Abstract: Methods for making fire retardant material including fire retardant cellulosic insulation are described. The methods include arrangements for partitioning fibers derived from fiber feedstocks and adding at least a portion of fibers of one or more feedstocks and a fire retardancy chemical compound to a mixer prior to fiber drying. The fibers may be disentangled and/or partitioned prior to mixing with the fire retardancy chemical compound. The fibers may be partially dewatered prior to the drying or other steps of the methods. The feedstock may include old newsprint (ONP), old corrugated containers (OCC), and/or other cellulose-based materials. The method further includes retaining the fibers feedstock and the chemical compound together for enough time to ensure adherence and impregnation of enough of the chemical to and in the fibers after the drying process. Fibers may be partitioned and disentangled prior to, during, and/or after treatment with the fire retardancy compound.

Abstract: A method for checking a functional capability of a distance sensor of a vehicle includes continuously receiving sensor data from the distance sensor, wherein the sensor data describe a sensor signal emitted by the distance sensor and reflected on at least one object in an environment of the vehicle; continuously determining distance values, which describe a distance between the distance sensor and the at least one object, on the basis of the sensor data; storing the distance values for a predetermined period of time; determining a current range of the distance sensor on the basis of the stored distance values; comparing the current range with a predetermined maximum range of the distance sensor; and checking the functional capability of the distance sensor on the basis of the comparison.

Abstract: A test device for testing a detection device includes a reflection element with reflective surface where the reflective surface is a radar reflective surface and/or an ultrasound reflective surface. The reflection element is movable by a drive device periodically back and forth in a translational movement along a movement axis with respect to a housing of the test device. A movement of the reflection element produces a relative speed unequal to zero of the test device with respect to the detection device.

Abstract: The invention relates to a high-frequency-transparent component comprising: a main body (2) and a coating (3) consisting of metal-doped Al2O3 sputtered thereon, and to a method for producing said component.

Abstract: A method and system may reconstruct data in a smart storage array where upon detection of data inconsistency, an application of the system is notified and affected data strips are rebuilt. When an initiator detects stripe corruption, the initiator may report the strip corruption to storage. The storage may lock the strip for I/O operations. Initiators may determine recovery scenarios for rebuilding the data strips and send the scenarios to storage. At storage, initiator replies may be collected, and a rebuild option with the highest votes may be automatically determined for a reconstruction operation. Once the reconstruction operation is completed, the rebuilt stripe may be unlocked and data operations may recommence.

Abstract: A mechanism is provided for dispersed location-based data storage. A request is received to write a data file to a referrer memory region in a set of memory regions. For each data chunk of the data file, responsive to a comparison of a hash value for the data chunk to other hash values for other stored data chunks referenced in the referrer memory region indicating that the data chunk fails to exist in the referrer memory region, responsive to the data chunk existing in another memory region in the set of memory regions, responsive to the memory region failing to be one of the predetermined number N of owner memory regions associated with the referrer memory region, and responsive to the predetermined number N of owner memory regions failing to have been met, a reference to the data chunk is stored in the referrer memory region.

Abstract: Systems and methods of producing a frozen food product include dosing ingredients with a liquefied gas while mixing the ingredients using self-cleaning interlocking beaters. The beaters are optionally also disposed to clean a container in which the ingredients are frozen. The rate and amount of cooling is controlled by measuring the quantity of liquid nitrogen, measuring viscosity of the frozen food product, measuring temperature, and/or the like.

Abstract: A computer-implemented method according to one embodiment includes receiving data, storing chunks of the data in fixed size blocks in physical storage, and deduplicating a copy of the data. The storing includes splitting some of the data chunks into portions for filling the fixed size blocks. Metadata is stored with the data chunks for chaining the associated portions of the split data chunks together. The deduplicating including creating a pointer to a first of the data chunks. A computer program product for utilizing free space in physical storage, according to another embodiment includes a computer readable storage medium having program instructions embodied therewith. The computer readable storage medium is not a transitory signal per se. The program instructions are readable and/or executable by a computer to cause the computer to perform the foregoing method.

Abstract: A computer-implemented method according to one embodiment includes determining resource usage of at least a first module in a grid storage system having multiple modules and approximately equal resource usage across the multiple modules of the grid storage system. The computer-implemented method further includes determining a garbage collection cost in the grid storage system by stopping garbage collection in a second of the modules of the grid storage system, determining a resource usage in the second module upon stopping the garbage collection, and comparing the resource usage in the second module to the resource usage of the at least the first module. The method further includes adjusting an amount of garbage collection based on both the garbage collection cost and the resource usage.
