Abstract: An RFID tag tuning circuit may be capable of adjusting the impedance matching between an RFID integrated circuit (IC) and an antenna on an RFID tag to increase the amount of power that the IC can extract from an incident RF wave. The tuning circuit switches a variable impedance coupling the antenna and the IC between several different impedance settings, where each impedance setting differs from an adjacent impedance setting by a respective impedance step size and at least one impedance step size has a different value than another impedance step size. The tuning circuit may switch the variable impedance by incrementing through a counter, decrementing through the counter, or performing some search algorithm. The tuning circuit may also initialize the variable impedance based on a default impedance setting or a random impedance setting derived from a random counter.

Abstract: RFID system components, such as readers and tags, communicate by a reader transmitting waveforms that encode a calibration symbol and a divide ratio. Tags include a processor to determine a backscatter link period result by dividing a count value representing the calibration symbol by the divide ratio and adding an adjustment. Tags modulate a backscatter waveform that includes symbols using a link period determined from the result.

Abstract: RFID readers, systems, and methods are provided for overcoming the effects of RF interference. While a system is communicating in a channel, RF interference is monitored. If it is low, then hopping to another channel is performed according to an ordinary decision. But if interference is high, then hopping out to another channel can be earlier than would be dictated by the ordinary decision under the same circumstances. The earlier hopping out can result in diminishing communication in channels with a lot of RF interference.

Abstract: RFID readers, systems, and methods are provided for overcoming the effects of RF interference. While a system is communicating in a channel, RF interference is monitored. If it is low, then the next channel to be hopped onto is chosen in an unbiased manner. But if interference is high, then the next channel to be hopped onto is chosen in a biased manner that disfavors at least one channel over another, in view of the detected interference. The choice of the next channel can thus result in diminishing communication in channels with a lot of RF interference.

Abstract: Methods and apparatus provide secure two-way (reader-to-tag and tag-to-reader) RFID communications. According to one aspect, a tag receives a noise-encrypted RF carrier signal from a reader and backscatter modulates it with tag information. Eavesdroppers cannot extract the tag information from the backscattered signal because it is masked by the noise encryption.

Abstract: Methods and apparatuses prevent overtunneling in nonvolatile floating gate memory (NVM) cells. An individual cell includes a circuit with a transistor that has a floating gate that stores charge, and a capacitor structure for extracting charge from the gate, such as by tunneling. A counteracting circuit prevents extracting charge from the floating gate beyond a threshold, therefore preventing overtunneling or correcting for it. In one embodiment, the counteracting circuit supplies electrons to the floating gate, to compensate for tunneling beyond a point. In another embodiment, the counteracting circuit includes a switch, and a sensor to trigger the switch when the appropriate threshold is reached. The switch may be arranged in any number of suitable ways, such as to prevent a high voltage from being applied to the capacitor structure, or to prevent a power supply from being applied to a terminal of the transistor or to a well of the transistor.

Abstract: RFID readers, computers, and methods are provided for reporting on the authentication of one or more RFID tags associated with a proffered item, while requiring special permissions be cleared before reporting. In some embodiments, a question is input about whether a Declared Password (DP) is regarded as proper for an Item Identifier (II), both of which have been input from the tags. An answer is generated for the question from the reference database, and transmitted to the user. The answer does not reveal an Actual Code that is indeed regarded as proper, unless the user first demonstrates they already know it. Beyond the authentication of the tag, the answer can further indicate the legitimacy of the proffered item, for a supply chain, at a Customs Office, etc.

Abstract: Methods are provided for handling items in a supply chain, or at a checkpoint such as a Customs Office. When an item is proffered, it is associated with one or more RFID tags. If an authentication condition about the tag data is met, the item is accepted, but otherwise it is rejected. In some embodiments, the authentication condition is that the one or more RFID tags store an Item Identifier (II), and a Declared Password (DP) that is regarded as proper for the II, as per a reference database. Security is accomplished by making the data of the reference database available subject to special permissions.

Abstract: RFID readers, computers, and methods are provided for determining the authentication of one or more RFID tags associated with a proffered item. In some embodiments, an Item Identifier (II) is input from the tags, along with a Declared Password (DP) corresponding to the II. A question is generated about whether the DP is regarded as proper for the II by a reference database, and applied to data of the reference database. A host of the database uses special permissions, such that an answer to the question does not reveal the good password, unless the DP is already the right one. Beyond the authentication of the tag, the answer can further indicate the legitimacy of the proffered item, such as for a supply chain or at a Customs Office.

Abstract: RFID tags are commanded to generate a pilot tone in their backscatter. When the backscattered pilot tone is received in the reader, the pilot tone is used to estimate the tag period/frequency. Then, the estimate is used to seed and lock a symbol timing recovery loop, which provides a detected signal to one or more correlators for detecting the tag preamble. A delayed version of the received tag signal is compared against a baseline signal threshold established from the received signal to detect the pilot tone.

Abstract: Radio frequency identification (RFID) tags selected for inventorying using combination of preselect and/or post select criteria. The selection commands can be for selecting according to a tag memory content, by invoking the mask address or by comparing other tag characteristics. Selection criteria can be determined locally at a modem block of a reader or provided to the modem block by higher layers of the reader. Tags meeting the selection criteria are reported to the higher layers for further actions. Some tags may be held while waiting for instructions from the higher layer block(s).

Abstract: RFID readers exchange information with RFID tags. The information is encoded for transmission and decoded upon reception. Encoding is in binary bits, which are in turn encoded in waveform segments. The last transmitted waveform incorporates an ending-triggering transition, and terminates in a preset manner with respect to when the ending-triggering transition occurs. Parsing while decoding can happen by waiting for the ending-triggering transition, and then waiting according to the preset manner. This way there is no ambiguity in the ending of the waveform, and no End Frame is necessary.

Abstract: Methods and apparatuses for programming a single-poly pFET-based nonvolatile memory cell bias the cell so that band-to-band tunneling (BTBT) is induced and electrons generated by the BTBT are injected onto a floating gate of the cell. Following a predetermined event, the single-poly pFET is biased to induce impact-ionized hot-electron injection (IHEI). The predetermined event may be, for example, the expiration of a predetermined time period or a determination that a channel has been formed by the BTBT injection process that is sufficiently conducting to support IHEI. Employing BTBT permits a previously overerased or stuck bit to be “unstuck” or “removed” and thus be made usable (i.e., able to be programmed) again.
