In the existing WLAN network, the authentication method using the pre-shared cipher key has low safety, and is not applicable for large scale deployment; while the authentication method based on 802.1x is very complex and needs to introduce EAP/RADIUS servers. The invention provides an authentication method and device in a converged wireless access network, wherein, the wireless access network and the UE all maintain a cipher key of a UE for accessing the first wireless access network, when the UE accessing the second wireless access network, the wireless access network and the UE implements the authentication based on the cipher key. In the invention, the UE key for accessing the first wireless access network, which has been obtained safely, is used in the authentication for the access of the UE in the second wireless access network. Compared to the traditional solution of the shared cipher key, the proposed solution ensures safety; and compared to the traditional 802.1x solution, it saves the operation of obtaining the cipher key via negotiating, and does not need to involve the network element such as key servers etc. |

Motor drive voltage control device and method for controlling motor drive voltage
To suppress a decline in the control accuracy of an applied voltage associated with an increase in quantum noise, and to increase the control accuracy of a motor speed. When generating a driving voltage signal supplied to a motor from a driving command signal, a motor-driving voltage control device reduces the gradation level and performs noise-shaping modulation before performing PWM modulation. Reducing the gradation level allows the degree of gradation of the driving voltage signal to be within the resolution range of the PWM modulation, and thus PWM modulation can be performed even when the driving voltage signal has a high frequency. Noise-shaping modulation reduces the level of quantum noise near the low frequency range by causing the quantum noise due to digitization, included in the driving voltage signal, to be biased toward the high frequency range side. Of modulation signals with the reduced-gradation level, the components near the high frequency band are cut, while the components near the low frequency range are used to suppress quantum noise and control the driving voltage applied to the motor with a high accuracy. |

Induction of force performed by the semiconductor laser diodes
Until now, the laser beam light is the main feature to be provided by semiconductor laser diodes. The highly ordered direct current of charge carriers injected into the active region of these electronic components above the lasing threshold can be used in innovative ways. This attribute is associated with a new theoretical concept when all particles which are part of macroscopic objects are widely coupled to each other via quantum entanglements—it can generate a distance force induction and a self-induction of force. Considering this, a force can be inducted in the external objects—thrusting them—and a force can be inducted in the own semiconductor laser diode structure for its self propulsion. |
