Abstract: Exemplary subpixel structures include a directional light-emitting diode structure characterized by a full-width-half-maximum (FWHM) of emitted light having a divergence angle of less than or about 10°. The subpixel structure further includes a lens positioned a first distance from the light-emitting diode structure, where the lens is shaped to focus the emitted light from the light-emitting diode structure. The subpixel structure still further includes a patterned light absorption barrier positioned a second distance from the lens. The patterned light absorption barrier defines an opening in the barrier, and the focal point of the light focused by the lens is positioned within the opening. The subpixels structures may be incorporated into a pixel structure, and pixel structures may be incorporated into a display that is free of a polarizer layer.

Abstract: The present disclosure is generally related to 3D imaging capable OLED displays. A light field display comprises an array of 3D light field pixels, each of which comprises an array of corrugated OLED pixels, a metasurface layer disposed adjacent to the array of 3D light field pixels, and a plurality of median layers disposed between the metasurface layer and the corrugated OLED pixels. Each of the corrugated OLED pixels comprises primary or non-primary color subpixels, and produces a different view of an image through the median layers to the metasurface to form a 3D image. The corrugated OLED pixels combined with a cavity effect reduce a divergence of emitted light to enable effective beam direction manipulation by the metasurface. The metasurface having a higher refractive index and a smaller filling factor enables the deflection and direction of the emitted light from the corrugated OLED pixels to be well controlled.

Abstract: Computer technology for use in a computer system including a database system including a database management sub-system, a primary database and a secondary database, with the secondary database being maintained at least approximately in synchronization with the primary database over time as changes are made to data of the primary database (for example, a database system that includes disaster recovery (DR) features). A statistics update is performed first on a standby database to determine whether query efficiency and/or query optimization really will be substantially improved by performance of the statistics update. If not, then statistics update on the primary database is postponed until a future time.

Abstract: Techniques for audio tagging of an object of interest are provided. An object of interest within a field of view of a first video camera may be identified at a first time. At least one audio tag representing a first sound created by the object of interest may be generated and associated with the object of interest.

An audio tag representing the second tag may be generated. It may be determined that the object of interest and the unidentified object of interest are the same when the audio tag representing the first sound and the second sound are the same.

Abstract: A method of operating a talk group server to control a virtual talk group member. During operation, the talk group server determines an assignment for a virtual talk group member to join a first talk group and communicate on behalf of a talk group member associated with a second talk group. The talk group server obtains user profile associated with the talk group member and causes the virtual talk group member to join the first talk group using the user profile associated with the talk group member. The talk group server then controls the virtual talk group member to perform the assignment by generating audio communications as a function of the user profile associated with the talk group member and transmitting audio communications on the first talk group.
