Abstract: A soil sampling apparatus comprising a cylindrical body having an upper end, a lower end, and an egress aperture located along the cylindrical body proximal the lower end. The apparatus further includes a handle connected to the upper end of the cylindrical body for manual positioning and securing the apparatus while in use. The apparatus further includes a base plate with an aperture therein for receiving the cylindrical body at the lower end. The cylindrical body is secured to the base plate and extends a distance through the aperture of the base plate, thereby defining a probe. A shaft may be connected to an auger and positioned within the cylindrical body for upward and downward movement therein. A drill may be used for rotating the shaft and auger. The apparatus further includes a receptacle comprising an ingress aperture. The receptacle may be joined to the cylindrical body, the ingress aperture juxtaposed the egress aperture.

Abstract: A safety device for a motorcyclist by instantaneously inflating a suit constituting an air bag for cushioning the effects of a fall. Sensors (2, 3, 3a, 4, 5, 6) are connected to a microprocessor (1) which sends an inflation signal in the presence of certain operating parameters of the vehicle, and in particular when the motorcyclist is ejected.

Abstract: A vibratory drill head for use with a drill stand apparatus. The eccentric cams are mounted on parallel drive shafts which are powered by hydraulic motors. The hydraulic motors cause the drive shafts to spin in opposite directions. The counter-rotating eccentric cams eliminate horizontal vibration and maximize vertical vibration. The vibratory drill head is mounted to a drill shaft such as a sample tube. When the vibrating drill shaft is lowered into the soil, the vibrations allow the sample tube to pierce the soil to collect the sample. The minimization of horizontal vibration produces accurate core samples.
