ELECTRONIC DEVICE ANGLE INCREMENT DEVICE

DESCRIPTION

OBJECT OF THE INVENTION

Electronic device for increasing the angle of vision that mounted on a glass or integrated into it allows to expand the visual field of people who suffer from a visual disability, by projecting color video images in front of the user's active visual area.

It can also be used in people without disabilities who, for any type of need, need to expand or vary their field of vision in the horizontal or vertical plane.

FIELD OF THE INVENTION

As an area of the invention, the optics industry and the manufacturer of electronic devices are considered

BACKGROUND OF THE INVENTION

Let's look at some previous definitions to be able to limit the real field of the invention.

The total area in which objects can be seen in lateral (peripheral) vision is defined as the visual field, while the person focuses the eyes on a central point.

The visual field varies from one person to another. Each eye sees approximately 150 ° on a horizontal plane, increasing to 180 ° with the superposition of both eyes. In vertical plane it reaches about 130 °, 60 ° above the horizontal and 70 ° below.

The loss of visual field may be due to diseases of the central nervous system, such as tumors that can injure or press on visual organs. or other diseases such as:

Diabetes, Glaucoma, Retinitis pigmentosa, Hypertension, Sclerosis

Multiple, Optical Glioma, Very Active Thyroid (Hyperthyroidism), Pituitary Disorders, Retinal Detachment, Stroke, and Temporary Arteritis.

In addition to all of them, the first cause of low vision in the developed world that can lead to blindness is age-related macular degeneration (DEMAE)

The recovery of vision in those patients who have completely lost vision or are in a state of low vision is in various investigations as a dream to achieve.

Professor Eberhart Zrenner of the University of Tubingen in Germany has tested a prosthesis called `` Retina '' implanted in the patient's retina, which is equipped with hundreds of micro-diodes that receive light from an outer chamber and excite the optic nerve that transmit the image to the brain reproducing there.

Most recent is the ‘’ Argus ’’ system of the US Second Sight company. It uses a different system but also requires operation and implant inside the eye. This system is carried out in Spain at the Barraquer Clinic and only patients whose vision loss is total is applicable.

As we can see, there are several prototype glasses to transmit information to the brain through an intermediate processor.

These teams are complex, require delicate operations and are mainly aimed at patients who, due to degenerative changes or other causes, have lost their vision or are close to that state.

On the contrary, the present invention is a portable, lightweight and immediate application device, and is intended for the visually impaired whose reduced visual field is likely to be extended by this device.

It can also be used in people without disabilities who, for any type of need, need to expand or vary their field of vision in the horizontal or vertical plane.

Thanks to the miniaturization of the electronics, a device containing a front camera and a processor that projects the image to the active area of the field of vision of the eyeglass can be inserted into the pin of a spectacle frame. patient through a reflection prism.

Therefore, the present invention has the task of presenting a device that, integrated in a spectacle pin or mounted on the frame of a standard spectacle, allows to increase the visual field of the visually impaired.

The device is basically composed of a camera for capturing video images, a signal processor and a projection device that projects color images through a reflection prism, or two prisms depending on the light source, modulated by the corresponding sensor; so that the user visualizes them in the active part of his field of vision.

To accommodate the reduced field of vision of the patient, the model incorporates a simple pen system and an axis for the two-dimensional translation of the optical imaging system.

In this way the user can place the deflector prism by hand exactly in the most appropriate area of his field of vision.

The device can be mounted on both pins because the image projection is reversible.

The electronic system may optionally have a voice "interface" for word commands: connection / disconnection, high / medium / low brightness level, zoom ...

As an energy supply element, an energy storage battery is provided, incorporated into the device, which is recharged by a mini-USB female connector on the back of the mechanism and is intended for a duration of approximately 60 min. in continuous projection.

As an accessory you can have a battery-shaped battery plug-in to the device using a mini-USB male connector for an approximate duration of 12 hours in continuous projection.

It can also be used in people without disabilities who, for any type of need, need to expand or vary their field of vision in the horizontal or vertical plane.

The electronic device for vision enhancement that the invention advocates is understood to be mounted on the pin of a spectacle or directly on a spectacle mount (2), with an upper lens hood (3) to avoid direct light on the area and in a way The invention is preferably constituted by at least the following elements that make up the device.

.- External housing (1) that can be located on the pin of a spectacle (2), which incorporates a front camera (4), for capturing video images, and a signal processor (14), with transmitter of light after a liquid crystal display (LCD) that projects the captured image to the active area of the user's field of view (10) using one or two reflection prisms (6), depending on the position of the light source which it is activated and modulated by means of the sensor (12). An optical filter of selective absorbance with respect to short wavelengths is incorporated in order to protect the retina.

To accommodate the reduced field of vision of the patient, the device incorporates a simple ballpoint system (8) and a gluttony axis (9) for the two-dimensional translation of the optical imaging system.

In this way, the user can place the reflection prism (6) by hand to more accurately position the projected image (7) in the most appropriate area of the user's visual field (10).
