Nose cone comprising electronic circuit boards arranged radially

An electronic circuit board arrangement, comprising:

• a plurality of electronic circuit boards;
• and
• a control board,
• wherein the electronic circuit boards are reversibly connected to the control board and are arranged along a longest dimension of the electronic circuit boards at an axis substantially perpendicular to the control board, and further arranged such that the electronic circuit boards extend radially inwardly to a center of the control board, and
• wherein the electronic circuit boards are reversibly engaged with the control board via a push-fit arrangement, the push-fit arrangement comprising a co-operative guide pin and recess arrangement.

An assembly comprising:

• a transducer housing comprising a first surface and a second surface;
• a transmission assembly reversibly operably connected to the first surface of said transducer housing, said transmission assembly comprising a control board and a plurality of electronic circuit boards, each of said electronic circuit boards being reversibly connected to the control board and being arranged along a longest dimension of the electronic circuit boards at an axis substantially perpendicular to the control board, and further arranged such that the electronic circuit boards extend radially inwardly to a center of the control board;
• and
• a transducer array operably linked to the transmission assembly, and operably connected to the transducer housing, wherein the transducer array is mounted to the second surface of the transducer housing.
