The present invention relates to a drying apparatus capable of regenerating an adsorbent used for drying using microwaves. The drying apparatus of the present invention is formed to include a microwave irradiation means configured to irradiate microwaves to the adsorbent in a plurality of reaction towers in which the adsorbent adsorbing moisture or carbon dioxide is embedded, and when regenerating the adsorbent, directly heats the adsorbent using microwaves, thereby shortening a heating time and securing a sufficient cooling time, resulting in the effect of reducing the amount of dry air consumed for cooling and further increasing the drying efficiency.

Methods and systems are provided for diagnosing degradation and/or alteration in an evaporative emission control system of a vehicle. In one example, a method may include, during a refueling, monitoring a fuel tank pressure and a fuel fill level, and detecting a presence or an absence of a fuel vapor canister of the EVAP system based on a change in fuel tank pressure with an increase in fuel level.

The present disclosure presents infant soothing devices which provide timed, color, and intensity controlled light and sound projections to assist in sleep therapy. The devices may be part of a smart nursery which has a number of electronically connected devices which communicate with a central electronic application to gather information and provide operation instructions to the devices. The smart nursery may be connected to a larger network to provide feedback and controllability outside of the nursery.

An air purification apparatus includes an adsorption unit, a purification passage, and a regeneration passage. The adsorption unit adsorbs carbon dioxide and water vapor in air. The purification passage introduces air in a passenger compartment into the adsorption unit, and returns air, from which the carbon dioxide and the water vapor are adsorbed and removed by the adsorption unit, into the passenger compartment. The regeneration passage introduces air for regeneration into the adsorption unit, and discharges used air for regeneration obtained by regenerating the adsorption unit to an outside of the vehicle. An upstream side of the adsorption unit of the regeneration passage and the purification passage is constituted by an internal air introduction pipeline configured to introduce air from the passenger compartment.
