Wireless smart iris system

Abstract

The application discloses a wireless intelligent iris system, which comprises a controller and an electronic corneal contact lens located on the visual axis, and the controller is wirelessly connected with the electronic corneal contact lens. The controller comprises a light intensity sensor, a microprocessor and a wireless energy emission module. The electronic corneal contact lens comprises a wireless energy receiving module, a ring-shaped transparency adjustable diaphragm and a corneal contact lens front base and back base for encapsulating the wireless energy receiving module and the transparency adjustable diaphragm. The light intensity sensor on the controller converts the environmental light intensity into an electric signal and transmits the electric signal to the microprocessor. The microprocessor controls the electric energy to act on the specific diaphragm through the wireless energy emission module and the wireless energy receiving module on the electronic corneal contact lens, thereby independently controlling the visible light transmittance of each layer of diaphragm.

Description

Technical Field

[0001] This invention relates to the field of optometry technology, specifically to a wireless intelligent iris system. Background Technology

[0002] The iris plays a crucial role in controlling the diameter and size of the pupil, thereby controlling the amount of light reaching the retina. An intact iris is essential for achieving maximum visual quality; it reduces aberrations caused by the lens or peripheral cornea, minimizes excessive glare from the light entering the eye, and increases depth of focus. However, some congenital (congenital iris defects) or acquired (penetrating iris injury, iris tumor resection, inflammatory damage, drug-induced blockage of pupillary dilator and sphincter muscle contraction) factors can lead to iris defects, pupillary changes from a normal round shape to an irregular shape, or the iris's inability to properly adjust the pupil diameter, resulting in conditions such as glare, loss of contrast sensitivity, and loss of best-corrected visual acuity. Currently, most patents propose implantable irises based on intraocular lenses or artificial irises based on contact lenses. For example, Chinese patent CN102599991A discloses the application of a cosmetic corneal contact lens, which is the preparation of a corneal contact lens for occlusion. However, none of these artificial irises can change the size of the light-transmitting aperture as needed, nor can they intelligently adjust the light-transmitting aperture according to the intensity of ambient light without human intervention. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a wireless intelligent iris recognition system.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A wireless intelligent iris recognition system includes a portable controller and an electronic corneal contact lens wirelessly connected to the controller.

[0006] The controller includes:

[0007] A light intensity sensor is used to acquire the light intensity of the external environment and convert the light intensity signal into an electrical signal;

[0008] The microprocessor processes and interprets the electrical signals generated by the light intensity sensor. Based on the light intensity detected by the sensor, it determines whether it is necessary to output drive current to the wireless power transmitter.

[0009] The wireless power transmitter, driven by the current generated by the microprocessor, transmits wireless power to the wireless power receiving module of the corneal contact lens.

[0010] The electronic corneal contact lens includes:

[0011] Anterior base of corneal contact lens;

[0012] Several annular transparent adjustable apertures with different radii are superimposed on the posterior surface of the anterior base of the corneal contact lens and are arranged circumferentially around the pupil area, and each annular transparent adjustable aperture can be controlled individually;

[0013] The wireless energy receiving module, located on the outside of the annular adjustable transparency aperture, can convert wirelessly transmitted energy into electrical energy, thereby independently adjusting the transparency of each annular adjustable transparency aperture.

[0014] The back base of the corneal contact lens is superimposed on the rear surface of the energy receiving module.

[0015] The annular transparent adjustable aperture includes a front annular electrode, a rear annular electrode, and a transparency adjustment layer disposed between the front annular electrode and the rear annular electrode, and the front annular electrode and the rear annular electrode are respectively electrically connected to the wireless power contact module.

[0016] The annular adjustable transparency aperture is arranged circumferentially around the smallest pupil area, and there is no gap between adjacent annular adjustable transparency apertures.

[0017] The diameter of the minimum pupil area is 2 mm.

[0018] The microprocessor is a rigid or flexible information processing circuit.

[0019] The wireless signal is light energy, electromagnetic field, magnetic field or electric field.

[0020] The controller can be installed on eyeglass frames, clothing, accessories, or the user's vehicle, belongings, or electronic products.

[0021] The controller's light intensity sensor is separately configured from the microprocessor and the wireless energy transmitter, and the light intensity sensor is connected to the microprocessor and the wireless energy transmitter via wired or wireless means.

