Abstract: A monitoring system is configured to monitor an environment within an enclosure of a heating, ventilation, air conditioning, and/or refrigeration (HVAC&R) system. The monitoring system includes a sensor configured to acquire data indicative of an environmental parameter value within the enclosure. The monitoring system also includes a controller configured to receive the data from the sensor, to determine occurrence of a thermal event within the enclosure based on the data, and to instruct a circuit breaker of the HVAC&R system to transition to a fault configuration in response to determining the occurrence of the thermal event.

Abstract: A radio toy having a plastic toy structure with a body portion erectly fixed on the top of a hollow base and a head portion with a movable lower jaw disposed on the top of the body portion, includes a radio set installed in the hollow base and a magnetic device provided in the mouth of the toy structure in connection with the radio set; thereby, opening and closing of the toy mouth will be automatically effected along with the amplitude of the audio frequency produced by the radio set so as to increase the amusing actions of the radio toy and to stimulate the intelligence of the player.
