Abstract: An example apparatus includes interface circuitry, machine-readable instructions, and at least one processor circuit to be programmed by the machine-readable instructions to identify crosstalk between a first signal via and a second signal via on a printed circuit board (PCB) layout, determine an area for placement of a ground via between the first signal via and the second signal via, and classify one or more regions of the PCB layout into at least one of a protective area or a non-protective area based on the area for placement of the ground via.

Abstract: An integrated, modular equipment system including a communication component configured to allow voice and data communication, a navigation component configured to provide location and directional information, a central processor in communication with the communication component and the navigation component, the central processor comprising software for providing information about a user's surroundings, and a power source operatively connected to the central processor. The central processor, communication component, navigation component, and power source of the system are integrated into a stock of a weapon.
