Latest Patents

Bradley's most significant patent is an electronic velocity measurement device. This device combines a differentiated cyclically discontinuous displacement (position error) signal with integrated motor current signals. The result is an accurate continuous velocity signal that operates effectively across the entire range of displacements of a linear actuator. The differentiation of the displacement signal is achieved through low bandwidth differentiator circuitry, which is corrected for periodic reversal of the displacement signal. This correction is accomplished using a unique fill-in signal derived from integrated motor current. In a specific embodiment, the fill-in signal is generated by a second differentiator that utilizes a second displacement signal in space quadrature with the primary displacement signal. Bradley holds 1 patent for this innovative device.
