Abstract: The breastfeeding device to prevent baby suffocation includes a main unit and a remote unit. The main unit is mounted on a silicon pad or patch having an adhesive layer for attaching the main unit to one of the mother's breasts. The main unit includes a microcontroller having a sensor, such as a pressure sensor, connected thereto, either directly on the same printed circuit board or mounted external to the main unit and connected to the microcontroller by a wire or cable. The main unit has a transmitter mounted thereon for sending a signal to the remote unit when the sensor detects too much pressure being applied to the baby's mouth and nose. The remote unit has a receiver for receiving the signal, and a microcontroller for switching on an audible alarm when such a signal is received.

Abstract: A method of separating water from oil includes combining the oil with a magnetite powder to form a mixture and directing the mixture to a closed chamber having a plurality of magnetic field generating elements. The magnetic field generating elements generate a magnetic field sufficient to separate the magnetite powder and oil from water in the mixture, such that the water sinks to the bottom of the chamber. A valve at a lower end of the chamber can be opened to release the water collected at the bottom of the chamber. The method can be used to enhance the quality of crude oil by lowering the Bs &W content in the crude oil.
