A system and method for reducing laser communication terminal pointing uncertainty. The method trains an artificial neural network (ANN) with input data characterizing terminal pointing error and dependent parameters. The method inputs the trained ANN a set of data of these dependent parameters with unknown pointing error. The method uses the ANN output to apply corrections to the terminal pointing solution to reduce pointing uncertainty. The method can condition the ANN generated corrections to avoid cases where application of the ANN correction could exceed the original pointing uncertainty. This conditioning includes computing the Euclidean distance between current ANN input parameter values and values in the ANN training dataset, and bounding the allowed magnitude of the ANN pointing correction. The method can train the ANN incrementally during terminal operation for real-time updates or train the ANN offline with gathered data and implement the trained ANN on the terminal for subsequent links.

Method for creating an artificial facet

In a communications or jamming system, accurate timing for the control of the frequency, amplitude, modulation type, pulse repetition rate or other transmit characteristics is achieved for the transmission of digitally processed packetized signals through the use of standard non-realtime off-the-shelf components for the digital processing and a realtime interface which reads transmit chain headers and, with the assistance of a precise time reference, assures that the transmit chain is configured in time to transmit the packets. Note that the realtime interface assures nanosecond timing accuracy regardless of timing errors introduced by the off-the-shelf components used in upstream digital processing.

Method for real time control of transmit chain for software radios

In a communications or jamming system, accurate timing of the transmission of digitally processed signals is accomplished through the use of standard off-the-shelf components. In order to eliminate the need for high-cost, difficult to develop, specific digital hardware or realtime synchronous software not available from the standard off-the-shelf components, the output from the non-real time components is coupled to a realtime interface that assures nanosecond timing accuracy regardless of timing errors introduced by the off-the-shelf components. In one embodiment, the signals to be transmitted are digitized and then packetized, with the data to be transmitted reconstructed using non-real time digital processing. In order to establish the exact time for transmission, the packet is given a time stamp in the form of a header which indicates the exact time at which the packet is to be transmitted by the communications system, with the packet with header being transmitted to a storage buffer, the output of which is coupled to a realtime interface including a precise time output gate, the timing of which is controlled by a precision time reference having nano-second accuracy.

A reconfigurable distributed signal processing system uses an object-oriented component-framework architecture in which the system permits large-scale software reuse. This is accomplished by the use of a framework and a number of reusable, reconfigurable software components that are hardware independent.

A life preserver assembly includes a substantially planar main body portion formed from a buoyant material and separation means defining in said main body portion at least one life preserver. The separation means permits the life preserver to be removed from the main body portion. The life preserver is a unitary U shaped structure where the life preserver is preassembled for immediate use.

Life preserver assembly

A multi-level framework that allows an application to be developed independent of the chip or board, and any dependency is built in as part of the framework of the field programmable device (FPD). A shell configuration called a 'wrapper' has a standard look, feel and form factor that provides the interface between the high density language (HDL) application and a standardized and board independent HDL shell, thus isolating the HDL core. A second wrapper is a board specific HDL shell that interacts with the standardized shell. Any application that has the same look, feel and form factor has a common interface that allows various system boards to communicate, providing a mechanism for creating a HDL application component independent of the hardware. An outer shell binds the system to some board and talks to the application program interface (API) layer and the code layer to the outside world, such as the operating system.

A distributed processor architecture computer system and method that includes one or more processors and object oriented control program for real time and near-real time streaming data processing which is able to change the underlying communication mechanism at runtime, which includes the use of a software interface that hides the underlying communication mechanism. The present invention permits the accommodation of changes in communication resource availability due to link, equipment, or software failures or communication bandwidth resources being used by other collaborating programs. The ability to select a communication mechanism based upon cost performance for the particular program deployment and communication mechanism availability as described in the present invention. Typical criteria used for selecting different communication mechanisms for streaming a high volume data on each individual connection would include lower latency, lower overhead time per message, higher throughput in bytes per second of a particular computer, communication equipment and operating system independence.

The rod connecting member and bolt connecting member are rotatably engaged to one another. At least one interface washer is positioned over and between the rod connecting member and the bolt connecting member. Structure for creating a force between the rod, the rod connecting member, the washer, the bolt, and the bolt connecting member is provided. The interface washer has structure for engaging at least one of the rod and the rod connecting member, and for engaging at least one of the bolt and the bolt connecting member, so as to prevent relative rotation of the rod and the rod connecting member and the bolt and the bolt connecting member when the force is applied.

A fastener system includes an applicator for engagement by a tool, and a fastener such as a screw having a first surface with first screw threads in a one hand direction for engaging a workpiece. An attachment mechanism is provided to transfer rotational force from the applicator to the fastener and has second and third screw threads in an opposite hand direction to the first screw threads. The second and third screw threads are interfaced to establish a torque of the predefined magnitude prior to the fastener being attached to the workpiece. When the torque applied by the tool exceeds the predefined magnitude, the attachment mechanism begins to unthread and further application of torque from the tool to the fastener ceases, thereby controlling the applied torque to no greater than the predefined magnitude. The attachment mechanism can be used in a variety of applications including flush mounted heads, shallow aperture installations and multistage torque mountings.
