Abstract: A display system may include a waveguide, an input coupler with a first surface relief grating (SRG), and an output coupler with a second SRG. A display module may produce image light that is coupled into the waveguide by the first SRG. The first SRG may have an input vector non-parallel with respect to a normal axis of the waveguide. The display module may have an optical axis tilted with respect to the input vector by a non-zero angle. A prism may redirect the image light from the module to the first SRG in a direction parallel to the input vector. The module may include lens elements with an optical axis offset with respect to the center of the field of the image light. This may cause the lens elements to output the image light in a direction parallel to the input vector of the first SRG.

Abstract: Embodiments of the present disclosure provide systems, methods, and apparatuses for addressing the above problems through the use of access rules that involve analyzing historical access request result data for various data elements individually and in combination over a predefined time interval. An automated determination can be made for whether a transaction can be authenticated based upon the historical access request result data (e.g., ultimately, deciding whether the data element or set of data elements are associated with a valid access request).

Abstract: A display may include illumination optics (36), a spatial modulator (40) and a waveguide (26). The illumination optics may produce illumination that is modulated by the spatial modulator to produce image light. The waveguide may direct the image light towards an eye box. The illumination optics may include light sources (58) an X-plate (44), and at least one Fresnel lens (60) interposed between the light sources and the X-plate. The Fresnel lenses may minimize the size of the illumination optics while still exhibiting satisfactory optical performance. The spatial light modulator may include a reflective display panel (50) and a powered prism (48) with a reflective coating on a curved reflective surface. The powered prism may optimize f-number while minimizing the volume of the spatial light modulator. The collimating optics may include a diffractive optical element (56) that compensates for thermal effects and chromatic dispersion in the display.

Abstract: Devices and methods are provided to overdrive or underdrive a display panel to account for display pixel hysteresis due to several frames of pixel history. An electronic device may include an electronic display and processing circuitry. The electronic display includes a number of display pixels. The processing circuitry may generate image data for the display pixels. The processing circuitry may receive a current frame value of the image data targeted for a first display pixel and, based at least in part on the current frame value and a pixel history of the first display pixel—may indicate a gray level for a number of previous frames—generate a compensated value by which to drive the first pixel to overcome pixel hysteresis to reach the desired luminance at an initial response.

Abstract: A hybrid operation of a license plate recognition (LPR) system and infrastructure monitoring is provided. The system takes advantage of a first mode of operation of the LPR system, by running an infrastructure analytical tool which gathers infrastructure images in parallel with license plate detection. Analytics are applied, via a cloud based analytics engine, to provide detection of infrastructure anomalies, and prediction of potential infrastructure incidents. The system further generates a trigger alert warning of a potential infrastructure incident and recommendation to address the potential infrastructure incident.

Abstract: Adjustable license plate brackets for vehicles comprising a first bracket element that is secured to a vehicle; a second bracket element having an upper end to be connected to a license plate and a lower end disposed upon the first end of the first bracket element; and a third bracket element having an upper end to be connected to a license plate and a lower end disposed upon the second end of the first bracket element. The second bracket element and the third bracket element are configured to be connected to the first bracket element at a plurality of positions, implemented using an elongated aperture with a plurality of notches into which a bracket element connector can be inserted, respective so that a distance between the upper ends of the second and the third bracket elements varies to accommodate license plates with different sizes.
