Patent number: 7501488Abstract: The present invention is directed to a proteorhodopsin mutant having improved optical characteristics. One improved optical characteristic is having a lower pH (pKrh) at which equal concentrations of the acidic and basic spectral form of the proteorhodopsin molecules are present. Another improved optical characteristic is having a smaller difference in maximum absorption wavelength between the basic and the acidic form. The mutant comprises a mutation in a conserved amino acid residue of a proteorhodopsin variant, which causes spectral shifts. A preferred mutation site is a conserved histidine residue at amino acid position 75 of Bac31A8, or position 77 of Hot75m1, or its equivalent position of a proteorhodopsin variant. Another preferred mutation site is a conserved arginine residue at amino acid position 94 of Bac31A8, or position 96 of Hot75m1, or its equivalent position of a proteorhodopsin variant.Type: GrantFiled: November 26, 2003Date of Patent: March 10, 2009Assignee: Genencor International, Inc.Inventors: Rasmus B. Jensen, Bradley Kelemen

Publication number: 20080064941Abstract: An analyte monitor includes a sensor, a sensor control unit, and a display unit. The sensor control unit typically has a housing adapted for placement on skin and is adapted to receive a portion of an electrochemical sensor. The sensor control unit also includes two or more conductive contacts disposed on the housing and configured for coupling to two or more contact pads on the sensor. A transmitter is disposed in the housing and coupled to the plurality of conductive contacts for transmitting data obtained using the sensor. The display unit has a receiver for receiving data transmitted by the transmitter of the sensor control unit and a display coupled to the receiver for displaying an indication of a level of an analyte, such as blood glucose. An inserter having a retractable introducer is provided for subcutaneously implanting the sensor in a predictable and reliable fashion.Type: ApplicationFiled: September 6, 2007Publication date: March 13, 2008Inventors: Jeffery Funderburk, Duane Yamasaki, Brian VanHiel, Stephen Flynn, Bradley Kelemen

Patent number: 5654848Abstract: A reduced-height structure for a voice coil motor which forms a portion of the actuator in a disc drive data storage device includes a through opening in the base member of the disc drive housing within which the lower pole piece of the voice coil motor is mounted. A top pole piece of the Voice coil motor is mounted directly to the top cover of the disc drive housing and proper spacing between the top pole piece and the voice coil motor components mounted to the base a member is determined and maintained by a precisely machined surface in the base member. The lower pole piece is preferably mounted to the base member with cold-flowed brass rivets.Type: GrantFiled: September 30, 1992Date of Patent: August 5, 1997Assignee: Seagate Technology, Inc.Inventors: Michael Alan Maiers, Michael John Raffetto, Chul Soo Kim, Fredrick Frank Kazmierczak, Bradley Kelemen
