    摘要: An ophthalmic lens assembly comprising an electronic system with a controller configured to implement a blink detection algorithm is described herein. The electronic system can also include one or more power sources, circuitry, one or more sensors, clock generation circuitry, control algorithms, and lens driver circuitry. The algorithm can be used to sample, at a predetermined rate, light incident on an eye of an individual and at least temporarily save collected samples, determine when an eyelid is open or closed, determine a time period and pulse width of the blinks from the collected samples, calculate a number of blinks and the duration of the blinks in a given time period, and compare the number of blinks, the durations of the blinks in the given time period, and the time between blinks in the given time period to a stored set of samples to determine blinking patterns.

    摘要: An anti-aliasing photodetector system for a powered ophthalmic device, such as a contact lens, may be utilized for any number of functions. The anti-aliasing photodetector system converts current from an array of photodetectors into a voltage for use in other aspects of the powered ophthalmic device. The anti-aliasing photodetector system comprises a photodiode array including a plurality of individual photodiodes, an integrate-and-hold circuit, including a capacitor and switch to convert current to voltage, and an analog-to-digital converter. The anti-aliasing photodetector system provides for low power consumption, a wide dynamic range, noise rejection, and is capable of detecting incident ambient visible light as well as incident infrared light.

    摘要: A blink detection algorithm and associated circuitry for an ophthalmic lens comprising an electronic system is described herein. The blink detection algorithm is implemented in the system controller which is part of an electronic system incorporated into the ophthalmic lens. The electronic system includes one or more batteries or other power sources, power management circuitry, one or more sensors, clock generation circuitry, control algorithms and circuitry, and lens driver circuitry. The blink detection algorithm implements the steps of sampling, at a predetermined rate, light incident on an eye of an individual and at least temporarily saving collected samples, determining when an eyelid is open or closed in order to divine the number, time period and pulse width of the blinks from the collected samples, calculating a number of blinks and the duration of the blinks in a given time period, and comparing the number of blinks, the durations of the blinks in the given time period, and the time between blinks in the given time period to a stored set of samples to determine patterns in blinking.
