I have discovered cosmetic or topical pharmaceutical compositions for external body part or organ slimming, firming, cellulite reduction, fat-reduction, and obesity control benefits that are in synergistic combination with benefits for the treatment of skin aging, skin wrinkles reduction, skin exfoliating, treatment of acne, treatment of rosacea, age-spots reduction, skin surface whitening, skin surface brightening striae distensae (stretch marks) reduction, treatment of pimples, treatment of skin infections and lesions, spider veins reduction, blood microcirculation (venous insufficiency) improvement, UVA / UVB protection of skin, and skin redness reduction. These compositions thus provide multiple combinations of skin and external body part or organ enhancement benefits that can be selective and specific for external body parts and organs such as face, chin, cheeks, arms, "love handles" in abdomen area, eye lids and eye zone, neck, breasts, thighs, and hips. These compositions include a body beneficial composition selected from certain nutraceutical, cosmetic, and pharmaceutical ingredients, a composition to promote collagen and elastin synthesis in the skin, and a cosmetically or pharmaceutically acceptable delivery system.

False eyelashes for attachment to the edge of an eyelid. The false eyelashes include a plurality of lashes arranged in a curved state; and an attachment section formed by applying an adhesive to one end of the lashes, the attachment section being formed such that the lashes are not knotted together at the attachment section. A plurality of the false eyelashes are applied to the edge of an eyelid of each eye.

Apparatus for monitoring movement of a person's eye, e.g., to monitor drowsiness. The system includes a frame that is worn on a person's head, an array of emitters on the frame for directing light towards the person's eye, and an array of sensors on the frame for detecting light from the array of emitters. The sensors detect light that is reflected off of respective portions of the eye or its eyelid, thereby producing output signals indicating when the respective portions of the eye is covered by the eyelid. The emitters project a reference frame towards the eye, and a camera on the frame monitors movement of the eye relative to the reference frame. This movement may be correlated with the signals from the array of sensors and / or with signals from other sensors on the frame to monitor the person's level of drowsiness.

The present invention is related to a method for designing and making a contact lens which comprises stiffening rib features that provide even distribution of pressure from the lens over the cornea of an eye and / or allows the lens structure to maintain balance of forces for consistent and correct lens orientation on an eye during lens translation or eye lid movement. The invention also provides a soft contact lens comprising stiffening rib features that provides localized directional reinforcements to the lens structure to evenly distribute pressure from the lens over the cornea of an eye and / or to maintain balance of forces for consistent and correct lens orientation on an eye during lens translation or eye lid movement.

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 pose of the eye in the eye image is determined. From the eye pose, an eyelid shape (of an upper eyelid or a lower eyelid) can be estimated using an eyelid shape mapping model. The eyelid shape mapping model relates the eye pose and the eyelid shape. In another aspect, the eyelid shape mapping model is learned (e.g., using a neural network).

The invention provides a biopsy method for use in human face identification and belongs to the technical field of mode identification. The algorithm provided by the invention comprises: firstly, giving a 'please-face-the-camera-with-face' prompt to a user logging in regardless of the current posture of the user, finding the face and eye socket areas by using an Adaboost human face sorter during the posture correction of the user, determining upper and low eyelids and left and right eye corners by using differential projection and precisely framing the positions of the eye sockets; secondly, computing optical flow field of two adjacent frames in an input video sequence by using an LK algorithm; and thirdly, further processing obtained optical flow data to obtain an optical flow amplitude, acquiring the number of the pixels with high amplitude, computing the specific gravity of the pixels with high amplitude, and determining eye movement if the proportion is big. Experiments show that for a real human face, eye movement can be detected easily due to a heavy optical flow generated on the eyes in a posture correction and eye twinkling process, while for a picture, eyes only perform a micro movement no matter how the picture moves or translations. When the method is used for biopsy, a better effect can be obtained.

An alertness monitoring system includes: means to measure velocity and amplitude of eyelid and eye movement; and storage means to continuously record the measurements. A data processor calculates the blink amplitude to velocity ratio and / or the saccade amplitude to velocity ratio and compares the measurements against a predetermined scale. The scale is derived from averaged measurements of the eye and eyelid movement parameters for a sample population measured against predetermined incremental blood alcohol levels. The output of the system can include a display for showing the alertness measurement based on the scale, or an alarm means triggered by the scale reading reaching a predetermined limit based an the blood alcohol level scale.

Artificial eyelashes having improved adhesive for easy application, comfortable use, and repeated wear. The eyelashes include a rolled projecting part that provides adjustability in angle and a suitable contour for the eyelid. The lashes may be reused, including refill tapes for protection of the adhesive portion of the eyelashes when such lashes are not in use.
