Abstract:
A body-mountable device can include a transparent material and a substrate at least partially embedded in the transparent material. The transparent material can have a mounting surface and a surface opposite the mounting surface. A light source can be disposed on the substrate and configured to emit light through the surface opposite the mounting surface. The light source can be controlled by circuitry disposed on the substrate. The circuitry can be configured to receive modulation instructions and modulate the light emitted by the light source based on the modulation instructions.
Abstract:
Methods and systems for using unique identifiers to retrieve configuration data for tag devices are described herein. An example method may involve obtaining a unique identifier associated with a tag device. The tag device may include an antenna and a sensor configured to obtain sensor readings that can be wirelessly transmitted to a reader device via the antenna. The method may also involve determining configuration parameters associated with the tag device based on the unique identifier. The method may further involve storing, in at least one memory, at least a portion of the configuration parameters in association with the unique identifier.
Abstract:
A reader for communicating with both an eye-mountable device and a display device is provided. The reader can transmit radio frequency power to a tag that is part of the eye-mountable device. The reader can communicates with the tag using a first protocol. Communicating with the tag can include having the reader request data from the tag and receive the requested data from the tag. The reader can process the received data. The reader can store the processed data. The reader can communicates with the display device using a second protocol, where the first and second protocols can differ. Communicating with the display device can include having the reader transmit the stored data to the display device. The display device can receive the transmitted data, process the transmitted data, and generate one or more displays including the transmitted and/or processed data.
Abstract:
An eye-mountable device includes a controller embedded in a polymeric material configured for mounting to a surface of an eye. The controller is electrically connected to an antenna included in the eye-mountable device. The controller is configured to: (i) receive an indication of an interrogation signal via the antenna, (ii) responsive to the interrogation signal, output a substantially unique identification sequence; and (iii) use the antenna to communicate the substantially unique identification sequence. The substantially unique identification sequence can then be used by external readers to associate the eye-mountable device with device-specific information without storing such information on the eye-mountable device.
