A method for streaming sensor data from a set of radio-frequency identification (RFID) tags includes determining an initial communication approach to be performed with respect to each RFID tag. The method also includes managing access to the RFID tag by refining the initial communication approach based on records of successes and failures of the initial communication approach. A radio-frequency identification (RFID) system is also disclosed, the system comprising one or more processors and a memory system comprising one or more non-transitory computer-readable media storing instructions that, when executed by at least one of the one or more processors, causes the system to perform operations for streaming sensor data from one or more RFID tags to one or more RFID readers.

Internal radio-frequency instrumentation system and method

A system includes a plurality of radiofrequency identification (RFID) tags including a first RFID tag. The first RFID tag is configured to perform RFID tag operations that include acquiring one or more samples using a sensor of the first RFID tag. The RFID tag operations also include writing the one or more samples in a memory of the first RFID tag. The RFID tag operations also include transferring custody of the one or more samples to a first RFID reader on request. The system also includes a plurality of RFID readers including the first RFID reader. The first RFID reader is configured to perform RFID reader operations including reading an identifier from each of the plurality of RFID tags in view of the first RFID reader during an inventory management mode.

System and method for wearable, ubiquitous RFID-enabled sensing

A sublimator includes a sublimation plate having a thermal element disposed adjacent to a feed water channel and a control point disposed between at least a portion of the thermal element and a large pore substrate. The control point includes a sintered metal material. A method of dissipating heat using a sublimator includes a sublimation plate having a thermal element and a control point. The thermal element is disposed adjacent to a feed water channel and the control point is disposed between at least a portion of the thermal element and a large pore substrate. The method includes controlling a flow rate of feed water to the large pore substrate at the control point and supplying heated coolant to the thermal element. Sublimation occurs in the large pore substrate and the controlling of the flow rate of feed water is independent of time. A sublimator includes a sublimation plate having a thermal element disposed adjacent to a feed water channel and a control point disposed between at least a portion of the thermal element and a large pore substrate. The control point restricts a flow rate of feed water from the feed water channel to the large pore substrate independent of time.
