Reader communication with contact lens sensors and display device

摘要

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.

主权项

1. A method, comprising:
transmitting, by a reader, radio frequency (RF) power to a sensing device, wherein the sensing device is physically separated from the reader, and wherein the sensing device includes a sensor configured to obtain measurements related to glucose in a bodily fluid; communicating with the sensing device, by the reader, using a first wireless protocol, wherein communicating with the sensing device comprises requesting and receiving one or more measurements by the sensor; determining first calibration data based on an identifier of the sensing device; determining a glucose concentration in the bodily fluid based on the one or more measurements and the first calibration data, wherein determining the glucose concentration in the bodily fluid based on the one or more measurements and the first calibration data comprises determining the glucose concentration in the bodily fluid by a processing system in the reader, wherein the processing system comprises one or more processors and one or more storage components; receiving user input from a user of the sensing device; responsive to receiving the user input, determining second calibration data specific to the user, wherein determining second calibration data specific to the user comprises determining two different blood glucose levels for the user; determining a blood glucose concentration based on the glucose concentration in the bodily fluid and the second calibration data; and providing, by a user interface, an indication of the blood glucose concentration.
