Abstract: An apparatus (10) for assisting a player playing golf is disclosed. The apparatus includes a club connector (14) for connecting part of the apparatus to a golf club. This part includes an accelerometer (22) and a processor (24) for processing the signals from the accelerometer. There is also a body connector (46) for connecting a second part (42) of the apparatus to the body of the golfer. This second part also includes an accelerometer. The two accelerometers are used to determine the angle the club to the horizontal, the rotational angle of the head of the club, the angle of the player's spine to the horizontal and the club to spine angle. These angles are output to a display (32) on the part of the apparatus attached to the club.

Abstract: A surgical probe having the ability to thermally insulate adjacent healthy tissue from cooling or heating effects at adjacent tissue being subjected to thermal destruction by cryosurgery, electrosurgery and hyperthermia. The probe includes a spatula shaped thermally insulating member that is mounted at the distal end of an elongated rigid member of a width sized for insertion through a small cutaneous incision. The insulating spatula is of a material transparent to ultrasound thus allowing ultrasonic imaging of tissue through the thermal insulator without substantial image deterioration.
