  • Patent number: 8786134
    Abstract: A wireless power transmitting system that transmits power from a power transmitting station to a power receiving station wirelessly includes the power receiving station. The power receiving station includes a unit receiving power from the power transmitting station, a unit obtaining a level of power received through the antenna, a unit obtaining a level of power consumed by the device operating while being supplied with received power and a unit transmitting the received power level and the power consuming level to the power transmitting station wirelessly. The power transmitting station includes a unit receiving the received power level and the power consuming level from the power receiving station wirelessly, a unit controlling the level of power transmitted through the transmitting antenna based on the difference between the received power level and the received power consuming level, and a unit transmitting power to the power receiving station wirelessly.

  • Patent number: 7882541
    Abstract: A mobile information processing device (200) obtains specific information of a user in response to an operation by the user, authenticates the user based on the specific information, establishes the first wireless communication mode, and then transmits authentication information to an information processing terminal. The information processing terminal (100) receives the authentication information from the mobile information processing device in the first wireless communication mode (A), verifies the received authentication information, generates an identification based on the resultant verification, transmits, in the first wireless communication mode, the identification to the mobile information processing device, then changes from the first wireless communication mode into the second wireless communication mode (B), and iteratively performs polling of the mobile information processing device.

  • Patent number: 7802112
    Abstract: An information processing apparatus includes a TPM, a key management module for managing a key database, a memory, and a file processing module for encrypting and decrypting a file. The TPM stores a first TPM key therein and encrypts a third TPM key. The key management module stores and manages the third TPM key in the database. When the information processing apparatus starts communicating with the tamper-proof device, the key management module receives, from the TPM, a parameter for generating a second TPM key, provides the received parameter to the tamper-proof device, receives from the tamper-proof device the second TPM key which has been encrypted using the first TPM key, and provides the TPM with the second TPM key and with the third TPM key which has been encrypted using the second TPM key.

  • Patent number: 5606632
    Abstract: A device comprises a look-up table translating unit, a region dividing unit and a reduced image generating unit to reduce the size of a color image using look-up tables and a reference look-up table. Each of the look-up and reference look-up tables has as many entries as there are the pixel values. The look-up table translating unit creates an entry check table. The entry check table is for translating the table entries of the look-up table into the those of the reference look-up table. The region dividing unit divides the original color image into a plurality of regions. The reduced image generating unit accesses the entry check table and the reference look-up table to selectively determine a representative pixel of the region based on the RGB values thereof to generate the reduced color images.
