  • Patent number: 11972977
    Abstract: A method of forming interconnects is provided. The method includes forming a plurality of mandrels on an interlayer dielectric (ILD) layer. The method further includes forming sidewall spacers on opposite sides of the each mandrel, wherein a portion of the ILD layer is exposed between adjacent sidewall spacers on adjacent mandrels, and removing the exposed portions of the ILD layer to form a first set of trenches between adjacent sidewall spacers. The method further includes forming a first set of interconnects in the first set of trenches, and removing the mandrels to expose portions of the ILD layer between the sidewall spacers. The method further includes removing the exposed portions of the ILD layer to form a second set of trenches between the sidewall spacers, and forming a second set of interconnects in the second set of trenches.

  • Publication number: 20240028995
    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.

  • Publication number: 20230255001
    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.

  • Publication number: 20220408605
    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.

  • Patent number: 10970679
    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.

  • Patent number: 10667436
    Abstract: New heat removal systems and methods allow a combination of active and passive thermal processes for removing heat from and cooling air in environments. Systems and methods include a heat removal system including an adjustable thermal feed cold air intake system, a distribution system for cold and warm air including one or more hot aisles and one or more cold aisles, and a convection system to draw cool air through the building using a naturally-occurring convection processes to expel hot air. Misters, cooling elements, and/or freezer boxes may further cool the intake of air. A controller is programmed to efficiently manage and control the climate (e.g., temperature, humidity, air flow, pressure, air quality, etc.) within a building to minimize the use for energy for air distribution and cooling.
