A photoelectric conversion element is realized in which the movement direction of electrons in the element changes according to the wavelength of light to be converted. A photoelectric conversion unit includes an active layer on which light to be converted is incident, an intermediate layer that is arranged on the active layer on a side opposite to the side on which the light to be converted is incident, and a reflection layer that is arranged so as to oppose the active layer with the intermediate layer interposed therebetween. The active layer includes a plasmonic material, which is a material in which plasmon resonance occurs due to a reciprocal action with the light to be converted. The intermediate layer has both a semiconductor property and transparency with respect to the light to be converted. The reflection layer has reflectivity with respect to the light to be converted.

The present invention relates to an authentication system, a small base station, and an authentication method which allow a server side to authenticate whether an installation position of a small base station is valid or not. In a packet to be sent as an authentication request from the femto base station, in-IC card information of an IC card inserted into the femto base stationis contained. A network terminating deviceconverts a local IP address described in a header of the packet to a global IP address, and sends it to a femto concentrator. The femto concentratorgenerates authentication information by associating the in-IC card information with the global IP address, and sends it to an authentication server. The authentication serverdetermines that the installation position of the femto base stationis valid if the in-IC card information and global IP address included in the authentication information have been associated with each other and registered in an authentication table. The present invention can be applied to a base station for a femtocell.

Authentication system, small base station, and authentication method

A communication system for solving a problem, in which secure communications security cannot be ensured in communications between a femtocell base station and UE, is provided. The communication system includes UE (User Equipment) and an HLR (Home Location Register) used in an IMS (IP Multimedia subsystem) network and a femtocell base station (Femto AP) that constructs a predetermined communication area. The femtocell base station exists between the UE and the HLR, acquires a concealment key corresponding to the UE from the HLR during authentication of the UE, and executes a concealment process to conceal the identity of the UE based on the concealment key.

Described herein are devices and methods for controlling inclination in a vehicle. In certain aspects, inclination of the vehicle can be controlled with an inclination control processing section that includes a first control value limiting processing section which calculates a moving amount of the centroid, calculates a maximum angular acceleration, and limits a variation of the control value for inclination control on the basis of the maximum angular acceleration.

A vehicle includes a vehicle body having a steering section and a main body section connected together; a steerable wheel which is rotatably mounted to the steering section and which steers the vehicle body; a non-steerable wheel which is rotatably mounted to the main body section; a steering apparatus for inputting a steering instruction information; an inclination actuator apparatus for inclining the steering section or the main body section in a turning direction; a steering actuator apparatus for varying a steering angle of the steerable wheel based on the steering instruction information inputted from the steering apparatus; and a control apparatus which controls the inclination actuator apparatus and the steering actuator apparatus. The control apparatus controls a center of gravity to move in a steering direction included in the steering instruction information at an initial steering stage so that an acceleration toward turning-locus inner side is generated.

The vehicle includes a vehicle body having a steering section and a drive section connected together; a steerable wheel which steers the vehicle body; a drive wheel which drives the vehicle body; an inclination actuator apparatus for inclining the steering section or the drive section in a turning direction; a plurality of sensors which detect lateral accelerations; yaw angular velocity detection means; vehicle speed detection means; and a control apparatus which controls the inclination of the vehicle body by controlling the inclination actuator apparatus. The control apparatus performs feedback control on the basis of the lateral accelerations, calculates a link angular velocity predicted value from the derivative value of the yaw angular velocity and the vehicle speed, and controls the inclination of the vehicle body by performing feedforward control while using the calculated link angular velocity predicted value.
