Patent number: 6797018Abstract: An electrochemical energy storage device includes a number of solid-state thin-film electrochemical cells which are selectively interconnected in series or parallel through use of an integrated interconnect board. The interconnect board is typically disposed within a sealed housing which also houses the electrochemical cells, and includes a first contact and a second contact respectively coupled to first and second power terminals of the energy storage device. The interconnect board advantageously provides for selective series or parallel connectivity with the electrochemical cells, irrespective of electrochemical cell position within the housing. Fuses and various electrical and electro-mechanical devices, such as bypass, equalization, and communication devices for example, may also be mounted to the interconnect board and selectively connected to the electrochemical cells.Type: GrantFiled: May 30, 2003Date of Patent: September 28, 2004Assignees: 3M Innovative Properties Company, Hydro-Quebec CorporationInventors: Jean Rouillard, Christophe Comte, Dominik Daigle, Ronald A.

Patent number: 6717124Abstract: The present invention provides for very rapid autofocusing of optical scanning systems. If a sample is sufficiently out of focus, the focal error signal used to focus a conventional half-blocked system can become saturated. Multiple steps toward the focus position then typically are required to bring the system into the operational range. To minimize this, a light adjustment system is provided to reduce the amount of light impinging on the half-blocked system when the focal error signal is at or near saturation. The half-blocked system then becomes primary controller again, and can move the system into a position generally close to the correct focal point. The light adjustment system then can be deactivated, but since the system now is much closer to focus, the half-blocked system can quickly bring the system into final focus. Alternatively, the photodetectors used to generate the focal error signal are segmented.Type: GrantFiled: April 11, 2003Date of Patent: April 6, 2004Assignee: 3M Innovative Properties CompanyInventors: Matthew R. C. Atkinson, Orlin B. Knudson

Patent number: 6664111Abstract: Sensing elements, sensor systems and methods for determining the concentration of oxygen and oxygen-related analytes in a medium are provided. The sensing element comprises a solid polymeric matrix material that is permeable to oxygen or an oxygen related analyte and an indicator that is covalently bonded to the solid polymeric matrix material. The indicator is a luminescent platinum group metal polyaromatic chelate complex capable of having its luminescence quenched by the presence of oxygen. The polyaromatic complex comprises three ligands, at least one of which is a bidentate diphenylphenanthroline. The polyaromatic complex is distributed substantially homogenously throughout the matrix material and is covalently bonded to the matrix material via a linker arm. The linker arm is attached to a phenyl group of a diphenylphenanthroline ligand and to the backbone of the polymeric matrix material.Type: GrantFiled: August 22, 2001Date of Patent: December 16, 2003Assignee: 3M Innovative Properties CompanyInventors: James G.

Patent number: 6171304Abstract: A method of monitoring the contact of a biomedical electrode to skin of a patient is disclosed, where the phase angle of current flow through one portion of the electrode is compared to the phase angle of current flow through another portion of the electrode. The two portions are both electrical conductors, one having a lossy dielectric surface and the other bare metal. Any monitoring of an electrical interface is possible based on the difference in phase angle. Lift of any portion of the electrode from contact with skin of a patient can be monitored more easily than using conventional Contact Quality Monitoring circuitry and “split plate patient plates.Type: GrantFiled: February 23, 1999Date of Patent: January 9, 2001Assignee: 3M Innovative Properties CompanyInventors: Samuel G.

Patent number: 6104967Abstract: A distributed energy storing system employing a communications network is disclosed. A distributed battery system includes a number of energy storing modules, each of which includes a processor and communications interface. In a network mode of operation, a battery computer communicates with each of the module processors over an intra-battery network and cooperates with individual module processors to coordinate module monitoring and control operations. The battery computer monitors a number of battery and module conditions, including the potential and current state of the battery and individual modules, and the conditions of the battery's thermal management system. An over-discharge protection system, equalization adjustment system, and communications system are also controlled by the battery computer. The battery computer logs and reports various status data on battery level conditions which may be reported to a separate system platform computer.Type: GrantFiled: July 25, 1997Date of Patent: August 15, 2000Assignee: 3M Innovative Properties CompanyInventors: Ronald A.

Patent number: 6100702Abstract: An apparatus and method for detecting a breach in an electrically insulating surface of an electrically conductive power system enclosure within which a number of series connected energy storing devices are disposed. The energy storing devices disposed in the enclosure are connected to a series power connection. A detector is coupled to the series connection and detects a change of state in a test signal derived from the series connected energy storing devices. The detector detects a breach in the insulating layer of the enclosure by detecting a state change in the test signal from a nominal state to a non-nominal state. A voltage detector detects a state change of the test signals from a nominal state, represented by a voltage of a selected end energy storing device, to a non-nominal state, represented by a voltage that substantially exceeds the voltage of the selected opposing end energy storing device.Type: GrantFiled: July 25, 1997Date of Patent: August 8, 2000Assignees: 3M Innovative Properties Company, Hydro-Quebec CorporationInventors: Ronald A.

Patent number: 5952815Abstract: An apparatus and method for regulating the charge voltage of a number of electrochemical cells connected in series is disclosed. Equalization circuitry is provided to control the amount of charge current supplied to individual electrochemical cells included within the series string of electrochemical cells without interrupting the flow of charge current through the series string. The equalization circuitry balances the potential of each of the electrochemical cells to within a pre-determined voltage setpoint tolerance during charging, and, if necessary, prior to initiating charging. Equalization of cell potentials may be effected toward the end of a charge cycle or throughout the charge cycle. Overcharge protection is also provided for each of the electrochemical cells coupled to the series connection.Type: GrantFiled: July 25, 1997Date of Patent: September 14, 1999Assignees: Minnesota Mining & Manufacturing Co., Hydro-Quebec CorporationInventors: Jean Rouillard, Christophe Comte, Ronald A.
