An ultrasound system determines the presence of a foreign object in a container of fluid by measuring echo signals from the outer surface of the container and the inner surface of the container. The amplitude of the echo signals are compared to determine the presence of an object in the container. The system also determines viscosity of the contained fluid by measuring a through-transmission time through the container and the fluid, measuring an outer echo transmission time of an outer echo signal from the outer surface of the container and an inner echo transmission time of an inner echo signal from the inner surface of the container, and determining a time difference between the outer echo transmission time and the inner surface transmission time.

Real-time system for detecting foreign bodies in food containers using ultrasound

The disclosed invention uses two sensors to capture the heartbeat and environmental noises of an occupant of a vehicle or hospital bed. One of the sensors is placed on a seat or bed frame adjacent the occupant. A second sensor is placed remotely from the occupant, on a vehicle floor, or remote portion of the bed frame. A signal conditioning module is attached to the first and second sensors for detecting the heartbeat signal. Specialized software is used for processing the signal and decision making based upon the extracted heartbeat signal. The invention is capable of operating despite environmental noise and vibrations.
