Abstract: 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.

Abstract: A smoke detector system employs smoke detectors that enter a “lockout period” following receipt of an alarm signal, during which time a detector will not receive a RF alarm signal and will not transmit a RF alarm signal after a certain period of time if that detector does not detect, or no longer detects, a dangerous condition. The lockout period is of sufficient duration to prevent re-transmission of a RF alarm signal by a detector even though it may have received a RF alarm signal from another detector(s). Hence, after a short period of time, no RF alarm signals will be received or transmitted and each detector resets, unless a dangerous condition is detected.

Abstract: A nonvolatile memory is accessed by a memory control circuit and stores temperature information indicating a temperature measured by a temperature sensor. A power supply control circuit supplies a first power supply voltage to the temperature sensor in response to a request for temperature measurement received via an antenna, and supplies a second power supply voltage to the nonvolatile memory and the memory control circuit after the temperature sensor measures the temperature. While the temperature sensor is measuring the temperature, the nonvolatile memory and the memory control circuit do not operate and thus do not generate heat. Therefore, the temperature sensor can accurately measure the temperature without being influenced from the heat generation caused by the operation of circuits in an RFID transponder.
