Abstract: Techniques and mechanisms for providing access to an accommodation-capable eye-mountable device via a user interface of an auxiliary device. In an embodiment, the user interface provides prompts for a user of the eye-mountable device to perform various viewing actions, where the eye-mountable device receives from the auxiliary device communications indicating respective times of the viewing actions. Based on the communications, the eye-mountable device generates configuration information indicating a correspondence of respective states of the eye-mountable device to respective characteristics of the viewing actions. In another embodiment, operational modes of the eye-mountable device are defined based on the configuration information.

Abstract: A method of capacitive gaze detection for accommodation includes monitoring at least one capacitance value of a capacitive sensor system disposed within a contact lens. The at least one capacitance value varies in response to changes in a gazing direction of a cornea upon which the contact lens is removeably mounted. The changes in the gazing direction of the cornea are detected in real-time based upon changes in the at least one capacitance value. An accommodation actuator disposed within the contact lens is manipulated to automatically change an optical power of the contact lens in response to detecting changes in the gazing direction.

Abstract: Disclosed herein are methods and systems for adjusting the power level of an external reader of an electronic device. The external reader transmits power to the electronic device with a radio frequency electromagnetic signal. The electronic device may rectify the radio frequency electromagnetic signal and create a rectified voltage. The rectified voltage may be positively correlated to the power level transmitted by the external device. The rectified power can be used to power a component of the electronic device, such as a component configured to measure either a voltage or power associated with the rectified voltage. The electronic device may communicate the measured voltage or power back to the external reader. Based on the communicated voltage or power, the external reader may adjust its power level of the transmitted power.

Abstract: An eye-mountable device includes an electrochemical sensor embedded in a polymeric material configured for mounting to a surface of an eye. The electrochemical sensor applies a stabilization voltage between a working electrode and a reference electrode to allow the amperometric current to stabilize before powering measurement electronics configured to measure the amperometric current and communicate the measured amperometric current. The electrochemical sensor consumes less power while applying the stabilization voltage than during the measurement. The measurement is initiated in response to receiving a measurement signal at an antenna in the eye-mountable device.

Abstract: A wearable device includes a sensor, auxiliary electronics, a primary power supply configured to harvest radio frequency (RF) radiation received from an external reader and use the harvested RF radiation to power the sensor, and an auxiliary power supply configured to harvest energy other than that received from the external reader and use the harvested energy to supply power to the sensor and/or the auxiliary electronics. The external reader may supply less power in response to operation of the auxiliary power supply. Additionally or alternatively, in response to a determination that the auxiliary power supply is unable to supply power, the wearable device may disable all auxiliary electronics but for the sensor. In response to a determination that the primary power supply is unable to supply power but the auxiliary power supply is able to supply power, the wearable device may retain operating parameters in the memory storage unit using the auxiliary power supply.

Abstract: The present disclosure provides methods and apparatuses for providing an audible feedback based on a proximity or a link quality between an external reader and a tag. The external reader transmits power to the tag with a radio frequency electromagnetic signal. The tag may rectify the radio frequency electromagnetic signal and create a rectified voltage. This rectified voltage may be used to power various components of the tag. Once it receives power from the reader, the tag may communicate information back to the external reader. The information communicated back to the reader is communicated by modulating an antenna impedance of the tag. By modulating the impedance, the tag will backscatter radiation transmitted by the reader. The reader is able to create an audio output based on determining the proximity or link quality from the reader to the tag based on the backscatter radiation it receives from the tag.
