  • Publication number: 20210260843
    Abstract: A bead forming system for forming a tire bead may include the following: a housing, a first bead former configured to facilitate the formation of the tire bead, and a base secured to the first bead former, where the first bead former includes a bead-receiving surface that is rotatable relative to the base. The base may be adjustable such that the first bead former is movable from a first position to a second position. The first position may be on a first side of the housing, and the second position may be on a second side of the housing. A second bead former may be located in the second position when the first bead former is located in the first position, where the second bead former is located in the first position when the first bead former is located in the second position.

  • Patent number: 7862622
    Abstract: A prosthetic foot having an adjustable height heel includes a frame portion with an ankle link pivotally supported on the frame portion at a first pivot axis. A detent rod is pivotally connected to the ankle at a second pivot axis, and a detent member is pivotally affixed to the frame portion at a third pivot axis. The detent member is selectively operable to receive and releasably retain a length of the detent rod therein so that the length of the detent rod extending between the second and third pivot axes may be selectably adjusted. When the length of the rod is so adjusted, the angular relationship of the frame portion and the ankle link is changed thereby changing the heel height of the foot. The detent mechanism may be activated by various means including fluidic means, mechanical means, electromechanical means, and the like.

  • Publication number: 20100262979
    Abstract: A method for communicating commands between a host and a flash memory data storage device includes populating a circular command queue of a driver on the host with commands for retrieval by the data storage device, transferring commands from the circular command queue to the data storage device via a device initiated direct memory access operation, populating, via a direct memory access operation initiated by the data storage device, a circular response queue of the host with responses by the data storage device for retrieval by the host device, where each response acknowledges the reception of a command from the host by the data storage device, and consuming responses from the circular response queue at the host.

  • Patent number: 7698509
    Abstract: A multiprocessing node has a plurality of point-to-point connected microprocessors. Each of the microprocessors is also point-to-point connected to a filter. In response to a local cache miss, a microprocessor issues a broadcast for the requested data to the filter. The filter, using memory that stores a copy of the tags of data stored in the local cache memories of each of the microprocessors, relays the broadcast to those/microprocessors having copies of the requested data. If the snoop filter memory indicates that none of the microprocessors have a copy of the requested data, the snoop filter may either (i) cancel the broadcast and issue a message back to the requesting microprocessor, or (ii) relay the broadcast to a connected multiprocessing node.
