Abstract: A method for hierarchical work scheduling includes consuming a work item at a first scheduling domain having a local scheduler circuit and one or more workgroup processing elements. Consuming the work item produces a set of new work items. Subsequently, the local scheduler circuit distributes at least one new work item of the set of new work items to be executed locally at the first scheduling domain. If the local scheduler circuit of the first scheduling domain determines that the set of new work items includes one or more work items that would overload the first scheduling domain with work if scheduled for local execution, those work items are distributed to the next higher-level scheduler circuit in a scheduling domain hierarchy for redistribution to one or more other scheduling domains.

Abstract: A method is provided for compressing a binary geometry file for a structural product. The method includes accessing the binary geometry file that contains a geometric model of a structural product that is formed of component parts, the geometric model including an assembly of geometric models of instances of the component parts. The method includes identifying the component parts of the structural product, and generating a master binary geometry file for the structural product that contains geometric models of the component parts. The method includes applying the binary geometry file to a coder that generates a corresponding compressed binary geometry file. The coder searches the binary geometry file for the geometric models of the instances of the component parts, and substitutes references to respective ones of the geometric models of the component parts in the master binary geometry file.

Abstract: A method is provided for reconfiguring a vehicle for transfer from a first operator to a second operator. The method includes accessing first datasets that define an initial configuration of the vehicle, importing second datasets that describe maintenance, repair or service of the vehicle during in-service operation with the first operator, and generating a first composite dataset defining a current configuration of the vehicle. The method also includes accessing third datasets that define requirements of the vehicle for in-service operation with the second operator, and generating a second composite dataset that defines a target configuration of the vehicle from the first composite dataset and based on data of the third datasets.

Abstract: A drive axle system having a one-way freewheel clutch. The one-way freewheel clutch is configured to transmit torque between first and second axle assembles when an interaxle differential unit is unlocked. The one-way freewheel clutch transmits torque to one of the first axle assembly and the second axle assembly when the interaxle differential unit is locked.

Abstract: A differential assembly that may be provided with an axle assembly. The differential assembly may have a case that may have a first case portion and a second case portion. The first case portion may have a retainer pin hole that may receive a retainer pin that couples a spider shaft to the first case portion. The second case portion may inhibit removal of the retainer pin from the retainer pin hole.

Abstract: A method of controlling an axle assembly. At least one wheel hub may be operatively connected to a differential assembly having a ring gear when the ring gear does not receive torque from a torque source. Torque from the wheel hub may rotate the ring gear and the ring gear may provide splash lubrication.

Abstract: Systems and methods for creating airplane interior modification packages and associated proposals. The method for creating modification packages comprises the following steps: (a) interacting with a user interface presented on a display screen to select a specific airplane type and a specific airplane of the specific airplane type, which specific airplane has an initial interior configuration; (b) interacting with the user interface to select parts to be removed from and parts to be added to the initial interior configuration of the specific airplane to create a modified interior configuration; (c) extracting change results data identifying parts selected for removal and parts selected for addition; (d) creating a modification package that includes drawings and documentation relevant to removing or adding the parts identified by the change results data; and (e) delivering the modification package to an authorized party associated with the specific airplane.

Abstract: Example computing systems perform functions for calculating a sum representing a value of a system component or a structural component of an aircraft. The functions may include identifying the component for analysis and assigning numerical ratings that pertain to how the component relates to respective criteria. The criteria may include one or more of whether the component is described in an illustrated parts catalog, a reorder lead time, a component class, a price, whether repairing or replacing the component requires taking an aircraft out of service, a quantity of repair authorizations that have been issued for the component, or a quantity of communications regarding the component. The functions may further include calculating a sum of the assigned ratings and, based on determining that the sum exceeds (or is less than) a threshold value, initiating (or ceasing) a process to retrieve or curate one or more instances of the component.
