59 results about "Closing eyes" patented technology

A system and method are provided for monitoring an eye to determine eye closure. The system includes a video imaging camera oriented to generate images of an eye, and a video processor for processing the images. The processor includes an edge detector for detecting edges of the eye in the image, and a line selector for generating lines at any of select angles representative of the detected edges. The processor determines the state of eye closure, such as an open eye or closed eye, based on an angle between two of the lines that select angles. The system may be employed on a vehicle to determine the eye closure state of a driver of the vehicle.

The invention discloses a driving standardization monitoring system for locomotive drivers, which is a system that enables online real-time intelligent identification and further can standardize the standardization operation of locomotive drivers during driving. A monitoring system receives a command of a LKJ analysis service item to drive an audio output device to prompt the locomotive driver tooperate in time; drive an image acquisition equipment to collect the gestures of the driver and carry out intelligent analysis in real time, meanwhile, score the gestures of the driver in the serviceitem; and drive an audio acquisition equipment to collect the call and response voices of the driver and carry out intelligent analysis in real time, meanwhile, score the call and response phrases ofthe driver in the service item. If the driver does not make a gesture, does not make a call or a response, or the score is low, the monitoring system notices a data transmission subsystem to send thedata (audio clip, recognition result, LKJ information) to a ground analysis system. When the driver is operating, a look-out state visual recognition service detects the look-out state of the driver in real time. If the driver closes eyes, looks left and right, leaves the position, or yawns and so on, the service drives the audio output device to promptly remind the driver to look-out, and send the violation situation to a ground analysis unit through the data transmission subsystem.

A contact lens shaped measuring device (1) includes sensor (3) having a protrusion (14) towards the cornea (22). The measuring device (1) is flexible to a degree that it is flattened by a closing eye lid and the protrusion creates an indentation of the cornea. The occurring force on the protrusion is measured by the sensor. Applying a constant lid acceleration / deceleration model to the movement of the lid and a mechanical model to the cornea, the tension of the cornea is determined and deduced from the force measured with the lid closed, yielding the true intraocular pressure. In an alternative, the protrusion is characterized by a discontinuity in its shape, or the sensor is subdivided, each subsensor being characterized by a protrusion of different shape. With the values obtained as extrema and at the discontinuity or with different protrusions, the cornea tension can be obtained by a (linear) extrapolation.

The invention discloses an eye-drops bottle neck, and relates to a packaging bottle containing eye drops. The packaging bottle comprises a bottle body, a dropping neck, wherein the dropping neck is peripherally provided with a bottle cap, and the external part of the bottle body dropping neck is provided with a flaring eye-support device. When the eye-drops bottle neck is in use, eyes are opened, and the eye-support device is buckled on the eyes, because of the support effect of the eye support device, even if closing eyes subconsciously can not enable the eyes close completely, and because of the positioning effect of the eye support device, the liquid medicine can be dropped in by extruding a liquid medicine bottle.

The embodiment of the present invention provides a fatigue driving detection method and device and relates to the technical field of fatigue recognition. The method comprises a step of acquiring detected face image information, a step of calculating an offset of a center of gravity of a head of a driver and an effective number of closing eyes of the driver in a unit time based on the face image information, and a step of determining a driving state of the driver according to the offset of the center of gravity of the head and the effective number of closing eyes. Whether the driver is in a fatigue driving state or not can be accurately judged by integrating the offset of the center of gravity of the head and the effective number of closing eyes to reduce cases of misjudgment, and the safety of the driver and passengers is guaranteed to a greater extent.

The invention relates to eye washing equipment, in particular to ophthalmic eye washing equipment. The invention provides the ophthalmic eye washing equipment which can help a patient to fix eyelids after the patient opens eyes and automatically wash eyes. The invention provides such ophthalmic eye washing equipment comprising a supporting frame, a seat, a supporting plate, a baffle and supportingpillars, wherein the seat for a patient to sit during eye washing is arranged on one side of the top of the supporting frame; the supporting plate is arranged on one side of the top of the supportingframe, which is away from the seat; one side of the supporting plate is connected with one side of the seat; the baffle is arranged on one side of the seat; the baffle is positioned on the lower sideof the supporting plate; the supporting pillars are arranged on both sides of one side of the top of the baffle in a sliding mode; and both the supporting pillars penetrate through the top of the baffle. By matching of an eye opening mechanism, an eye washing mechanism and an intermittent water draining mechanism, a case that people cannot control to close the eyes in the eye washing process to delay treatment of people can be avoided, and water can be controlled to flush out and stop at any time in the eye washing process.

The invention relates to a design method for big visual angle imaging device of close observing video influence. The feature is that the lens observing body has display, projection lens, reflector, projection screen, and amplifying eyepiece. The display is video display, and lens cover and condensing lens of reflecting back light source are contained at the back of display liquid circuit. The invention makes the display have big visual angle displaying effect, and it is low cost, light, etc.

The present invention relates to the field of ICU nursing techniques, and particularly relates to an eye closure aid for patients in an intensive care unit (ICU). The eye closure aid comprises an eyeclosure aid outer frame of which both sides are fixedly connected with a binding belt. The adjustable eye closure aid outer frame has a rectangular hollow structure, and a silicone eye protection padis fixedly attached on the rear side edge of the adjustable eye closure aid outer frame. The hollow part of the adjustable eye closure aid frame is slidably connected with an eye closure aid togglingmechanism. The eye closure aid can help the patient to close eyes, so as to prevent accelerated moisture evaporation in eyes of the patient and damage due to dust, sands in the air and bugs entering the eyes since the eyes can not close. During wearing, the eye closure aid of the invention does not injure human skin, and is more humanistic.

The invention provides an eyedrop bottle frame. The eyedrop bottle frame comprises a frame body, a frame cover, two supporting units and a placement unit, wherein the supporting units and the placement unit are arranged in the frame body; the two supporting units are the same in structure and are arranged on the two sides in the frame body respectively; the placement unit is arranged in the middle of the two supporting units of the same structure; the structure comprises supporting frameworks; a bracket is arranged in each supporting framework; a bracket head is hinged at the bottom of the corresponding bracket; each bracket head adopts a smooth round ball shape; one side of the corresponding bracket head is connected with the side wall of the bracket through a spring piece; a disinfection illuminating lamp is arranged on the top of each supporting framework; the placement unit comprises a spring set at the bottom of the frame body; the eyedrop bottle can be sleeved with the spring set; and an opening is formed in the bottom of the framework below the spring group. By adoption of the eyedrop bottle frame, the problem that a user closes eyes when the eyedrop is applied to eyes can be solved; the eyedrop can be applied to eyes accurately; after the eyedrop is used, the eyedrop can be disinfected; and in addition, the eyedrop bottle frame is capable of keeping the eyedrop sanitary and clean, simple, and easy to operate.
