Abstract: What is presented is a unit cell comprising a cellular geometry that comprises cell walls and cell edges arranged into a combination of a cubic cell geometry and a tetrahedral cell geometry arranged to have a coincident central vertex. The cubic cell geometry comprises three orthogonal cell faces that intersect at its central vertex. The tetrahedral cell geometry comprises an arrangement of eight tetrahedral cells that share its central vertex such that each tetrahedral cell shares three coincident edges with three other tetrahedral cells in a cubically symmetric arrangement. The tetrahedral cell geometry is combined with the cubic cell geometry such that all vertices of the tetrahedral cell geometry are coincident with the vertices of the cubic cell geometry.

Abstract: Computer-implemented systems and methods for processing a financial transaction include receiving, from a device, a financial transaction comprising an account number associated with a financial account; based on a determination that the account number is suspended, determining whether authorization data associated with the financial account exists to authorize financial transactions associated with the account number after the account number is suspended; based on a determination that the authorization data exists, determining a first temporary identifier; receiving a second temporary identifier from the device; and based on a determination that the first temporary identifier is the same as the second temporary identifier, approving the financial transaction.

Abstract: Methods and systems for online collaboration. A method embodiment facilitates collaborative editing of a cloud-based shared document using a browser-enabled platform native application. A user launches a platform native application and establishes a non-browser connection between the platform native application and a remote cloud-based shared file facility. The non-browser connection operates independently from any browser connections even though the platform native application includes a document editor web app within the embedded browser. A first user retrieves a first user copy of the cloud-based shared document, modifies the document, and shares the modified document so as to be accessible by other collaborating users.

Abstract: What is presented is a unit cell that has a cellular geometry that comprises cell walls and cell edges arranged into a combination of a cubic cell geometry and a tetrahedral cell geometry and assembled structures that comprise a plurality of unit cells. The voids of the unit cell created by the combination of geometries comprise regular tetrahedrons, irregular tetrahedrons, and octahedrons. In some embodiments, the thickness of selected cell walls can vary and in some embodiments have zero thickness. In some embodiments selected cell walls and selected cell edges have a varied thickness. In other embodiments selected cell walls are non-planar. In some embodiments selected cell walls may have one or more holes. Selected cell edges of some embodiments of unit cell may have varying cross-sectional geometry that vary along a length of the cell edge. Some embodiments of the unit cell may comprise fillets to blunt stress concentrations.

Abstract: Techniques are disclosed for a web or mobile interface enabling users and collaborators to simultaneously comment, edit, or edit content in real time or near real time managed by a cloud-based collaboration platform. In one embodiment, the data to be accessed concurrently is presented or depicted at the multiple physical devices to the collaborators for viewing and accessing the data in real time or near real time. Each of the collaborators is able to view, re-edit, or re-modify in a concurrent fashion, at the collaborator's physical device, edits or modifications made to the data in real time or near real time as a result of any of the other collaborators accessing the data at their respective physical devices. In some instances, additional collaborators are specifiable for the data created for concurrent real time access in addition to those originally associated with the folder.

Abstract: Embodiments in the present disclosure include systems and methods related to a high-availability architecture for a cloud-based concurrent-access collaboration platform. The disclosed technology relates to an active data center which includes multiple document server instances that handle user requests for concurrently accessing documents. Multiple document server instances are implemented on a single physical server. This architecture uses an instance assignment manager to assign documents to the document server instances, a primary repository to store backup snapshots of the documents, and a datastore to store all changes made to the documents. The disclosed technology also involves a backup data center that can be swapped with the active data center automatically.

Abstract: Methods, structures, devices and systems are disclosed for implementing optical seismometers that detect seismic information based on optical interferometry. In one aspect, a device includes a first retroreflector attached to a mass of a seismometer, a second retroreflector attached to a member of a frame of the seismometer, the frame structured to suspend the mass, and optical components attached to the member of the frame and configured with the first and second retroreflectors to form an interferometer, in which a change in position of the mass is identified by detecting by a change in an optical path of a light beam generated by a light energy source transmitted to the interferometer.

Abstract: A method to share challenges between users of a social game system is described. The method may include accessing relationship data reflecting a relationship between a first user and a second user, and accessing challenge data in a challenge database. Based on (1) the challenge data and (2) the relationship between the first user and the second user reflected by the relationship data, the challenge data is selectively communicated as part of a challenge about the first user to the second user, with the challenge forming part of a challenge game.

Abstract: A search history application retrieves and displays a user's remotely stored search history. The search history is sent to the application in the form of a content feed. An email checking application receives a list of new emails as a content feed and displays the list of new emails. New emails for multiple accounts may be displayed concurrently in distinct instances of the email checking application. A blog posting application allows a user to select any of a plurality of blogs under the user's account and post to that blog.
