Publication number: 20240121637Abstract: A wireless communication monitoring system for monitoring a hardware failure of a wireless communication unit of a wireless communication device using a remote monitoring control device, in which the wireless communication device transmits or receives a predetermined radio signal to or from a monitoring device added or attached to the host device to perform a life and death check for checking an operation, and the remote monitoring control device detects a hardware failure of the wireless communication unit of the wireless communication device on the basis of a result of the life and death check received from the wireless communication device. This makes it possible to detect a failure that cannot be detected from information obtained from a device state request to a wireless communication device of the related art.Type: ApplicationFiled: February 17, 2021Publication date: April 11, 2024Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Akira MATSUSHITA, Mitsuru NISHINO, Munehiro MATSUI, Masaki SHIMA, Koichi HARADA, Hiroki SHIBAYAMA, Fumihiro YAMASHITA

Publication number: 20240097344Abstract: A reflector antenna includes: a radiator that radiates a radio wave; a main reflector that reflects the radio wave radiated from the radiator in a communication direction; an expansion panel that is attached to at least a part of the main reflector to increase an area of the main reflector; and a first adjustment unit that changes a position of the radiator, or a second adjustment unit that replaces the radiator with a radiator having a different radiation angle. This configuration makes it possible to implement a large-aperture antenna having excellent transportability and operability without preparing another antenna having a large aperture and replacing a standard antenna.Type: ApplicationFiled: December 3, 2020Publication date: March 21, 2024Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Koichi HARADA, Masaki SHIMA, Hiroki SHIBAYAMA, Fumihiro YAMASHITA

Patent number: 9330712Abstract: In a data conversion auxiliary module which is at a higher level than a file system in a disk management hierarchy, data stored in a storage medium, which becomes an object, is successively accessed. Then, a data conversion module captures a sector-unit access request to a device driver from the file system, converts data of a sector which is returned from the device driver, and writes the conversion data in the sector. Thereby, data conversion can be executed on a specific region of the storage medium, which is associated with the data in the storage medium.Type: GrantFiled: August 1, 2012Date of Patent: May 3, 2016Assignee: Humming Heads Inc.Inventors: Naoyuki Oe, Takahiro Shima, Yoshiyuki Matsumoto, Hiroki Shima, Yusuke Minamii, Takahiro Takeda

Publication number: 20140121733Abstract: The purpose of the present invention is to solve issues with conventional hyperthermia treatment for cancer. The present invention provides a cell activation device that is capable of suppressing the progress of cancer and contributing to the irradiation of cancer cells. This cell activation device (100) activates the gene restoration mechanism naturally hound in cells and supports cancer treatment, by cutting infrared rays having a wavelength greater than 7.5 ?m at which said rays works as heat rays and irradiating infrared rays having a wavelength that equals to or is smaller than 7.5 ?m on an affected area containing cancer cells. An infrared irradiation therapy using wave length of no more than 7.5 ?m is a gentle therapy that activates a latent function of human cells, such as activating the gene restoration mechanism.Type: ApplicationFiled: April 18, 2012Publication date: May 1, 2014Inventor: Hiroki Shima

Patent number: 8320771Abstract: A repeater includes a variable optical attenuating unit that collectively attenuates WDM optical signal input, an optical-attenuation adjusting unit that adjusts attenuation in the variable optical attenuating unit, and an optical amplifying unit that collectively amplifies and outputs the WDM optical signal collectively attenuated, to a downstream side. An optical-attenuation adjusting unit includes an input level detector; an output level detector; an output-level transmitting unit that receives information of a signal level of WDM optical signal output by a repeater at an upstream side and transmits information of a signal level of the WDM optical signal detected by the output level detector to a repeater at a downstream side; and an attenuation amount controller that controls the variable optical attenuating unit by calculating an attenuation amount thereof based on information of a signal level detected by the input level detector and a signal level received by the output-level transmitting unit.Type: GrantFiled: January 22, 2008Date of Patent: November 27, 2012Assignee: Mitsubishi Electric CorporationInventors: Tsuyoshi Yoshida, Toshiyuki Tokura, Takashi Sugihara, Katsuhiro Shimizu, Aritomo Uemura, Hiroki Shima, Kiyoshi Onohara
