A system for treating skin, the system including at least one cartridge containing a skincare material, a dispensing device comprising at least one chamber configured to accept the at least one cartridge, and a processor communicatively coupled to the dispensing device, wherein the processor is configured to visualize an image of a user's skin, detect one or more features on the user's skin with image processing, and apply the skincare product onto the one or more skin conditions to the user's skin through an applicator on the dispensing device.

Apparatuses and methods are disclosed for assessing the texture of skin using images thereof. In exemplary embodiments, a texture map of an area of skin is generated from a combination of a parallel-polarized image and a cross-polarized image of the area of skin. The texture map is then flattened to remove the underlying curvature of the skin. A texture roughness metric is then generated based on the flattened texture map. An image of the texture map and the metric can be displayed to provide visual and alphanumeric representations of the texture of skin, thereby facilitating the comparison of baseline and follow-up images of the skin, such as those taken before and after treatment.

An apparatus for non-invasively measuring bio-information is provided. The apparatus for estimating bio-information may include a pulse wave sensor configured to measure a pulse wave signal from an object; a sensor position sensor configured to obtain sensor position information of the pulse wave sensor with respect to the object, based on the object being in contact with the pulse wave sensor; and a processor configured to estimate the bio-information based on blood vessel position information of the object, the sensor position information, and the pulse wave signal.

A wearable device may include a main body, a sensor formed on a stem disposed on a side of the main body, and configured to acquire a partial fingerprint image of a finger of a user based on the finger being in contact with the sensor, and a processor configured to control a display to guide the user based on the acquired partial fingerprint image and a full fingerprint image of the finger to permit a measurement site of the finger to contact the sensor.

An apparatus for estimating bio-information is provided. The apparatus for estimating bio-information may include a pulse wave sensor configured to measure a pulse wave signal from an object; a force sensor configured to measure a first force exerted between the object and the pulse wave sensor; and a processor configured to: convert the first force into a second force, based on structure information of the object; and estimate the bio-information, based on the pulse wave signal and the second force.

In some aspects, the present disclosure provides methods for identifying a disease in an epithelial tissue of a subject. Methods for identifying a disease in an epithelial tissue comprise the generation of a depth profile of the epithelial tissue using signals generated from the tissue by pulses of light directed towards a surface of the epithelial tissue. In some aspects, the present disclosure provides apparatuses consistent with the methods herein.

An object of the present invention is to provide a technique of quantitatively measuring physical properties including both of viscosity and elasticity. A viscoelasticity measurement system includes a measurement apparatus, a processor, and a display apparatus. The measurement apparatus includes a movable unit continuously pressed against a measurement object, a first sensor outputting acceleration information corresponding to an acceleration of pressing-directional movement of a contact portion of the movable unit with respect to the measurement object, and a second sensor outputting reactive force information corresponding to a reactive force applied to the contact portion of the movable unit with respect to the measurement object. The processor calculates first information on an elasticity component of the measurement object and second information on a viscosity component of the measurement object based on the acceleration information and the reactive force information. The display apparatus displays the first information and the second information.

Tissue surface tracking of tissue features is disclosed. First surface imaged features are tracked based on the first and second time spaced images at a first wavelength. Second surface imaged features are tracked based on the first and second time spaced tissue surface images at the second wavelength. Tracking metrics are obtained based on the tracking steps. The tracking steps are combined to provide a combined tracking metric. The combined tracking metric is used in a tissue surface navigation application.

A method for identifying a dendritic pore is provided. Line and pore images are obtained from a digital image of a subject's skin. These line and pore images are overlaid to identify those pores having at least one line intersecting the pore as dendritic pores.

A neurotransmitter imbalance detection system (SYS) is disclosed, said system (SYS) comprising at least one eye movement sensor (SEN) for sensing movement of a closed eye (EYE), a frequency analysis arrangement (FAA), and wherein said eye movement sensor (SEN) is configured to output at least one eye movement signal (EMS) representing movement of the closed eye (EYE) and to communicate said at least one eye movement signal (EMS) to said frequency analysis arrangement (FAA), wherein said frequency analysis arrangement (FAA) is configured to receive said at least one eye movement signal (EMS) and process said at least one eye movement signal (EMS) by frequency analysis to determine a frequency distribution. Also, methods for identifying eye movement patterns, for detecting a neurotransmitter imbalance, for identifying a psychiatric disorder, and for treating a psychiatric disorder are disclosed.
