His expertise and creativity have led to the development of a unique patent that enhances the functionality of SMA actuation assemblies.
Latest Patents
John Grayley holds a patent for "Centring control of an SMA actuation assembly." This invention involves an SMA actuation assembly comprising SMA actuator wires connected in tension between a support structure and a movable element. The assembly is controlled to drive the movement of the movable element concerning the support structure by supplying drive signals to the SMA actuator wire. Target signals representing desired positions of the movable element are set, varying within a predetermined spatial envelope. Measures of resistance of the SMA actuator wires are derived, and the power of the drive signals is controlled under closed-loop control based on the target signals and feedback signals obtained from the measures of resistance. Electrical characteristics of the SMA actuator wires are monitored to detect when a motion limit of the movement is reached. In response, the spatial envelope is adjusted to restrict the movement within the detected motion limit.
