Patent number: 11085760Abstract: Provided is a shape measurement sensor including a light-receiving unit and a calculation unit. The light-receiving unit includes a plurality of pixel pairs. Each of the pixel pairs includes a first pixel and a second pixel that is disposed side by side with the first pixel along a first direction. In the first pixel, as an incident position is closer to one end of the light-receiving unit in a second direction, an intensity of a first electric signals decreases. In the second pixel, as the incident position is closer to the one end, an intensity of a second electric signal increases. The calculation unit calculates the incident position in the second direction for each of the pixel pairs on the basis of the intensity of the first electric signal and the intensity of the acquired second electric signal.Type: GrantFiled: September 19, 2018Date of Patent: August 10, 2021Assignee: HAMAMATSU PHOTONIC K.K.Inventors: Munenori Takumi, Haruyoshi Toyoda, Yoshinori Matsui, Kazutaka Suzuki, Kazuhiro Nakamura, Keisuke Uchida

Patent number: 11011213Abstract: A memory system of a high-speed operation can be realized by reducing an influence of reflection signals etc. caused by branching and impedance mismatching in various wirings between a memory controller and a memory module, and an influence due to transmission delays of data, command/address, and clocks in the memory module. To this end, a memory system comprises a memory controller and a memory module mounted with DRAMs. A buffer is mounted on the memory module. The buffer and the memory controller are connected to each other via data wiring, command/address wiring, and clock wiring. The DRAMs and the buffer on the memory module are connected to each other via internal data wiring, internal command/address wiring, and internal cock wiring. The data wiring, the command/address wiring, and the clock wiring may be connected to buffers of other memory modules in cascade.Type: GrantFiled: July 22, 2019Date of Patent: May 18, 2021Assignee: LONGITUDE LICENSING LIMITEDInventor: Yoshinori Matsui