[0022] The beneficial effects of this invention are as follows: The light intensity sensor on the controller converts ambient light intensity into an electrical signal, which is transmitted to the microprocessor. After judgment, the microprocessor controls the electrical energy to act on specific apertures through the wireless energy transmitting module and the wireless energy receiving module on the electronic corneal contact lens, thereby independently controlling the visible light transmittance of each aperture layer. As the transparency of the aperture gradually expands from the inner circle to the outer circle, the light entering the eye can be adjusted, thereby improving vision and visual comfort.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0028] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or a connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two elements or the interaction between two elements, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0029] As shown in the figure, the present invention discloses a wireless intelligent iris system, which includes a portable controller located on the visual axis and an electronic corneal contact lens wirelessly connected to the controller. The controller is preferably a wearable eyeglass frame, but can also be clothing, jewelry, headphones, or other items. It can be used to obtain the light intensity of the external environment and then adjust the transparency of the electronic corneal contact lens.

[0030] The controller includes:

[0031] Light intensity sensor 1 is used to acquire the light intensity of the external environment and convert the light intensity signal into an electrical signal. It can be a photoelectric sensor.

[0032] Microprocessor 4 outputs a control signal containing output power based on the light intensity of the external environment detected by the light intensity sensor.

[0033] Wireless power transmitter 3 transmits wireless signals of varying power based on control signals from the microprocessor.

[0034] The light intensity sensor, microprocessor, and wireless power transmitter can be integrated into one product or set up separately, and the two are connected by wired or wireless means.

[0035] It also includes a battery and power management module. The battery is a disposable battery, a rechargeable battery, or a capacitor. The power management module is used to protect and manage the battery.

[0036] The electronic corneal contact lens 5 includes:

[0037] The corneal contact lens anterior base 6 has a thickness of less than 100 micrometers and is made of transparent material to further reduce the impact on visual perception. It is shaped into a curved disc, which has a concave surface on one side for mounting an annular transparent adjustable aperture and a wireless power receiving module. The annular transparent adjustable aperture and the wireless power receiving module are distributed around the pupil area of ​​the corneal contact lens anterior base and are sequentially attached to the concave surface of the corneal contact lens anterior base. The pupil area is a circular area with a diameter of 0.5 mm to 8 mm.

[0038] Several annular transparent adjustable apertures 7 are overlapped with the posterior surface of the anterior base of the corneal contact lens and are arranged circumferentially around the pupil area, and each annular transparent adjustable aperture can be controlled individually;

[0039] The wireless power receiving module 8 is located outside the annular transparent adjustable aperture and can independently adjust the transparency of each annular transparent adjustable aperture according to the different power wireless signals sent by the wireless power transmitter.

[0040] The posterior base 9 of the corneal contact lens is made of a transparent material with a thickness of less than 100 micrometers to further reduce the impact on visual perception. It is shaped into a curved disc with one side having a concave surface suitable for fitting onto the corneal surface of the eye. When installed in the eye, it does not interfere with eyelid movement. The circumferential direction of its convex surface fits circumferentially with the concave surface of the anterior base of the corneal contact lens, and the color change module and the energy receiving module are enclosed in the sealed space formed by the two.

[0041] The wireless energy transmission system (including a wireless energy transmitter in the controller and a wireless energy receiver in the electronic corneal contact lens) is a system capable of wireless energy transmission through light energy, electromagnetic fields, magnetic fields, electric fields, and others, and its receiver can generate electrical energy through the acquired energy.

[0042] The wireless power receiving module and the transparent adjustable aperture are very thin and integrated into the contact lens, without affecting the base curve, thickness, diameter, oxygen permeability, surface hydrophilicity and flexibility of the contact lens itself. Therefore, the wearing comfort and biosafety of this type of contact lens can be ensured to the greatest extent.

[0043] The annular transparent adjustable aperture 7 includes a front annular electrode 71, a rear annular electrode 73, and a transparency adjustment layer 72 disposed between the front annular electrode and the rear annular electrode. The front annular electrode and the rear annular electrode are electrically connected to the wireless power contact module, respectively.

