  • Patent number: 9022020
    Abstract: Described herein are solar energy collector systems, components for solar energy collector systems, and methods for installing solar energy collector systems. The components for solar energy collector systems include but are not limited to solar radiation absorbers, receivers, drives, drive systems, reflectors, and various support structures. The solar energy collection systems, solar radiation absorbers, receivers, drives, drive systems, reflectors, support structures, and/or methods may be used, for example, in LFR solar arrays. Drives and drive systems are described herein that may provide improved rotational positioning, movement, and/or rotational positional sensing. For example, drives and drive systems are provided which allow operation through a variable frequency drive. The components and methods described herein may be used together in any combination in a solar collector system, or they may be used separately in different solar collector systems.

  • Patent number: 8229908
    Abstract: One embodiment of the present invention provides a system that facilitates dividing financial data to facilitate simultaneous modifications by multiple users. During operation, the system receives division-criteria, which facilitates dividing financial-data into a first subset and a second subset. Next, the system creates a copy of the financial-data which includes the division-criteria. The system then allows a first user to modify the first subset of the financial-data. The system also sends the copy of the financial-data to a second user, thereby enabling the second user to modify the second subset of the financial-data in the copy of the financial-data to create a change file. Subsequently, the system receives the change file from the second user, wherein the change file comprises modifications to the financial-data. Finally, the system merges the change file into the financial-data.

  • Publication number: 20080270310
    Abstract: Embodiments of a system that provides access to at least a portion of a software product are described. During operation, this system receives purchase information from a first location, where the purchase information includes information about purchased software features to which a user purchased access and where the purchased software features are provided by a first subset of modules in the software product. Next, the system receives an access request from a second location from which the software product can be accessed, where the access request includes an identifier provided to the user when the user purchased access to the purchased software features. Next, the system provides configuration instructions to the second location, where the configuration instructions dynamically enable the first subset of the modules.
