Abstract: A two-level hierarchical communication architecture for segmented material conveyors having separate motor zones for sensing and control is presented herein. The architecture utilizes peer-to-peer serial communications among a plurality of motor zones to coordinate the article handling actions of those zones. Specific communications connectivity and message content schemes are used to better provide ZPA functionality that is performed in prior art conveyors by discrete contact-logic single bit “look-ahead” wiring. Additional features of the present invention include variations on placements of one or more barcode, tag reader or article presence sensors; a variable speed ZPA scheme; and a token-passing scheme for relaying pre-arranged article routing decisions among zone controllers.

Abstract: An actuator assembly includes a first actuator arm and a second actuator arm, each having a first end and a second end, a support member, and a bearing assembly coupled to the arms and the support member, and supporting the arms and support member for rotation about an axis. The bearing assembly has a first portion abutting the first actuator arm and second portion abutting the second actuator arm, with the first and second arms being secured against movement away from each other by the bearing cartridge. Also provided is a retainer for preventing rotation of the first actuator arm about said axis relative to the second arm. The retainer may comprise first and second fasteners provided at opposite sides of the axis. In an alternative embodiment, the retainer comprises a leaf spring having a notch provided therein on the first and second actuator arms, and a fastener member provided on the support member.

Abstract: A member securing electrical conductors coupled to a read/write head in a storage device over termination pads of an electrical flex circuit. Generally, the storage device includes an actuator having at least one actuator arm securing the read/write head, and the apparatus is coupled to the actuator arm. The apparatus may comprise a member having a first end and a second end, the first end being coupled to the arm and the second end positioning the conductors over conductive pads of the flex circuit, with the second end including a window securing the conductors in fixed positions over the conductive pads of the flex circuit. In another arrangement, the second end comprises a solderless coupling assembly electrically connected to the conductors, wherein the conductive pads of the flex circuit are arranged to electrically couple to the solderless coupling assembly.

Abstract: The method for assembling the drive includes: providing an assembly member; stacking a first actuator arm and a second actuator arm in an orientation where the axes of the arms are non-parallel; inserting a comb assembly between the first and second arms; rotating the arms about the assembly member to a position where the radials are in parallel; and securing the arms against rotation relative to each other. In another aspect, wherein each arm includes a read/write head having wires coupled thereto, the method further including the step of attaching a wire carrier to the arm prior to the stacking step.
