  • Patent number: 10651945
    Abstract: An encoding device includes an encoding unit, DA converters, light sources, intensity modulators, and wavelength multiplexers. The encoding unit adds (NM/2) to an encoded signal having a negative minimum value in a range of the encoded signal among encoded signals of N channels of (NM+1) values obtained by calculating an inner product of a Hadamard matrix of N rows and N columns and a matrix having elements of N intensity signals of (M+1) values. The DA converters of the channels convert the encoded signals of the channels from digital signals into electrical analog signals. The light sources output light of wavelengths for use in the channels. The light intensity modulators of the channels intensity-modulate the light output from the light sources with the encoded signals converted into the electrical analog signals by the DA converters. The wavelength multiplexer outputs a wavelength-multiplexed signal obtained by wavelength-multiplexing the light intensity-modulated by the light intensity modulators.

  • Patent number: 10621083
    Abstract: A storage system selects from a plurality of physical areas constituting a physical address space as copy source physical areas, one or more non-additionally recordable physical areas each including a fragmented free area, and also selects a recordable physical area as a copy destination physical area. The storage system then writes one or more pieces of live data from the selected one or more copy source physical areas to the free area of the selected copy destination physical area on a per-strip or per-stripe basis, sequentially from the beginning of the free area. If the size of the write target data is such that it is not possible to write the write target data to the free area on a per-strip or per-stripe basis, then the storage system pads the write target data, and writes the padded write target data to the free area on a per-strip or per-stripe basis.
