Publication number: 20240119103Abstract: A technology for the optimized capturing of resource file content for resources referred in recorded user interaction sequences is disclosed. Individual resource files are typically referred in multiple recorded resources, therefore it is desired to capture those resources only once and reuse them for all recorded session capturing them. As user interaction sequences are executed and captured in independently operating web-browsers, a direct coordination between recording web-browsers to avoid multiple captures of the same resource is not possible. Data about the global resource capturing and demand situation is generated on a monitoring server that receives all session recording data and transferred to session recording browsers in form of lists identifying resources that are referred in sessions but are still unresolved and should therefore be captured, and for resources that should not captured, because they are already available and capturing them again should be avoided.Type: ApplicationFiled: October 18, 2023Publication date: April 11, 2024Applicant: Dynatrace LLCInventors: Bernhard LACKNER, Jordi MASRAMON, Otmar ERTL

Publication number: 20240106903Abstract: A technology is disclosed for the browser side capturing of user interaction session data and replay of the session data for a high-fidelity reconstruction of the experience the user perceived. In addition to capturing central structuring and markup documents and browser side updates thereof, additional resource documents that are loaded and used by the browser to render the central documents are captured and added to the session recording data. Identification information is created for resource documents, based on the content of those documents, which allows the capturing system to distinguish different versions of those content documents that share the same name but have different content. The captured session data contains data to identify the correct versions of resource documents during replay. Various measures to reduce the amount of transferred resource content data are applied, that consider already captured resource document versions or the usage frequency of a monitored application.Type: ApplicationFiled: December 1, 2023Publication date: March 28, 2024Applicant: Dynatrace LLCInventors: Bernhard LACKNER, Jordi MASRAMON, Otmar ERTL, Alfonso CORRETTI

Patent number: 7446488Abstract: A vehicle lighting system receives power from a power supply and includes a lighting control module, a lamp, and a ballast having a bias control circuit. The lighting control module provides a remote enable signal to the ballast in response to an input. The bias control circuit of the ballast receives a supply voltage from a power supply and the remote enable signal and selectively energizes a bias regulator circuit of the ballast as a function of the remote enable signal. When the bias regulator circuit is energized, a controller of the ballast operates the ballast to provide power from the power supply to the lamp.Type: GrantFiled: August 29, 2007Date of Patent: November 4, 2008Assignee: Osram SylvaniaInventors: John Cross, Walter Batz, Torsten Kuske, Bernhard Ertl
