System and method to prevent cross-talk between a transmitter and a receiver
First Claim
1. A method comprising:
- mounting a transmitting device and a receiving device on a substrate, wherein the substrate includes a layer that blocks waves emitted from the transmitting device, and wherein the transmitting device and the receiving device are mounted in an area defined by the layer;
manipulating a structure to form a first compartment for the transmitting device and a second compartment for the receiving device, wherein the compartments are separated by a common wall, and wherein each compartment is continuous with at least part of the common wall; and
mounting the structure on the substrate.

Abstract
According to at least one embodiment of the invention, a method includes mounting a transmitting device and a receiving device on a circuit board, wherein the circuit board includes a layer that blocks waves (e.g., light waves) emitted from the transmitting device, and wherein the transmitting device and the receiving device are mounted in an area defined by the layer. The method further includes manipulating a structure to form a first compartment for the transmitting device and a second compartment for the receiving device, wherein the compartments are separated by a common wall such that each compartment is continuous with at least part of the common wall. The method further comprises mounting the structure on the circuit board. According to this embodiment, the transmitter and the receiver may be part of a proximity sensor, and the layer that blocks waves, the first and second compartments, and the common wall (which may be a folded double wall) operate to prevent cross-talk between the transmitter and the receiver.
