DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
Como solución a los problemas antes mencionados se desarrolló el presente invento el cual comprende de una caja del sistema, que a su vez presenta una abertura por donde el usuario ingresa una o ambas manos, donde una fuente de luz ultravioleta ilumina la(s) mano(s) a ser analizadas y las ondas de luz ultravioleta reflejadas son captadas por una cámara digital que obtiene en tiempo real imágenes y videos de la(s) mano(s) bajo influencia de la luz ultravioleta; dichos datos son enviados a una unidad central de procesamiento portátil para ser analizados y determinar si la(s) mano(s) están bien lavadas; dicha información es enviada a una pantalla digital modular incorporada en la caja que se conecta a la unidad central de procesamiento portátil; donde la pantalla digital permite que el usuario pueda observar, en tiempo real, cómo se ve(n) su(s) mano(s) indicando las zonas en donde aún falta lavar. As a solution to the aforementioned problems, the present invention was developed which comprises a system box, which in turn presents an opening through which the user enters one or both hands, where a source of ultraviolet light illuminates the hand (s) (s) to be analyzed and the reflected ultraviolet light waves are captured by a digital camera that obtains in real time images and videos of the hand (s) under the influence of ultraviolet light; said data is sent to a portable central processing unit to be analyzed and determine if the hand (s) are well washed; said information is sent to a modular digital display incorporated in the box that is connected to the portable central processing unit; where the digital screen allows the user to observe, in real time, how his / her hand (s) looks, indicating the areas where there is still washing to be done.
La unidad central de procesamiento portátil también se encarga de controlar la activación de la fuente de luz ultravioleta mediante una conexión directa. The portable central processing unit is also responsible for controlling the activation of the UV light source through a direct connection.
El sistema se encuentra implementado en una caja de dimensiones variables según el modelo a utilizar para analizar una mano a la vez, o las dos manos juntas. Esta caja atenúa la iluminación externa para que pueda trabajar únicamente con la iluminación de la fuente de luz ultravioleta. The system is implemented in a box of variable dimensions depending on the model to be used to analyze one hand at a time, or both hands together. This box dims the external lighting so that you can work only with the illumination of the UV light source.
La fuente de luz ultravioleta es producida artificialmente para iluminar las manos, o la mano, dentro de la caja. La reflexión de la luz ultravioleta en zonas de las manos no limpias hace que se observen visualmente ciertos patrones característicos. Estos patrones podrían ser reconocidos visualmente por alguien con experiencia en el tema, pero en este sistema son captados por una cámara digital que toma las imágenes y videos, en tiempo real, de la(s) mano(s). The ultraviolet light source is artificially produced to illuminate the hands, or the hand, inside the box. The reflection of ultraviolet light in areas of the unclean hands causes certain characteristic patterns to be visually observed. These patterns could be visually recognized by someone with experience in the field, but in this system they are captured by a digital camera that takes the images and videos, in real time, from the hand (s).
Las imágenes obtenidas son enviadas a una unidad central de procesamiento portátil, la cual extrae los patrones correspondientes para ser analizados mediante un sistema de inteligencia artificial capaz de detectarlos. Por medio de calibraciones según el uso, la unidad central de procesamiento portátil determina si la(s) mano(s) están suficientemente bien lavadas o no por medio de la detección de las regiones de la(s) mano(s) que cumplan con los requisitos para ser consideradas como bien lavadas. The images obtained are sent to a portable central processing unit, which extracts the corresponding patterns to be analyzed by an artificial intelligence system capable of detecting them. Through usage calibrations, the portable central processing unit determines whether or not the hand (s) are sufficiently well washed by detecting the regions of the hand (s) that comply with the requirements to be considered as well washed.
La información correspondiente a las regiones de la(s) mano(s) bien lavadas o no, además de la evaluación de toda la(s) mano(s) es enviada a una pantalla digital modular que se conecta a la unidad central de procesamiento portátil. En esta pantalla el usuario puede observar, en tiempo real, cómo se ve(n) su(s) mano(s) indicando las zonas en donde aún falta lavar, y la evaluación total del sistema. The information corresponding to the regions of the hand (s) well washed or not, in addition to the evaluation of the entire hand (s) is sent to a modular digital display that is connected to the central processing unit portable. On this screen, the user can observe, in real time, how his / her hand (s) looks, indicating the areas where there is still no washing, and the total evaluation of the system.
El procedimiento completo en su modo automático, usando la inteligencia artificial, implica como primer paso que el usuario coloque su(s) mano(s) en el sistema antes de lavarse, y luego al final de lavarse. Esto hace que el sistema de inteligencia artificial adapte su análisis basado en las propias características del usuario reduciendo así errores de intervariabilidad. El análisis de las manos según las características de la persona, como color de piel o posibles lunares, son posibles debido al modelo propio de inteligencia artificial desarrollado e implementado en la invención. The entire procedure in its automatic mode, using artificial intelligence, involves as a first step that the user places his / her hand (s) in the system before washing, and then at the end of washing. This makes the artificial intelligence system adapt its analysis based on the user's own characteristics, thus reducing intervariability errors. The analysis of the hands according to the characteristics of the person, such as skin color or possible moles, are possible due to the own model of artificial intelligence developed and implemented in the invention.
La suciedad o contaminantes que pueden colocarse sobre las manos pueden ser desde polvo, partículas de plástico, grasas, entre otros, que no son detectables a simple vista, puesto que no se ven en el espectro visible. Por ello, la presente invención permite analizar si las manos están bien lavadas o no, detectando mediante la iluminación con la luz ultravioleta rastros de suciedad, y, además, una cámara con una central portátil de procesamiento capaz de detectar las zonas que aún no han sido bien lavadas e indicárselo al usuario. La invención busca ayudar indirectamente a la eliminación de patógenos como virus o bacterias que pueden estar adheridos a la mano mediante la detección y análisis del correcto lavado de manos. The dirt or contaminants that can be placed on the hands can be from dust, plastic particles, grease, among others, which are not detectable with the naked eye, since they are not seen in the visible spectrum. Therefore, the present invention makes it possible to analyze whether the hands are well washed or not, detecting through the illumination with ultraviolet light traces of dirt, and, in addition, a camera with a portable processing unit capable of detecting the areas that have not yet been well washed and indicating it to the user. The invention seeks to indirectly help eliminate pathogens such as viruses or bacteria that may be attached to the hand by detecting and analyzing correct hand washing.
Una ventaja adicional de la presente invención es que todos los componentes están integrados o incorporados en la caja del sistema, lo que facilita su traslado. An additional advantage of the present invention is that all components are integrated or incorporated into the system box, facilitating portability.
