Abstract: Apparatuses and methods are provided for mitigating radio frequency interference and electromagnetic compatibility issues caused by the resonance of metal planes of a circuit board. A method for controlling impedance at an edge of a circuit board includes creating a cut at an edge of a plane of the circuit board. The cut extends from the edge of the plane to a point at a depth into the plane. The method can further include creating a cut pattern in the edge of the plane by repeating the cut along the edge of the plane such that an impedance of the plane at the depth is different, or lower, than an impedance of the plane at the edge of the plane. Other aspects are described.

Abstract: In certain embodiments, a sensing and tracking system detects objects, such as user input devices or peripherals, and user interactions with them. A representation of the objects and user interactions are then injected into the virtual reality environment. The representation can be an actual reality, augmented reality, virtual representation or any combination. For example, an actual keyboard can be injected, but with the keys pressed being enlarged and lighted.
