WIRELESS COMMUNICATION BETWEEN A CONTACT LENS AND AN ACCESSORY DEVICE
First Claim
1. An accessory device for managing wireless communication with a contact lens, the device comprising:
- a controller;
a battery coupled to the controller;
a memory coupled to the controller;
an interference determination unit coupled to the controller, the interference determination unit scans a communication environment to determine interference characteristics across a plurality of wireless channels; and
a scheduler coupled to the controller, the scheduler communicates with a Wi-Fi access point and is provided a time window within a wireless channel, the scheduler schedules a communication with the contact lens in the provided time window within the wireless channel, wherein the communication comprises;
scanning a communication environment to determine interference characteristics of a plurality of wireless channels;
communicating with a Wi-Fi access point to coordinate sharing a wireless channel within a Wi-Fi network;
communicating data with a contact lens through a shared wireless channel; and
responsive to failing to share a wireless channel, sending a data packet to the contact lens through a wireless channel that has a least interference, wherein sending the data packet comprises;
waking up form a sleep mode;
choosing a wireless channel that is not being used by a Wi-Fi access point;
sending the data packet to the contact lens through the chosen wireless channel; and
determining whether an acknowledgement signal from the contact lens is received.

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.
