  • Publication number: 20100079278
    Abstract: A power saving wireless fire alarm system has a master station and a plurality of battery-powered fire detecting cc terminals linked for wireless communication with each other. Upon detection of a fire occurrence at one of the fire detecting terminals, the fire detecting terminal transmit a fire detection message to a master station which in turn transmit a wake-up message to the other fire detecting terminals and thereafter a fire information message which starts a multiple synchronous communication between the master station and the fire detecting terminals. Each fire detecting terminal has a power controller which selects an intermittent reception mode of activating its own receiver only intermittently until receiving the wake-up message or information indicative of the fire occurrence, and select a constant operation mode thereafter to make the fire detecting terminals be ready for the multiple synchronous communication commenced by the fire information message from the master station.

  • Publication number: 20100046596
    Abstract: A radio communication system minimizes power consumption against noises. The system includes a first radio terminal (10A) with a first transmitter (40A) for transmitting a first data indicative of a specific event, and a second radio terminal (40A) with a battery (14B) and a receiver (20B). The first radio terminal (10A) includes a first bit interpolator (32A) which inserts a check bit pattern of “01010101” at a predetermined cycle into one frame of the first data. The second radio terminal (10B) has a second power controller (60B) which intermittently activates the second receiver (20B) at predetermined intervals in order to receive the bit-interpolated data from the first transmitter.
