Publication number: 20130235424Abstract: When a first remote panel accepts an operation to move a display screen, the first remote panel transmits information on the operation to a relay server. The relay server determines a destination display screen based on the received information, and transmits information on the destination display screen to each of an MFP (Multifunction Peripheral), the first remote panel, and a second remote panel. The relay server transmits data on the destination display screen to each of the first and second remote panels. After transmitting the information on the destination display screen, the relay server receives data on a neighboring screen of the destination display screen from the MFP.Type: ApplicationFiled: March 7, 2013Publication date: September 12, 2013Applicant: Konica Minolta Business Technologies, Inc.Inventor: Kei YAMADA

Patent number: 8488152Abstract: In the case that a control section takes out a print job from an output queue, the control section notifies a terminal device being a transmitting source of the print job of a termination notice that a period to permit to change a print condition related to the print job has been terminated. However, when the control section receives a change request to change the printing condition for the print job before notifying the termination notice, the control section replaces the print job registered in the output queue with a print job having a changed printing condition in accordance with the change request.Type: GrantFiled: April 7, 2009Date of Patent: July 16, 2013Assignee: Konica Minolta Business Technologies, Inc.Inventor: Kei Yamada

Patent number: 8422694Abstract: In a source sound separator, first and second target sound predominant spectra are generated respectively by first and second processing operations for linear combination for emphasizing the target sound, using received sound signals of two microphones arrayed at a distance from each other. A target sound suppressed spectrum is generated by processing for linear combination for suppression of the target sound, using the two received sound signals. Further, a phase signal containing a larger amount of signal components of the target sound and exhibiting directivity in the direction of the target sound is generated by processing of linear combination, using the two received sound signals. The target sound and the interfering sound are separated from each other using the first and second target sound predominant spectra, the target sound suppressed spectrum, and the phase signal.Type: GrantFiled: December 10, 2010Date of Patent: April 16, 2013Assignees: Oki Electric Industry Co., Ltd., Waseda UniversityInventors: Makoto Morito, Takashi Yazu, Kei Yamada, Tetsunori Kobayashi, Kenzo Akagiri, Tetsuji Ogawa
