Abstract: The present disclosure provides methods and apparatuses for loading program data on to an unpowered electronic device, such as an RFID tag that includes volatile memory. Initially, the tag is unpowered. Thus, the volatile memory in the tag will not have any stored data. In order to load data into the memory of the tag, a reader can power the tag wirelessly. The reader includes an antenna configured to transmit electromagnetic radiation and receive backscatter electromagnetic radiation. The reader also includes a processing unit. The processing unit is configured to analyze the backscatter electromagnetic radiation. The processing unit may analyze the backscatter radiation to determine a supply voltage induced in the tag. In response to the induced voltage being greater than a threshold, the processing unit may alter the transmitted electromagnetic radiation to communicate tag data.

Abstract: Techniques and mechanisms for determining a direction of gaze by a user of an eye-mountable device. In an embodiment, the eye-mountable device includes a first circuit and a second circuit, each comprising a respective photodiode. The second circuit is configured to provide a light response profile that is more linear than a light response profile provided by the first circuit. Light sensing by the first circuit results in generation of a first signal indicating a level of ambient light in a surrounding environment. Other light sensing by the second circuit results in a second signal being generated. A direction of gaze by a cornea of the user is detected based at least in part on the first signal and the second signal. In another embodiment, the first signal is provided to configure the second circuit.
