  • Patent number: 9362736
    Abstract: A solid state switch module is provided for use in a power distribution network including an input differential protection connection for receiving a measured current value from an upstream module. The solid state switch module also includes an output differential protection connection for sending a measured current value. The solid state switch module includes a trip outlet for sending a trip signal to an upstream solid state switch, and a trip inlet for receiving a trip signal from a downstream solid state switch. The trip inlet is operably coupled to the switch. A current sensor measures the current value of a connected power transmission line across the solid state switch module. A summer adds a current input from a parallel module with the current measures by the current sensor. A comparator determines whether an amount of current lost between the solid state switch module and an upstream module is acceptable.

  • Patent number: 9354265
    Abstract: Exemplary systems and methods are directed to establishing a signature for a device emitting electromagnetic radiation (EMR). The system includes a radio frequency (RF) receiver, a signal processor, and a signature generator. The RF receiver samples detected EMR, generate pulses having characteristics that are a function of the EMR, and select generated pulses in a spectral band having energy above a predetermined threshold. The signal processor establishes a set of correlated pulses, computes a vector space associated with the set of correlated pulses, and compares each pulse in the set of correlated pulses to a basis of the vector space for establishing a device signature, and associates pulses having a threshold percentage of energy within the basis in a database with a device identifier.
