    摘要： Heart pacing systems include at least one electronic or biological pacemaker as a primary pacemaker, and at least one electronic or biological pacemaker as a backup pacemaker. When implanted, the primary pacemaker(s) produce primary pacing stimuli that modulate cardiac function. The backup pacemaker(s) provide backup pacing stimuli when the electronic pacemaker is unable to modulate cardiac function at the predetermined pacing rate. The heart pacing systems are implemented by implantation in regions where they can provide pacing stimuli to cardiac tissue.

    摘要： Head gimbal assembly (HGA) may include a piezo layer mechanically coupled with the slider or include a piezo element mechanically coupled by the flexure to the slider top near the read-write head. A bridge flex circuit is included, providing a piezo-control bundle to at least one piezo layer lead. A flex circuit assembly may further provide a piezo control bundle, shared with piezo control bundles for multiple read-write heads. HGA may include a micro-actuator to position read-write head near track on accessed, rotating disk surface. Flex circuit assembly may provide a source control bundle, shared with the micro-actuator control bundles for multiple read-write heads. When accessing, all micro-actuators perform same positioning action, insuring proper positioning of read-write head. This applies to both co-located and non co-located micro-actuators. Wire bundles may include one or two active signal wires. Voice coil actuators and hard disk drives, and their manufacture, are included.

    摘要： The invention operates two control paths. The micro-actuator control stimulates the micro-actuator. The voice coil motor control path includes the voice coil motor control generating a voice coil control signal, notch filtered to remove at least one significant excitation resonance for a notch filtered voice coil control signal. Amplifying the notch filtered voice coil control signal by a tuning gain stimulates the voice coil motor.A decoupling feedback filter uses the micro-actuator control signal to create a decoupling feedback signal used to decouple the two control paths. A track following command, with PES removed, directs the micro-actuator control. The voice coil motor control is directed by the track following command, with both PES and decoupling feedback signal removed.Preferably, the servo-controller digitally supports the elements of the invention. Implementing the method may preferably include the servo-controller program system residing in an accessibly coupled memory.The invention includes optimizing an implementation within the hard disk drive. The optimization may be part of the manufacturing process for the hard disk drive. The invention includes the hard disk drive as the product of that manufacturing process.

    摘要： A method and apparatus is disclosed to compare numbers for equality. The numbers represented in a redundant form, including numbers received from a bypass circuit are subtracted. More specifically, a complemented form is generated and supplied to an arithmetic circuit for at least one number represented in the redundant form. Input to the arithmetic circuit is adjusted to augment a result generated through the arithmetic circuit to generate a valid outcome represented in the redundant form as a result of a subtraction operation. Results of the subtraction operation are compared to zero in redundant form using a non-propagative circuit and without requiring carry propagation, thereby producing an equality comparison of the number in redundant form.
