Abstract: A parallel optical computing system is described, said system comprising: at least one first module (10) comprising at least one polarization filter (12) and at least one liquid crystal cell (13), the first module (10) being configured as an optical modulator (100) for receiving light from a light source (70) and for encoding the light output from the liquid crystal cell (13) into optical data to be processed; at least one second module (20) comprising at least one polarization filter (22) and at least one liquid crystal cell (23), the second module (20) being able to be configured as an optical processor (200) for receiving the optical data to be processed and for outputting an optical result of the processing; at least one optical detector (40), designed to receive the optical result of the processing and convert the optical result into a corresponding electrical result.

Abstract: An end-to-end system for the multimedia distribution over a Wi-Fi network uses a wireless multicast transmission mode that uses new communication protocols for high quality of service with many concurrent users; the system allows using Wi-Fi Access Points for media content streaming, without new hardware; the system handles automatic configuration, preparation, and management of all the network traffic in end-to-end mode; the multimedia contents can come from any source, including local or remote file servers, or captured live; the contents are directly received on the final clients' mobile devices using an application that configures the device for appropriate data reception; the multimedia streaming system are independent from the user's infrastructure. The system includes four main elements: One main broadcasting module; One automatic configuration module of the Wi-Fi network; One automatic configuration module for mobile applications; and One dashboard for modules control and configuration.
