Abstract: An optical proximity sensor includes a housing, an optical emitter, and an optical detector. A first light guide disposed in a first chimney of the housing is configured to direct light from the optical emitter through the first chimney towards a target location. A second light guide disposed in a second chimney of the housing is configured to direct a returned portion of the light emitted from the optical emitter through the second chimney towards the optical detector.

Abstract: A system for coupling photometers to an incubation ring for use in in vitro diagnostics comprises one or more light sources, and an incubation ring assembly, and two photometers. An incubation ring assembly comprises an internal trough and an external trough. Each trough comprises (a) an internal wall comprising an internal aperture and (b) an external wall comprising an external aperture. A first photometer comprises: a first optics housing directing light from the light sources through the external aperture of the internal trough, and a first detector positioned to receive the light through the internal aperture of the internal trough. A second photometer comprises a second optics housing directing the light from the light sources through the internal aperture of the external trough, and a second detector positioned to receive the light through the external aperture of the external trough.

Abstract: A system may have a support structure and a glass layer that separate an exterior region surrounding the system from an interior region. Components may be mounted in the interior region. The components may include an optical component. The glass layer may have a first area that overlaps the optical component and that serves as an optical component window for the optical component. The glass layer may also have a second area that surrounds the first area and does not overlap the optical component. The first area may be selectively weakened relative to the second area to prevent excessive glass fracturing during a damage event from obscuring the optical component. Selective weakening may be provided with laser-induced-damage features, recesses from local thinning, and/or glass-weakening deposited thin films such as physical vapor deposition thin-film coatings of inorganic dielectric.

Abstract: A mail screening apparatus is provided to perform the inspection of mail or similar objects. Terahertz inspection is used to localize potential suspicious areas by imaging the contents inside the envelope or small parcel. The mail screening apparatus includes a primary and a secondary inspection zone, preferably allowing inspection of the mail in a normal and a zoomed mode, respectively. The same light source, image capture device and intervening optical components are used in both normal and zoomed modes. Metal detection may optionally be used to enhance awareness in the presence of metallic content. In one implementation, metal detection zones are provided in an orthogonal configuration with respect to the primary inspection zone used for terahertz imaging to accommodate for both manual and automatic inspection of mail.

Abstract: A method and system for identification of light source types includes detecting individual photons for a measurement time period to provide a times series of individual photon events, segmenting the time series into a plurality of time bins, and determining a number of detected photons within each time bin to provide a time series of photon counts, determining a probability distribution P(n) from the time series of photon counts, the probability distribution providing the probability of detection of n photons (n=0 . . . nmax), inputting each of the values of P(n) as a nmax+1 component feature vector into a single neuron neural network that has been previously trained on a plurality of light source types, and receiving as output a classifier that has a value that identifies the light source type. An average number of photons in the plurality of time bins is less than one photon.
