摘要： An RFID reader controller and methods of controlling an RFID reader by an RFID reader controller are provided to limit or prevent the issuing of confidential information such as encryption keys, passwords, shared secrets, and the like to RFID tags if a reader is not authorized. A controller may determine the authorization status of a reader and limit its communication with the reader or instruct the reader to limit an operational aspect of the reader.

摘要： RFID reader systems, readers, components, software and methods for causing RFID tags to backscatter a combination made from at least portions of a first code and a second code stored in tag memory, without transmitting any commands in the interim. In a number of embodiments, therefore, a separate command does not have to be sent for also reading the second code, thereby saving time in inventorying the tags. Plus, the combination can enable reading tag codes during tag manufacturing that are not otherwise readily available to read in the field.

摘要： RFID tags and chips for RFID tags store a first code and a second code in memory. They are capable of backscattering a combination made from at least portions of the first code and the second code, without receiving any commands in the interim. In a number of embodiments, therefore, a separate command does not have to be sent for also reading the second code, thereby saving time in inventorying the tags. Plus, the combination can enable reading tag codes during tag manufacturing that are not otherwise readily available to read in the field.

摘要： A precursor for a Radio Frequency Identification (RFID) tag includes a conductive lead frame with at least three segments, an RFID Integrated Circuit (IC) with at least two antenna terminals, and at least two jumpers. The RFID IC is mounted on at least one of the segments. The antenna terminals are electrically coupled to at least two of the segments, and the jumpers electrically couple the segments such that the coupled segments form a two-turn coil between the antenna terminals of the RFID IC.

摘要： A system and method for generating a rectified signal in a RFID tag. An alternating signal is received by the RFID tag, and a first phase of the alternating signal is coupled to a gate and to a first non-controlling terminal of a first switching transistor. The non-controlling terminal of the first switching transistor is one of a source and a drain of the first switching transistor. A first bias voltage is applied between the first non-controlling terminal and the first gate of the first switching transistor and a rectified voltage is received between the first non-controlling terminal and a second non-controlling terminal of the first switching transistor.

摘要： A circuit for an RFID tag has at least two RF ports for driving points of the antenna that may correspond to different RF polarizations. The RF ports may be driven by a common modulating signal, or by separate modulating signals. Further, the ports may be coupled and uncoupled together, responsive to a control signal. The control signal may be the same as one or both of the modulating signals.

摘要： Systems, software, devices, and methods are described for an RFID reader system to communicate with RFID tags. RF energy encountered in conjunction with using a selected channel is detected. The RF energy can be a signal from another RFID reader. The detected signal is used to adjust a waveform shaping parameter. RF waves can be transmitted from the reader to the RFID tags and RF waves can be backscattered from the RFID tags. At least some of the RF waves transmitted to or backscattered from the RFID tags have a waveform with a shape according to the adjusted waveform shaping parameter.

摘要： 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.
