摘要:
A wireless base station that has a plurality of antennas and repeatedly executes a cycle where reception and transmission are performed to communicate with a plurality of mobile stations at a same time using an adaptive array method. During reception in a cycle, the wireless base station calculates first weight vectors for forming directivity patterns and uses the first weight vectors during transmission to form the same directivity patterns as during reception in a same cycle. When a reception error occurs during reception of a signal from an arbitrary mobile station, the wireless base station calculates, from current response vectors of other mobile stations, a second weight vector that is used in place of the first weight vector when forming a directivity pattern for the arbitrary mobile station during transmission in a same cycle as the reception error. This directivity pattern has null directivity for the other mobile stations.

A parameter estimation device for estimating parameters relating to input and output of a control object by using a neural network, including control domain division means for selecting at least one parameter having strong correlation with non-linearity amongst input-output characteristics of the control object, as a parameter of a premise part of fuzzy operation, and dividing a control domain of the control object into a plurality of small domains by fuzzy estimation based on the parameter of the premise part; and estimation means for estimating dynamic behavior of the control object by using, as a consequent part of the fuzzy operation, a neural network which receives a parameter indicating the operation state of each of the small domain into which the control domain is divided, so that the output from the neural network can be checked in advance.

A vehicle navigation system and storage medium for determining an estimated position of a vehicle. The system and storage medium comprises at least an input unit, a present position detection unit, a storage unit, a central processing unit, an information transmission/reception unit and an output unit. Information concerning route guidance is input, as is present position detected information, and stored such that calculation of an estimated position of a vehicle may be generated based on a variety of conditions such as vehicle speed history, elevation angle of a satellite position relative to the vehicle, and penalty values attributed to the types of roads traveled.
摘要:
An output parameter estimation apparatus for estimating an output parameter from an input data set that is composed of a plurality of input parameters and that is obtained whenever sampling time series input data. In this output parameter estimation apparatus, a fuzzy inference rule is used to calculate a fitness degree of the input data set in one of a plurality of fields included in a space that is formed using at least one input parameter. According to the calculated fitness degree, introduction routes through which the input data set is to be inputted into a neural network are selected. The neural network is set in a connection condition corresponding to the field to which the input data set belongs, the connection condition having been determined in advance as a result of learning process. With this connection condition, the neural network estimates the output parameter from the input data set inputted through the selected introduction routes.
摘要:
A second harmonic generation (SHG) device is used for conversion of wavelength. The direction of polarization of light beams is suitably rotated by a direction-of-polarization rotating unit, for example by 45.degree., and thereafter these light beams are guided into the SHG device. This can minimize attenuation of intensity of light beam due to conversion of wavelength. Hence, using this direction-of-polarization rotating unit in the apparatus for measuring the medium, the intensity of light being incident upon the photodetector can be increased, whereby the refractive index of the medium can be measured more accurately than by the conventional apparatus.

Provided is an in-vehicle charger capable of reliably obtaining charging control parameters prior to charging and capable of safe charging. In this charger, a charging unit (105) charges a battery (111) in accordance with the charging control parameters. A storage unit (103) stores a table in which a plurality of areas on a map and the charging control parameters are made to correspond to each other. A position information receiving unit (101) obtains position indicating the current position of a vehicle (250). A control unit (104) refers to the table on the basis of the position information and sets the charging control parameters made to correspond to an area including the current position when a charging cable (107) is not connected.
摘要:
A three-dimensional model data producing processing apparatus produces three-dimensional model data using design data (CAD data) of an object to be recognized. The three-dimensional model data producing processing includes processing conversion processing, edit processing, and teaching processing. The conversion processing and the edit processing are performed to the design data on a computer. The teaching processing is performed in a practical environment. It is not necessary to image a workpiece model in the three-dimensional model data producing processing.
