Abstract: An approach is disclosed herein for balancing layer densities in using an automated process. The approach disclosed herein operates on a region-by-region and layer-by-layer basis to perform parameterized layer balancing. In some embodiments, the process comprises determining densities of respective layers in respective regions, evaluating each layer and region to determine whether operations need to be taken to balance those layers in the corresponding regions, determining what those actions should be, and then implementing those actions. Additionally, in some embodiments, the process may operate in different orders and may be associated with a looping flow until a layout being processed has been balanced.

Abstract: Systems and methods of controlling outputs of infrared heaters used to join a first part to a second part, and a component made thereby. Upper and lower nests hold the first and second parts, respectively. A movable heating platen has infrared heaters on opposite surfaces. Imaging sensors have fields of view encompassing heated portions of the first and second parts, respectively, when the platen is retracted away from an area between the upper and lower nests. A controller causes the upper and lower nests to move while causing the platen to extend into and retract away from the area between the upper and lower nests. The first imaging sensor takes a first image of the heated portions of the first part, which causes an adjustment to be made to an output of the infrared heaters in a subsequent welding cycle.

Abstract: Example methods and systems are directed to simulating conditions for decision making. To help with decision making, simulated conditions may be used to generate probabilities of different events. Historical time-series data may be used to generate a probability distribution of values for simulated conditions. A user may be enabled to modify the probability distribution that was generated from the historical time-series data. The relationship between the value being simulated and other values may be represented by a knowledge graph. The knowledge graph may include nodes that represent arithmetic operations, input variables, external functions, database queries, and predictions. By running thousands of simulations with different values for input variables, as determined by the probability distributions for the input variables, a range of possible outcomes and their probabilities is generated. The simulation results are presented to a user to facilitate decision making.

Abstract: Examples of amplifiers use current-replication transistors and a separation circuit coupled to such transistors to separate error current components from other current components in a pre-driver of an amplifier. In response to driving the current-replication transistors with the separated error current components, replica base current components that approximate error-modulation components of the pre-driver base currents are generated. Replica-current subtraction circuitry coupled to the current-replication transistors then subtract the replica base current components from the pre-driver base currents, affecting cancellation of the error-modulation components of the pre-driver base currents.

Abstract: Examples of amplifiers accurately generate control currents for control terminals of output drivers using current-replication transistors and current mirrors. An input terminal of a first current mirror is coupled to the control terminal of a first current-replication transistor, and an input terminal of a second current mirror is coupled to the control terminal of a second current-replication transistor. The output terminals of the first and second current mirrors are coupled to the control terminals of first and second output drivers, respectively. First and second intermediate currents indicative of first and second currents flowing to the first and second output driver elements, respectively, are generated. Using the first and second current mirrors, first and second control currents are generated to control the first and second output driver elements, respectively, by scaling the first and second intermediate currents according to the gain factors of the current mirrors.
