A system includes an electronic contact lens that obtains sensor measurements from integrated motion sensors or other types of sensors and a processing module that estimates a mental state of an individual based on the sensor measurements. The processing module identifies patterns of eye movements and analyzes how these patterns change over time. Based on anatomical relationships between eye movement and mental state, the processing module estimates characteristics of the individual such as fatigue, intoxication, injury, or a medical condition that have known effects on eye movement patterns. The electronic contact lens system generates an output indicative of the estimated mental state to alert the individual to the detected condition or to initiate an automated action.

An electronic module is provided. The electronic module includes a first transducer and a second transducer. The first transducer is configured to radiate a first ultrasonic wave. The second transducer is configured to radiate a second ultrasonic wave. The first transducer and the second transducer are disposed on noncoplanar surfaces.

Smart glasses are provided in the present disclosure, including a housing, a fixing bracket, a left lens barrel, a right lens barrel, an object distance adjustment mechanism including a left-eye object distance adjustment gear, a right-eye object distance adjustment gear, an object distance adjustment driving gear engaged with the left-eye object distance adjustment gear and the right-eye object distance adjustment gear and a driving motor driving the object distance adjustment driving gear to rotate and being capable of moving back and forth on the fixing bracket along a second direction; a pupil distance adjustment mechanism connected to at least one lens barrel, and configured to drive the lens barrel to move in the first direction when an external force is applied, and a linkage member arranged between the at least one lens barrel and the driving motor.

A method, performed by an augmented reality (AR) device including a vision correction lens, of detecting a gaze of a user is provided. The method includes obtaining lens characteristic information about the vision correction lens arranged to overlap a light guide plate in a gaze direction of the user, emitting light for gaze tracking toward a light reflector through a light emitter, wherein the emitted light is reflected by the light reflector and then directed to an eye of the user, receiving a light reflected by the eye of the user through a light receiver, obtaining an eye image of the user based on the light received, adjusting the eye image of the user based on the lens characteristic information about the vision correction lens, and obtaining gaze information based on the adjusted eye image.

A type of fragrant eyeglasses is revealed. The fragrant eyeglasses include an eyeglass body and a nose bridge which is arranged at the eyeglass body and provided with a mounting space for mounting fragrance tablets. At least one air inlet and at least one air outlet for guiding air flows are disposed on a front side and a rear side of the mounting space respectively. Thereby the fragrance tablet mounted in the nose bridge is just adjacent to the user's nose when the eyeglasses are fitted on bridge of user's nose by the nose bridge. Thus the user smells scents emanated from the fragrance tablet and feels refreshing and soothing. The air inlet and the air outlet not only help emanation of scents from the fragrance tablet, but also guide the scents to spread along with air flows induced by movements of people who while walking or riding bicycles.

Described herein are systems and methods that allow for secure wireless communication between a contact lens system and an accessory device to protect sensitive data and prevent unauthorized access to confidential information. In certain embodiments, tampering attempts by potential attackers are thwarted by using a Physically Unclonable Functions (PUF) circuit that is immune to reverse engineering. In addition, sensors monitor a to-be-protected electronic device to detect tampering attempts and physical attacks to ensure the physical integrity of the communication system.

The present invention relates to a stereo eye tracking technique. The eye tracking device comprises a processing unit configured and operable for receiving at least one image being indicative of a user's eye; identifying in the image a first data being indicative of pupil's parameters; receiving a second data being indicative of an alternative eye tracking, wherein the second data is more accurate than the first data; and correlating between the first and second data and determining a three-dimensional position and gaze direction of the user's eye.

A process of overmolding a frame of a portable eyewear electronic device and a frame produced by the process is presented. A frame that includes a first material and includes a releasably mountable feature is attached to the mold in a desired position and does not contact other areas of the mold. The mold is filled with a second material to at least partially encase the frame insert.

A floatation attachment system may include a floatation attachment device configured to be attached to an object. The floatation attachment device may include a floatation material configured to provide buoyancy to the object it attaches and an attachment surface configured to directly attach the object. The floatation material may include a material that expands or generates gas upon contact with water. The system may include a dispenser such as a sheet of pre-cut floatation attachment devices or for manual cutting for customized shapes and sizes. In one instance, the system includes a tape roll dispenser for dispensing floatation attachment devices from a roll.
