Abstract: An inference apparatus provides target data to multiple inference models to cause the inference models each derived from local learning data obtained in a different environment to perform predetermined inference to obtain an inference result from each of the inference models. The inference apparatus determines the value of each combining parameter using environment data, weights the inference result from each of the inference models using the determined value of each combining parameter, and combines the weighted inference result from each inference model together to generate an inference result in a target environment.

Abstract: The present invention relates to the reduction of handoff delays for mobile telematics applications. In particular, the present invention provides a method employing GPS technology to define IP addresses in a mobile environment in order to reduce delays and transient data loss caused by handoff from one network to another.

Abstract: A method of tailoring data streams transmitted to networked user devices is disclosed in which environment information associated with each device is stored at an agent located on those devices. This environment information may include information related to the hardware, interface and application capabilities of the particular device. In another embodiment, this environment information is transmitted and stored at an agent at a local network gateway. And in another embodiment, the environment information is then stored at a mirror agent located in a backbone network of a service provider. By referring to this environment information, a service provider can tailor the transmission of data streams, such as multimedia streams, to a device based on the capabilities of the device and the associated network.

Abstract: A positioning system is disclosed in which a rate of change .DELTA..DELTA.f in a Doppler shift .DELTA.f of the radio wave transmitted from a GPS satellite is detected in order to determine whether or not an extraordinary radio wave as caused by a multi-path or the like is being received, and a GPS satellite from which an extraordinary radio wave is received is excluded from a group of GPS satellites which are utilized in a positioning calculation. A difference .DELTA.f between a signal frequency f0 transmitted from a GPS satellite and a signal frequency fR receiver is calculated, and a rate of change .DELTA..DELTA.f in the difference .DELTA.f is also calculated. The position of a receiver is calculated on the basis of information transmitted from a plurality of GPS satellites for which the rate of change .DELTA..DELTA.f is equal to or less than a first threshold value, or .DELTA..DELTA.f.ltoreq.

Abstract: A mobile object positioning system includes a GPS signal receiver for receiving positioning radio signals from a plurality of satellites, calculating a present location of a mobile object in accordance with the positioning radio signal and outputting present location data at each of a plurality of calculating times. An electronic controller is provided for updating the present location data at each calculating time, storing the present location data, estimating an error of the present location data in accordance with the positioning radio signals and outputting error data at each estimating time. A vehicle velocity sensor is disposed on the mobile object for detecting the velocity of the moving mobile object and outputting a mobile velocity signal.
