    摘要: A masterless time slot allocation technique that collaboratively synchronizes, at a time slot level, devices communicating in an ad hoc network. Responsive to determining a current time slot allocated to a first device is occurring, the first device transmits a map to the other devices. The map includes an allocation of time slots to the devices, including indicators for whether each time slot is free, busy or overbooked, devices that own the time slots, and how recently information associated with each time slot was updated. After receiving the map, a second device determines a conflict in which the same time slot is allocated to the second device and to another device. The conflict is resolved by allocating another time slot to the second device and the result of resolving the conflict is each slot is allocated to no more than one device.

    摘要: A transponder, a method for powering the transponder, and a system relating to the method. The transponder includes at least two electrical coils, a dipole antenna, and a chip electrically connected to the dipole antenna and the electrical coils, wherein the electrical coils surround the dipole antenna and the chip. The transponder is surrounded with a wiring loop. An alternating current is generated in the wiring loop. The alternating current generates a magnetic field at the electrical coils. The electrical coils receive energy from the magnetic field and transfer the received energy to the chip for powering the transponder. The dipole antenna is configured to transmit an output signal to a reader and to receive an input signal from the reader.

    摘要: A method and system for dividing a set of tagged items into subsets. Each tagged item is tagged with a passive RFID tag. A RFID reader is instructed to poll the RFID tags of all tagged items in a specified region having fixed boundaries to generate information including, for each tagged item, a spatial location of each tagged item and a list of all other tagged items in the region which are adjacent to each tagged item. The region is split into a plurality of subregions. For each subregion, a central tagged item having more adjacent tagged items in each subregion than any other tagged item in each subregion is determined, utilizing the generated information. A virtual boundary is outlined around the central tagged item to enclose the central tagged item and a portion of the tagged items in each subregion which are adjacent to the central tagged item.

    摘要: RFID method and system are provided. A reader transmits a reader signal to beacon tags and a listening tag. The beacon tags transmit beacon signals including a beacon identification and a beacon distance to the reader. The listening tag receives the beacon signals. Neighbor distances are calculated for the beacon tags based on when the beacon signals are received, when the listening tag receives the reader signal, and a constant processing time. The neighbor distances are the individual distances from the listening tag to the beacon tags. A list is stored including the beacon identification for the beacon tags, the beacon distance, and the neighbor distances. The listening tag transmits the list and a listening tag identification to the reader. A geographical position of the listening tag is calculated based on the beacon distance, beacon coordinates, and a listening tag distance which is from the reader to the listening tag.

    摘要: A Radio Frequency Identification (RFID) structure. The RFID structures includes a tag stack of N essentially identical RFID tags and an object stack of N essentially identical objects. N is at least 2. Each tag is attached to a corresponding object and includes an electronic chip, an antenna, and at least one pair of electrical contacts. The N tags are daisy chained together in electrical contact via the at least one pair of electrical contacts in the tags. The tag stack is configured to receive power from an external power source located outside of the RFID structure. A method for localizing an object in the object stack includes receiving an external signal in each tag via the antenna, and enabling or not enabling a lighting of a lighting device in each tag in dependence upon data in the external signal.

    摘要: A method and RFID tag for locating RFID tags. A passive RFID tag A receives a polling command transmitted from a RFID reader and addressed to another passive RFID tag B. The RFID tag A determines that the polling command is not addressed to the RFID tag A and consequent1y, at time t1, switches the RFID tag A to a catching mode for catching echos from other tags. The RFID tag A receives at time t3>t1 an echo of a message sent by the RFID tag B to the RFID reader. The RFID tag A determines a distance (D.t2t) between the RFID tag A and the RFID tag B based on t3 minus t1. The distance D.t2t does not exceed a specified radius limit and the identification of the RFID tag B and the distance D.t2t are stored in a database within the RFID tag A.
