In a method for determining the elongation of segments of a chain of a chain drive during operation, a plurality of measured values is determined at different positions of the chain. A plurality of length values is determined from the plurality of measured values and a position of the segments of the chain is determined. The length values are assigned to the segments of the chain, with the length of the segments of the chain being smaller than the length of the chain.

A tree harvesting head for a tree harvesting machine, wherein the tree harvesting head comprises at least one cutting device, at least two feed wheels and a radar device. The radar device comprises at least one radar transmitter antenna arranged to transmit a signal to a tree trunk to be measured, at least two radar receiver antennas arranged to receive a radar signal reflected in at least a first and a second location in response to the transmitted radar signal, wherein the first and second locations are different locations.

Inspection devices and methods for inspecting an adhesive pattern on a substrate are disclosed. The inspection device includes at least one sensor having a heat sensor head for detecting a pattern of the adhesive bead, and a controller. Reference data representing a desired adhesive pattern is initially provided to a controller. A predetermined tolerance range for the desired adhesive pattern is also provided to the controller. An adhesive bead is discharged onto a substrate from a nozzle. A pattern of the discharged adhesive bead is then detected by the sensor when the substrate moves. Signals representing the detected pattern are received from the sensor at the controller. Finally, the signals representing the detected adhesive pattern are compared to the tolerance range of the desired adhesive pattern.
