  • Publication number: 20250163980
    Abstract: A piston for the actuation of a brake pad, the piston comprising a body having a base end, a pad end and a side wall formed therebetween, an axis X extending from the base end to the pad end, the pad end having a cap contact surface at a non-zero angle relative to the axis of the body; a cap movably secured to the body at the pad end, the cap being arranged over the cap contact surface and having a pad contact face and an opposite body contact face; and a resilient member arranged between the body and the cap; wherein, on application of a braking force, the cap is arranged in an initial position where the cap contact surface of the body is spaced apart from the body contact face of the cap, whereby the cap is moveable transversely relative to the axis of the body into an intermediate position; and wherein the cap is moveable axially relative to the body from the intermediate position into a final position where the cap contact surface contacts the body contact face such that movement of the cap transversely r

  • Patent number: 8301671
    Abstract: A method, apparatus and computer program product for providing removal of replicated objects based on garbage collection is presented. Data objects are replicated from a primary source to a backup device. A notification is received from a garbage collection process for at least one data object replicated from the primary source to the backup device, the notification indicating that the data object should be deleted. The data object having the notification is deleted from the backup destination.

  • Publication number: 20050128629
    Abstract: Methods in accordance with the present invention can include determining a position of a head along a stroke by locating one or more marker-zones printed to a reference surface of a disk. The one or more marker-zones can be printed to a portion of the reference surface as one or more pulses from a template pattern that can further comprise a plurality of chevrons. In one embodiment, each pulse can trace the motion of the stroke along at least a portion of the radius of the reference surface. A pulse can identify a marker-zone edge when the pulse disappears at some radius from the center of the disk. By moving the head along the stroke, the marker-zone edge can be detected and a gross position determined. A fractional position can be determined by measuring a phase of a chevron located at substantially the same radial location as the edge.

  • Publication number: 20050128620
    Abstract: Template patterns in accordance with the present invention can include one or more maker-zones printed to a reference surface of a disk for determining gross-position along a stroke of a read head connected with a rotary actuator. The one or more marker-zones can be printed or otherwise written to a portion of the reference surfaces as one or more pulses. In one embodiment, each pulse can trace the motion of the stroke along at least a portion of the radius of the reference surface. A pulse can identify a marker-zone edge when a di-bit (a transition pair representing a pulse) disappears at some radius from center of the disk. At a radius closer to the center of the disk, the di-bit can abruptly reappear so that the pulse is continued. The interruption in the radial continuity of the magnetized pulse defines the marker-zone and can be any length.

  • Patent number: 6078316
    Abstract: An optimized refresh strategy for increasing bandwidth of an LCD. The present invention results in an LCD suitable for dynamic display of information. In the present invention, a display memory is used to store display data generated by a CPU and to provide that data to an LCD. All data writes to the display memory by the CPU are tracked and rows or columns that contain modified data are tagged. These tags may be "set" by mapping the display memory write addresses to row or column numbers. The tags are examined and mapped back into the display memory addresses and only those rows or columns containing changed data are transferred to the data stream for display. As a result, only the information that is changed in the display memory is sent to the display and the dynamic bandwidth of the display is maximized. The refresh in the present invention can be either row-based or column-based.
