A system includes an apparatus and a processor. The apparatus includes a set of actuator elements that move between two positions. Each actuator element is comprised in: exactly one first subset out of a plurality of non-empty first subsets and exactly one second subset out of a plurality of non-empty second subsets. The processor is configured to generate one or more control commands for a group of subsets out of the first and the second pluralities of subsets in response to a number of moving elements which, if released from the first extreme position during a second sampling cycle, enables production by the apparatus during the second sampling cycle of a sound.

Methods, apparatus, systems, and articles of manufacture are disclosed. An example system to modify an industrial control system includes: at least one memory; programmable circuitry; and instructions to cause the programmable circuitry to: configure a device driver based on a first command, the first command to configure the device driver to initiate a device-specific communication protocol to collect input data from a publisher device coupled to the device driver; access a second command from a subscriber device, the second command to include a device identifier of the publisher device and to specify at least one of a communication mode, a device calibration configuration, or a fault detection configuration, the second command based on a product quality prediction, the product quality prediction generated using a spectral data model; and provide the second command to the device driver.

An example includes at a first state: enabling a first source electrical current path corresponding to first source electrical current regulator circuitry in circuit with a first terminal to be coupled to a field device; and enabling a first sink electrical current path corresponding to first sink electrical current regulator circuitry in circuit with a second terminal to be coupled to the field device; at a second state, enabling a second sink electrical current path corresponding to second sink electrical current regulator circuitry in circuit with the second terminal; and at a third state, disabling the first sink electrical current path.
