20110012668 | PROGRAMMABLE EFUSE AND SENSE CIRCUIT - A circuit for electric fuses includes circuits for sensing status and programming that have separate paths for each operation. The circuit includes a plurality of electrically programmable fuses and, associated with each fuse, a switch for coupling a first terminal of the fuse to a ground supply for programming or to a comparator for sensing. The circuit uses a switched current source to supply current to the fuses for programming. The comparator senses a fuse status when a current source is switched through the fuse. The comparator compares a voltage across the fuse and associated switches to a comparison voltage across a comparison resistor and switches included for matching. | 01-20-2011 |

20100231382 | WIRELESS TEMPERATURE SENSOR NETWORK - A wireless temperature sensor network includes a base station unit which transmits query signals cyclically addressing a plurality of temperature sensor transponder units. The transponder units are passive and derive operating power from the query signal to encode measured temperature data into a reply signal which is received by the base station. In a dual carrier embodiment, the query signal and reply signals are transmitted on separate frequencies. In a backscattering embodiment, the antennas of the transponder units can be switched between an absorption mode in which the query signal is received and a reflection mode in which the query signal is reflected back to the base station. The transponder antennas are switched in such a manner as to encode temperature data in the reflected signal to form a reply signal. The network embodiments are particularly applicable to space based platforms. | 09-16-2010 |
