monitored by the monitoring equipment through the application service provider.

Abstract: A protective relay having internal processing circuitry embodied by removable and replaceable modules. Each module includes a main circuit board having common circuitry and also includes removable and replaceable submodules which electrically connect with the main circuit board to perform specific functions. The protective relay can have its functions altered by replacing one or more modules or submodules.

Abstract: A redundant communications scheme for a protective relay which allows high-speed, reliable, and fault tolerant communications between peer protective devices in a power distribution network. Communications over a selectable primary communication channel are interrupted and switched to a secondary communication channel, which can operate according to a different communication protocol, when a fault is detected on the primary communication channel. The fault detection and switching is performed transparently to the main protective relay processor.
