    摘要: In particular, even if sensors have their respective different timer precisions, the number of occasions when the sensors wait for data can be minimized, thereby reducing the output consumptions on the sensor sides. A coordinator (3) allocates, based on information previously received from sensors (2), the sensors to respective slots, which constitute a super-frame, in a time sequence order and then notifies, to the sensors (2), the respective slots to which the sensors are allocated. When each of the sensors (2) transmits data to the coordinator (3), the sensor makes a synchronization request at the timing of the notified slot without receiving any beacons from the coordinator.

    摘要: A decentralized key management scheme that implements key management of a tree structure comprised of only group members without using a key management server is proposed, and communication method and system that can contribute to secure group communications is provided. Each member constituting a group updates tree structure data of the entire group when a new member joins, respectively 70, and selects a captain in each subtree 71. Rather than the key management server, the captain generates a new key and shares it with other captains or the joining member 72, and distributes the new key to the members of the subtree 73, thereby enabling all the group members to update to the new key. A captain is also selected when a member leaves, and sharing and distribution of a new key by the captain is performed.

    摘要: An identification-information extracting unit extracts first identification information of a location registration area of a wireless communication system. A storage unit stores correspondence information concerning a relationship between the first identification information and second identification information of a location registration area managed by a communication network system. A location-registration requesting unit transmits location-registration request information for requesting a location registering device to perform a new location registration when the second identification information is updated by a movement of a mobile terminal.

    摘要: An M-sequence generator includes EXCLUSIVE-OR gates feeding back pieces of bit data from m number of series registers to the registers in response to a clock. A period of a cyclic group {(α1k), (α2k), (α3k), . . . } falls within a maximum period (2m-1), the group being produced as an element (αk) obtained by raising a root α of a polynomial to a specified power value k (k≧2), which have the terms in polynomials of a Galois field GF(2m). In a multiplying unit including the gates, pieces of bit data is fed into one end of the multiplying unit in response to the clock while the element (αk) is fed into the other end. The multiplying unit performs Galois field multiplication between each piece of bit data and the element (αk), the gate supplies the multiplication result as feedback bit data to the respective registers.

    摘要: A control system controls a multiphase rotating machine by a 120° energization process and a PWM process. In the 120° energization process, respective ones of switching elements of a high side arm and switching elements of a low side arm of a power conversion circuit are turned on. In the PWM process, the switching elements of the power conversion circuit turn on/off so that two phases that are connected to the switching elements that are in the on-state are alternately rendered conductive to the high potential side input terminal and the low potential side input terminal of the power conversion circuit.

    摘要: A analog/digital modulation type discrimination circuit 1 discriminates whether a reception signal is an analog modulation type, a linear modulation type or a non-linear modulation type by digital modulation type. In case where the reception signal is discriminated to be the analog modulation type, an analog modulation type discrimination circuit 2 discriminates whether it is an AM signal or an FM signal among the analog modulation type. In case where the reception signal is discriminated to be the linear modulation type by digital modulation type, a linear modulation type discrimination circuit 3 discriminates whether it is a BPSK signal, a QPSK signal, a π/4-shift QPSK signal, an 8-PSK signal, an M-ary PSK signal of multi-level exceeding 8-levels, a 16 QAM signal or a n M-ary QAM signal of multi-level exceeding 16-levels among the linear modulation type by digital modulation type. In case where the reception signal is discriminated to be the non-linear modulation type by the digital modulation type a non-linear modulation type discrimination circuit 4 discriminates whether it is an M-ary FSK signal, a 2-FSK signal, an MSK signal or a GMSK signal among the non-linear modulation type by the digital modulation type.
