A method for optimizing performance of an apparatus includes interrogating at least one part of the apparatus to obtain information about the at least one part. Once the at least one part is interrogated, instructions for optimizing at least one operation of the apparatus is determined based on the obtained information about the at least one part. Next, the instructions are applied to the at least one operation of the apparatus to optimize the performance.

A configurable self-identifying workpiece transport system is described for moving an associated workpiece relative to a plurality of associated workpiece functional units selectively performing operations on the associated workpiece. The transport system includes a plurality of transport modules and a control unit. The plurality of transport modules are disposed in selected positions relative to the associated workpiece functional units, and each of the plurality of transport modules stores identification data and functionality data specific to the transport module. The control unit includes an automatic identification system in communication with each of the plurality of transport modules for retrieving the identification data and the functionality data from each of the plurality of transport modules and generating an itinerary for moving the associated workpiece relative to the workpiece functional units. Each of the plurality of transport modules includes a local communication circuit adapted to selectively communicate with adjacent transport modules. In one embodiment, the control unit is distributed among the plurality of transport modules and in another embodiment, a global system bus is provided by a central control unit for communicating with each of the plurality of transport modules through the global bus. The local communication circuit includes photo optic devices and the global system bus uses a two wire interface.

A system for the secure physical attachment of a second device to a first device is disclosed comprising a first and second inter-connection attachment means in physical association with each device. The second inter-connection attachment means physically mates with its corresponding first inter-connection attachment means. Additionally, means for detecting the physical mating of each of the first and second inter-connection attachment means is provided. The detecting means is preferably associated with at least one of the devices and in communication with each of it's associated device's inter-connection attachment means. Means are provided for determining that the first and second inter-connection attachment means have been securely mated and, if not, means are provided for indicating the status of the completion of the secure attachment there between. A controller is used for halting at least one of the devices in the event that the attachment there between has not been secured and for receiving additional instructions from an end-user.

A system is disclosed for use in additively manufacturing a structure. The system may include an additive manufacturing machine, a memory having computer-executable instructions stored thereon, and a processor. The processor may be configured to execute the computer-executable instructions to determine if a tool path to be followed by the additive manufacturing machine during manufacture of the structure is located in free-space or on top of another tool path. When the tool path is located in free-space, the processor may be further configured to execute the computer-executable instructions to make a determination regarding a curvature of the tool path, and to selectively cause the additive manufacturing machine to fabricate a support for the tool path based on the determination.

A system is disclosed for use in additively manufacturing a structure. The system may include an additive manufacturing machine, a memory having computer-executable instructions stored thereon, and a processor. The processor may be configured to execute the computer-executable instructions to cause the additive manufacturing machine to discharge a path of composite material, including a continuous fiber and a matrix at least partially coating the continuous fiber. The processor may also be configured to execute the computer-executable instructions to monitor an energy level within the continuous fiber during discharging, to make a determination that the continuous fiber has lost continuity based on a reduction in the energy level, and to selectively interrupt the discharging based on the determination.

Techniques for improving flexural strength in 3D-printed object. The techniques generally include identifying a portion of a 3D model corresponding to the 3D-printed object to which one or more support posts should be added and adding support post descriptors to the 3D model within such a portion. The support post descriptor defines a position and at least one dimension of a support post cavity and a position and at least one dimension of a support post, both having a height corresponding to at least two layers of 3D-printable material. The model, including the support post descriptors are transmitted to a 3D printer to print the 3D model, which includes a support post cavity and a support post having a height of at least two layers.
