Abstract: A method (480, 580) of depositing layers of a thin-film transistor on a substrate using a sputter deposition source comprising at least one first pair of electrodes and at least one second pair of electrodes, the method comprising moving (482, 582) the substrate to a first vacuum chamber; depositing (484, 584) a first layer of the layers on the substrate by supplying the at least one first pair of electrodes with bipolar pulsed DC voltage, wherein a first material of the first layer comprises a first metal oxide; moving (486, 586) the substrate from the first vacuum chamber to a second vacuum chamber without a vacuum break; and depositing (488, 588) a second layer of the layers on the first layer by supplying the at least one second pair of electrodes with bipolar pulsed DC voltage, wherein a second material of the second layer comprises a second metal oxide, the second material being different from the first material.

Abstract: Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium for firewall policies with improved efficiency. A policy can be defined that specifies a set of firewall rules, where the set of firewall rules provides a respective firewall rule for each layer of a plurality of layers within a hierarchical structure of a network, the network including a plurality of elements. Determining, for a first element within the network, a position within a first layer of the hierarchical structure. In response to receiving a data transmission request to or from the first element, applying the set of firewall rules in accordance with the first layer of the hierarchical structure, where applying the set of firewall rules comprises sequentially applying each respective firewall rule at each layer from an upper layer within the network to the first layer within the network.

Abstract: A content specification containing a data structure describing a digital volume to be incorporated into a digital library is received. A digital volume is a digital representation of human-readable content, such as a digitized book. Volume content of the digital volume is obtained based on references in the content specification to the locations of the volume content. The volume content is indexed based at least in part on information in the content specification, including volume metadata such as the title or author of the volume. The content specification includes markup language elements, each element specifying information about the digital volume. A plurality of tags are associated with the markup language elements. A structural tag specifies structural information associated with the digital volume, including the location of a portion of volume content of the digital volume. A metadata tag specifies metadata describing or identifying the digital volume.
