Abstract: An optical device including a first layer of a total internal reflection (TIR) waveguide and a second layer of the TIR waveguide is disclosed. The second layer of the TIR waveguide may be coupled to the first layer. The second layer may include an output coupling device configured to reflect light toward an exit face of the TIR waveguide. The output coupling device may include one or more diffractive gratings. The optical device may also include an input coupling face disposed on a non-diffractive edge portion the first layer or the second layer or both the first and second layer. The input coupling face may be configured to receive image light. Another optical device may include an input coupling face disposed on a non-diffractive input coupling element. The non-diffractive input coupling element may be positioned in an optical path for directing the image light to the TIR waveguide.

Abstract: A holographic skew mirror has a reflective axis, or skew axis, that can be tilted with respect to its surface normal. Tilting the skew axis in two dimensions with respect to the surface normal expands the holographic skew mirror's possible field of view, e.g., to 60 or more. These additional angles can be accessed using an out-of-plane writing geometry with matched total internal grazing extension rotation (TIGER) prisms.

Abstract: A vaporizer device includes various modular components. The vaporizer device includes a first subassembly. The first subassembly includes a cartridge connector that secures a vaporizer cartridge to the vaporizer device and includes at least two receptacle contacts that electrically communicate with the vaporizer cartridge. The vaporizer device includes a second subassembly. The second subassembly includes a skeleton defining a rigid tray that retains at least a power source. The vaporizer device also includes a third subassembly. The third subassembly includes a plurality of charging contacts that supply power to the power source, and an end cap that encloses an end of the vaporizer device.

Abstract: A multi-fiber cable assembly includes a pigtail segments spliced to a trunk segment using multiple mass fusion splices. The splices are disposed within an encapsulation at a common axial location. A flexible conduit extends from one end of the encapsulation to protect bare fibers of the trunk segment. A protective sheath extends from the opposite end of the encapsulation to protect the pigtail segments. The conduit and sheath are axially fixed to the encapsulation.

Abstract: Optical systems for performing gaze tracking and imaging an external scene are disclosed. An example optical system may include light sources for emitting visible and non-visible light. The optical system may include a waveguide that is operatively coupled to the light sources. A volume holographic light coupling element may be disposed between the surfaces of the waveguide. The volume holographic light coupling element may include a grating medium and a first volume holographic grating structure within the grating medium. In some examples, the first volume holographic grating structure may be configured to reflect non-visible light of a first wavelength about a first reflective axis offset from a surface normal of the grating medium at a first incidence angle. The optical system may also include an optical filter. Another example optical system may include an imaging device that is configured to receive the light external to the optical system.

Abstract: An integrated computing system configuration system includes a computer-based system that when executed, receives component definitions associated with physical components that are to be configured in a portion of a first sub-system of a first customized integrated computing system. Using the received component definitions, the system generates the first sub-system definition, which can be combined with a second sub-system definition to form a first integrated computing system. The system may also combine the first sub-system definition with another second sub-system definitions to form a second customized integrated computing system definition that is different from the first customized integrated computing system definition.

Abstract: An exemplary system for manufacturing a decorated polycarbonate sheet can include a mold, which has a surface and a three-dimensional pattern formed on the surface, such that the three-dimensional pattern resembles a machined metal surface. A substrate can be configured to contact a curable photopolymer, such that the curable photopolymer forms a curable layup disposed between the substrate and the mold. A light source can be configured to cure the curable layup so as to form a cured layup. The mold can be configured to be separated from the cured layup, and the cured layup can have a decorative surface texture corresponding with the three-dimensional pattern, such that the decorative surface finish mirrors the three-dimensional pattern resembling the machined metal surface.

Abstract: A portable hydraulic fluid handler cart capable of transporting liquid storage containers and providing filtered fluid transfer. Quick-disconnect couplers at the cart and system adapters, along with replaceable filter cartridges, maintain fluid integrity at the system and serviced equipment. An electric motor, transfer pump, retractable extension cord and power control switch mount to the cart. Forks, rails and an adjustable clamp contain a liquid drum to the cart. A pair of handles and four wheels facilitate gripping, tipping and transport of drum containers. A kickstand stabilizes the cart when used alone. The filter media at the cart and adapters is selected to simultaneously filter liquid-borne and airborne particles and water from the fluid.
