    摘要: The present invention relates to a target having conductive fibres in a plurality of beds into which a transmitting/receiving projectile may be embedded with a portion of the projectile remaining protruding from the target. Each bed indicates a score and is electronically insulated from the other. In some embodiments the separate scoring portions of the target transmit different signals with the signal from the projectile embedded in that portion of the target being radiated at a greater strength. The strongest signal (indicative of the portion of the target struck) is received by a nearby receiver and the score displayed. An alternative embodiment utilizes an externally transmitted signal and the projectile acts as a receiving antenna, conveying the signal to only that target bed in which the projectile is embedded and the individual beds are connected to the scoring display system.

    摘要: An apparatus for transmitting acoustic ultrasonic pulses and for receiving "echos" of the transmitted pulses, comprises a housing, an upstanding wall mounted on the housing defining the mouth of a well, and a transducer mounted in the housing so that the operative part of the transducer is located in the well. The well is substantially watertight and is provided with a jet for introducing water or other fluids to the well, or is pre-filled with fluid.
