Abstract: A blockage monitor for detecting a blockage in flow of particles includes a sensor body for mounting on a wall of the seed duct and defining a front face flush with the duct surface carrying both an LED light source for projecting light into the interior of the duct and a phototransistor arranged to produce an output signal proportional to the intensity of reflected light received which increases as a seed passes. A separate blockage module counts the output and uses an algorithm for comparing the count with a calibration count to determine whether there is a blockage of the duct. A power voltage is supplied to each sensor using two wires. A test of the sensor includes a pulse in the power voltage so as to generate a corresponding but delayed pulse in the light from the light source.

Abstract: Method and device for indicating movements of gas bubbles in a liquid, droplets of liquid in a gas or a level of liquid, the liquid or the gas forming a medium in a conduit (15) or a container. Microwave signals of a predetermined frequency are transmitted through a section (G) of the conduit (15) or the container (16) that is pervious to microwaves toward said medium, and microwave signals reflected from the medium are received. Received microwave signals are then utilized to indicate presence of gas bubbles, droplets, or a level of a liquid moving in said conduit (15) or said container (16).Said conduit (15) is designed with a section (G) that is pervious to microwaves, and a microwave transmitter (S) is provided to transmit microwave signals towards said section (G). A microwave receiver (M) is provided to receive microwave signals that are reflected from the medium, and said microwave receiver (M) is operatively connected to a detector (6).

Abstract: An arterial shunt is disclosed having means for indicating the flow of blood through the shunt. The shunt comprises a movable indicator element responsive to the flow of blood. Whether or not blood is flowing through the shunt may be quickly and easily ascertained by visual inspection of the indicator element through a transparent window. Alternatively, electromagnetic or optical means may be employed to measure the velocity of the movement of the indicator element which also allows the rate of blood flow through the shunt to be quantified.
