Controllers for dry eye treatment apparatus and methods are described herein which generally comprise a patch or strip affixed to the skin of the upper and / or lower eyelids to deliver heat to the one or more meibomian glands contained within the underlying skin. The treatment strip or strips include one or more strips configured to adhere to an underlying region of skin in proximity to one or both eyes of a subject such that the one or more strips allow for the subject to blink naturally without restriction from the one or more patches. A controller is in communication with the one or more strips and is programmable to monitor a temperature of the one or more strips to provide a treatment therapy above a threshold temperature of, e.g., 39° C., and below a maximum temperature of, e.g., 48° C., over a treatment period of 12 minutes.

Systems and methods for eyelid shape estimation are disclosed. In one aspect, after receiving an eye image of an eye (e.g., from an image capture device), an eye-box is generated over an iris of the eye in the eye image. A plurality of radial lines can be generated from approximately the center of the eye-box to an upper edge or a lower edge of the eye box. Candidate points can be determined to have local maximum derivatives along the plurality of radial lines. From the candidate points, an eyelid shape curve (e.g., for an upper eyelid or a lower eyelid) can be determined by fitting a curve (e.g., a parabola or a polynomial) to the candidate points or a subset of the candidate points.

The invention discloses a driver fatigue detection system and method based on Bluetooth transmission. A photoelectric Bluetooth mouse device is made into a glasses additional device mounted on a glasses frame, the relative moving direction, moving distance and movement speed of each upper eyelid can thus be obtained, and these information is transmitted to external terminal equipment having the Bluetooth communication function through a Bluetooth communication module; the external terminal equipment processes the moving track to obtain eyelid winking data, and the external terminal equipment transmits the eyelid winking data to a remote monitoring server through the Internet; by processing and analyzing the eyelid winking data, the remote monitoring server judges the driving state of a driver, and according to the analysis result, whether voice prompt information needs to be sent to the driver or not is determined. According to the system and the method, real-time acquisition, transmission and processing are conducted in sequence on the eyelid winking information of the driver, whether the driver is in fatigue driving or not is judged, and the voice prompt information is sent when the driver is in fatigue driving.

Disclosed is a composition for use for topical administration onto the upper and / or lower eyelid of a subject.

A pupil detecting apparatus detects an edge of a pupil in an image of a face. An outline of an upper eyelid is also detected. The apparatus selects an effective edge extending along the pupil by removing a part of edge extending along the upper eyelid from the edges detected. Then, the apparatus applies the circle Hough transformation to the effective edge in order to obtain a center of the pupil and a radius of the pupil. Thereby, it is possible to detect the pupil accurately even if a part of the pupil is covered.
