Abstract
Apparatus for probing, sensing, testing penetrating and sampling a medium generally includes an actuator () for generating vibrations at ultrasonic frequencies and a horn () coupled to the actuator () for amplifying the actuator vibrations along with a non-rotating coring and drilling bit () for penetrating the medium. A bit () includes a drill stem () attached to the horn () and a bore () extends through the bit (), horn () and actuator () for withdrawal of samples. A free mass () is disposed between the horn () and the drill stem () for oscillating therebetween in response to the actuator vibration for causing migration of medium debris around and through the actuator bore for effectively self-cleaning of the bit (). The hammering action of the free mass () is used for penetration of the medium and for analysis of the medium though the use of spaced apart accelerometers (and).