[0044] The transparency adjustment layer is a material or module capable of adjusting visible light transmittance under energy-driven action. Its color-changing material employs inorganic materials such as WO3, TiO2, Nb2O5, MoO3, Ta2O5, NiO, IrO2, MnO2, V2O5, and Prussian blue, as well as organic materials such as polythiophene, polypyrrole, polyaniline, and polyindole. Under the influence of energy (such as temperature or electrical energy), these materials undergo changes in band gap and optical contrast due to electron or ion implantation or electrochemical doping, thereby controlling the change in visible light transmittance.

[0045] When conductive materials (such as organic conductive materials like polythiophene and polypyrrole, or inorganic conductive components like carbon nanotubes, metal particles, and nanowires) are mixed into a flexible film, the conductive paths formed by the conductive components under the action of electrical energy cause uneven deformation of the elastic film, thereby increasing the surface roughness, forming diffuse reflection, and reducing the visible light transmittance.

[0046] Both the front and rear annular electrodes are transparent structures. They are transparent conductors with a visible light transmittance of more than 30%, prepared on polyimide films, polyethylene terephthalate films, polyurethane films, and polyethylene naphthalate films using one-dimensional or two-dimensional conductive materials such as transparent conductive oxides, silver nanowires and fibers, and carbon nanotubes and fibers.

[0047] The annular adjustable transparency aperture is set circumferentially around the smallest pupil area, and there are no gaps between adjacent annular adjustable transparency apertures to ensure full coverage and prevent gaps from affecting the adjustment effect.

[0048] The diameter of the minimum pupil area is 2mm to ensure that the aperture of light entering the pupil area is minimized under the strongest light intensity environment, thus playing a protective role.

[0049] The microprocessor can be a rigid or flexible information processing circuit, designed according to requirements.

[0050] Example

[0051] Composition of a wearable wireless intelligent iris recognition system: Figures 1 to 4The image shows a wearable wireless intelligent iris recognition system. This system consists of a facepiece frame 2 (integrating a battery, power management system, microprocessor 4, photoelectric sensor 1, and wireless energy transmitter 3) and an electronic corneal contact lens 5 (integrating a wireless energy receiver module and an adjustable-transparency ring) worn on the ocular surface. The battery is a disposable battery, a rechargeable battery, or a capacitor. The microprocessor is a rigid or flexible information processing circuit. The photoelectric sensor is a photodetector that converts light intensity signals into electrical signals. The wireless energy transmission system (wireless energy transmitter and wireless energy receiver module) is a system capable of wireless energy transmission via light, electromagnetic fields, magnetic fields, electric fields, and others. The adjustable-transparency ring is a material or module that adjusts visible light transmittance under energy-driven action. The transparent electrode is a conductive material with a visible light transmittance higher than 30%.

[0052] How to use the wearable wireless smart iris system: The power module in the frame drives the microprocessor and photoelectric sensors. The photoelectric sensors continuously convert changes in ambient light intensity into electrical signals and transmit them to the microprocessor. The microprocessor processes and judges the information. When the ambient light is weak, the microprocessor controls all apertures to maximize visible light transmittance through the wireless power transmission system. As the ambient light gradually increases, the microprocessor controls the visible light transmittance of the apertures to decrease through the wireless power transmission system. This change gradually extends from the outer aperture to the inner aperture. When the ambient light is extremely strong, the microprocessor controls all apertures to minimize visible light transmittance through the wireless power transmission system. Through this series of changes, the aperture of light entering the eye (e.g., Figure 5 (As shown).

[0053] Figure 1 and Figure 2 This is just one possible construction scheme for a wireless intelligent iris recognition system. Alternatively, the photoelectric sensor can be integrated into the user's clothing, accessories, headphones, and other personal items. The microprocessor and wireless power transmitter can be integrated into the user's personal belongings or surrounding items (including but not limited to vehicles, robots, drones, office supplies, and furniture). Information is transmitted between the photoelectric sensor and the microprocessor via wired or wireless communication. The wireless power receiving module and the annular adjustable aperture can be integrated not only into contact lens platforms but also into scleral lenses, bandage lenses, intraocular lenses, and other wearable or implantable devices located on the visual axis.

[0054] The embodiments should not be regarded as limitations on the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
