Among other things, it allows the user to determine the protection index of the sunscreen he should use depending on the type of skin.
- Figure 1 illustrates a first embodiment shown in perspective view for which the indicating device is in the form of a sliding strip whose use can be repeated;
- Figure 2 is a view similar to Figure 1, illustrating an alternative embodiment
- FIG. 3 shows a second embodiment shown in perspective view for which the indicator device consists of disposable elements after use
- FIG. 4 also illustrates in perspective view, an indicator device produced in the form of a ring
- FIG. 5 shows a fourth embodiment for which the indicating device consists of a box housing electronic means for capturing and displaying the values of the measurements;
- Figure 6 illustrates a fifth embodiment
- FIGS 1 to 6 illustrate individual portable devices, while the embodiment of Figure 7 shows in perspective an alternative embodiment according to which the device is collective.
- FIGS 8 and 9 illustrate two alternative applications of the device according to the invention.
- FIGS. 10 to 11 diagrammatically illustrate the electronic circuits of the devices of FIGS. 8 and 9.
- the indicating device bearing the general reference (1) illustrated in FIG. 1 comprises a strip (2) which constitutes the main support of said device.
- This strip (2) slides in a sheath (3) whose role is to ensure the function of hiding and protecting the capture means (MC) constituted by sensitive sensor elements (4), arranged along the strip.
- MC capture means
- These sensor elements (4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, 4i) are constituted by a succession of rectangular sensitive surfaces each advantageously assigned a number (5a, 5b, 5c, 5d, 5e, 5f, 5g, 5h, 50 corresponding to a given intensity of ultraviolet rays.
- the strip (2) is stored in its sheath (3) ready to be used for another measurement.
- the strip (2) is movable in sliding between a retracted position of non-use in which the sensors (4) are protected, and a projecting position in which the sensors (4) can receive the sun's rays, and this strip includes a gripping member (20) projecting from the sheath (3) in the retracted position of non-use.
- the constituent materials of the sensor elements (4) can be solid or liquid in nature. It may for example be a paint consisting of a solution sensitive to ultraviolet to different degrees. They can be formed by a plate of glass or plastic material, or by a layer of gelatin sensitive to the radiation of the sun and whose coloring varies according to the intensity of the ultraviolet rays.
- the capture elements (4a, 4b, 4c, 4d, 4e, 4f, 4g, 4h, 4i) are different from each other and have, in this respect, characteristics, or at least different sensitivities to ultraviolet rays.
- the more intense the ultraviolet radiation the more sensors will be influenced and their state will have changed, for example to be darker or of a different color.
- the first three sensors (4a, 4b, 4c) will be colored (figure la), while for more intense radiation, the number of colored sensors will be higher, and by example for radiation (R6) more intense than radiation (R3), the first six sensors (4a, 4b, 4c, 4d, 4e, 4f) will be colored, as shown in Figure lb. Therefore, the greater the intensity of the ultraviolet radiation, the greater the number of activated sensors.
- the user in a particularly simple and reliable manner, will be able to determine the intensity of the ultraviolet radiation and in deduce the appropriate degree of protection he should use, and therefore with what type of protective cream he should cover the exposed parts of his body.
- FIG. 2 illustrates a variant according to which, for each sensor (4a, 4b, 4c, 4d, 4th, 4f, 4g, 4h, 4i) corresponds a determined reference pellet, respectively (6a, 6b, 6c, 6d, 6e, 6f, 6g, 6h, 6i).
- Each of the reference pellets having a coloration corresponding to a determined intensity of ultraviolet radiation.
- each colored patch (6) assigned its number corresponds to a determined degree of intensity of ultraviolet radiation which strikes the indicating device (1) in a precise place where the measurement is carried out.
- the sensor element (4) reaches the coloration corresponding to that of a specific patch (6), the color matching then makes it possible to affirm that the ultraviolet rays present require a degree of protection equivalent to the number of said patch. question.
- the support of the indicating device (1) is produced by a block of detachable sheets (7) on each of which are arranged a succession of sensor elements (4).
- Each of these sensor elements (4) is assigned a number (5) corresponding to a given degree of protection against ultraviolet radiation.
- the figures (5) which surmount the sensor elements (4) are each printed in a given color, so that the block of sheets (7) being removed from its protective cover (not shown), one of the sheets (7 ) is exposed to the rays of the sun and these cause the coloring of each of the sensor elements (4) until one of them reaches the color corresponding to a given number (5). Therefore, the degree of protection is indicated and the user takes the appropriate protection measures. After use, the first sheet is detached from the block and the next sheet is ready for a new measurement.
- the indicating device is made from a kind of bracelet (9).
- This bracelet (9) in the form of a cylindrical ring constitutes the support on which are arranged the sensor elements (4) extending over a part of the outer surface (90) of said support.
