A battery powered blow dryer having a novel heating element technology that can be powered by an attached battery pack. The heating element includes an infrared light bulb that emits high heat with relatively low power consumption compared to current methods. The present invention patent also describes a unique configuration of battery cells to optimally perform the task of blow drying hair.

A dryer and sanitizer unit includes a drying chamber for enclosing one or more portable rechargeable electronic devices. The drying chamber is defined by a base and a repositionable lid that covers the base. The base includes a substantially horizontal surface upon which the electronic devices are disposed. Air vents are disposed around a perimeter of the horizontal surface through which warm air may flow into the drying chamber to contact the electronic devices. The air vents at least partially surround the electronic devices disposed on the base. The unit also includes one or more disinfecting light sources, such as UV-C light sources, disposed within the drying chamber.

A battery powered blow dryer having a novel battery cooling feature to simultaneously cool the batteries and improve hair dryer performance.

A material drying system provides for consistent and efficient drying of organic materials, such as cannabis. In certain embodiments, a partial vacuum drying system is used to dry the materials and includes a container, a heating system, a depressurization system, and a control system. Air in the container is heated to within a range of temperatures and a low vacuum is applied to assist with evaporation. In addition, the volume flow rate of air pulled out of the container is monitored and maintained at a predetermined rate, which pulls moisture away from the materials so as to prevent degradation of the materials during the drying process while also reducing drying time. A relatively high air volume flow rate is maintained at low pressure by adjusting the area of an opening in the chamber.

Hair extension drying device includes an enclosure comprising a base and an upwardly extending wall surrounding the base. The wall is configured for receiving a top cover of the enclosure. A fan is coupled to the top cover with the fan being configured for circulating air within the enclosure. A heating unit is coupled to the base. A hair extension holder spaced apart from the heating unit by one or more vertical supports. The hair extension holder includes at least one laterally extending plate that includes perforations or fluid pathways.

A system for producing dry nanoparticles from a liquid includes a closed tubing system which incorporates a mister, heater and an electrostatic collector therein. The system is able to produce dry nanoparticles from liquid-suspensions and from solvent solutions.

In a method for determining a temperature of a revolving drum of a laundry dryer, said drum has an outer wall and thereon at least one strip-shaped delimited detection region comprising thermochromic material having a transition temperature in the range of a temperature that is to be expected and to be determined. Optical detection means arranged adjacent to the revolving part are configured, in particular as a reflected light barrier, to detect the color transition of the thermochromic material in the event of the transition temperature being exceeded or undershot. At the revolving drum the thermochromic material or, if appropriate, the color transition thereof is detected by means of the detection means. A temperature of the drum is then determined as corresponding to the transition temperature in such a way that the temperature thereof is determined as corresponding to one of the two temperature ranges below the transition temperature or above the transition temperature.
