Patent number: 9336424Abstract: There is provided a barcode reader that decode of a barcode is possible with easy processes even in a case where reflectivity around the barcode is higher than reflectivity at bright portions of the barcode. The barcode reader comprises: an edge deleter configured to delete the position information and polarity information on an unnecessary edge which arises due to a difference between a strength of a reflected light from a quiet zone of the barcode and a strength of a reflected light from an adjacent portion of the quiet zone, wherein, on detecting two successive edges which have the same polarity, the edge deleter determines an edge which is closer to an end portion of a scan as the unnecessary edge and deletes the position information and polarity information on the unnecessary edge.Type: GrantFiled: November 18, 2013Date of Patent: May 10, 2016Assignee: NEC PLATFORMS, LTDInventors: Hiroshi Shigemitsu, Masao Gotoh, Hiroshi Tsuruki, Masato Teraoka

Patent number: 8282813Abstract: A biosensor measurement device for providing accurate measurement results within a short period of time by using only a very small amount of sample. The biosensor measurement device includes a power source, which is connected to a voltage regulator, a measurement instrument, and a controller for supplying power. When the biosensor chip is connected to the biosensor measurement device and a voltage is applied, the measurement instrument begins the measurement of a current value for the biosensor.

Publication number: 20100069792Abstract: A biosensor cartridge capable of performing puncturing in an exact position, and easily collecting and measuring a sample of a puncture hole without requiring the operation of bringing a sample collection opening close to the puncture hole is provided. When tip portion 11a of biosensor chip body 11 is pushed against a subject M, elastic body 20 protruding from a tip portion 11a of biosensor chip body 11 is compressed, and puncturing tool 12 for puncturing protrudes. Thus, the subject M can be punctured. Additionally, if a pushing force is weakened, puncturing tool 12 is extracted from the subject M by the restoring force of elastic body 20, and the sample R flows out of the puncture hole. Additionally, cover member 19 is provided around biosensor chip body 11. Thus, when puncturing is performed by thin plate-shaped biosensor cartridge 10, biosensor chip body 11 can be prevented from deforming, and puncturing can be accurately performed in a desired puncturing position.Type: ApplicationFiled: November 1, 2007Publication date: March 18, 2010Applicants: National Institute of Advanced Industrial Science and Technology, Sumitomo Electric Industries, Ltd.Inventors: Tsuyoshi Fujimura, Hideaki Nakamura, Tomoko Ishikawa, Masao Gotoh, Isao Karube, Takahiko Kitamura, Shingo Kaimori, Akira Harada, Hiroto Nakajima, Hiroshi Hayami, Toshifumi Hosoya

Publication number: 20100004559Abstract: A biosensor cartridge capable of making the collected amount of a sample required for measurement into a small quantity to reduce a user's burden, and easily collecting and measuring a sample of a puncture hole without requiring the operation of bringing a sample collection opening close to the puncture hole is provided. When one end portion of biosensor chip is pushed against subject, elastic body is compressed, and puncturing tool can protrude and perform puncturing. Additionally, if a pushing force is weakened, puncturing tool is extracted from subject by the restoring force of elastic body, and blood (sample) flows out of the puncture hole. In this case, since the puncture hole, and sample collection opening provided at biosensor chip are contained in enclosed half-open space formed by elastic body, even a small amount of blood (sample) can also be easily collected.Type: ApplicationFiled: December 17, 2007Publication date: January 7, 2010Applicants: NATIONAL INSTITUTE OF ADVANCED INDUSTRIAL SCIENCE AND TECHNOLOGY, SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Tsuyoshi Fujimura, Hideaki Nakamura, Masao Gotoh, Isao Karube, Tomoko Ishikawa, Takahiko Kitamura, Shingo Kaimori, Hiroto Nakajima, Hiroshi Hayami, Toshifumi Hosoya

Publication number: 20090299225Abstract: There is provided a biosensor chip where the collecting amount necessary for the measurement is made small whereby burden of a user is reduced and, at the same time, a sample at a puncture opening is able to be easily collected and measured without an operation of making the sample collection opening nearer the puncture opening. When an end of a main body chip is pushed onto a test body, an elastic body installed at an end of the main body chip is compressed and a device for puncture is produced whereby the test body is able to be punctured. When the pushing force is made weak, the device for puncture is pulled out from the test body due to resilience of the elastic body and a sample is flown out from the puncture opening.Type: ApplicationFiled: April 17, 2007Publication date: December 3, 2009Applicant: SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Takahiko Kitamura, Shingo Kaimori, Akira Harada, Toshifumi Hosoya, Tsuyoshi Fujimura, Isao Karube, Masao Gotoh, Hideaki Nakamura, Tomoko Ishikawa
