Embodiment Construction

[0018] One aspect of the present disclosure provides a method for loading program data onto an unpowered electronic device including volatile memory, such as an RFID tag. After the tag is manufactured and shipped, the tag will not be powered. Therefore, the volatile memory in the tag will not be powered. In order to load data into the tag's volatile memory, the tag may be provided with sufficient power for memory operations. In an example embodiment, an external reader device, or "reader," may radiate radio frequency radiation to power the tag. The reader, in turn, can control the operation of the tag by controlling the power supply to the tag. In some examples, the reader may be operable to intermittently interrogate the tag to provide a reading by irradiating enough radiation to power the tag to obtain a measurement and communicate the result.

[0019] An external reader may be used to transmit power to the tag with a radio frequency signal or an extremely low frequency (...

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.

Description

[0001] related application [0002] This application claims priority to US Patent Application Serial No. 14 / 303,674, filed June 13, 2014, entitled "Zero-Power Wireless Device Programming," which is hereby incorporated in its entirety. Background technique [0003] Unless otherwise indicated herein, the materials described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section. [0004] The size of some electronic devices is so small that a power supply source cannot reasonably accompany the device. In these instances, the electronic device may receive power from an external power source. The external power supply may be configured to wirelessly supply power to the electronic device. Furthermore, due to both their small size and power constraints, electronic devices can be configured with volatile memory. Volatile memory can store data only when power is supplied to the memory. Therefore, if the ...
