Latest Patents
Dinsmore's latest patents include innovative methods for improving the operation of disc drive actuators. One of his patents involves applying a ramped voltage source across an actuator coil to retract a disc drive actuator. This system utilizes a voltage generator circuit that produces discrete DC voltage levels, a timing circuit for generating timing pulses, and a selection circuit that outputs a voltage profile of increasing voltage steps. This voltage profile is crucial during the parking operation of the actuator, ensuring that the driver circuit acts as a voltage source for the voice coil motor. The design minimizes acoustic noise during operation by controlling the terminal velocity of the actuator.
Another significant patent by Dinsmore addresses adaptive compensation for hard disc drive spindle motor manufacturing. This invention provides an apparatus and method for adaptively compensating for variations in the rotational speed of a back EMF commutated spindle motor. The hard disc drive enters a learn mode to characterize systematic variations in operational speed, which is then used to output modified speed control and commutation timing signals during the compensation mode.
