Abstract: Devices and techniques are generally described for anomalous network activity detection. In various examples, first application log data comprising a plurality of computer log actions may be received. A hidden Markov model associated may generate a first hidden state vector, where a first value of the first hidden state vector is associated with anomalous activity. A first timing vector associated with a first account may be determined, wherein the timing vector indicates first time periods of typical activity and second periods of typical inactivity for the first account. A first number of elements of the first hidden state vector that have the first value and which correspond to the second time periods of the first timing vector may be determined. Network access may be disabled for the first account.

Abstract: This disclosure describes techniques to evaluate power usage and characteristics on a power distribution system. The power distribution system may include local distribution systems as well as transmission systems. Additionally, this disclosure describes techniques to evaluate the power load on a power system, for example, by using two variable characteristics to model a power load as a sum of a constant impedance load and a constant power load.

Abstract: A monitor for a light circuit comprising a power source, a light being monitored, and a sense resistor. A first voltage amplifier circuit connected to the light circuit has a first output signal representing the voltage across the sense resistor. A second voltage amplifier circuit connected to the circuit has a second output signal representing the voltage across the sense resistor. A microprocessor is configured to receive the output signals from the first and second voltage measuring circuit and is programmed to calculate the current to the light based on the first and second digital output signals, compare the calculated current against a threshold current, and initiate a failure signal if the calculated current is less than the threshold current. A visual indicator activates if the microprocessor initiates a failure signal, whereby the activated indicator notifies that the light is not operating correctly.
