Abstract: A smart nozzle system for a hair dryer includes a proximity detection circuit, a temperature sensing circuit, a speed detection circuit, and a rotating nozzle vane, among other features. The nozzle includes a microcontroller and a wireless communication module to interface with an external computing device via an application. Also included is a camera and timer functionality. The nozzle can be an add-on to existing hair dryers or can be integral with a hair dryer system.
Abstract: A power adapter has a main body, a first bus connector, and a second bus connector. The bus connectors are coupled to each other by an integrated circuit. The power adapter draws current from a first power source, such as a smartphone, to a second power source, such as an electronic cigarette. The power adapter snaps into a keyring receptacle for easy use and transportation. The receptacle has a hinged retention member for retaining spare electronic smoking device cartridges or other items.
