Methods, apparatus, systems and articles of manufacture corresponding to a fan blade with intrinsic damping characteristics are disclosed. An example fan blade comprises an exterior body including a first side and a second side; a first hairpin structure in contact with (a) the first side of the exterior body and (b) the second side of the exterior body; and a second hairpin structure in contact with (a) the first side and (b) the second side, wherein the first hairpin structure and the second hairpin structure are made from different materials.

A drilling tool has an upstream drilling string, a downstream drilling bit, and a percussive device connected between the upstream drilling string and the downstream drilling bit. In a first state, the upstream drilling string is generated with elastic compression by the percussive device, and in a second state, the upstream drilling string releases the elastic compression to apply impacts on the downstream drilling bit through the percussive device. The drilling tool has a prolonged service life and can effectively reduce the drilling cost.

The disclosure relates to a computer-implemented method comprising inputting a representation of a 3D modeled object to an abstraction neural network which outputs a first set of a first number of first primitives fitting the 3D modeled object; and determining, from the first set, one or more second sets each of a respective second number of respective second primitives. The second number is lower than the first number. The determining includes initializing a third set of third primitives as the first set and performing one or more iterations, each comprising merging one or more subsets of third primitives together each into one respective single fourth primitive, to thereby obtain a fourth set of fourth primitives. Each iteration further comprises setting the third set of a next iteration as the fourth set of a current iteration and setting the one or more second sets as one or more obtained fourth sets.

A method for dynamically and automatically creating a three-dimensional (3D) model utilizing one or more two dimensional (2D) schematics corresponding to a project is disclosed. The method includes receiving the one or more two-dimensional (2D) schematics onto a first server application, utilizing a Building Information Modeling (BIM) 3D modeling program for the purpose of extracting location and/or position data for the project from the corresponding two-dimensional schematics, determination and classification of various objects from the corresponding 2D schematics, extracting a planar shape information for each of the objects wherein each of the planar shape information is utilized to determine a corresponding 3D shape/orientation of each of the objects, and combining the position data, the classification data and the orientation data into an extracted information file which is then converted to develop a 3D model corresponding to the 2D schematics.

A virtual build of an assembly may be performed by operating a virtual build tool inside of an active session of design software that is configured to design an assembly having multiple individual parts; importing characteristics of the assembly from a three-dimensional (3D) model of the assembly that is maintained by the design software; receiving an input of sequence numbers that indicate an assembly order for the individual parts; generating images for the individual parts as they are incrementally added to the assembly based on the sequence numbers; and generating a set of build instructions based on the sequence numbers and the images for the individual parts, where the set of build instructions illustrate how to physically manufacture the assembly.

An apparatus and methods are provided for a suppressor to be coupled with a muzzle end of a barrel of a firearm to reduce muzzle blast and muzzle flash. The suppressor comprises a housing having a proximal end and a distal end. A front portion within the housing comprises a series of cylindrical gas expansion chambers for attenuating the temperature and energy of propellant gases accompanying a projectile fired from the firearm. An annular gas expansion chamber surrounds the cylindrical gas expansion chambers and directs a portion of the propellant gases from a rear portion of the suppressor to peripheral vents disposed at the distal end. Lateral chambers within the rear portion deflect and rebound a portion of the propellant gases before passing them into the annular gas expansion chamber. Ledges within the annular gas expansion chamber direct the propellant gases distally through suppressor toward the peripheral vents.
