Abstract: Various embodiments are described that relate to global position and time information. Two devices can be in communication with one another. The first device can be able to communicate with a satellite system while the second device is unable to communicate with the satellite system. The second device can send a request for global position and time information at a first time that is received by the first device at a second time. At a third time, the first device can send the global position and time information that is received by the second device at a fourth time. The second device can use the first time, second time, third time, and fourth time to compensate for delay caused by the request being sent and the arrival of the information.

Abstract: A temperature-sensitive thermal cutoff fuse RFID tag is provided with a bimorph element and thin conductive bridges positioned on an RFID tag substrate that can react to all changes in storage temperature conditions. The bimorph element is configured and positioned so that when it bends in response to one or more predetermined temperatures, the bimorph element will break one of the conductive bridges and cause an open circuit that can be detected when the RFID tag is interrogated by a sensor. The temperature-sensitive thermal cutoff fuse RFID tag can provide high and low temperature information about numerous stored objects such as food, medicine, chemicals, batteries, explosives and munitions. Multiple temperature conductive bridge cutoff fuse RFID tag arrangements and methods for notifying the user when a required storage temperature has been reached with a passive temperature-sensitive thermal cutoff fuse RFID tag.

Abstract: A humidity-sensitive cutoff fuse RFID tag is provided with a bimorph element and thin conductive bridges positioned on an RFID tag substrate that can react to all changes in storage humidity conditions. The bimorph element is configured and positioned so that when it bends in response to one or more predetermined humidity levels, the bimorph element will break one of the conductive bridges and cause an open circuit that can be detected when the RFID tag is interrogated by a sensor. The humidity-sensitive cutoff fuse RFID tag can provide humidity information about numerous stored objects such as food, medicine, chemicals, batteries, explosives and munitions. Multiple humidity conductive bridge cutoff fuse RFID tag arrangements and methods for notifying the user when a predetermined storage humidity limit has been reached with a passive humidity-sensitive cutoff fuse RFID tag are provided. Since it does not require power to operate, the cutoff fuse is suitable for monitoring a long-term storage condition.

Abstract: A sensor for sensing a property of an analyte includes a QCM resonator that has a crystal substrate that includes an electrode depositing surface and an analyte contact surface that are physically separated. The resonator further includes a plurality of electrodes operatively connected with the electrode depositing surface and laterally spaced apart one from another.

Abstract: A sensor for sensing a property of a plurality of analytes includes a substrate having a resonant frequency that varies based on contact with a predetermined property of an analyte. The substrate has an analyte contact surface and a non-analyte contact surface located opposed to the analyte contact surface. The analyte contact surface is configured to receive a plurality of analytes. A plurality of pairs of electrodes are operatively connected with the nonanalyte contact surface, each of the electrodes being spaced apart one from another.

Abstract: A surface acoustic wave device sensor configured so as to have at least two different modes of operation. An acoustic response is obtained from each of the different modes of operation. The different modes of operation are a combination of a temperature effect and a measurand effect. The measurand effect is caused by the absorption and/or adsorption of a substance into a selective coating on the piezoelectric substrate. The two different modes of operation are effected differently by the temperature effect and therefore can be used to effectively eliminate the temperature effect by simultaneously solving equations representative of the different modes of operation. The present invention eliminates the need to provide other relatively more complicated temperature compensating structure or to maintain the device at a predetermined constant temperature. The present invention can be used to detect different chemicals or substances.
