  • Patent number: 7869807
    Abstract: In one wireless device, when wishing to participate in a communications network, an ID generator in an ID manager uses a hash function on the address of the device and time to generate a device identification identifying the one device, and registers the identification on a list storage. In the one wireless device, a list updater stores an identification of another device from a beacon signal into the list storage in association with the address of the other device. When a conflict determiner detects a conflict of device identifications, an ID searcher searches the list storage for an unused identification having a relationship with the conflicting identification according to a relation in magnitude between the addresses of the one and other devices. An ID updater updates the identification of the device in the list storage to the unused identification thus searched for as a new identification.

  • Publication number: 20100219051
    Abstract: A turn signal device for a vehicle for activating a turn signal in accordance with operation of an operation lever. The turn signal device includes a turning state detection unit, which detects a turning state of the vehicle. The turning state detection unit monitors a temporal change in the turning state of the vehicle after the turn signal is activated. The turning state detection unit deactivates the turning signal when detecting that the vehicle first turns in an activation direction of the turn signal, then turns in a direction opposite to the activation direction, and afterward turns again in the activation direction.
