The system includes a sensing device that allows the timing of a heating period for the pressure controlled device based on temperature and/or pressure values sensed inside the pressure controlled device. A RFID tag is coupled to the sensing device and is operable for generating timing information. The sensing device and the RFID tag are powered by a nano electromechanical (NEM) device that is operable by a source of pressurized air.

Abstract: A method and system for identifying an authentication status of a first item. An RFID reader transmits zero and a random number to a first RFID tag associated with the first item. The first RFID tag uses a hashing function to compute a hash (H1) of a concatenation of an identifier (Id1) of the first RFID tag, the random number, and a first secret key and sends the hash H1 to the RFID reader which then transmits the identifier Id1 and the random number to a second RFID tag. The second RFID tag uses the hashing function to compute a hash (H2) of a concatenation of the identifier Id1, the random number, and a second secret key and sends the hash H2 to the RFID reader. The authentication status of authentic or counterfeit is determined for the first item based on whether or not H1 is equal to H2.

Abstract: A cooling management system including component racks, a cooling system, pressure measurement devices, and a computing system within a structure. Each component rack includes an exothermic apparatus. The structure includes warm air aisle spaces and cold air aisle spaces located between the component racks. The cooling system feeds cold air into each cold air aisle space. The cold air flows through the component racks resulting in displacement of warm air from each exothermic apparatus. The warm air flows into the warm air aisle spaces and is directed back to the cooling system. The pressure measurement devices measure differential pressure values between the cold air aisle spaces and the warm air aisle spaces. The computing system monitors the differential pressure values, perform calculations associated with the differential pressure values, and control a fan speed of at least one fan within the cooling system based on the calculations.

Abstract: A ballot paper and a voting system. The paper ballot is initially a voted ballot paper including: a recorded vote including candidate/party information for an election on a voting day in a jurisdiction, a burnable radio frequency identification (RFID) tag including a fuse not blown, and a basic RFID tag storing the jurisdiction's signature. The recorded vote is not revealable while the fuse is not blown and is revealable responsive to the fuse being blown. The voting system includes a ballot box and a ballot counting machine. The ballot box is configured to receive and authenticate the voted ballot paper and to generate a verified ballot paper. The ballot counting machine is configured to receive and authenticate the verified ballot paper, to effectuate a blowing of the fuse to reveal the recorded vote and to subsequently count the ballot paper and direct the ballot paper to a candidate box.

Abstract: 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.

Abstract: RFID tag and a system and method involving a plurality of RFID tags. Each RFID tag is attached to an object on which the presence of a predefined fluid is monitored. In a first state, (absence of the monitored fluid), the tag acts as a passive RFID tag, and the information it holds can be read with a proximity reader. This operation is performed when the RFID tag is attached to the object to be monitored. In a second state, whenever the monitored fluid appears on the tagged object, a fluid activated battery generates the electrical power which is used to power the RFID tag. The RFID tag then acts as an active RFID tag and starts to emit messages which can be received by a RFID reader.

Abstract: The present invention describes a RFID tag and a system and method involving a plurality of RFID tags. Each RFID tag is attached to an object (or to a structure or a person) on which the presence of a predefined fluid is monitored. In a first state, (absence of the monitored fluid), the tag is acting as a passive RFID tag, and the information it holds, (at least its identifier—ID), can be read with a proximity reader (a hand held or stationary/fixed reader). This operation is performed when the RFID tag is attached to the object (or person) to be monitored. At this stage a table associating tag ID, object name (or person name) and location (or any other information), may be built, and may be recorded so that information it contains is accessible by a control center. In a second state, whenever the monitored fluid appears on the tagged object, a fluid activated battery generates the electrical power which is used to power the RFID tag.

Abstract: 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.

Abstract: Method and system for localizing an object in a stack of objects. A passive radio frequency identification (RFID) tag is attached to each object. Each RFID tag includes a unique identifier of the object to which the RFID tag is attached. A RFID reader has multiple antennas. Each antenna is positioned to transmit a signal that can be detected by different RFID tags attached to the objects within a reading range of the transmitted signal from each antenna. The antennas are sequentially selected and powered to transmit to the stack a read signal including object's identifier for the object to be localized. If a response to the read signal is received by a selected and powered antenna from a RFID tag that matched the object's identifier with its unique identifier, then a light emitting diode (LED) is lighted to identify a location of the object being localized.
