An interactive software application on a mobile computing device is used to configure an electronic torque wrench via a wireless connection. The software application obtains torque specifications for a vehicle from a remote database. When the torque specification require that work pieces be torqued in an ordered sequence, the software application guides the technician through the sequence, but accommodates changes when the technician departs from the sequence.

According to some embodiments, system and methods are provided, comprising an installed product including a drive shaft; a magnetostrictive sensor having a sensor probe comprising: a substrate; a drive coil operative to receive a drive current and to emit a magnetic field through the drive shaft, wherein the drive coil is mounted on the substrate; one or more sense coils operative to receive the magnetic field and to transmit a signal based on the received magnetic field, wherein the one or more sense coils are mounted on the substrate; and wherein the magnetic field is emitted from the drive coil in a transverse direction to a radius of the drive shaft. Numerous other aspects are provided.

A highway grade crossing gate mechanism having a smart cam system capable of measuring a parameter of the gate mechanism in real time is provided. The gate mechanism includes a DC motor, a cam system, and a controller. The DC motor is coupled to a main shaft for driving a gate arm between a vertical position and a vertical position. The cam system includes manually adjustable cams coupled to the main shaft that move contacts to open or close at some preset angular rotation in order to set operational features of a crossing gate. An internal sensing device is disposed internal to the cam system measuring a parameter of the gate mechanism in real time. A controller controls the motor and receives and stores the parameter. The parameter may be transmitted to an external network giving accurate feedback of the state of the gate mechanism in real time.

A concept for torque measurement on a shaft is described. To that end, millimeter waves are transmitted in the direction of a first encoder structure, which is coupled to a first shaft section of the shaft for conjoint rotation and is arranged around the shaft, and in the direction of a second encoder structure, which is coupled to a second shaft section of the shaft for conjoint rotation and is arranged around the shaft. The first encoder structure and the second encoder structure are rotatable relative to one another in the case of a torque to be transmitted via the shaft. At least one reception signal is generated on the basis of millimeter waves reflected or transmitted by the first and second encoder structures. A torque transmitted using the shaft is determined on the basis of the at least one reception signal.
