Abstract: A methodology is provided for transferring a file from a first entity to a second entity over a network. The methodology may include receiving a first one of a plurality of blocks at the second entity, receiving a second one of said plurality of blocks at the second entity, receiving a last one of the plurality of blocks at the second entity, and assembling the first one of the plurality of blocks and the second one of the plurality of blocks into a single file at the second entity after receiving the last one of the plurality of blocks.

Abstract: Systems and methods are provided for efficiently transferring a file between two entities. A client system includes a file partitioner that divides a file into a plurality of blocks. A client control application initiates a plurality of Transmission Control Protocol (TCP) connections. Each of the blocks is assigned to a TCP connection. Each block is transmitted via its assigned connection. A server system includes a server control application operative to monitor a plurality of TCP connections. The server receives a plurality of blocks via the TCP connections and writes the block to a file at the server system.

Abstract: A method and system are provided for billing usage over a network. This may include determining when a network interface is turned on and determining when the network interface is turned off. A time-based bill may be created based on when the network interface is turned on and when the network interface is turned off.

Abstract: A method is provided that includes viewing at least one frame of a video file at a first location, viewing the at least one frame of the video file at a second location and transmitting a command from the first location to the second location regarding a control operation of the video file.

Abstract: Apparatus, and a related method for its operation, for generating multiple parallel streams of data from a large solid-state mass storage device, under the individual control of multiple users requesting the data streams. The apparatus includes a hardware interface table containing a user command and current memory address for each active user requesting data from storage. Memory array addressing logic cycles through the hardware interface table and generates multiple streams of memory array addresses based on the user commands and the current memory addresses, but without using a processor to generate the addresses. The address streams are directed to a memory array, from which are output multiple streams of corresponding data. User commands for selective control of each data stream are converted to new memory addresses, which are stored in the hardware interface table and almost instantly result in performance of requested control functions with respect to the data streams.

Abstract: A modular solid-state mass data storage device providing high-density, high capacity storage of numerous full-length movies for video server applications. The mass data storage device employs a modular pipeline architecture in which a distributed array of controller/memory modules is arranged in parallel controller/memory channels on one or more controller/memory cards. The modular pipeline architecture, in which each controller/memory channel has multiple controller/memory modules connected in a serial chain by address, data and control buses, allows the number of controller/memory modules in each channel and the number of controller/memory channels to be selected to accommodate a desired storage size and transfer rate, without an undesirably high latency time. An asynchronous transfer mode (ATM) switch allows multiple viewers to access the movies stored in the mass data storage device with independent video cassette recorder (VCR)-like control of the movie being watched.

Abstract: A modular solid-state mass data storage device providing high-density, high-capacity storage of data employs a modular pipeline architecture in which a distributed array of controller/memory modules is arranged in parallel controller/memory channels on one or more controller/memory cards, each controller/memory channel having first and last controller/memory modules. The modular storage device also includes a data format module, and first and second busses connecting outputs of the data format module to inputs of each of the first and last controller/memory modules. The first bus also connects outputs of the last controller/memory module in each channel back to an input of the data format modules.

Abstract: A radiation-hard dynamic random access memory (DRAM) device having reduced sensitivity to single event upset and latchup. The radiation-hard DRAM device includes a high-density configuration of transistors that have undergone neutron bombardment. The high-density configuration of transistors reduces sensitivity to single event upset, but increases sensitivity to latchup. Neutron bombardment reduces the increased sensitivity to single event latchup to effectively provide permanent latchup immunity.

Abstract: A flight data recorder for reliable, high-speed storage of flight data employs a distributed, modular architecture in which an array of controller/memory modules is arranged in parallel controller/memory chains and the memory in the individual controller/memory modules is partitioned into submodules. This distributed architecture allows failed controller/memory modules or failed memory submodules to be bypassed, thus providing fault tolerances for both controller and memory functions. The modular architecture allows the number of controller/memory modules to be easily configured to accommodate any required storage size, while the number of parallel controller/memory chains can be configured to accommodate any required data rate.

Abstract: The present invention discloses a dual function satellite imaging and communication system (10, 40, 50, 60) using a solid state mass data storage device (30) which generates and stores image data at a relatively low data rate and subsequently transmits the data at a significantly higher data rate. The dual function imaging and communication system (10, 40, 50, 60), which may be incorporated as a body mounted payload of an imaging satellite, provides a single antenna or aperture (28, 54, 62) to perform both the imaging and communication functions and simplify the imaging and communication systems of the imaging satellite by eliminating the requirement for a separately gimballed antenna and/or aperture for each system. Further, the present invention is designed to operate in a low duty cycle mode to minimize its power supply requirements.
