Abstract: Methods, systems and apparatus for providing a notification of a wet floor are provided. A scrubbing robot for scrubbing a floor and having one or more liquid carrying components has a sensor coupled to it positioned for collecting data about an area of the floor proximate to the scrubbing robot and along a path over which the robot has travelled. An application is stored on the computer for determining that liquid is on the floor by analysing the data for a presence of a second set of parameters corresponding to or crossing (from above to below or from below to above) a set of threshold parameters that is indicative of the presence of liquid on the floor. A notification module coupled to the scrubbing robot issues at least one of a human detectable and a computer detectable notification in response to the application determining that liquid is on the floor.

Abstract: The Raman scattering spectroscopic method according to the present invention include: preparing a chip having a channel in which a nanostructure is formed; introducing an analyte solution into a part of the channel in the chip; irradiating an interface of the analyte solution with a laser beam; and measuring Raman scattering light induced by the irradiation of the laser beam. The measurement may be performed, with a fixed laser beam irradiation position, both in a state where the interface of the analyte solution is included in the laser-beam-irradiation area and in a state where the interface of the analyte solution is not included in the laser-beam-irradiation area, or may be performed keeping the state where the interface of the analyte solution is maintained in the laser-beam-irradiation area by controlling the laser-beam-irradiation area according to the movement of the interface due to evaporation of the analyte solution.

Abstract: Swept-source Raman spectroscopy uses a tunable laser and a fixed-wavelength detector instead of a spectrometer or interferometer to perform Raman spectroscopy with the throughput advantage of Fourier transform Raman spectroscopy without bulky optics or moving mirrors. Although the tunable laser can be larger and more costly than a fixed wavelength diode laser used in other Raman systems, it is possible to split and switch the laser light to multiple ports simultaneously and/or sequentially. Each site can be monitored by its own fixed-wavelength detector. This architecture can be scaled by cascading fiber switches and/or couplers between the tunable laser and measurement sites. By multiplexing measurements at different sites, it is possible to monitor many sites at once. Moreover, each site can be meters to kilometers from the tunable laser. This makes it possible to perform swept-source Raman spectroscopy at many points across a continuous flow manufacturing environment with a single laser.

Abstract: Apparatus and methods relating to photonic bandgap optical nanostructures are described. Such optical nanostructures may exhibit prohibited photonic bandgaps or allowed photonic bands, and may be used to reject (e.g., block or attenuate) radiation at a first wavelength while allowing transmission of radiation at a second wavelength. Examples of photonic bandgap optical nanostructures includes periodic and quasi-periodic structures, with periodicity or quasi-periodicity in one, two, or three dimensions and structural variations in at least two dimensions. Such photonic bandgap optical nanostructures may be formed in integrated devices that include photodiodes and CMOS circuitry arranged to analyze radiation received by the photodiodes.

Abstract: Described herein are 3D single-molecule super-resolution imaging systems and methods. The provided systems and methods use modulation interferometry and phase-sensitive detection techniques that achieve less than 2 nanometer axial localization precision, which is well below the 5-10-nanometer-sized individual protein components. To illustrate the capability of this technique in probing the dynamics of complex macromolecular machines, (1) movement of individual multi-subunit E. coli RNA Polymerases were visualized through the complete transcription cycle, (2) kinetics of the initiation-elongation transition were dissected, (3) the conformational changes from the open initiation complex to the elongation complex were analyzed, and (4) the fate of σ70 initiation factors during promoter escape were determined.