- the sensor elements (4) are embedded in the thickness of the support, so as to provide a groove on each of their edges (10a, 10b). These grooves are themselves intended to receive a sliding shutter (11) which can then be pulled over the pre-sensitized area of the sensor elements (4).
- the device comprises inter alia means for determining the degree of protection required. Parallel to the sensor elements, graduations (50a, 50b) are arranged representing the different degrees of protection which may be required against solar radiation.
- Each of these graduations (50a, 50b) corresponds to a given coloration which can be reached at the level of the sensor element (4) subjected to a determined ray intensity when the slide flap (11) is removed from the pre- sensitized. As soon as the measurement is carried out, replacing the flap (11) over the sensor elements (4), in a direction transverse to the generatrices of the cylindrical surface (9), means that the sensor element (4) is no longer activated by the sun's rays and the coloring disappears.
- the upper graduation (50a) corresponds to the protection necessary for sensitive skin, while the lower graduation (50b) corresponds to the protection necessary for normal skin.
- the indicating device consists of a housing (12) in which various means are arranged making it possible to capture the ultraviolet rays and to measure their intensity as well as d 'display the measurement result.
- This device can also make it possible to indicate the degree of protection against the sun's rays, by appropriate means.
- a solar sensor (14) is incorporated into the housing (12) and transmits its data on the solar radiation to a microprocessor which calculates the degree of intensity of the solar rays, to translate it into a defined value of degree of protection .
- These values are then displayed by a display system (15) thanks to a current circuit connecting the display member (150 to the calculation unit (microprocessor), and finally to the sensor element.
- the main display (15a) indicates the value of the intensity of the ultraviolet rays
- the displays (15b) and (15c) respectively indicate the degrees of protection on the one hand for skin sensitive (15b) and on the other hand, for normal skin (15c).
- a sliding shutter (13) then obscures the face of the housing comprising the solar collector, and the display system in the non-use position.
- the device further includes a reset button (16a) and a display clear button (16b).
- FIG. 6 illustrates another embodiment of the device in the form of a support constituted by a rectangular plastic card (20), substantially identical to that of credit or telephone cards.
- This card naturally includes a succession of sensors (4) and an upper graduation (50a) corresponding to the protection necessary for sensitive skin, and a lower graduation (50b) corresponding to the protection necessary for normal skin.
- the device also includes another sensor (40) whose coloration indicates that a great risk exists for the skin. This is the case where the place where the measurement is made, is subjected to an excess of ultraviolet rays due to a weakness in the ozone layer. This zone will only be positive when the degree of ultraviolet rays reaching the surface of the earth, at this precise location, is higher than the normal level that human beings can assimilate and endure without danger for him.
- the sensors are for example replaced by a system whose effects are identical to the preceding systems, but by indicating in a constant manner, the progression of the ultraviolet on the place where the measurement is carried out.
- the system is made up of a plastic screen pre-sensitized beforehand and treated according to a precise scale indicating the values of force of ultraviolet.
- the indications may vary depending on the intensity of the ultraviolet rays striking the surface of the earth at the precise place where the measurement is made.
- the screen can have all the forms necessary for the application that one wishes to make of it.
- the nature of the materials used for the manufacture of the screen can also be variable depending on the applications: glass, plastic, cellulose, plexiglass, etc.
- the indicating device whether it comes from a system with coloration sensor elements or with sensor elements of the solar collector type with photovoltaic cell for example, can be adapted to any support other than those described above.
- the field of application of these indicating devices is multiple: traffic signs on beaches, airports, sports grounds, and as a general rule, all public places where the interest, even the need to display radiation solar could be felt.
- FIG. 7 illustrates an example where the support (200) of the collectors is a display panel which comprises two vertical posts (120a, 120b) and whose upper beam (120c) comprises a solar collector (14).
- Other fields of application can also be envisaged in the context of private and personalized objects, such as cases or bottles for sunscreen, watches, bracelets, etc.
- FIGS 8 and 9 thus illustrate two alternative applications of the device of the invention.
- FIG. 9 illustrates another embodiment, according to which the device is in the form of an object intended to be suspended, either on the user's neck or on an object such as a bag or the like.
- the device comprises a dial (34) of generally circular shape, mounted on an elongated support (28) comprising at its upper part a hooking hole (29).
- the dial includes a measurement sensor element (29), a photovoltaic supply sensor (30) and two secondary displays (32,33).
- the device comprises an adjustment button (31) allowing the user to adjust the device as a function of the sensitivity of his skin and thus allowing the display of the degree of protection which is necessary for him therefore as a function of said sensitivity and the intensity of ultraviolet rays, measured by the sensor (29).
- the dial includes a first display (32) allowing the user and thanks to the adjustment button (31) to display the sensitivity of his skin there, the device then automatically displaying on the second display (33) the degree corresponding protection.
