Safety device (100) per nails (101), said device (100) being characterized in that it comprises a sheet (103) in resistant material, developing principally along a first and a second axis (X, Y), suitable for being installed over of a nail of a person and below of a fake nail (102), said sheet (103) in resistant material comprising in an its first end cutting and/or pointed means (104; 104a, 104b, 104c) susceptible of realizing a receptacle where containing portions of skin of an aggressor.

Embodiment provided herein are directed to microneedle patches for agent application on a mammal skin. The microneedle patch may comprise a patch scaffold having a surface, and a plurality of microneedles disposed on the surface. Each of the microneedles may be capable of piercing the skin 50 m to 1000 m deep, and comprises a composite material comprising polyvinylpyrrolidone (PVP) and one or more additional copolymers selected from the group consisting of maltose, leucine, and dileucine.

Embodiments of the present invention provide fluid applicator systems that allow access to product located at the bottom of the bottle toward the end of the useful lifetime of the product. There is provided a platform that moves with respect to the bottle base and an applicator that moves with respect to the cap.

A system and method for an intelligent hair drying/styling apparatus with user information transmission and storage capabilities is herein provided. The hair drying/styling apparatus houses a control circuit board and an infrared or temperature sensor (or camera) in order detect an individual's hair condition moisture level to determine a user specific, customizable dryer setting. The information detected by the sensor is stored locally, on a proximal Internet-enabled device, or on a remote or cloud-based server and accessed by the hair drying/styling apparatus through a wireless local area network connectivity function. Accordingly, a user's hair temperature-drying profile may be stored and later recalled to provide optimal hair styling setting customized for that user. This innovation will enable any number of hair professionals and or end consumers to improve styling and dry time. Such a profile may contain a proprietary V-Factor calculation that will, among other applications, correspond to the use of a coordinated and optimized hair spray solution. According to the present invention, energy usage is reduced to enable a more efficient design.

A system for releasably connecting a plurality of interchangeable components in an assembly. The system includes a plurality of units and a plurality of interchangeable components capable of being releasably joined to one or more of the plurality of units. The plurality of units further includes a physical connecting system and a magnetic connecting system for relative positioning of at least one of the plurality of units with at least another one of the plurality of units. The physical connecting system includes a set of physical keys. The set of physical keys includes an indentation and projection on the surface of the unit. The magnetic connecting system includes a plurality of magnetic connectors housed in the interior housing of each of the plurality of units.

A handheld personal care device according to the present disclosure includes: an operation switch configured to change a treatment operation of an operation unit; a sensor electrode configured to cause a change in capacitance depending on whether or not the grip unit is grasped; and a control device electrically connected to the operation switch and the sensor electrode and configured to control the treatment operation of the operation unit. The control device includes: a grasp detector configured to detect that the grip unit is grasped based on a change in capacitance of the sensor electrode; and a change permission part configured to permit the operation switch to change the treatment operation of the operation unit when the change permission part receives, from the grasp detector, grasp information indicating that the grip unit is grasped.
