Abstract: In one aspect, a system for recharging a refrigeration system of a vehicle is provided. The system includes a refrigerant delivery device configured to removably couple to a recharge port of the refrigeration system. The refrigerant delivery device comprises a controller, a refrigerant container, and at least one sensor. The controller is configured to communicatively couple with User Equipment (UE) of a user over a communication channel. The refrigerant container stores a refrigerant. The at least one sensor is configured to measure one or more parameters of the refrigeration system. The controller is configured to transmit, via the communication channel, the one or more parameters of the refrigeration system to the UE, receive, via the communication channel, one or more commands from the UE to perform a recharge process for the refrigeration system, and selectively deliver the refrigerant to the refrigeration system in response to the one or more commands.

Abstract: An example embodiment of a volatile substance diffuser comprises a housing defining a housing axis; and a component carrying a volatile substance. The component defines an air passageway there through. The component is secured to an inner surface of the housing. The air passageway defines an air passageway axis and the housing axis and the air passageway axis are approximately parallel. In an example embodiment, the volatile substance diffuser further comprises a clip secured to the housing and configured to removably secure the volatile substance diffuser to a slat of an air vent (e.g., an automobile air vent, building air vent, and/or the like).
