A new, reliable and inherently safe nasogastric feeding tube position determination system has been developed. The system is particularly useful for preterm born infants. The system uses low-frequency transmit, reflection and receive coils. Transmit and receive coils are positioned in a handheld detection module in such a way that the mutual coupling is minimized, resulting in a good spatial resolution...
A need exists for small devices, capable of simultaneously receiving data an power. Through connecting one or more Schottky diodes in parallel to a small loop antenna and further employing a capacitor it is possible to receive data and DC power simultaneously. Through using analytical equations the device may be optimized for data and/or power reception.
