  • Patent number: 9328943
    Abstract: Systems, methods, and devices for integrated detector cooler assemblies (IDCAs) and multi-circuit cryostats are discussed herein. Solutions include using cryostats with multiple cooling circuits. Some cryostat variations may include a rapid cooldown circuit and a temperature maintenance circuit. In some cases, the temperature maintenance circuit may be a closed-loop circuit run by a compressor instead of an open-loop circuit run on a pressurized gas bottle/cartridge. Variations of a cryostat may also include a gas expander portion that replaces the coldfinger of typical IDCAs. Further variations of cooling circuits may include circuits that perform reverse-flow heat exchange to pre-cool incoming refrigerant and also cooling circuits that have heat bridges disposed thereon to assist in such heat exchange.

  • Patent number: 7106173
    Abstract: Tags, wireless communication systems, tag communication methods, and wireless communications methods are described. In one aspect, a tag includes a plurality of antennas configured to receive a plurality of first wireless communication signals comprising data from a reader, a plurality of rectifying circuits coupled with. respective individual ones of the antennas and configured to provide rectified signals corresponding to the first wireless communication signals, wherein the rectified signals are combined to produce a composite signal, an adaptive reference circuit configured to vary a reference signal responsive to the composite signal, a comparator coupled with the adaptive reference circuit and the rectifying circuits and configured to compare the composite signal with respect to the reference signal and to output the data responsive to the comparison, and processing circuitry configured to receive the data from the comparator and to process the data.

  • Patent number: 6995652
    Abstract: A system and method for controlling remote devices utilizing a radio frequency identification (RFID) tag device having a control circuit adapted to render the tag device, and associated objects, permanently inoperable in response to radio-frequency control signals. The control circuit is configured to receive the control signals that can include an enable signal, and in response thereto enable an associated object, such as a weapon; and in response to a disable signal, to disable the tag itself, or, if desired, to disable the associated weapon or both the device and the weapon. Permanent disabling of the tag can be accomplished by several methods, including, but not limited to, fusing a fusable link, breaking an electrically conductive path, permanently altering the modulation or backscattering characteristics of the antenna circuit, and permanently erasing an associated memory.
