Abstract: A system and method for implementing an iterative query mechanism to facilitate query-time sessionization and analysis of data is disclosed. At least, the method includes determining a table of independent events, determining a query, the query including a parameter specifying a size limit on a sample of sessions, executing the query against the table of independent events, at the time of query execution, processing the table of independent events to reconstruct the sample of sessions approaching the size limit, and at the time of query execution, analyzing the sample of reconstructed sessions to generate a result.

Abstract: A mileage prediction and optimization system (FIG. 1) is disclosed for optimizing the mileage of a vehicle. The mileage prediction and optimization system comprises a prediction and optimization module (300) adapted to determine variation in mileage of the vehicle at least based on the current fuel volume, current speed, current fuel density, the current tire air pressure, the current tire air temperature, current fetched values from an ECU module (700) and the pre-defined mileage data of the vehicle. Further, the prediction and optimization module (300) is adapted to optimize the mileage of the vehicle by reducing variation of fuel density, reducing variation of tire air pressure and informing optimal gear-speed combinations to a user regardless of whether the vehicle is stationary or in motion.

Abstract: A privacy protection system enables a user to prevent unwanted and access to data collected by the camera or microphone of a cellular device. The camera is obstructed by a member in such a way as to allow light to reach the camera in an unintelligible state. The microphone is blocked by a knob to prevent sound from reaching the microphone. The member and knob are positioned by way of a case.
