Abstract: Backscatter communication includes receiving electromagnetic energy from a base station and encoding first data and second data. The first data is encoded at a first frequency by adjusting a radar cross-section of a device to modulate the electromagnetic energy reflected back to the base station. The second data is encoded at a second frequency by limiting the adjusting of the plurality of radar cross-sections to either a first subset or a second subset of the plurality of radar cross-sections for a length of time. The second frequency is lower than the first frequency.

Abstract: A method of capacitive gaze detection for accommodation includes monitoring at least one capacitance value of a capacitive sensor system disposed within a contact lens. The at least one capacitance value varies in response to changes in a gazing direction of a cornea upon which the contact lens is removeably mounted. The changes in the gazing direction of the cornea are detected in real-time based upon changes in the at least one capacitance value. An accommodation actuator disposed within the contact lens is manipulated to automatically change an optical power of the contact lens in response to detecting changes in the gazing direction.
