Fabrication, methods, apparatuses, and systems for ultra-compliant probes for neural and other tissues
Methods, systems and apparatuses of ultra-miniature, ultra-compliant probe arrays that allows for design flexibility to match the stiffness of the tissue it is being applied to, such as the brain tissue, in all three axes (x, y and z), with interconnect cross section smaller than cell dimensions. Stiffness matching requires specific geometric and fabrication approaches, commonly leading to ultra-thin probe wires. Sizing of the electrodes for specific cell dimensions reduces glial formation. Further reduction in stiffness is obtained by incorporating different geometric features to the electrode, such as meandering the electrode wires. The small thickness and geometric features of the wires commonly result in very high compliance. To enable effective insertion of the probes to the tissue, the present invention uses stiff biodisolvable and/or biodegradable polymers, including single use or combinations of carboxymethyl cellulose, polyvinylpyrrolidone, polyvinyl alcohol, maltose, other sugar molecules, polylactic acid and its co-polymers. |

Adaptive synchronous protocol for minimizing latency in TDD systems
Systems and methods are presented that offer significant improvements in the performance of time division duplex (TDD) systems by utilizing an adaptive synchronous protocol. Conventional TDD systems are limited because data is transmitted during discreet and limited intervals of time, and because TDD transceivers may not simultaneously transmit and receive for reasons of insufficiently separated frequencies and limited receiver selectivity. Typically, TDD systems have significant latency due to the time to change from transmission to reception and the propagation delay time. By synchronizing the master nodes and the one or more remotes and by scheduling the traffic loads between these nodes, remote nodes may begin transmitting before the master node is finished with its transmission, and vice versa. This method reduces latency and improves the frame efficiency. Further, the frame efficiency may improve as the distance from the master node to the remote node increases. |

In response to detecting the failure, the upstream PORT routing element determines a set of candidate interfaces that are also coupled to the downstream PORT routing element. The upstream PORT routing element selects a new interface from the set of candidate interfaces and installs the new interface as a replacement forwarding interface for the multicast datastream. |
