  • Patent number: 11914572
    Abstract: Technologies are described providing adaptive query routing in a replicated database environment. The technologies can be used with a variety of replication protocols. Prepared statements, such as for queries, from a database client can be routed to a source node, or a source node and available replica nodes, when a replica node becomes unavailable. When a replica node becomes available again, a prepared statement can be updated to indicate that the updated prepared statement can be executed at nodes including the replica node that is available again. Prepared statement routing can also be used when a portion of replicated data becomes unavailable at a replica node, but a portion of replicated data remains available.

  • Publication number: 20240017075
    Abstract: Devices and methods to effectuate waveform distortion adjusted stimulation therapy of tissue, based on an inverse model of the tissue, are disclosed. In some aspects a linear model of an electrode used to delivery therapy and of the tissue is determined. Parameter values of the linear model may be determined based on measuring voltage feedback during application of stimulation and/or measurement waveforms. The parameter values of the linear model of the electrode and tissue may be used to determine a forward model of the electrical response of the tissue. From the forward model, an inverse model of the tissue may be determined and the inverse model can be used to modify or filter a stimulation waveform to reduce waveform distortion caused by tissue, such as tissue primitive and/or tissue capacitance. Accordingly, providing therapy with the filtered waveform may have increased efficacy by accounting for and adjusting for waveform distortion.
