  • Patent number: 8280532
    Abstract: Providing a remote control technique capable of realizing the achievement of constraints and the certain following of a target value even with a network in which delay, loss, distortion, or the like may occur. In a remote control system, an area setting unit of a client-side control unit sets at least two areas representative of a group of states of an target object, which changes over time by feedback control. A state-evaluation information sending unit sends, to the host-side control unit, state evaluation information obtained by evaluating the state of the target object based on the area set by the area setting unit. A target value setting unit of the host-side control unit sets a target value such that the state of the target object changes in the area set by the area setting units. Moreover, a target value updating unit updates the target value based on the state evaluation information received from the client-side control unit.

  • Patent number: 8184813
    Abstract: A scramble key generation unit generates scramble keys (individual encryption keys) which are different from one another and which are for encrypting and decrypting distributing data, by subjecting a predetermined initial encryption key at least once to a unidirectional reverse replacement and at least once to a trapdoor-equipped unidirectional replacement. A time key generation unit generates a time key (master encryption key) for regenerating the scramble keys, by subjecting any of the scramble keys generated by the scramble key generation unit at least once to the unidirectional reverse replacement. Thus, it is possible to efficiently and flexibly generate the individual encryption keys for encrypting and decrypting the distribution data, and master encryption key capable of regenerating some of the individual encryption keys.

  • Patent number: 8182774
    Abstract: A method to easily manufacture a nanosized EuSe crystal which has been conventionally difficult to be manufactured. Heating an Eu(III) complex whose general formula is represented by the following formula generates an EuSe crystal having a particle size corresponding to the heating condition. Alternatively, the mixture composed of Eu(III) complex, a counter cation, and a solvent may be heated. The particle size of the nanosized EuSe crystals can be manipulated by the heating condition, thus the absorption wavelength of the EuSe crystals can be easily controlled. In addition, it is easy to create a magnetooptic-responsive plastic using the high dispersibility of the EuSe crystals, thus it can be immediately applied to an optical isolator or other devices.

  • Patent number: 8107735
    Abstract: A face model providing portion provides an stored average face model to an estimation portion estimating an affine parameter for obtaining a head pose. An individual face model learning portion obtains a result of tracking feature points by the estimation portion and learns an individual face model. The individual face model learning portion terminates the learning when a free energy of the individual face model is over a free energy of the average face model, and switches a face model provided to the estimation portion from the average face model to the individual face model. While learning the individual face mode, an observation matrix is factorized using a reliability matrix showing reliability of each observation value forming the observation matrix with emphasis on the feature point having higher reliability.

  • Patent number: 8098428
    Abstract: Example embodiments relate to a circular dichroism fluorescent microscope having a confocal section. In the circular dichroism fluorescent microscope, a circularly polarizing/modulating section converts, into right and left circularly polarized lights, a light beam emitted from a light source. As such, the obtained right and left circularly polarized lights are focused on a sample so that the sample is irradiated with the right and left circularly polarized lights. Then, an optical lens focuses fluorescence emitted from the sample. Further, a wavelength selecting section transmits only fluorescence having a predetermined wavelength. Subsequently, the fluorescence having passed through the wavelength selecting section is detected.

  • Patent number: 8076307
    Abstract: Singar is identified as a novel molecule, whose expression is varied before and after the polarization of a nerve cell, and occurs in the tip of an elongating axon, called a growth cone, which is important for the formation or elongation of an axon. Singar is expressed specifically in the brain and the amount of Singar expression is largely increased in an individual during periods where the formation of axons is increased. It is observed that Singar is highly enriched in the growth cone at the tip of an axon. When the expression of Singar is inhibited in nerve cells in culture, the formation of multiple axons is induced. Thus, the inhibition of Singar can induce axon formation. Therefore, by inhibiting the expression or activity of Singar, it becomes possible to induce or promote the formation or elongation of an axon in a nerve cell.
