Patent number: 8569001Abstract: A method for detecting lysosomal storage diseases including the steps of performing an assay for a single species of glycosaminoglycan contained in a specimen and correlating results of the assay with lysosomal storage diseases. A body fluid such as urine or blood can be employed as a specimen. The assay can be performed by use of a polypeptide that is capable of specifically binding to a glycosaminoglycan-containing molecule. The polypeptide may be an antibody, or a polypeptide having an antigen-binding site of an antibody.Type: GrantFiled: April 21, 2011Date of Patent: October 29, 2013Assignees: Seikagaku Corporation, Saint Louis UniversityInventors: Kazuo Okamura, Shuichi Miyaura, Shunji Tomatsu

Patent number: 8447167Abstract: A recording/reproduction device is provided wherein service content having interactivity can be restored even when recorded. In recording mode, a transport stream from a receiving device 34 is received and a conversion device 36 converts this to a packet-multiplexed stream in a condition suitable for recording, which is then output as a converted stream. The conversion device 36 selects packets relating to a desired service from the transport stream and, of these packets, selects only packets needed for reproduction and uses these to generate a converted stream. A recording device 38 records this converted stream on a recording medium 44. In reproduction mode, the converted stream from recording medium 44 is read by means of a reading device 42 and supplied to a restoration device 40. Restoration device 40, in accordance with the content of this converted stream, restores and outputs a service content signal (for example a composite signal such as NTSC).Type: GrantFiled: July 2, 2008Date of Patent: May 21, 2013Assignee: Panasonic CorporationInventors: Shinji Nabeshima, Kazuo Okamura, Naoya Takao

Patent number: 8191009Abstract: The present invention provides a device and a method for displaying appropriately on the display area for each processing unit such as an application according to the applied equipment. The CPU 12 processes display area acquisition requests from a plurality of processing units R1-Rn according to a display management program. The display management program decides whether use of the display area is allowed to each processing unit, considering the relationship of the plurality of display areas requested from each processing unit R1-Rn. Each processing unit R1-Rn executes display processing for the display area for which use is allowed. In this way, whether use is allowed is notified from the display management program to each processing unit R1-Rn after each processing unit R1-Rn sends the display area acquisition request. As a consequence, display in a plurality of areas by each processing unit R1-Rn can be controlled appropriately.Type: GrantFiled: December 22, 2003Date of Patent: May 29, 2012Assignee: Panasonic CorporationInventors: Takuya Sekiguchi, Taketo Yoshii, Kouichi Yasutake, Kazuo Okamura

Patent number: 7739619Abstract: A display control device for controlling a display of a display device responding to display processing from a plurality of processing units. A display controlling program controls the display device in response to at least one processing unit. The display controlling program receives a request from one processing unit to acquire one of predefined display areas, and determines whether to provide an authorization to acquire one of a plurality of predefined display areas in response to an acquisition request from the one processing unit. When a plurality of requests to acquire the same one of predefined display areas from a plurality of processing units are received, authorization is provided to a single processing unit that made one of the requests to acquire the same one of predefined display areas. The display device is instructed by a processor, based on the display controlling program. A memory, connected to the processor, stores the display controlling program.Type: GrantFiled: April 25, 2005Date of Patent: June 15, 2010Assignee: Panasonic CorporationInventors: Takuya Sekiguchi, Taketo Yoshii, Kouichi Yasutake, Kazuo Okamura
