    摘要: In a hair styling device (20) having a two-dimensional array (21) of elements to bring hair at a styling temperature, the elements produce optical radiation energy. The elements may include one or more LEDs, and preferably a plurality of LEDs, in which case the LEDS are driven in clusters that may be of mutually different shapes and sizes. The hair styling device (20) further comprises sensors to obtain an areal light absorption measurement opposed to the two-dimensional array of elements, and a control unit for individually controlling the elements in dependence of the measurement. The sensors may be arranged for measuring an areal light density profile of a whole treatment area. The hair styling device may radiate hair from two sides, both of which includes an areal light absorption measurement. The sensors may include LEDs that do not produce light.

    摘要: Nail gel curing devices emitting ultraviolet light, as well as methods of their making and use are disclosed. The devices are useful for curing, inter alia, acrylic compositions, more particularly, acrylic nail gel compositions, and typically employ ultraviolet and/or visible light emitting diodes (“LED”) to cure such ultraviolet and/or visible light curable nail gel resins.

    摘要: Devices, systems, and methods are provided for applying a cosmetic design to a biological subject. An applicator array device may include a substrate. The applicator array device may include a plurality of applicator elements disposed on the substrate, together defining an applicator array. Each applicator element may include a first electrode, an electroactive polymer layer disposed on the first electrode, and a second electrode, disposed on the electroactive polymer layer. The applicator array device may also include an applicator surface overlying the applicator array. Each applicator element may be configured to switch between a first position and a second position upon application of a voltage to the first electrode or the second electrode, or upon removal of the voltage from the first electrode or the second electrode.

    摘要: The present disclosure relates to the technical field of hairdressing, in particular to, a novel far infrared hair dryer, including: a body, which is provided with a fluid inlet formed in a rear end and a fluid outlet formed in a front end; a fluid flowing path, which is arranged in the body and extends from the fluid inlet to the fluid outlet; a conveying mechanism, which is arranged in the fluid flowing path and drives a fluid to flow from the fluid inlet to the fluid outlet; and a heating mechanism, which is arranged in the fluid flowing path and is used for heating the fluid in the fluid flowing path. The novel far infrared hair dryer can improve the compactness of the overall structure to the maximum extent, ensure that air is blown out smoothly, and reduce the obstruction to the air, thus reducing noise.
