Patent number: 10439255Abstract: Light is transmitted through or from a separator of a battery cell or scattered within a battery cell and received by one or more light detectors. The light that is normally transmitted through the separator is scattered, absorbed, wavelength-shifted or otherwise distorted by an impending fault in the vicinity of or within the separator. The change in light due to the impending fault is measured by a detector and a signal from the detector is processed to identify the impending fault so that a warning can be generated indicative of the impending fault.Type: GrantFiled: August 9, 2013Date of Patent: October 8, 2019Assignee: Battelle Memorial InstituteInventors: James E. Dvorsky, Steven M. Risser, James H. Saunders, Alexander C. Morrow, David W. Nippa

Patent number: 8726317Abstract: A method of converting a modulated optical signal to an encoded electrical signal is provided. The method utilizes a device comprising an electrooptic sideband generator, an optical filter, and an optical/electrical converter. Initially, the modulated optical signal, which carries encoded optical data, is directed to an optical input of the electrooptic sideband generator. The electrooptic sideband generator is driven to generate frequency sidebands about a carrier frequency of the input optical signal. The optical filter is utilized to discriminate between the frequency sidebands and the carrier frequency and combine sidebands-of-interest to yield at least one frequency-converted optical signal comprising a millimeter wave modulation frequency. The frequency converted optical signal carries the encoded optical data and the modulation frequency is a function of the spacing of the sidebands-of-interest.Type: GrantFiled: September 30, 2008Date of Patent: May 13, 2014Assignee: Battelle Memorial InstituteInventors: David W.

Patent number: 7215851Abstract: Methods of attenuating, delaying the phase, and otherwise controlling an optical signal propagating along a waveguide are provided. According to one method, a variable optical attenuator structure is provided comprising a waveguide core, a cladding, an electrooptic polymer, and a set of control electrodes. The core, the cladding, and the electrooptic polymer are configured such that an increase in the index of refraction of the polymer causes a substantial portion of an optical signal propagating along the waveguide core to couple into a relatively high index region of the electrooptic polymer above the waveguide core, so as to inhibit return of the coupled signal to the waveguide core. Another embodiment of the present invention introduces a phase delay in the coupled optical signal and permits return of the coupled signal to the waveguide core. An additional embodiment contemplates the use of a ridge waveguide structure to enable control of the optical signal.Type: GrantFiled: November 7, 2005Date of Patent: May 8, 2007Assignee: Optimer Photonics, Inc.Inventors: David W.
