Abstract: Embodiments relate to a test method for testing an unpopulated printed circuit board. The method can involve the steps of: exposing the unpopulated printed circuit board to temperatures of a reflow soldering process in a first step; and testing the electrical connections of the unpopulated printed circuit board. Embodiments also relate to a test device and a method for producing populated printed circuit boards.

Abstract: The present invention relates to an implantable ultrasonic transducer comprising a first device for generating ultrasound, a second device for receiving ultrasound, and a circuit board, wherein the device for generating ultrasound is formed from a piezoelectric polymer, which is integrated in the circuit board. The invention also relates to a medical device which can be introduced into the body and comprises an ultrasonic transducer of this type.

Abstract: Cursor synchronization in a plurality of graphs. A plurality of graphs may be displayed. Each graph may visually represent data and may include at least two axis. User input may be received specifying a value of a first axis of a first graph of the plurality of graphs. The method may determine if the first axis in the first graph corresponds to a first axis of a second graph in response to the user input. A visual indication may be indicated at a second value in the second graph in response to determining that the first axis in the first graph corresponds to the first axis of the second graph. The second value may correspond to the first value.
