Abstract: A high intensity focused ultrasound (HIFU) transducer comprising a piezoelectric array with a layer of piezoelectric material having a patient-facing front surface and a back surface, the front surface comprising a transmitting surface, and a plurality of electrodes located on the front and back surfaces of the piezoelectric material for applying electrical signals to the piezoelectric array. Electrical connections between an electrode on the back surface to an electrode on the front surface of the piezoelectric array are made through non-magnetic conductive vias extending through the layer of piezoelectric material.

Abstract: A coolant flow control system (100, 200) includes an integrated coolant flow control and heat exchange device (10, 50). The device includes a valve body part (20, 60) and a heat exchange part (30, 70). According to the system, all the coolant flow from the engine is delivered back to the engine after passing through the valve body part (20, 60) and then the heat exchange part (30, 70) in which it passes over the heat exchanger part (40, 80). The valve body part (20, 60) by positioning of the coolant flow wall (26, 66) allows multiple flow modes and coolant paths to branch out (or converge) from (or to) thereby controlling the flow in all coolant circuit branches.

Abstract: An integrated heat exchange and fluid control device is provided having an inlet, a valve, a heat exchange section in fluid connection with the valve, a bypass section in fluid connection with the valve, and an outlet section in fluid communication with the bypass section and the heat exchange section. The valve is configured to distribute flow of the coolant into the heat exchange system and/or the bypass section. In the heat exchange sections, coolant is substantially cooled by a second fluid or airflow. In the bypass section, the coolant is substantially prevented from being cooled by the second fluid or airflow.
