Abstract: A device for communicating data with a contact lens through a communication interface is disclosed. In embodiments of the invention, an accessory device identifies one or more wireless channels to communicate with a contact lens. Scheduling of this wireless communication is performed such that a preferred channel is selected based on noise and/or interference. In certain embodiments, a centralized scheduler, such as a Wi-Fi access point, is used to reserve the preferred channel within the associated wireless network so that clients within the network don't use this channel.

Abstract: 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.

Abstract: Embodiments of the disclosure relate to a low-power, high-data-rate, radio transceiver inside a contact lens. The radio transceiver includes a phase-locked loop having a frequency acquisition loop that turns on and off based on various performance characteristics of the transceiver. The transceiver also includes wireless power harvesting circuitry that receives a wireless power signal and generates a reference signal that is used by an oscillator within the transceiver.

Abstract: A temporary part is mounted onto the chuck of the diamond turning machine. A diamond turning tip of the diamond turning machine is used to form a reference surface on the temporary part, registering a baseline for a motion control system of the diamond turning machine. While the temporary part remains mounted to the diamond turning machine, a workpiece is mounted onto the temporary part, and the diamond tip is controlled relative to the reference surface to diamond turn a surface profile on the workpiece. Because the baseline established by the reference surface compensates for positional variations from mounting parts directly onto the chuck of the diamond turning machine, the length of the workpiece can be shaped to a designated length with a high degree of accuracy.

Abstract: A contact lens structure provides adequate corneal oxygenation while accommodating a relatively thick core with electronic devices. In one approach, an oxygen collection stratum, such as a gas-permeable outer layer coupled with an underlying air gap, collects oxygen from the ambient air. On the cornea-side, an oxygen distribution stratum, such as a gas-permeable inner layer coupled with an overlying air gap, provides distribution of oxygen to the cornea. The two strata are connected via a network of oxygen pathways, such as air shafts through the relatively impermeable core. Thus, the oxygen collection stratum collects oxygen over a portion of the outer surface of the contact lens, which is transmitted through most of the thickness of the contact lens via the oxygen pathways to the oxygen distribution stratum, where the oxygen is distributed to the cornea of the wearer.

Abstract: A display device is mounted on and/or inside the eye. The eye mounted display contains multiple sub-displays, each of which projects light to different retinal positions within a portion of the retina corresponding to the sub-display. The projected light propagates through the pupil but does not fill the entire pupil. In this way, multiple sub-displays can project their light onto the relevant portion of the retina. Moving from the pupil to the cornea, the projection of the pupil onto the cornea will be referred to as the corneal aperture. The projected light propagates through less than the full corneal aperture. The sub-displays use spatial multiplexing at the corneal surface. Various electronic devices interface to the eye mounted display.

Abstract: A display device (e.g., in a contact lens) is mounted on the eye. The eye mounted display contains multiple sub-displays, each of which projects light to different retinal positions within a portion of the retina corresponding to the sub-display. Additionally, a “locally uniform resolution” mapping may be used to model the variable resolution of the eye. Accordingly, various aspects of the display device may be based on the locally uniform resolution mapping. For example, the light emitted from the sub-displays may be based on the locally uniform resolution mapping.
