  • Publication number: 20160029149
    Abstract: [PROBLEMS] To provide a low-power-consumption short-range wireless communication system enabling wireless communication devices to perform ad hoc communication without necessitating it to have a server (central device). [MEANS FOR SOLVING PROBLEMS] The inventors have focused on transmission to detect connection destination in the proximity which is performed before establishing connection in low-power-consumption short-range wireless communication systems, e.g. advertisement packets (or scan packets) in the Bluetooth Low Energy communication system. The inventors have designed a mechanism in which various information including an identifier unique to a device is transmitted in attachment to the above packets thereby enabling the devices to perform a high-speed and ad-hoc communication.

  • Publication number: 20160003876
    Abstract: An EoD system for personal living activities. A current electric power value is received from a smart tap, a use state q of an appliance is estimated from the current electric power value, change of the use state is detected as an event when the use state is different from a use state of a previous time, and the type of the event and an occurrence time are stored in a memory. Following that, a first weight of the living activity by the type of the event is calculated based on an appliance function model and an elapsed time from the event occurrence time, and a second weight to each living activity corresponding to the current use state of the appliance is acquired from an appliance function model. Based on the product that is a multiplication of the first weight and the second weight, a sum of the products is calculated for each appliance, and a living activity label, in which the sum of the product values of each appliance becomes a maximum value, is estimated as a living activity label of a time.
