Abstract: A digital train brake testing and train preparation assistant uses a system, method, and computer program for determining a component parameter of a train. The system may include sensor nodes mounted to a respective part of the train, wherein the sensor nodes form a sensor network on a rail car, wherein railcars form a wireless mesh network, and wherein each of the sensor nodes is configured to collect data of the component of the respective part of the train and to publish the collected data into the wireless mesh network. The system may further include a server system configured to receive the published data of the wireless mesh network and to determine the component parameter of the train based on the received data. Furthermore, a user device for displaying a component parameter determined by a system, method, and computer program for determining a component parameter of a train is provided.

Abstract: A system and method for automatic generation of a list of units in a train comprising multiple units use a plurality of sensors, wherein each of the plurality of sensors is configured to be mounted to a respective unit of the train and each of the plurality of sensors is configured to detect a parameter of the respective unit of the train to which it is mounted that is suitable to provide an information about the position of the unit with respect to another unit in the train. Further, the system includes a control device configured to receive the detected parameters from the plurality of sensors and to process the detected parameters for generation of the list of units.

Abstract: A deployment infrastructure for sharing usage metrics with customers is described. An example method includes transforming a usage view file into an anonymous block build file. The usage view file corresponds to a view of customer usage data. The method includes embedding the anonymous block build file into a task, and executing the task to produce a share object that is based on the anonymous block build file. The method includes deploying the share object to a customer account, which enables the customer account to access the view of the customer usage data.

Abstract: A method of content delivery in a content delivery network (CDN), where the CDN is deployed, operated and managed by a content delivery network service provider (CDNSP). The CDN comprises a set of content servers and a domain name system (DNS). For a given content provider, a determination is first made whether the content provider has “cold content” delivery requirements by evaluating one or more factors that include: total content size, size of content objects expected to be served, uniqueness of content, total number of content objects, and a percentage of the total content size that is expected to account for a given percentage of traffic. Upon a determination that the content provider has cold content delivery requirements, a subset of the CDN content servers are configured to implement a set of one or handling rules for managing delivery of the cold content from the CDN content servers.

Abstract: A system for parallax correction includes a first lens having a first pin extending radially therefrom and a second lens positioned parallel to the first lens. A moving platform has a first slot for accepting the first pin therein. The first slot is angled relative to the lenses to correct for parallax between the first and second lenses. The system can include an actuator for extending and retracting the moving platform towards and away from an object to focus on the object.

Abstract: A system for parallax correction includes a rotatable focus adjuster having a longitudinal axis. A lens retainer is engaged with the focus adjuster.

Abstract: A multi-tiered approach to combating reverse engineering of electronics is disclosed herein. The encapsulant utilized with the optical sensor may be selected based on being substantially being opaque to X-ray inspection. In this way, visible public inspection to gain competitive intelligence may be reduced and operation of the electronics may remain unaffected. Additionally, a thin filament of wire embedded just below the surface of the encapsulant could be used as an electronic tripwire in response to being severed and/or dissolved by the reverse engineering strong solvents and acids.
