Abstract: Example systems and methods of UV disinfection of surfaces and/or air are presented which can utilize multiple peak wavelengths of UV light and utilize feedback control with UV light sensors. Some example systems and methods can facilitate sanitation of spaces which can be occupied by people and/or animals such as an interior room or space of a building or mode of transportation, or even an outdoor gathering space. Additionally, or alternatively, some example systems can include a compartment which is configured to block light exposure to people and/or animals during sanitation and into which objects can be placed for sanitation.

Abstract: Embodiments of the invention provide a method and system that allows parameters of a desired target image to be determined from hyperspectral imagery of scene. The parameters may be representative of various aspects of the scene being imaged, particularly representative of physical properties of the scene. For example, in some medical imaging contexts, the property being imaged may be blood perfusion or oxygenation saturation level information per pixel. In one embodiment the parameters are obtained by collecting lower temporal and spatial resolution hyperspectral imagery, and then building a virtual hypercube of the information having a higher spatial resolution using a spatiospectral aware demosaicking process, the virtual hypercube then being used for estimation of the desired parameters at the higher spatial resolution. Alternatively, in another embodiment, instead of building the virtual hypercube and then performing the estimation, a joint demosaicking and parameter estimation operation is performed to obtain the parameters. Various white level and spectral calibration operations may also be performed to improve the results obtained. While establishing functional and technical requirements of an intraoperative system for surgery, we present iHSI system embodiments that allows for real-time wide-field HSI and responsive surgical guidance in a highly constrained operating theatre. Two exemplar embodiments exploiting state-of-the-art industrial HSI cameras, respectively using linescan and snapshot imaging technology, were investigated by performing assessments against established design criteria and ex vivo tissue experiments. We further report the use of one real-time iHSI embodiment during an ethically-approved in-patient clinical feasibility case study as part of a spinal fusion surgery therefore successfully validating our assumptions that our invention can be seamlessly integrated into the operating theatre without interrupting the surgical workflow.

Abstract: The invention(s) cover a sensor and method of fabrication, the sensor including: a substrate; and a distribution of nanoparticles patterned onto the substrate as a set of regions. In variations, the sensor (100) can further include one or more channels in fluid communication with the distribution of nanoparticles. In variations, different nanoparticle regions can be optionally functionalized with different probe molecules in order to provide additional functionality with respect to the assay(s) being performed using the sensor (100). Additionally or alternatively, in variations, unoccupied regions of the substrate (110) and/or nanoparticle surfaces can optionally include passivated surfaces to prevent non-specific binding, without significantly shifting the LSPR wavelength, in order to significantly improve signal-to-noise ratio (SNR) provided by the sensor. The sensor can be used for performance of multiplexed assays (e.g., for infectious disease panels) with processing of different types of sample material.

Abstract: Systems and methods for collecting and analyzing lighting conditions associated with a physical space in order to effect circadian-effective design. According to certain aspects, a data capture machine may include various sensors and components, such as at least one image sensor that captures digital images of a set of luminaires, at least one laser that detects physical objects as well as the location of the data capture machine in the physical space, a detector that collects a set of spectral power distribution (SPD) measurements, and a video capture device that collects images at a set of locations of the physical space. The data capture machine may aggregate the captured information and generate an electronic file that a computing device may use to present a visual representation of the lighting conditions of the physical space. This representation may then enable a lighting designer to evaluate the non- visual impact of illumination, and offer tools to improve the design.

Abstract: Apparatus for stand-off Raman spectroscopy, comprising optical imaging device (e.g. a sight, e.g. of a rifle), Laser, Optical apparatus (optionally in the form of an adapter) with a wavelength band filter and optical dispersion means (e.g. grating) to disperse a Raman spectrum to an image sensor, and focusing means wherein the laser is a pulsed laser, and each of the detector elements of the array comprises a frequency band pass filter for detecting light pulses in preference to background radiation. Each detector element is provided with a first charge storage element to store charge, connected via a frequency band pass filter to a second charge storage element arranged to store charge preferentially resulting from high frequency light pulses. This may be performed in the short wave infrared spectrum. The image sensor can also have conventional detector elements, enabling viewing of a scene whilst simultaneously obtaining a Raman spectrum of a target in the scene. Advantageously this may be implemented in a rifle sight, optionally by means of an adapter arranged so that the rifle sight can be readily switched from conventional viewing mode to stand off Raman spectroscopy mode.
