Abstract: A computer system for part production using flow infill design receives a computer-aided design file that describes physical dimensions of a target object (120). The computer system identifies a physical boundary portion (300) of the target object within the CAD file. The computer system generates a first tool path to additively manufacture the physical boundary portion (300). Additionally, the computer system sends instructions to a computer system in communication with a dispenser (130) that cause the dispenser to implement the first tool path while dispensing a boundary material. Further, the computer system generates a command to dispense the coreactive infill material (310) within the physical boundary portion.

Abstract: An integrated circuit device includes a package and at least two leads exposed external to the package to permit electrical connections to the package. A first die situated in the package has a first substrate and at least a first terminal electrically coupled to a first one of the leads. A second die situated in the package has a second substrate and at least a second terminal electrically coupled to a second one of the lead. An adhesive material holding the first and second die in place forms a voltage-triggered conduction path between the first and second die electrically that isolates the second die from the first die under a first condition and provides an ESD current path between the first one of the leads and the second one of the leads under a second condition.

Abstract: Examples for graph database query classification include receiving a graph query and determining if the graph query matches benchmark data. In the event that the graph query does not match benchmark data, the query may be parsed, a canonical internal representation of the query may be determined, the representation may be mapped to a rule, and the query may be classified based on the rule. In the event that the confidence score for the query classification does not exceed a threshold, the query may be sent to a synthetic graph or synopsis for simulation. In some examples, the simulation may include selecting computationally expensive graph operators in the query for simulation.
