Molecular compositions, materials, and methods for efficient multiple exciton generation

Embodiments of the present invention provides compounds, compositions, and methods for their preparation that provide efficient intramolecular fission, such that local order and strong nearest neighbor coupling is no longer a design constraint. Inventive materials include organic oligomers and polymers designed to exhibit strong intrachain donor-acceptor interactions and provide intramolecular singlet fission, whereby triplet populations can be generated in very high yields of, e.g., 170% or more. The inventive disclosure is directed to polymers of the general formula: [SA-SD]n with a strong electron acceptor (SA), a strong electron donor (SD), and n a positive integer equal to or greater than two; methods for their preparation and monomers used therein, blends, mixtures and formulations containing them; the use of the polymers, blends, mixtures and formulations as semiconductors in organic electronic (OE) devices, especially in organic photovoltaic (OPV) devices, and to OE and OPV devices comprising these polymers, blends, mixtures or formulations.

Credit based flow control mechanism for use in multiple link width interconnect systems

Flow control credit management is provided when converting traffic from a first parallel link width on a first link to a second parallel link width on a second link A current value is calculated for a variable flow control credit exchange rate (R) associated with the first and second links. A first flow control credit indicator is received on the second link, and a credit amount calculated based on the first flow control credit indicator and R. A second flow control credit indicator for the credit amount is then transmitted on the first link.

Determining the ballistic threshold velocity for a composite structure using multiple failure models

A composite structure, such as a laminated composite panel, for example, comprises one or more layers or “plies” embedded in a matrix material or otherwise fixed together in an arrangement, commonly referred to as a “stack up.” Each material in the structure has a corresponding material failure model (MFM) defining the physical characteristics of that material. A ballistic threshold velocity computing device obtains the MFMs for each material in the composite structure, generates a predicted ballistic velocity threshold velocity for each MFM, and then generates a parametric model to compute a composite ballistic velocity threshold velocity for the composite structure.

Multiple pulse charge transfer for capacitive deionization of a fluid

The present disclosure relates to a capacitive deionization system which makes use of a controller, a first capacitor acting as a first electrode, a second capacitor acting as a second electrode, and a first inductor for storing energy received from the first capacitor, and transferring the stored energy to the second capacitor. A first plurality of electronic switches are controlled by the controller to control communication between the first inductor and the first capacitor, and between the first inductor and the second capacitor. An additional energy transfer subsystem is included which has a second inductor for receiving energy from the first capacitor while the first inductor is transferring stored energy to the second capacitor.

Software Coordinates Multiple Smart Devices and User Preferences, Redefining "Smart" Homes

NREL developed foresee™ to achieve users' preferences while simplifying the coordination of when and how a home's connected appliances and electronics use energy. This reduces complexity and improves the consistency and diversity of whole-home outcomes. These include enhanced comfort, convenience, reduced costs, and lower environmental impact based on input from the homeowner. The software accounts for time-of-use rates and is compatible with smart products from any manufacturer.

Arrangements for communicating data in a computing system using multiple processors

Systems and methods for reducing data movement in a computer system. The systems and methods use information or knowledge about the structure of an algorithm, operations to be executed at a receiving processing unit, variables or subsets or groups of variables in a distributed algorithm, or other forms of contextual information, for reducing the number of bits transmitted from at least one transmitting processing unit to at least one receiving processing unit or storage device.
