Abstract: Authentication of a user is based on an electronic contact lens that contains a retinal scanner. The retinal scanner captures a retinal scan, which is used to authenticate the user (i.e., what a person is). The contact lens itself may also be used in the authentication process (i.e., what a person has). Authentication based on these two factors are used to control access to assets.

Abstract: A scleral contact lens has a core containing an optical filter. The core and/or the optical filter may comprise oxygen impermeable material, such that an overall oxygen permeability of the core is insufficient to oxygenate a user's cornea when wearing the contact lens. To provide oxygenation to the user's cornea, the contact lens further comprises an outer covering, and an inner covering, each corresponding to a thin layer of gas-permeable material shaped to form a respective manifold between the covering and the core. Oxygen from an outside environment passes through the outer covering to reach the outer manifold, through an air path formed within the core to the inner manifold, and through the inner covering to reach the cornea of the user's eye.

Abstract: A system includes a pair of electronic contact lenses that obtain respective motion sensor measurements in response to eye movements. A tracking module derives estimated orientations for both eyes based on the sensor measurements and a set of correlations and constraints that describe human eye movement. The model describes the limited number of ways that an individual eye can move and relationships between relative movement of the left and right eye. The tracking module performs filtering based on the measurements and the eye model to suppress noise and generate orientation estimates for both eyes.

Abstract: An electronic intraocular device is implantable into the capsular bag of a wearer's eye. In some cases, the intraocular device may include a femtoprojector. The femtoprojector projects images onto the wearer's retina when the electronic intraocular device is implanted in the wearer's eye. Different haptic designs may be used to keep the femtoprojector in position. In some embodiments, an imager is contained in a contact lens worn by the wearer. Images captured by the contact lens imager may be relayed to the intraocular femtoprojector. In some cases, the intraocular device may include an electronic capsular tension ring with a femtoimager. The femtoimager may capture images of the wearer's retina, for example for purposes of monitoring eye health.

Abstract: A system for agricultural monitoring and prediction comprises a first reporting agent a second reporting agent a database, and a processor. The first reporting agent is configured for reporting aerial data representing relative measurements of an agricultural metric in a geographic area, the relative measurements having an unknown bias. The second reporting is configured for reporting ground-based data representing absolute measurements of the agricultural metric for a portion of the geographic area. The database is configured for storing the absolute measurement data and the relative measurement data along with other farming data for a wide geographic area. The processor is configured for accessing the database and using the ground-based data for the portion of the geographic area to calibrate the aerial data, thereby synthesizing absolute measurements of the agricultural metric for the geographic area from the aerial data.
