The training method adopts the device for training. According to the wearable eyelid closing training device and training method, physiologic and quantifiable effects can be achieved, immediate feedback is achieved, and therefore the training effect is improved.

The utility model discloses an eye structure of a robot and the robot, and relates to the technical field of robots, the eye structure of the robot and the robot comprise an eyeball, an upper eyelid located above the eyeball and a lower eyelid located below the eyeball, the upper eyelid and the lower eyelid are both of an arc-shaped spherical shell structure, the two ends of the upper eyelid and the two ends of the lower eyelid are provided with relative overlapping areas which serve as rotation axes of the upper eyelid and the lower eyelid. The eyelid driving assembly is used for driving the upper eyelid to be close to the lower eyelid or driving the lower eyelid to be close to the upper eyelid; and the transmission assembly is positioned on one side of one of the overlapped areas. The rotating speed of the upper eyelids is larger than that of the lower eyelids, and the rotating speed is characterized in that the opening and closing amplitude of the upper eyelids is larger than that of the lower eyelids, so that the eye structure of the robot better conforms to the blinking action of a human body.

The invention discloses an electromyographic signal remote monitoring method and system, and relates to the technical field of electromyographic signal monitoring, and the method comprises the following steps: 1, continuously collecting original electromyographic signals of upper eyelid skin of a current patient in the eye opening and closing process through a flexible microelectrode array attached to the surface of the upper eyelid skin of the current patient, and outputting the original electromyographic signals as electromyographic data, the method comprises the following steps: step 1, acquiring basic information data of a current patient from a medical information terminal, and acquiring physiological data of the current patient at the same time, step 2, calling myoelectricity data, lesion states and corresponding physiological data of historical patients from a hospital database, and performing analysis in combination with historical similar patient data. Therefore, the current lesion state of the patient is more accurately judged, the accuracy and reliability of the lesion analysis process are greatly improved, a doctor can more deeply know the condition of the patient and formulate a corresponding treatment scheme, and the treatment effect on the patient is improved.

This invention discloses an eyelid detection method, apparatus, device, and storage medium. The method involves acquiring a first eye event image and a second eye event image. The first eye event image is an image captured by an event-driven DVS camera when the eye is illuminated by a first set of infrared light sources, and the second eye event image is an image captured by the same DVS camera when the eye is illuminated by a second set of infrared light sources. The first and second sets of infrared light sources are alternately illuminated. The positions of the upper and lower eyelids are determined based on the first and second eye event images. The eyelid detection method provided by this invention determines the positions of the upper and lower eyelids based on two eye event images acquired when the eye is illuminated by two alternately illuminated sets of infrared light sources, thereby improving the accuracy and efficiency of eyelid detection.

The utility model relates to an auxiliary tool for double-fold eyelid design, which comprises a first supporting rod, a second supporting rod, a third supporting rod and a fourth supporting rod, one end of the second supporting rod is connected with one end of the first supporting rod, the included angle between the first supporting rod and the second supporting rod is set to range from 75 degrees to 80 degrees, the length of the second supporting rod is set to be 10 mm, and scale marks are arranged on the surface of the second supporting rod. By means of the first supporting piece and the second supporting piece which are precisely designed, the design accuracy is remarkably improved.
