Abstract: A method, system and computer program product for shielding an operator of a vehicle from light, including determining a position of a light source based on the location of the vehicle and the current date and time. A line of sight between the light source and the eyes of the operator is determined, where the line of sight goes through a windshield of the vehicle that includes a plurality of pixels. One or more pixels in the line of sight are identified; and, one or more physical properties of the pixel(s) in the line of sight are modified.

Abstract: Methods, computing systems and computer program products implement embodiments of the present invention that include arranging multiple storage devices as a RAID array and receiving, from a given storage device storing a dataset, a number of error messages exceeding a threshold. A mirrored subset of the dataset is retrieved from the given device, and a calculated subset of the dataset is retrieved from remaining devices in the RAID array. In a first embodiment, the mirrored subset is created first, and the calculated subset includes a relative complement of the mirrored subset with respect to the dataset. In a second embodiment, the calculated subset is created first, and the mirrored subset includes a relative complement of the calculated subset with respect to the dataset. The mirrored and the calculated datasets are stored to an additional storage device, and the given device is replaced with the additional device in the RAID array.

Abstract: In a tape recording apparatus having a write head and a read head, a data block is stored by writing to a tape via the write head. The tape moves past the write head in a predetermined direction and writes a first data block responsive to transmitting the first data block from the computer system. The read head then reads the written data block from the tape. For reading, the tape moves past the read head in the same, predetermined direction as the writing, and the reading of the first data block occurs without reversing the tape movement after the writing of the first data block. Portions of the transmitted and read data blocks are compared and a corruption indication is sent responsive to the comparing.

Abstract: The invention aims to improve a floor for rail vehicles in such a way that an even, level, reference plane for constructing the floor is obtained by a simple tolerance compensation of the deviations in the longitudinal direction, transverse direction and height of the shell assembly. Said compensation is embodied as an easy-to-assemble positive-fit connection between the floor plate and the body-shell floor plate. This is achieved by a retaining profile which is configured as a profile with a recess for accommodating a connecting element and provided with at least one blind opening. An elastic spacer, comprising a plug-in extension to compensate for the existing differences in level between the floor plate and the floor-profile plate, is inserted into the blind opening under pressure, forming a positive-fit. The positive-fit between the blind opening and the plug-in extension is perpendicular in relation to the positive-fit between the profile batten and the retaining profile.
