Abstract: A measurement system and method for determining a depth of penetration of a working portion of a surgical instrument (e.g., a rotating drill bit in a bore). A first sensor outputs a first signal representative of a displacement of the leading edge of the drill bit in the bore. A second sensor outputs a second signal representative of a force applied to the leading edge of the drill bit. A processor outputs a third signal representative of the depth of penetration of the leading edge of the drill bit when the leading edge of the drill bit passes from a first medium having a first density to a second medium having a second density. The third signal is based on the first and second signals.

Abstract: Methods are provided for predicting the properties of an asphalt fraction that contains two or more asphalt components based on measurements of the viscosity for the asphalt fraction. Based on the measured viscosity, a virtual cut point is determined for a virtual asphalt blend that has the same viscosity (to within a tolerance value) as the measured viscosity for the asphalt fraction. The virtual cut point is then used to determine a variety of predicted property values for the asphalt fraction. Optionally, the predicted property values can be used to adjust the actual cut point for the distillation or separation process used for forming the asphalt fraction.

Abstract: An apparatus generates a machine operation enable signal as a function of a closed position of a movable safety access door of a safety guard for a work cell. A pivotal plate carries a handle and a switch receiver. A stationary non-contact proximity switch is mounted to be activated by the switch receiver when the door is closed and the pivotal plate is in a latched position. A ring receives a tongue projecting from the pivotal plate when the plate and handle are in the latched position. A pivotal hasp is movable around the ring into interference with the path of movement of the pivotal plate to block the plate from the fully latched position. A movable detent enables the plate and handle to be moved to the fully latched position only by moving the detent from exterior side of the plate.
