Claim of US Patent No. 10,433,455

1. An in-wall electrical outlet comprising:a housing arranged and configured to be received within a single gang wall box located in a wall or ceiling, the housing including at least one of a line voltage port and a low voltage port for providing power to a removable load, the housing having an intake opening in a first surface thereof for directing cooling air into an internal portion of the housing, the housing having an exhaust opening in a second surface thereof for exhausting heated air from the internal portion of the housing,
a strap to fasten the housing to the single gang wall;
a fan disposed within the housing, the fan operable to draw the cooling air in through the intake opening and to exhaust the heated air through the exhaust opening;
a thermal load disposed within the housing, the thermal load positioned to receive the cooling air to reduce a temperature of the thermal load;
a temperature sensor for determining a sensed temperature of the internal portion of the housing;
a microcontroller logic circuit for energizing the fan based on the sensed temperature of the internal portion of the housing; and
a safety shut off to reduce or disconnect power to the low voltage port if the fan is determined to have failed;
wherein the microcontroller logic circuit energizes the fan when the sensed temperature of the internal portion of the housing is determined to exceed a first predetermined threshold; and
wherein the microcontroller logic circuit determines the fan has failed when the sensed temperature exceeds the first predetermined threshold by a predetermined value and controls the safety shut off to reduce or disconnect power to the low voltage port.
