Abstract: Systems and methods for wide format ink printing are described. In one embodiment, a tension module for wide format inkjet printers is described which includes a throughput roller comprising a material having a length to diameter ratio of at least 10:1 and a friction coefficient value less than 1. The tension module further includes a plurality of pinch rollers adjacent to and supporting the throughput roller, and a motor operable to rotate the throughput roller. The plurality of pinch rollers and the rotation of the throughput roller in combination are operable to draw the print medium between the plurality of pinch rollers and the throughput roller.

Abstract: A data center includes a building having a pitched roof. The building includes a ventilation gallery extending a length of the building. The ventilation gallery is formed at a peak of the pitched roof and includes vertical louvered walls. The data center includes an equipment gallery structurally supporting the ventilation gallery and including exterior vertical walls forming the length and a width of the building. A series of electrical equipment is mounted in equipment racks in the equipment gallery arranged in two rows forming a common aisle between the two rows. The electrical equipment includes coaling inlets oriented toward the exterior vertical walls and exhaust outlets oriented toward the common aisle. Aisle separators extend vertically from the equipment racks to the ventilation gallery.

Abstract: In a forwarding device connected to a network including a plurality of communication nodes connected to each other, in which a plurality of communication routes, each for forwarding a signal through at least one of the communication nodes can be present between arbitrary ones of the communication nodes, a forwarding method according to the present invention determines that the received packet is a BPDU or a local BPDU, and discards the BPDU if the received packet is the BPDU and fetches an original BPDU from the local BPDU if it is the local BPDU. In the case where the BPDU is to be transmitted, the BPDU is created and wrapped in a format of the local BPDU. Then, the wrapped BPDU is broadcasted. In this manner, the local BPDU can be exchanged without affecting the other bridges having a normal spanning tree function.

Abstract: A system comprises a processor and non-volatile storage coupled to the processor. The non-volatile storage comprises firmware that is executable by the processor. The processor determines whether the firmware is available to be executed. If the firmware is not available to be executed, the processor determines a location across a network and retrieves a second firmware image from that location.
