Abstract: The present disclosure is generally related to LED packages with integrated light polarizers, for example, for generating 3D images. Some aspects are generally directed to having a light polarizer directly integrated within the LED package, for instance, without air between the light polarizer and the LEDs of each pixel and/or such that a relatively opaque side wall may surround the light polarizer. In some cases, direct integration of the light polarizer may minimize stray light between pixels to improve contrast ratio and/or image quality of the LED package. In some embodiments, the LED packages with integrated light polarizers are constructed such that every other pixel of the LED package emits left circularly polarized light, and the remaining pixels emit right circularly polarized light. Other aspects are related to methods of making and/or using the LED packages, or the like.

Abstract: Communications service programs (e.g., packet-switched phone and conferencing software with recordings and voicemail) are enabled to process user data files using custom encryption methods, where the existing service programs should migrate to work with the encrypted data files. A framework is introduced between application and system layer for replacing the major file routines to apply user file encryption routines in a manner that is transparent for existing service programs without requiring re-compiling.
