A server may identify at least one token within the user input, and if it matches a conversation context data associated in a database with the at least one token: suspend execution of the first software instruction; identify an abstract node associated in the database with the conversation context data; identify a specialized node associated in the database with conversation context data and the abstract node; and execute a second software instruction within the specialized node.

Abstract: Techniques are described for calibrating an optical system in an additive fabrication device using an image of the build surface within the device. These techniques allow calibration to be performed by imaging one or more calibration features generated on (or at) the build surface, which may include illuminated regions of the build surface, regions of the build surface on which solid material has been formed, and/or regions of the build surface to which energy has otherwise been directed thereby making those regions distinguishable from their surroundings. The calibration features may be produced (at least in part) by the optical system to be calibrated. The location of the calibration features within the image may be compared with the intended location of these calibration features, and corrections to the optical system determined based on any differences between the actual and intended locations.

Abstract: The present disclosure provides for a system ensuring the integrity of received data. The system includes a processor, a trusted platform module, and a memory storing instructions. Upon a request from the processor, the trusted platform module generates an asymmetric key pair including a private key and a public key. The trusted platform module provides the public key and an encrypted private key to the processor. The processor generates a checksum of received content data and sends the checksum to the trusted platform module. The processor also loads the encrypted private key into the trusted platform module. The trusted platform module decrypts the encrypted private key, encrypts the checksum with the private key, and provides the encrypted checksum to the processor. The processor sends the content data together with the encrypted checksum to an external device. The external device may decrypt the encrypted checksum with the public key.

Abstract: Techniques are described for consistently moving powder from a hopper into a trough for subsequent delivery into a build area of an additive fabrication system. A powder delivery apparatus may comprise a hopper, a trough, and a doser. The doser may be configured to rotate about an axis and may include a recess that, when the doser is rotated about the axis, travels into and out of the hopper and into and out of the trough. As a result, when powder is present in the hopper, the recess may carry powder from the hopper to the trough when the doser rotates. The trough and doser may be configured so that when the trough contains the desired amount of powder for recoating, the doser does not transfer additional material from the hopper into the trough. As a result, the amount of powder in the trough may be self-regulating.

Abstract: A packet is received by a hypervisor from a first virtualized execution environment, the packet to be provided to a second virtualized execution environment. It is then determined whether the packet was successfully delivered to the second virtualized execution environment. In response to determining that the packet was not successfully delivered to the second virtualized execution environment, a network policy is identified that indicates whether to subsequently provide the packet to the virtualized execution environment. In response to the network policy indicating that the packet is to be subsequently provided, the packet is provided to the virtualized execution environment again.
