Abstract: A fan for providing thrust including at least one blade, a hub adapted to carry the at least one blade, a hub motor adapted to rotate the hub 360 degrees about a first axis extending perpendicular to the at least one blade, a first mount adapted to carry the hub, and a first mount motor adapted to rotate the hub 360 degrees about a second axis perpendicular to the first axis and extending through the first mount first and second side securing points. The first mount may include a first mount first side securing point adapted to pivotally carry the hub, and a first mount second side securing point adapted to pivotally carry the hub.

Abstract: The described embodiments concern verifying operation of a device, where the device may have one or more inputs and/or one or more outputs. At least one input and/or output is associated with an intelligent connector. An intelligent connector is a combination of a signal transport path and a data structure. The signal transport path may be electrical conductors leading to the device or a physical connector associated with the device. The data structure contains the name of a variable transported by the associated physical connector, an address of the variable itself as a value in memory, and further information of a source device that produces the variable, at least in the form of address or pointer to the source device data structure and the addresses of all destination devices that consume the variable.

The intelligent connector is a data structure that contains the name of a variable transported by that connector, an address of the variable itself as a value in memory, and further information of the device producing the variable, at least in the form of address or pointer to the device data structure and the addresses of all other devices consuming that variable.

Abstract: A technique for debugging of a signal processing program or model (or the debugging and reconciliation of two independent software instantiations). Timelines (Vectors) of signal values for verification are condensed to a small amount of information, easy to understand and manage. The information is stored in “Intelligent Points”, which can be graphically specified by the test engineering. The Intelligent Points can include one or more attributes that describe how to generate the appropriate signals. The information so stored can then be automatically expanded to complete timelines.

Abstract: A technique for debugging of a program model (or the debugging and reconciliation of two independent software model instantiations) with the perception of immediate showing of values assumed by all variables at any selected time, by permitting a user to move a selected test point in a forward and reverse direction along a time line, without recalculating the model each time the test point is moved. This is achieved by running the program model once and then saving all the variable values in memory, the values associated with the explicit name of the pertaining variable.
