20090201149 | MOBILITY TRACKING METHOD AND USER LOCATION TRACKING DEVICE - A user location tracking method allows a topology of a travel path taken by a user to be estimated without the use of location information such as GPS coordinates, so that a travel range of the user who only carries a small-sized terminal can be tracked at all times. The mobility tracking method is employed by a user location tracking device which uses radio waves sent from wireless devices distributed ubiquitously, the mobility tracking method including: detecting wireless device information identifying wireless devices out of the ubiquitously available wireless devices when the radio waves are received at a location where the user location tracking device is situated; storing the detected wireless device information as historical data; and estimating a topology, as the user location tracking device is moving, that shows a positional relation and a connection relation of a travel path taken by the user location tracking device, the estimation being performed on the basis that the location of the user location tracking device has deviated from a previously tracked path which has been traveled before by the user location tracking device and that the location of the user location tracking device has returned to the previously tracked path, using the stored historical data. | 08-13-2009 |
20100253623 | REMOTE CONTROL, IMAGING DEVICE, METHOD AND SYSTEM FOR THE SAME - A remote control, an imaging device, a method and a system for the same are provided to realize the functions such as channel selection of programs, character input, etc. The remote control comprises: an operation means having multiple keys, an ultrasonic and radio signal transmitting means for transmitting radio signals and ultrasonic signals while one of the said multiple keys is operated to map the position of the remote control into a cursor displayer on a screen, and a control means for controlling the said operation means and the said ultrasonic and radio signal transmitting means. | 10-07-2010 |

20130234512 | CURRENT CONTROL DEVICE, CURRENT CONTROL METHOD, AND CURRENT CONTROL SYSTEM - A current control device is a current control device which supplies current to a load device by controlling a current source including a first electric appliance and a voltage source including a second electric appliance. The current control device includes: an obtaining unit which obtains information indicating non-linear components included in load current that is current supplied to the load device; a determining unit which determines a first current that includes the non-linear components; and a notifying unit which notifies the current source of a command value for causing the current source to output the first current to cause the current source to output the first current. | 09-12-2013 |
20140236375 | ELECTRIC POWER CONDITIONING DEVICE AND METHOD FOR CONDITIONING ELECTRIC POWER - The electric power conditioning device, connected to an apparatus and an electric storage device in a house, comprises an electric power receiving section, a communication section and an operation section. The electric power receiving section, connected to a commercial power supply, acquires a total electric power consumption amount of the commercial power supply. The operation section makes comparison as to whether an integrated value obtained by integrating the total electric power consumption amount and an electric power consumption amount which is an amount of electric power expected to be consumed when the apparatus is operated exceeds a predetermined value. When the integrated value does not exceed, the operation section transmits a use permission signal to the apparatus via the communication section. When the integrated value exceeds, the electric power conditioning device transmits to the electric storage device a supply electric power inquiring signal via the communication section. | 08-21-2014 |
