Abstract: The invention provides, in some aspects, a method of automated diagram generation that includes inputting a description of a plurality of entities and connectivity relationships in which those entities participate with one another; assigning the entities to each of one or more groups groups; assigning the entities to each of one or more columns, each of which has one or more lanes; determining a candidate layout of columns for placement into one or more workspaces based on widths assigned to those columns; assigning connectivity relationships of one or more entities in at least one column to each of one or more lanes based on the column(s) to which entities participating in those connectivity relationships are assigned; assigning widths to at least one of the columns as a function of those lane assignments; and outputting a representation of that candidate layout.

Abstract: A hydrogen fueled jet engine for hypersonic aircraft. The compressor of the jet engine is driven directly by a dual-acting rotary piston engine. Heated, high pressure hydrogen is delivered to the rotary piston engine for expansion therein. The crankshaft of the rotary piston engine is attached directly to the air compressor of the jet engine. The power from the expanding hydrogen drives the air compressor of the jet engine. After the hydrogen is expanded to produce power, the hydrogen is burned as fuel.

Abstract: A system and method for documenting critical tasks in a complex work environment using a computer to track the critical tasks from assignment to completion. The flow of accountability is tracked from the assignment of critical tasks to the completion and reporting of the performance of the tasks. The system creates a probe containing a set of mutually exclusive statements pertaining to a critical task, transmits the probe to field personnel, receives an input from the field personnel corresponding to a selected one of the mutually exclusive statements, receives a location identifying signal corresponding to a location of the field personnel when responding to the probe, and saves the input and the location identifying signal as a permanent transcript. The system reviews the transcript to determine whether certain alert codes are present, and then triggers predefined actions based on the presence of the alert codes.

The system creates a probe containing a set of mutually exclusive statements pertaining to a critical task, transmits the probe to field personnel, receives an input from the field personnel corresponding to a selected one of the mutually exclusive statements, and saves the input as a permanent transcript. The system reviews the transcript to determine whether certain alert codes are present, and then triggers predefined actions based on the presence of the alert codes. The system alerts other team members when expectations are not met, either because a scheduled input is not received, or because a condition is detected requiring management attention.
