A hair pulling apparatus includes a frame having a longitudinal axis, a first leg extending from the frame, a movable leg spaced apart from the first leg, the movable leg extending from the frame and movable, linearly, relative to the frame, a control system comprising a processor to execute a plurality of pulling profile instructions stored in memory, a linear actuator operatively coupled to the control system and constructed to move linearly along the longitudinal axis relative to the frame, a gripper coupled to the linear actuator, and a load cell coupled to the linear actuator. When one or more of the plurality of pulling profile instructions stored in memory are executed by the processor, the control system causes the linear actuator to retract along the longitudinal axis, applying a pulling force to a strand of hair gripped by the gripper in order to measure the pulling force.

Systems and methods are provided for analyzing conditions associated with a physical feature using digital images. The method comprises acquiring a white-light image and an ultraviolet (UV) image of at least a portion of a body surface, such as a person's face, each of the white-light and UV images including a plurality of pixels and each pixel in the UV image corresponding to a respective pixel in the white-light image. The method further comprises identifying feature pixels in the white-light and UV images, and obtaining results associated with at least one physical condition using information in the feature pixels in the first white light and UV images.

Device logic in a mobile device configures a processor to capture a series of images, such as a video, using a consumer-grade camera, and to analyze the images to determine the best-focused image, of the series of images, that captures a region of interest. The images may be of a textured surface, such as facial skin of a mobile device user. The processor sets a focal length of the camera to a fixed position for collecting the images. The processor may guide the user to position the mobile device for capturing the images, using audible cues. For each image, the processor crops the image to the region of interest, extracts luminance information, and determines one or more energy levels of the luminance via a Laplacian pyramid. The energy levels may be filtered, and then are compared to energy levels of the other images to determine the best-focused image.

A skin analyzer includes a base, an optical imaging system, a flash module, a circuit module, a computing module and a display module. The optical imaging system is disposed on the base for capturing an image of an imaging area. The flash module is disposed on at least one side of the optical imaging system. The circuit module is disposed in the base and electrically connected with the optical imaging system and the flash module. The computing module has a signal transmitting connection with the circuit module. The display module has a signal transmitting connection with the computing module.

The invention relates to providing a method for more conveniently evaluating stratum corneum condition. A stratum corneum sheet is contacted with a solution of a water-soluble dye, and the staining intensity or fluorescence intensity is measured to allow convenient evaluation of the stratum corneum condition. There is further provided a method for evaluating the ameliorating effect of a cosmetic or cosmetic treatment on the stratum corneum, by implementing the method for evaluating stratum corneum condition using a water-soluble dye according to the invention.

Provided are an elasticity evaluation apparatus, an elasticity evaluation method, and a non-transitory computer readable recording medium storing an elasticity evaluation program capable of easily evaluating elasticity of the skin with high accuracy. A skin index calculation part calculates existing amount of gloss portions of a skin in a captured image and existing amount of wrinkle portions of the skin in the captured image as skin evaluation indexes, and an elasticity evaluation part evaluates elasticity of a facial skin of a test subject on the basis of the skin evaluation indexes calculated by the skin index calculation part.

The present invention relates to a process without a therapeutic target that evaluates at least one facial clinical sign and/or evaluates make-up, in particular evaluates wrinkles or fine lines from a portion of the face, including steps consisting in: from a sequence of facial images of a person filmed while emitting at least one sound, extract from the sequence one or more images coinciding with the emission of at least one predefined sound, from the resulting image or images extracted, evaluate at least one facial clinical sign appearing on the image or images extracted and/or evaluate at least one characteristic related to make-up.

An applicator head is releasably connectable to an outer housing of an apparatus for treating human skin includes a body having a housing connector end having a releasable connecting feature configured to connect to the outer housing and a skin engaging end having an opening therethrough for delivering a skin treatment composition through an opening in the applicator head onto human skin. A pair of skin engagement members is arranged and configured to flatten a surface of the skin.

A system and method are presented for use in monitoring one or more conditions of a subject's body. The system includes a control unit which includes an input port for receiving image data, a memory utility, and a processor utility. The image data is indicative of data measured by a pixel detector array and is in the form of a sequence of speckle patterns generated by a portion of the subject's body in response to illumination thereof by coherent light according to a certain sampling time pattern. The memory utility stores one or more predetermined models, the model comprising data indicative of a relation between one or more measurable parameters and one or more conditions of the subject's body. The processor utility is configured and operable for processing the image data to determine one or more corresponding body conditions; and generating output data indicative of the corresponding body conditions.

An apparatus for treating human skin includes an outer housing including a graspable portion and an applicator portion comprising an applicator head and at least one nozzle in the applicator portion having a main axis for delivering a skin treatment composition through an opening in the applicator head onto human skin. An image capture device captures images of the human skin through the opening. A processor analyzes the images of the human skin to identify skin deviations. An optical axis of the image capture device is offset angularly from the main axis of the at least one nozzle.
