    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: A system includes an oscillator referenced to a frequency extracted from periodic intensity modulations of incident light. The incident light can be intensity modulated based on the frequency of the AC voltage that powers artificial lighting. The system includes a light-sensitive element configured to generate an output signal indicative of an intensity of incident light and a controller. The controller can receive a first input signal based on the output signal from the light-sensitive element. In the presence of artificial lighting, the first input signal has a frequency based on a reference frequency at which an intensity of light incident on the light-sensitive element periodically varies. The controller can generate a control signal based in part on the reference frequency. The controller can provide the generated control signal to the adjustable oscillator to thereby adjust the oscillator frequency.
