An analytics device for monitoring maintenance on an elevator system performed by an individual including: a processor; and a memory including computer-executable instructions that, when executed by the processor, cause the processor to perform operations, the operations including: capturing a first video stream using a first video camera; extracting sequences from at least the first video stream; extracting features from the sequences; and analyzing, using a long short-term memory model, the sequence to determine whether the maintenance performed on the elevator system by the individual is performed correctly.

Techniques for specifying and implementing programs. A graphical program is created in a graphical specification and constraint language that allows specification of a model of computation and explicit declaration of constraints in response to user input. The graphical program includes a specified model of computation, a plurality of interconnected functional blocks that visually indicate functionality of the graphical program in accordance with the specified model of computation, and specifications or constraints for the graphical program or at least one of the functional blocks in the graphical program. The specified model of computation and specifications or constraints are useable to analyze the graphical program or generate a program or simulation.

System and method for specifying and implementing programs. A graphical program is created in a graphical specification and constraint language that allows specification of a model of computation and explicit declaration of constraints in response to user input. The graphical program includes a specified model of computation, a plurality of interconnected functional blocks that visually indicate functionality of the graphical program in accordance with the specified model of computation, and specifications or constraints for the graphical program or at least one of the functional blocks in the graphical program. The specified model of computation and specifications or constraints are useable to analyze the graphical program or generate a program or simulation.

System and method for optimizing a data flow diagram based on access pattern information are described. Access pattern information for a data flow diagram may be received. The data flow diagram may include a plurality of interconnected actors, e.g., functional blocks, visually indicating functionality of the data flow diagram. The access pattern information may include one or more of: input pattern information specifying cycles on which tokens are consumed by at least one of the actors, or output pattern information specifying cycles on which tokens are produced by at least one of the actors. A program that implements the functionality of the data flow diagram may be generated based at least in part on the access pattern information.
