Abstract: Provided is a method for masking a sensitive signal by injecting noise into planes of a printed circuit board (PCB). The method comprises detecting, by a secondary integrated circuit (IC), a noise signal on a shared plane of a PCB that includes the secondary IC. The noise signal may be analyzed to determine the characteristics of the noise signal. A masking signal may be generated based on the characteristics. The masking signal may then be injected onto the shared plane.

Abstract: Fabrication of a circuit board is facilitated by automatically determining an optimized power plane shape for a power plane of the circuit board, including ascertaining for the power plane a source location(s) and a sink location(s), where the source supplies power to the sink across the power plane. A center of current density is determined for the power plane shape, and a respective power plane sub-shape is incrementally generated between the center of current density and each source and sink location to, in part, supply a desired operational voltage from the source location(s) to the sink location(s) across the power plane. The respective power plane sub-shapes are combined into the optimized power plane shape. Further, the process includes initiating fabricating of the circuit board using, at least in part, the optimized power plane shape to provide the power plane shape within the circuit board.

Abstract: An apparatus and method for detecting transient voltage at an electrical component of a circuit board is provided. The apparatus including a circuit including a comparator and a latch, wherein a first input of the comparator is electrically coupled to the electrical component, and the comparator receives a threshold voltage at a second input, where the comparator outputs either a high signal or a low signal in response to both the first input and the second input, and an output of the comparator is electrically coupled to an input of the latch such that the latch outputs a high signal in response to receiving a high signal from the comparator, and an indicator electrically coupled to an output of the latch, and where the apparatus is mounted non-permanently to the circuit board to provide a non-permanent electrical coupling between the comparator and the electrical component.

Abstract: A displacement sensor that includes a stationary printed circuit board which includes a first capacitor pad, an indicator, and a battery electrically communicating with the first capacitor pad and the indicator and a sliding card which includes a second capacitor pad, the first capacitor pad and the second capacitor pad being orientated to face each other and in an overlapping relation to each other. An overlap being defined by the first capacitor pad and the second capacitor pad, wherein the overlap of the first capacitor pad and the second capacitor pad generates a capacitance, the generated capacitance changes as the sliding card moves as a result of a change in the overlap of the first capacitor pad and the second capacitor pad. The indicator is activated when the generated capacitance change reaches a threshold value.

Abstract: One aspect includes identifying via groups that each includes a ratio of a plurality of signal vias to one ground via based on a design file defining a layout of a multi-layer circuit board. A genetic via placement solver iteratively evaluates potential placement solutions that adjust a placement of one or more of the signal vias until at least one solution is identified that meets one or more placement criteria of the signal vias. The genetic via placement solver performs a mutation and recombination of one or more solutions that do not meet the one or more placement criteria and re-evaluates the one or more solutions that do not meet the one or more placement criteria. The design file is modified to include at least one shifted signal via position based on identifying the at least one solution that meets the one or more placement criteria.
