  • Patent number: 11543972
    Abstract: The present disclosure is to optimize processes in a storage system. A storage system includes: a first controller including a first computing device and a first memory; a second controller including a second computing device and a second memory; and an interface circuit that transfers data between the first controller and the second controller. The interface circuit reads first compressed data from the second memory. The interface circuit decompresses the first compressed data to generate first uncompressed data, and writes the first uncompressed data into the first memory.

  • Patent number: 11452843
    Abstract: An injection device is described including a detection unit that includes an electrode that detects electrical characteristics of a biological tissue, a follow-up mechanism that follows motions of the biological tissue, and a puncture unit capable of puncturing the biological tissue. The injection device is configured to administer a predetermined substance to the biological tissue through a hollow portion defined in the puncture unit. A position of the puncture unit is specified based on a position of the electrode. The follow-up mechanism includes a spiral portion spirally extending around the puncture unit, and being stretchable and compressible along an extending direction of the puncture unit. Electrodes are disposed on an annular distal-end projected plane of the spiral portion, as seen from a distal end side of the puncture unit, along a circumferential direction of the puncture unit.
