A system allows people to more easily find products matching their skin tone. A kiosk at a retail store or other location can assist customers in determining what products are right for them and then purchase them from the retailer. The kiosk can include a scanning device is used to scan one or more spots of a person's skin. For example, three different spots can be scanned. The scan determines a skin-tone identifier for the person's skin. This skin-tone identifier is used by a software program (e.g., executing on a tablet computer) to determine and output a listing of products that are appropriate for the person's skin tone.

Systems and methods are disclosed that facilitate providing guidance to a user during performance of a program or routine using a personalized avatar. In an aspect, a system includes a reception component configured to receive biochemical information about a physiological state or condition of a user, including information identifying a presence or a status of one or more biomarkers. The system further includes an analysis component configured to determine or infer one or more characteristics of the physiological state or condition of the user based on the information identifying the presence or the status of the one or more biomarkers, and a visualization component configured to adapt an appearance of an avatar presented to the user based on the one or more characteristics to reflect the one or more characteristics.

The present disclosure relates to a method for determining a user-specific hair treatment with determination and inclusion of the degree of damage of the hair. To this end, the content of cysteic acid is firstly determined with the aid of near-infrared and/or infrared spectra of the keratin fibres of an individual and a degree of damage is derived via a calibration model. Individual treatment advice is output on the basis of the determined degree of damage.

A system allows people to more easily find products matching their skin tone. The system includes a database that categorizes cosmetic products according to a skin tone color set. The system includes a scanning device to scan one or more spots of a person's skin. For example, three different spots can be scanned. The scan determines a skin-tone identifier for the person's skin. With this skin-tone identifier, the customer can view products that match their skin tone.

An apparatus for assessing heart failure can include an image sensor configured to capture image data of a patient, a sensor configured to capture sensor data for the patient, a memory configured to store the image data and the sensor data, and a processor coupled to the image sensor, the sensor, and the memory. The processor is configured to receive image data in response to detecting a biological condition from the sensor data, wherein the biological condition is indicative of psychophysiological health and cardiac health. The processor is further configured to detect a visual characteristic from the image data, wherein the visual characteristic is indicative of heart health, and, in response to detecting the visual characteristic, provide an indication that the patient is experiencing a worsening of heart failure.

Method for treating a surface includes: automatically evaluating at least one digital image which includes the target surface; determining the nature of the target surface according to the evaluation of the at least one digital image; determining at least one available treatment implement according to the evaluation of the at least one image; determining the nature of the surface treatment according to the evaluation of the at least one image; automatically determining a use of the determined treatment implement in the determined treatment of the determined surface; and providing information analogous to the determined use of the treatment implement.

Embodiments of the invention include methods and systems for a styling platform. In one embodiment, a method is implemented in a beauty application of a mobile device. The method includes applying a styling feature to a facial image through the beauty application, the method further includes transmitting a message from a first user to a second user through the beauty application, the message containing a hyperlink to the facial image with the styling feature applied. The method further includes establishing a communication session within the beauty application between the first and second users responsive to receiving a reply from the second user, and exchanging information regarding the styling feature within the beauty application between the first and second users using the communication session.

An examination device for optical medical examinations having an optics system and an illumination device. The illumination device includes at least one first light source and at least one second light source arranged in such a way that they illuminate an examination region together. The first light source is configured to emit white light and the second light source is configured to emit light that is bluer than the white light. The light emitted by the at least one second light source has a wavelength in the range of 400 nm to 550 nm and/or the illumination device includes multiple first light sources and multiple second light sources, the first light sources and the second light sources are arranged adjacent to each other and form pairs, wherein the illumination device includes at least one polarization filter that covers every second pair.

A system for sampling a sample material includes a probe which can have an outer probe housing with an open end. A liquid supply conduit within the housing has an outlet positioned to deliver liquid to the open end of the housing. The liquid supply conduit can be connectable to a liquid supply for delivering liquid at a first volumetric flow rate to the open end of the housing. A liquid exhaust conduit within the housing is provided for removing liquid from the open end of the housing. A liquid exhaust system can be provided for removing liquid from the liquid exhaust conduit at a second volumetric flow rate. A droplet dispenser can dispense drops of a sample or a sample-containing solvent into the open end of the housing. A sensor and a processor can be provided to monitor and maintain a liquid dome present at the open end.

A vapor sensor comprises a housing with an inlet opening in fluid communication a sensor element within the housing. Standoff member(s) are positioned to maintain a gap between the inlet opening and a skin site. An operating circuit is in electrical communication with the sensor element and communicatively coupled to and output member. In use, the output member generates a sensory output indicative to an operator regarding concentration of alcoholic vapor in the ambient atmosphere proximate the skin site upon receiving communication from the operating circuit.
