20090084168 | PROTOCOL FOR CHARACTERIZING ROCK, METHOD FOR CHARACTERIZING ROCK HARDNESS AND METHODS FOR USE THEREWITH - A protocol for characterizing a rock is provided. The protocol includes a crushing operation, wherein a test column of the rock in granular form is subjected to a compressive force orientated parallel to the axis of the column. The protocol further includes a measurement operation, wherein the amount by which the axial length of the test column is reduced through the application of the force is measured. The protocol yet further includes a calculation operation, wherein a characteristic of the rock is calculated using the product of the force applied and the amount by which the length of the test column is reduced through the application of the force. A method for characterizing the hardness of a subject rock is also provided. | 04-02-2009 |
20100281962 | ALL ELECTRIC PIEZOELECTRIC FINGER SENSOR (PEFS) FOR SOFT MATERIAL STIFFNESS MEASUREMENT - A PEFS (Piezoelectric Finger Sensor) acts as an “electronic finger” capable of accurately and non-destructively measuring both the Young's compression modulus and shear modulus of tissues with gentle touches to the surface. The PEFS measures both the Young's compression modulus and shear modulus variations in tissue generating a less than one-millimeter spatial resolution up to a depth of several centimeters. This offers great potential for in-vivo early detection of diseases. A portable hand-held device is also disclosed. The PEF offers superior sensitivity. | 11-11-2010 |

20130019665 | Testing of Concrete Using Existing Voids Within Concrete - A penetration head and related apparatuses are placed within a void to measure the in-place compressive strength of the surrounding material. An electronic load cell is attached to the penetration head and is forced against an opposite side of the void. A hydraulic ram or other device is connected between the penetration head and load cell. As the hydraulic ram pushes the penetration head and load cell in opposite directions and into the interior walls of the void, penetration depth is measured and mapped to load and material hardness is derived. | 01-24-2013 |
