Abstract: Provided is an apparatus which includes a near-to-eye display, a microcontroller, a hot shoe interface with an external port configured to communicate with an external mounting device for the near-to-eye-display, a hot shoe interface line between the external port and the microcontroller, and a communication line between the external port and the microcontroller. The communication line is configured to share at least a portion of the hot shoe interface line, and is also configured to transmit and receive external communications through the external port. The microcontroller is configured to activate and inactivate transmission over the communication line in response to predetermined signals received over the communication line within a first predetermined time period of at least one of the near-to-eye display being powered-on or the mounting device transitioning from one of an active orientation or a stowed orientation to the other.

Abstract: A test kit for a digital and analog electronic circuit breaker determines the calibration and overcurrent response of the circuit breaker when connected within an electric power circuit. The test kit simulates an overcurrent condition and provides verification of the circuit breaker response without de-energizing the circuit breaker or interfering with the circuit breaker's protection functions. The test kit connects with the digital communications circuit within the digital circuit breaker to obtain status information concerning pick-up conditions, trip conditions and fault currents which are viewed on the test kit liquid crystal display. A ground fault suppression circuit is included within the test kit for single-phase current-injection without causing ground fault tripping. The test kit circuit further includes means for optionally tripping the circuit breaker upon completion of any of the tests.
