Abstract:
A system configured to monitor ambient illumination experienced by a subject. In one embodiment, the system comprises an illumination sensor, a timer, and a storage module. The illumination sensor is configured to monitor an intensity of ambient illumination within two or more wavelength ranges by generating one or more output signals that convey information related to the intensity of ambient illumination within the two or more wavelength ranges. The timer is configured to indicate the passage of periods of time. The storage module is configured to store information related to the intensity of ambient illumination within the two or more wavelength ranges, as conveyed by the one or more output signals, for individual periods of time. The system is portable to be carried by the subject.

Abstract:
A device (1) for determining a personalized sun exposure program has a portable casing (2) housing a processing unit (4) associated with a memory (5); the processing unit (4) is connected to a data-entry keyboard (9), to sun sensors (12), and to a light source (15) associated with a photometric detector (16) for measuring the light emitted by the light source (15) and reflected by a user's skin surface; the processing unit (4) calculates an intensity value (I), representing local sun conditions, on the basis of the measurement supplied by the sensors (12), and calculates a reflection value (R D ), representing the user's phototype and skin condition, on the basis of the measurement supplied by the detector (16); the processing unit then supplies a personalized sun exposure program as a function of the reflection value (R D ) and the intensity value (I); and the program indicates one or more exposure periods and, for each period, the time of day, the exposure time, and the sun protection factor to be used in that period.
Abstract:
Various embodiments of a light detection device and a method of using such device are disclosed. In one or more embodiments, the light detection device can include a housing including a top surface and a bottom surface, where the housing extends along a housing axis between the top surface and the bottom surface; and a support member connected to the housing and adapted to be selectively moved from a closed position to an open position.
