  • Publication number: 20120161692
    Abstract: In a charging control system, electrically-driven vehicles whose charging levels are lower than such a charging level required to drive these electrically-driven vehicles over a necessary minimum drivable distance are charged with a priority, and such an electrically-driven vehicle whose charging level quickly reaches the above-explained charging level among these electrically-driven vehicles is charged with a top priority. Also, in the charging control system, an order for dynamically charging vehicle-purpose batteries is rearranged by monitoring a change in charging environments, for instance, an electrically-driven vehicle is newly coupled to a charger in a half way; a commonly available electric power amount is increased by solar power generation etc.; and a supplyable electric power amount (W) is lowered due to utilization of electricity by a subject other than electrically-driven vehicles.

  • Patent number: 7873767
    Abstract: A wireless IC memory, for improving the security thereof, for achieving protection of business information and privacy, comprises an RFID tag 100, wherein it is possible to setup “readout disenabling (ReadLock)” condition to the UII code bank for storing ID data of the RFID tag 100, with a predetermined protocol from an external communication apparatus, within the RFID tag 100. Setup of “readout disenabling (ReadLock)” condition is stored on a readout enabling/disenabling condition memory portion 105 within the RFID tag 100. In case where the “readout disenabling (ReadLock)” condition is set up in the UII code bank, a protocol process controller portion 103 of the RFID tag 100, not responding the UII code, normally, but answers a fake UII code or an error code, or gives no answer, to a request or command of readout of the UII data from the external communication apparatus.
