  • Patent number: 9120232
    Abstract: An end effector configured to pick up an item may comprise a vacuum port through which a vacuum is selectively drawn, a first vacuum pathway in communication with the vacuum port and defining a first open bore, a pin pathway and a pin disposed within the pin pathway and configured for constrained movement therein. The pin may be further configured to protrude from the end effector body, to contact the item and to move within the pin pathway until the item contacts the first open bore and is retained by the end effector by the force of the vacuum. Turning off the vacuum may cause residual vacuum in the first vacuum pathway to retain the item for a period of time and/or until the pin drops under its own weight within the pin pathway to contact and separate the item from the end effector.

  • Publication number: 20150052393
    Abstract: Back-up of data to flash memory. Data to back up is written into stripes, which are sets of pages across flash memory backup devices having the same block and page address. First metadata is embedded in each stripe indicating any blocks of the flash memory known to be bad. In response to encountering a new error in a block of flash memory during writing data to back up to a stripe, re-writing the stripe starting at the next available stripe excluding pages on the block of flash memory having the new error, writing subsequent stripes excluding pages on the block of flash memory having the new error, and embedding second metadata in the re-written and subsequent stripes indicating the location of the block having the new error. Responsive to finding no bad blocks indicated in the first metadata, initiating a write to two or more stripes simultaneously.

  • Patent number: 8330484
    Abstract: An integrated circuit and method of testing the integrity of the electrical connection of the integrated circuit to external equipment are provided. The integrated circuit comprises an output port including output contacts for coupling the integrated circuit to external equipment, via external connectors. The output port receives internal operational signals and routes the operational signals to the output contacts for connection of the operational signals to external equipment. A connection test signal store is dynamically loadable with test signals. Signals sent to the output port can be switched between the test signals and operational signals. External equipment monitors the integrity of an electrical connection between the output contacts and the external connectors by detecting expected transitions in the test signals.

  • Patent number: 7996801
    Abstract: Methods and systems for on-the-fly chip verification method for tracking non-contiguous events. A method includes comparing a first search marker associated with a first check vector to a search key associated with an output vector of a design under test (DUT). The method also includes performing either: verifying a validity of the output vector when the first search marker equals the search key, or comparing a second search marker associated with a second check vector to the search key when the first search marker does not equal the search key.
