Abstract: An inspection sensor module for an in-line pipe inspection tool has a support for mounting the module on the tool, a finger pivotally attached at one end to the support and pivotally attached at the other end to a sensor block carrying one or more inspection sensors. A first leaf spring extends from the support to the finger to bias the finger outwardly, and a second leaf spring extends from the support to the carrier to bias the sensor block. Biasing sensors are mounted on the leading and trailing edges of the first leaf spring to detect movement of the first leaf spring corresponding to movement of the inspection sensors towards or away from the support.

The control generates a control output responsive to the processing, and the control output is indicative of the detection of the tool and the geographical location of the detection and communication device. A display device receives an input indicative of the control output and displays the information indicative of the detection of the tool and the geographical location of the detection and communication device to a user of the display device.

Abstract: Testing of engine particulate matter production during a transient is made more accurate by selecting an appropriate sized opening for a test probe of the sampling system located in the exhaust line upstream from a particulate trap. By examining the pressure signature at the test probe location and utilizing that information in conjunction with a desired volumetric flow rate into the sampling system, a flow opening size for the test probe can be selected that reduces potential oversampling which may be otherwise induced due to the back pressure increases in the exhaust line caused by the presence of the particulate trap. The flow opening into the test probe of the sampling system behaves relative unrestricted when pressure differentials at the test probe location are relatively low, such as during steady state operating conditions, but restricts flow into the sampling system when pressure differentials are relatively high, such as at a pressure during a transient event.

Abstract: There is described a method for monitoring a drive device for a defective sensor signal from a first sensor of the drive device and to a monitoring device which is suitable for this purpose. Although sensors operate reliably, sensor errors which may give rise to significant damage if they are not detected may arise. Monitoring the sensor makes it possible to increase the reliability of the drive device. The sensor signal from the first sensor is compared with a sensor signal from a second sensor in such a manner that the first sensor is monitored. In this case, the monitoring device is intended, in particular, for a sensor having a sensor disc.
