  • Publication number: 20220253223
    Abstract: In an approach to adaptive tape calibration criteria based on the number of dead tracks, the number of rewrite occurrences for each dead track on a tape drive is determined. Responsive to detecting that a head is in a dead track state, the number of dead tracks is stored on the tape drive. A calibration threshold is determined, where the calibration threshold includes the number of dead track rewrites and the calibration reference value for a specific tape drive type. Responsive to the number of rewrite occurrences exceeding the calibration threshold while writing a data set, a calibration of the tape drive.

  • Publication number: 20220229120
    Abstract: A used secondary battery module management system server manages a manufacture of a battery assembly. The server stores, in a memory, a correspondence relationship of each of secondary battery modules among identification information, ranks, and status information. The server extracts an available rank from the ranks in response to a rebuilding request for the battery assembly. The available rank is a rank in which the number of the secondary battery modules having the status information indicating that the secondary battery modules are available is equal to or larger than the number of the secondary battery modules required to constitute the battery assembly. The server receives, from an external terminal, the identification information on each of selection secondary battery modules having an identical rank.

  • Patent number: 11370434
    Abstract: An inter-vehicle communication and driving assistance device performs wireless communication with other vehicles, and includes an inter-vehicle communication unit including a reception level detection unit, a position information reception unit, and an arithmetic processing unit. The arithmetic processing unit calculates inter-vehicle distances to other vehicles using latitude and longitude information of the other vehicles and the own vehicle, receives a position error radius, and acquires a reception level from the other vehicles. When a difference between the inter-vehicle distances is smaller than position error radius, a vehicle with a larger reception level is determined as a vehicle closer to the own vehicle. When the difference between the inter-vehicle distances is larger than the position error radius, a vehicle with a smaller inter-vehicle distance is determined as a vehicle closer to the own vehicle, and a distance to a leading vehicle is calculated.

  • Patent number: 10937453
    Abstract: A methodology that enables, for example, tape drive operation at lower SNR and/or reduced rewrite area uses a first threshold T and a second threshold r for a rewrite condition. Codeword interleaves (CWIs) in a data set are written onto a plurality of simultaneously-written parallel tracks of a magnetic recording medium, read back and error correction decoded. A determination is made as to whether at least one of the C1 or C1? codewords in each decoded CWI contains more byte errors than the second threshold r of the rewrite condition. A number of CWIs in a rewrite buffer are according to the following criteria: bi?=bi?T when bi is greater than the first threshold T, and bi?=0 when bi is less than or equal to the first threshold T.
