  • Anti-aliasing photodetector system
    Patent number: 9909922
    Abstract: 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.

  • Wake circuit for powered ophthalmic lens
    Patent number: 9535266
    Abstract: A wake circuit is designed to minimize leakage current from a battery or other suitable energy source connected to various electronic components. The wake circuit essentially connects/disconnects or couples/decouples the battery or other power source from the other components when the device is in a storage state or otherwise idle.
