A relay and metering test instrument includes an application processor circuitry to control functional operation of the relay and metering test instrument. The application processor circuitry may receive a user selected source code state program, and operational parameters input by the user. The application processor circuitry may compile the source code state program and the operational parameters into a test routine for storage in a memory circuitry with other test routines. The relay and metering instrument may also include a real time processor circuitry and an input/output processor circuitry. The real time processor circuitry may selectively and independently execute the test routine or one of the other test routines to perform one or more respective testing stages. The input/output processor circuitry may cooperatively operate with the real time processor circuitry to output test signals and monitor for receipt of input test signals according to execution of the test routine.

Configurable test instrument for power equipment

An emergency vehicle alert system includes a traffic control device having a transceiver. The transceiver is configured to receive a first signal and to transmit a second signal. A receiver is configured to receive the second signal from the transceiver and to initiate an alert upon receiving the second signal from the transceiver. The first signal is transmitted to the transceiver from an emergency vehicle and causes the traffic control device to transition from a first configuration to a second configuration. The transceiver transmits the second signal in response to the transceiver receiving the first signal.

Emergency vehicle alert system

A diagnostic test instrument for testing power system equipment may include a chassis having a number of bays capable of receiving test circuitry modules, which may be field inserted by a user desiring to perform a particular test. The instrument may include controller circuitry that may sense in each of the bays whether a respective test circuitry module is inserted therein, and then interrogate respective test circuitry modules in each respective bay to identify a type of the respective test circuitry module. Available testing capabilities may be identified according to the type of each of the respective test circuitry modules identified in respective bays. The controller circuitry may output configuration instructions to test circuitry modules, and respective test ports included in each of the respective test circuitry modules may be selectively illuminated as a configuration instruction to visually identify an assigned functionality of the respective test ports.
