A method for determining the location of a medical device within a body is provided. The method includes transmitting from the medical device an acoustic signal; receiving with the medical device a reflected acoustic signal; advancing the medical device based on a first algorithm, the first algorithm including a first weighting factor and a first feature extracted from the reflected acoustic signal; determining a first location of the medical device based on the first algorithm; and moving the medical device to a second location based on a second algorithm, the second algorithm based on the determined first location and including at least one of a second weighting factor and a second feature extracted from the reflected acoustic signal. Also disclosed are systems and devices for performing the methods described herein.

Described herein are systems, devices and methods to increase the accuracy of intravascular catheter placement, and to improve electrocardiogram (ECG), intravascular electrogram, and ultrasound Doppler signal processing to detect the Superior Vena Cava (SVC) area. Embodiments of the invention are intended to place an intravascular catheter within the lower ⅓ of SVC to the junction of the SVC and the right atrium (RA)—called the cavoatrial junction (CAJ). In particular, the improved accuracy of CAJ location detection during an intravascular catheter placement can be provided by optimization of ECG parameters and ultrasound Doppler signal using Neuro-Fuzzy logic and/or other processing techniques.

The present disclosure generally relates to printed circuit boards or printed circuit board assemblies for fiber optic communications. In one example, an optoelectronic assembly may include a printed circuit board including a laser-roughened area, at least one optoelectronic component coupled to a surface of the printed circuit board, and an optical component attached to the printed circuit board. The coupling area may be defined by the optical component contacting the printed circuit board, and the laser-roughened area may be positioned entirely within the coupling area defined by the optical component contacting the printed circuit board.

The present disclosure generally relates to printed circuit boards or printed circuit board assemblies for fiber optic communications. In one example, a method may include coupling at least one optoelectronic component to a surface of a printed circuit board. The method may include lasering the surface of the printed circuit board to form a laser-roughened area on the surface of the printed circuit board. The method may include coupling an optical component to the printed circuit board at the laser-roughened area on the surface of the printed circuit board.
