The abstract of the patent published by the U.S. Patent and Trademark Office states: “A storage control device controlling a storage system including a first storage device and a second storage device, the first storage device and the second storage device include a plurality of regions for storing data, respectively, a data transmission between the first storage device and the second storage device is executed by the region, the storage control device includes a memory, and a processor coupled to the memory and configured to determine a first region of the first storage device as a first transmitting target region, the first region having a first size, transmit, from the first storage device to the second storage device, second data having a second size smaller than the first size, and based on a response performance of the storage system during the transmitting of the second data, transmit first data stored in the first region from the first storage device to the second storage device.”

The patent application was filed on June 8, 2016 (15/176,694).

Storage system and allocating virtual volumes based on access frequency
Fujitsu Ltd., Kawasaki, Japan, has been assigned a patent (9,817,583) developed by Ogihara, Kazutaka, Hachioji, Japan, Oe, Kazuichi, Yokohama, Japan, and Kawaba, Motoyuki, Kawasaki, Japan, for a “storage system and method for allocating virtual volumes based on access frequency.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “An information processing device includes a processor. The processor is configured to allocate a plurality of allocation unit areas to a virtual volume from a first storage device and a second storage device. The processor is configured to generate evaluation information related to access for each of a plurality of divided areas into which each of the plurality of allocation unit areas is divided. The processor is configured to determine based on the generated evaluation information, when allocation to the virtual volume is changed from a first allocation unit area of the first storage device to a second allocation unit area of the second storage device, a first data transfer order of transferring data in divided area units from the first allocation unit area to the second allocation unit area. The processor is configured to transfer the data in accordance with the first data transfer order.”

The patent application was filed on April 23, 2014 (14/259,333).

Driving assistance
Fujitsu Ltd., Kawasaki, Japan, has been assigned a patent (9,815,478) developed by Tsuyunashi, Masashi, Yamato, Toshitaka, Tanaka, Shogo, Hashimoto, Yoshikazu, and Ohta, Takashi, Kobe, Japan, for a “driving assistance system and driving assistance method.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A driving assistance system includes a history storage unit, a behavior detecting unit, a state determining unit, and a notifying unit. The history storage unit stores a behavior history which is a past behavior history of a driver. The behavior detecting unit detects a current behavior of the driver. The state determining unit determines an unsafe state by comparing the transition of the behavior detected by the behavior detecting unit with the behavior history of the driver corresponding to a current driving path. If the state determining unit determines the unsafe state, the notifying unit gives notification to the driver.”

The patent application was filed on November 6, 2015 (14/935,042).

Storage control
Fujitsu Ltd., Kawasaki, Japan, has been assigned a patent (9,811,274) developed by Kanai, Hideyuki, Kawasaki, Japan, for a “storage control apparatus and copy control method.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “When the capacity of a buffer region runs short, storing a first generation data set, a second generation data set, and a third generation data set, a control unit selects the first generation data set as a designated data set. The control unit creates, and stores in a storage unit, update record information based on the first generation data set. The control unit identifies the position where the first generation data set is to be stored in the copy source volume according to correspondence relation information, and updates the copy source volume with the first generation data set. The control unit deletes the first generation data set from the buffer region, and also deletes the correspondence relation information corresponding to the first generation data set from the storage unit.”

The patent application was filed on July 8, 2015 (14/793,777).

Controlling storage, and non-transitory computer-readable storage medium
Fujitsu Ltd., Kawasaki, Japan, has been assigned a patent (9,804,780) developed by Oe, Kazuichi, Yokohama, Japan, and Kawaba, Motoyuki, Kawasaki, Japan, for a “storage apparatus, method of controlling storage apparatus, and non-transitory computer-readable storage medium storing program for controlling storage.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A storage apparatus is provided, including a first storage device, a second storage device having an access speed higher than an access speed of the first storage device, a monitor that monitors a write access load for the first storage device, a comparator that compares the write access load for the first storage device monitored by the monitor, with a load threshold, and a switch that causes write access target data to be written into the first and second storage devices, when it is determined by the comparator that the write access load for the first storage device does not exceed the load threshold, while causing the write access target data to be written into the first storage device, when it is determined by the comparator that the write access load for the first storage device exceeds the load threshold.”

The patent application was filed on November 4, 2014 (14/532,050).
