摘要： This invention comprises an architecture for voltage mode control of a voice coil motor in a hard disk drive. In contrast to conventional current mode control, coil current is not sensed or measured, which simplifies the feedback design with less hardware required in the implementation. Common design methodologies for the square root velocity profile, linear velocity profile and regulator/estimator control system designs can be migrated from the current mode architecture to the voltage mode architecture.

摘要： According to one embodiment of the invention, a method of moving a device from a first position to a second position by an actuation system includes moving the device in response to providing a control signal having a first amplitude for a first time period. The method also includes, immediately after the first time period, moving the device in response to providing a control signal having a second amplitude for a second time period, the device having a nonzero velocity after the second time period. The nonzero velocity has a magnitude that allows the device to coast to, and stop at, the second position after the second time period without receiving a control signal.

摘要： An actuator architecture allows precision control of a micro-actuator read/write head 16a, 16b by measuring the position directly with the read/write heads rather than relying on a position sensor. The position of the micro-actuator head 16a, 16b with respect to the conventional actuator assembly 12 is determined by comparing the position of the micro-actuator head 16a with the position of a second head 16b affixed to the conventional actuator 12 using disk servo patterns.

摘要： A pivoted platform has two flexible arms having rigid end zones which are attached by means of spacers to piezoelectric elements. The piezoelectric elements are made to deflect in opposite directions upon the application of the electrical signal to cause the platform to pivot. Applying voltages of the opposite polarity causes the platform to pivot in the opposite direction. A mirror may be attached to the platform to produce a scanning mirror for the vertical deflection of a television image.

摘要： A movable mirror device driven by a reluctance force motor is provided. A sheet of material has a mirror portion, a hinge portion, and a frame portion formed therein. The mirror portion is coupled to the frame portion via the hinge portion. The reluctance force motor is formed from a magnetic flux channeling circuit. A wire coiled about a portion of the magnetic circuit is used to induce a magnetic field through the magnetic circuit. Air gaps in the magnetic circuit provide attractive forces between portions of the magnetic circuit when a magnetic field is present in the magnetic circuit. The air gaps and the magnetic circuit are configured so that the magnetic attractive forces at the air gaps exert torque on the mirror portion about the hinge portion. When the hinge portion is twisted, it acts as a torsional spring biasing the mirror portion toward a neutral relaxed position.

摘要： Apparatus and methods for removing jitter and stabilizing the feed back system of a torsional hinged device with minimal changes to the system. The stabilization is accomplished by spatially isolating the pivoting mirror structure from all drive, support and packaging structures to reduce air drag. The mirror structures may be further stabilized by tailoring the drive mechanism and the position of the mechanism to produce substantially pure rotational drive torque on the mirror.

摘要： A system and method for providing resonant movement about a first axis. A functional surface supported by a first pair of torsional hinges is driven into resonant oscillations about the first axis by inertially coupling energy through the first pair of torsional hinges. The resonant movement may be moved orthogonally on the target area by a gimbals portion of the functional surface pivoting about a second axis according to one embodiment. The resonant oscillation of the functional surface is monitored to detect changes in frequency due to mass changes of the functional surface.

摘要： A piece-part microactuator (220), or micromotor, manufacturing approach is presented. In this approach, two of the NiFe parts (221,223) and dielectric and copper (225) piece-parts are manufactured separately. This allows the NiFe parts (221,223) to be designed in a manner to maximize the thickness of the metal, which in turn increases the magnetic properties of the motor. The dielectric and copper coils piece-part (225) may be based upon a thin film interconnect (222) or some derivative of a standard flex circuit printed wiring board. These piece-parts (221,223,225) may be tested individually, defective parts discarded, and only functional units assembled. This not only produces a mechanically balanced construction, but has lower cost due to non-sequential manufacturing steps. The dielectric and copper coils piece-part (225) also provides the path for electrical connections to the movable platform (234) and a relatively easy method for electrical connection off the microactuator and onto the hard disk drive system.

摘要： Apparatus and methods for removing jitter and stabilizing the feed back system of a torsional hinged device with minimal changes to the system. The stabilization is accomplished by introducing a selected amount of lateral motion (in addition to the rotational motion) by creating asymmetry in the oscillating device or the drive torque applied to the device.
