Patent number: 7631215Abstract: A personal digital assistant comprises a loss detector to detect a lost state and a value information retainer for retaining a value assessment index, which are numerical values indicating data values. When a lost state is detected by the loss detector, a data recovery sequence is determined based on the data values and data is transmitted to another terminal. In determining the recovery sequence, electrical energy required for data transmission is calculated using a power consumption table and the remaining battery power level measured by a remaining battery power level meter is referenced.Type: GrantFiled: December 13, 2005Date of Patent: December 8, 2009Assignee: Casio Hitachi Mobile Communications Co., Ltd.Inventors: Kiyoshi Ikehara, Kenji Kitagawa, Yoshiaki Morimoto

Patent number: 7375615Abstract: An apparatus is disclosed for reducing the vexatious complication of personal authentication when using an information technology device or a card. A combination of RFID tags worn by a user is stored when personal authentication is carried out. The RFID tags are detected again In a situation where personal authentication is required. The continuous use of the previous personal authentication is permitted depending on the extent of coincidence between pieces of RFID information thus detected and the combination of stored RFID information, so that further authentication operations can be omitted. In addition, reference is made to a past archive when an RFID list is created. A weighted coefficient is then calculated based on the put-on frequency (put-on archive) in terms of a user's single article or a combination of such articles. The utilization of the weighted coefficient provides personal authentication with a high level of reliability.Type: GrantFiled: June 8, 2005Date of Patent: May 20, 2008Assignee: Hitachi, Ltd.Inventors: Kenji Kitagawa, Motoaki Satoyama

Publication number: 20060117308Abstract: A data processing apparatus (1) can implement the execution of a virtual machine instruction based on an execution routine specified by the native instruction of a CPU (2) and has an address converting unit (3) capable of sequentially converting an address output from the CPU into the address of the native instruction by utilizing the address of a prepared execution routine in response to the application of a prescribed condition. The address converting unit reads a virtual machine instruction to be executed next and prepares the address of an execution routine corresponding thereto in parallel with the execution of the execution routine by the CPU based on the address of the native instruction which is sequentially converted. Accordingly, it is possible to reduce the overhead of a processing of loading the virtual machine instruction and a processing of executing an instruction in accordance with the execution routine which is caused by an address calculation processing based on the load processing.Type: ApplicationFiled: August 30, 2002Publication date: June 1, 2006Inventors: Kazuya Hirayanagi, Kenji Kitagawa, Kesami Hagiwara, Tkanori Aoki, Naoki Mitsuishi
