Abstract: Systems, methods, and apparatus for communication utilizing a plurality of time slots over at least one channel are disclosed. In one or more embodiments, the disclosed method involves assigning, by at least one processor, at least one of the plurality of time slots for media data. In one or more embodiments, at least one of the plurality of time slots assigned for the media data is periodic. The method further involves assigning, by at least one processor, at least one of remaining time slots of the plurality of time slots for non-media data. In at least one embodiment, the assigning of at least one of the plurality of time slots for the media data has precedence over the assigning of the remaining time slots of the plurality of time slots for the non-media data.

Abstract: Methods and systems for allocating resources in a wireless network are described. In one implementation, a wireless network is utilized by at least a first radio and a second radio. The wireless network includes at least a first channel and a second channel. The first channel is partitioned into control slots and data slots and the second channel is partitioned into at least data slots. The method includes transmitting, using the first radio, in a first control slot of the first channel, a first control signal comprising information for data slot negotiation. The method additionally includes concurrently transmitting or receiving, using the first radio, at least one of a first data signal or a second control signal on the second channel.

Abstract: A wireless communications system comprising a wireless communications unit. The wireless communications unit comprises a communications device, a back-end router, a cryptographic module connected to the back-end router, and a front-end router connected to the cryptographic module and the communications device. The communications device is configured to exchange information over a single wireless communications channel. The front-end router is configured to perform at least one of sending a first data packet received at the front-end router from the communications device to the back-end router through the cryptographic module and sending a second data packet received at the front-end router from the back-end router through the cryptographic module to the communications device.

Abstract: Systems and methods for distributed database management are disclosed. In an embodiment, a method of accessing information in a distributed database system having one or more data servers includes establishing a plurality of lattice structures configured to store data elements having inter-related information. A data query initiated by a client is then formulated that includes selected data attributes. The data query is processed to generate a query product, and the plurality of lattice structures are searched to identify data elements corresponding to elements in the query product. Pertinent data files located within another data server are accessed that correspond to the data query and generating a result, and the result is transferred to the initiating client system.

Abstract: An optical system (100, 200, 400, 500) that projects a real image (140, 412, 504) into space and includes one or more features located along the optical path that enhance the viewability of the real image. The optical system includes a converging element (128, 208, 416, 528) for converging a portion of source light (104, 516) so as to form the real image. One viewability-enhancing features is the use of a broadband reflector-polarizer (124, 208, 408, 532) having high transmitting and reflecting efficiencies. Another viewability-enhancing features is the use of polarizing elements (116, 124, 136, 408, 420, 424) having substantially matched bandwidth responses and/or comprising an achromatic design. An additional viewability-enhancing feature is the use of a wide-view film (144) to increase the viewing angle of the image.
