Patent number: 7753966Abstract: It is to provide a hair dye stabilizer capable of stably storing a readily oxidizable compound in a hair dye, especially an oxidizing dye intermediate or a coupler and effective for remarkably improving the offensive odor problem. Furthermore, it is to provide a hair dye stabilizer giving improvement in damage on the hair, hardly irritating the skin, and free from adverse effects on the dyeing ability of the hair dye. As the active component constituting the hair dye stabilizer, a compound which is a mercapto-hydrocarbon compound and/or a thiol alcohol compound and does not contain a functional group reactive with a dye intermediate or a coupler is used. A readily oxidizable compound and the like in a hair dye can be stably stored by the use of an extremely small amount of the stabilizer.Type: GrantFiled: July 10, 2007Date of Patent: July 13, 2010Assignee: Takasago International CorporationInventors: Junko Nagano, Kazuki Sugiyama, Kyoko Hirano, Kunihide Hoshino, Takashi Aida

Publication number: 20100141162Abstract: An LED driver circuit powers a plurality of LED arrays coupled in parallel, each LED array having one or more LEDs coupled in series. A power converter converts an input signal from a power source into an output signal across the LED arrays. A switching element is coupled in series with each of the LED arrays and alternates between first and second switch states in response to lighting control signals. A control circuit generates the lighting control signals and supplies them to the switching elements to sequentially operate one or more of the switching elements in the first switch state during each of a plurality of predetermined time periods in a light emitting state for the LED driver circuit.Type: ApplicationFiled: December 3, 2009Publication date: June 10, 2010Inventors: Kouji Matsumoto, Kenichi Takmatsu, Tsukasa Ogura, Masashi Kitima, Takashi Aida

Publication number: 20080019578Abstract: A high security identification card includes an on-board memory for stored biometric data and an on-board sensor for capturing live biometric data. An on-board processor on the card performs a matching operation to verify that the captured biometric data matches the locally stored biometric data. Only if there is a positive match is any data transmitted from the card for additional verification and/or further processing. Preferably, the card is ISO SmartCard compatible. In one embodiment, the ISO SmartCard functions as a firewall for protecting the security processor used for storing and processing the protected biometric data from malicious external attack via the ISO SmartCard interface. In another embodiment, the security processor is inserted between the ISO SmartCard Interface and an unmodified ISO SmartCard processor and blocks any external communications until the user's fingerprint has been matched with a previously registered fingerprint.Type: ApplicationFiled: September 28, 2007Publication date: January 24, 2008Applicant: IVI Smart Technologies, Inc.Inventors: Tamio Saito, Wayne Drizin, Takashi Aida
