Sep 28, 2007

Appl. No.:

11/864036

Inventors:

Kenneth Choi - Montara CA, US
Anna Falche - Oakland CA, US
Richard Naughton - San Diego CA, US

Assignee:

KAR LLC - San Francisco CA

International Classification:

B63B 17/00
B63B 35/00
E02B 3/20
G06F 17/30

US Classification:

114 561, 405218, 707 10, 7071041, 707E17001, 114343

Abstract:

The Self-Sustaining Data Center makes use of a site that is inherently immune to catastrophic events and incorporates features to facilitate the substantially continuous availability of data stored therein. The architecture of the Self-Sustaining Data Center makes use of multiple data communication links to sites that are remote from the data center to enable the uninterrupted communication access of customers' computer systems to the mass storage systems operational at the Self-Sustaining Data Center. The Self-Sustaining Data Center also includes facilities that include at least one of: power generation, housing and food for data center staff, and voice communications facilities, thereby to enable the Self-Sustaining Data Center to continue its operation for an extended period of time in the absence of municipal utility services and the possible inability of the data center staff to access outside sources of food and water.

Inventors:

Kenneth Choi - Santa Clara CA, US

International Classification:

H05K 7/20

Abstract:

In an open-loop heat removal system for a building such as a data center or a home, cool air is supplied to the building by a chilling unit and hot air is expelled from the building without recycling, recirculating, or re-cooling the hot air. For fire suppression, the system receives temperature reading(s) from temperature sensor(s) and determines whether any temperature reading reaches or exceeds a temperature that indicates presence of a fire. If so, a louver positioned over an inlet module is automatically or programmatically closed, shutting off air supply to the building. The system determines whether the building is under a negative pressure internally. If not, an exhaust fan at the outlet of the building is turned on to create a negative pressure internally. The system determines whether an oxygen level of the building indicates that the fire has been contained. If not, a sprinkler system is activated.

International Classification:

G06Q 10/06
G06Q 10/10

Abstract:

Disclosed are systems, methods, and non-transitory computer-readable storage media for managing project tasks using content items. A user can create tasks within a content item. The tasks can be assigned to users and/or be assigned due dates. The content item can be shared with other users such that updates to the content item (e.g., updates to the tasks) can cause sending notifications to users associated with the content item. When a task in the content item is updated, all members of the project can be notified of the updated status of the task. A task list for a project can be created that aggregates tasks from multiple content items associated with the project. Tasks can be organized in the task list according to the content item the task was created in. Updates to tasks in the task list can cause corresponding updates to the tasks in the content items.

Abstract:

Disclosed are systems, methods, and non-transitory computer-readable storage media for managing projects using references between the project and project items. Project items can be, for example, synchronized content items, collaborative content items, other projects, folders, tasks, user accounts, etc. The content management system can create a project identifier for managing data and/or people associated with a project. In various implementations, the content management system can store references between the project and project items in one or more folders associated with the project, in a database, in content item metadata, etc. In some implementations, the storage location of a content item does not affect whether it is associated with the project. When a project is selected by a user, the content management system can generate project view that presents various project items associated with the project in a convenient and easy to access graphical user interface.

Inventors:

Dale LeFebvre - Thomas VI, US
Kenneth Choi - San Francisco CA, US

International Classification:

H05K 7/20

Abstract:

As air inside a building (e.g., a data center or any building that generates heat) becomes heated, it rises and is received or captured by a heat containment and then expelled from the building. The hot air is not recycle, recirculated, or re-cooled. Hot air being expelled from the building creates a pressure differential in which the pressure at the hot side of the building (where the heat containment is located) is lower than the cool side of the building. To this end, a chilling unit is installed at an opening of a building to supply cooled air at a constant rate. The chilling unit does not have an internal controller. Rather, an air conditioning (AC) unit of the building acts as an external controller. The AC unit is be set to maintain a target temperature and only runs when the temperature inside the building is above the target temperature.
