Systems and methods for reducing latency through motion estimation and compensation techniques are disclosed.

Cluster creation using self-aware, self-joining cluster nodes
Disclosed embodiments provide cluster creation using self-joining cluster nodes. Each node within a cluster is assigned a role of master or non-master. A master node initializes and creates a cluster. A non-master, or “role” node initializes and joins a cluster established by the master. If the master has not yet initialized, the non-master node waits until the master node is operational and then joins the cluster. A description file associated with each node describes the services and configuration required for the node's assigned role. In this way, non-master nodes can be spawned independently of the master node, providing a greater level of scalability, improved fault tolerance, and increased availability. |

Light is modulated at a source to encode data. An additional tracking signal is imposed on the light using polarization modulation (PM). PM modulates one or more values of polarization rotation or polarization ellipticity of the light. These values may be dithered within constraints to provide a specified modulation index at the optical receiver, without impairing the encoded data. At the optical receiver, a polarization analyzer is used to recover the tracking signal, converting the polarization modulation to amplitude modulation. For example, after the light passes through the analyzer, an array of optical photodetectors detects the changes in apparent intensity resulting in the interaction between the light and the analyzer that correspond to the tracking signal. Due to a high modulation index, the recovered signal exhibits a high signal to noise ratio (SNR). The high SNR improves a noise equivalent angle, improving tracking performance. |

Redox-flow batteries employing oligomeric organic active materials and size-selective microporous polymer membranes
Intermittent energy sources, including solar and wind, require scalable, low-cost, multi-hour energy storage solutions to be effectively incorporated into the grid. Redox-flow batteries offer a solution, but suffer from rapid capacity fade and low Coulombic efficiency due to the high permeability of redox-active species across the battery's membrane. Here we show that active-species crossover can be arrested by scaling the membrane's pore size to molecular dimensions and in turn increasing the size of the active material to be above the membrane's pore-size exclusion limit. When oligomeric redox-active organic molecules were paired with microporous polymer membranes, the rate of active-material crossover was either completely blocked or slowed more than 9,000-fold compared to traditional separators at minimal cost to ionic conductivity. In the case of the latter, this corresponds to an absolute rate of ROM crossover of less than 3 μmol cm−2 day−1 (for a 1.0 M concentration gradient), which exceeds performance targets recently set forth by the battery industry. This strategy was generalizable to both high and low-potential ROMs in a variety of electrolytes, highlighting the importance of macromolecular design in implementing next-generation redox-flow batteries. |
