Latest Patents

One of Ritchie's latest patents is the Optical Inclination Sensor. This device features at least one reflective surface and two separate optical fibers. As the reflective surface tilts from a predetermined reference position, the gap lengths between the fiber ends and the reflective surface change. These differences in gap lengths are utilized to calculate the angle of inclination. The sensor can also include a mass that moves with respect to a housing, allowing for precise measurements of inclination.

Another significant patent is the Filter-Switched Drive Operating Mode Control. This invention involves a controller for a pulse width modulated electrical drive. It is designed to detect failures in the filter or its components through integrated sensors. Upon detecting a failure, the controller can either shut down the drive or switch to an output mode that does not require filtering. This innovation helps prevent damage to electrical systems and downhole equipment.
