Peter Kiesel, Meng H Lean, Oliver Schmidt, Armin R Völkel, Noble M Johnson: Sensing photons from objects in channels. Palo Alto Research Center Incorporated, Leading Edge Law Group, James T Beran, April 15, 2008: US07358476 (50 worldwide citation)

A fluidic structure includes a channel and along the channel is a series of sensing components to obtain information about objects traveling within the channel, such as droplets or other objects carried by fluid. At least one sensing component includes a set of cells of a photosensor array. The set ...

Peter Kiesel, Oliver Schmidt, Oliver Wolst: Using position-sensitive detectors for wavelength determination. Palo Alto Research Center Incorporated, Leading Edge Law Group, James T Beran, December 18, 2007: US07310153 (50 worldwide citation)

A chip-size wavelength detector includes a film with laterally varying transmission properties and a position-sensitive detector. The film transmits a different wavelength as a function of lateral position across the film. The position of a spot of light transmitted through the film will shift, depe ...

Peter Kiesel, Oliver Schmidt, Oliver Wolst: Photosensing throughout energy range and in subranges. Palo Alto Research Center Incorporated, Leading Edge Law Group, James T Beran, November 6, 2007: US07291824 (46 worldwide citation)

An integrated circuit (IC) includes a photosensor array, some cells of which are reference cells that photosense throughout an application's energy range, while other cells of which are subrange cells that photosense within respective subranges. For example, the subrange cells can receive photons in ...

Peter Kiesel, Oliver Schmidt: Obtaining analyte information. Palo Alto Research Center Incorporated, James T Beran, Leading Edge Law Group, October 7, 2008: US07433552 (43 worldwide citation)

Light, such as from an analyte-wavelength converter or other optical sensor, is propagated to a detector or transmission structure with an entry surface and with output positions such as in an exit surface. For example, the position of light output by such a detector can be used to detect presence o ...

Oliver Schmidt, Peter Kiesel, Patrick Y Maeda: Propagating light to be sensed. Palo Alto Research Center Incorporated, Leading Edge Law Group, James T Beran, January 1, 2008: US07315667 (43 worldwide citation)

Light to be sensed is spreaded across an entry surface of a transmission structure with a laterally varying energy transmission function. For example, the light could be output from a stimulus-wavelength converter, provided through an optical fiber, or it could come from a point-like source or broad ...

Oliver Schmidt, Setu Mohta, Peter Kiesel: Providing light to channels or portions. Palo Alto Research Center Incorporated, James T Beran, Leading Edge Law Group, June 10, 2008: US07386199 (39 worldwide citation)

A fluidic structure includes a channel, a portion of which can contain fluid. Light can propagate in the portion, such as in response to illumination. The refractive index of material at the portion's boundary can be higher than that of the fluid, and more than approximately 10% of intensity of ligh ...

Michael Bassler, Markus Beck, Peter Kiesel, Alex Hegyi, Tobias Buergel, Noble M Johnson: Transmitting/reflecting emanating light with time variation. Palo Alto Research Center Incorporated, Leading Edge Law Group, Mark W Hrozenchik, April 20, 2010: US07701580 (37 worldwide citation)

A filter arrangement can transmit and/or reflect light emanating from a moving object so that the emanating light has time variation, and the time variation can include information about the object, such as its type. For example, emanating light from segments of a path can be transmitted/reflected t ...

Oliver Schmidt, Peter Kiesel, Michael Bassler: Obtaining information from optical cavity output light. Palo Alto Research Center Incorporated, Leading Edge Law Group, James T Beran, March 10, 2009: US07502123 (33 worldwide citation)

Output light from an optical cavity includes, for each of a set of modes, an intensity function, and a mode's intensity function includes information, such as about an optical characteristic of an analyte or of a region. For example, the intensity function can include a peak, and its central energy, ...

Peter Kiesel, Oliver Schmidt, Michael Bassler: Photosensing optical cavity output light. Palo Alto Research Center Incorporated, James T Beran, Leading Edge Law Group, December 30, 2008: US07471399 (33 worldwide citation)

An optical cavity, such as a laser or transmissive cavity, that can contain an analyte provides a different intensity-energy function with analyte present than when absent. The intensity-energy functions can, for example, include respective peaks that are different in at least one of central energy, ...
