DATA PROCESSING DEVICE, DATA PROCESSING METHOD, AND COMPUTER READABLE MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18535101 titled 'DATA PROCESSING DEVICE, DATA PROCESSING METHOD, AND COMPUTER READABLE MEDIUM

Simplified Explanation

The patent application describes a system for estimating the position of a disturbance wave generation source in a train by analyzing reception power values during wave generation periods.

• The system estimates the purely-lateral position of the disturbance wave generation source with respect to the train.
• It extracts features from measured reception power values during disturbance wave generation periods.
• Candidate distances between the estimated position and the generation source are extracted from learning data.
• The system matches features of estimated reception power values with measured values to determine the candidate distance.
• The position of the generation source is estimated based on the extracted candidate distance.

Potential Applications

This technology could be applied in:

• Train communication systems
• Signal interference detection systems
• Location-based services in trains

Problems Solved

This technology solves the following problems:

• Accurate estimation of disturbance wave generation source position
• Improved communication reliability in trains
• Enhanced train safety measures

Benefits

The benefits of this technology include:

• Increased accuracy in estimating source positions
• Enhanced communication system performance
• Improved passenger safety and comfort in trains

Potential Commercial Applications

Potential commercial applications of this technology include:

• Integration into train communication systems
• Licensing to train manufacturers
• Implementation in railway infrastructure projects

Possible Prior Art

One possible prior art for this technology could be:

• Existing train communication systems that do not account for disturbance wave source position estimation.

How does the system handle multiple disturbance wave sources in close proximity?

The system may struggle to accurately estimate the position of multiple disturbance wave sources if they are too close together. Further research may be needed to address this issue.

What is the impact of environmental factors on the accuracy of position estimation?

Environmental factors such as weather conditions or terrain may affect the accuracy of position estimation in the system. Additional studies could explore the system's performance under various environmental conditions.

Original Abstract Submitted

A purely-lateral position estimation unit () estimates as an estimated purely-lateral position, when a disturbance wave to disturb communication performed in a train is generated while the train is traveling, a position existing in a purely-lateral direction with respect to a position of a generation source of the disturbance wave. A feature extraction unit () extracts a feature of a measured reception power value being a reception power value measured in the train during a disturbance wave generation period wherein the disturbance wave has been generated. A candidate distance extraction unit () extracts, from learning data indicating a plurality of candidate distances being candidates of a distance between the position of the generation source of the disturbance wave and the estimated purely-lateral position, and indicating for each candidate distance, a feature of an estimated reception power value estimated to be measured in the train when the distance between the position of the generation source of the disturbance wave and the estimated purely-lateral position is the candidate distance, a candidate distance for which the feature of the estimated reception power value matches the feature of the measured reception power value, as an extracted candidate distance. A generation source position estimation unit () estimates a position being distant from the estimated purely-lateral position by the extracted candidate distance, as the position of the generation source of the disturbance wave.
