Intelligent Railway System for Preventing Accidents at Railway Passing Points and Damage to the Rail Track
First Claim
1. A method for managing trains on a railway track, said method including:
- analyzing track measurement data from a plurality of track sensors positioned along the railway track to collect the track measurement data, the track measurement data indicating physical loads exerted on the railway track at the track sensors; and
estimating, based on said analyzing of the track measurement data from the plurality of track sensors, at least one of;
at least one lower risk point of passing between a first train and at least one second train, the first train traveling in a first direction along the railway track, and the second train traveling in a second direction along the railway track opposite the first direction,at least one speed of the first train to arrive at the lower risk point of passing at the same time as the second train, andat least one speed of the second train to arrive at the lower risk point of passing at the same time as the first train.

Abstract
An embodiment of the invention provides a method for controlling access to content in a social networking website, wherein a connection is established between a first user and a second user on the social networking website. Content on the profile pages of the first user is categorized into a first content category and a second content category. The first content category includes content created before the connection between the first user and the second user was established. The second content category includes content created after the connection between the first user and the second user was established. Content in the first content category is also categorized into a first subcategory and at least one second subcategory. Access by the second user is restricted to the first content category. Specifically, the second user is prevented from viewing content in the first subcategory and permitted to view content in the second subcategory.
