A sensing apparatus for detecting speed bumps or potholes on a road is disclosed. The sensing apparatus comprises a telemetric sensing system configured to collect a plurality of position vectors by telemetric sensing of a road surface, wherein each position vector extends from a common origin to a respective point on the road surface and wherein each position vector has a length and a direction. The sensing apparatus further comprises a processing circuitry configured to detect a road flatness exception by evaluating the lengths of the position vectors. Thus, an improved apparatus for detecting road irregularities such as speed bumps or potholes on a road is provided. The sensing apparatus remains functional in low light conditions, e.g., at night, and also in the presence of reverberation of the vehicle. In an implementation form, the telemetric sensing system may comprise one or more radar sensors and/or one or more lidar sensors for collecting the plurality of position vectors using radar and/or lidar measurements.

A probe assembly for measuring a synthetic turf infill profile having a probe, a turf surface contact assembly and a sensor. The probe is configured to extend down through the turf infill profile until a tip of the probe contacts a lower boundary of the turf infill profile. The surface contact assembly is vertically movable relative to the probe while the probe is being moved downwardly into the turf infill profile, wherein the surface contact assembly has a contact area with the turf surface that is large enough to retain the surface contact assembly resting atop an upper boundary of the turf infill profile when the lowermost tip of the at least one probe has contacted the lower boundary of the turf infill profile. The sensor reads the distance between the upper and lower boundaries of the turf infill profile at a sampled location in the turf surface.

A tool having an energy source and a surface roughness measurement device is provided. A baseline measurement of surface roughness of a sample is made. The sample is then exposed to energy from the energy source, causing the temperature of the sample to increase. A second measurement of surface roughness of the sample is made. The change in surface roughness of the sample is determined. Formation properties such as the total organic carbon in the sample is inferred based on the determined change in surface roughness of the sample. The tool may be disposed in a wellbore and may use packers to isolate a portion of the wellbore, or it may use a hydraulic seal on an extendible member to isolate a sample portion of the wellbore wall. The energy source may be a laser that produces radiation that selectively heats a particular component of the sample constituent material.

A flatness-measuring roll for detecting flatness defects of a metal strip extending and moving in a strip-travel direction has a roll body having a cylindrical outer surface and a central axis extending generally perpendicular to the strip-travel direction and about which the body is rotatable. A plurality of measuring bars axially spaced along the body, recessed in the body, and having outer faces flush with the body surface are each at least limitedly radially shiftable relative to the body. The bars are angularly elongated, each extend along a plane substantially perpendicular to the roll axis, and each have a constant width measured parallel to the roll axis over generally all of a respective total angular length. At least two respective force-measuring sensors are braced radially between each of the bars and the roll body.
