  • Publication number: 20240110884
    Abstract: As one example, an apparatus includes a dielectric microsensor having a microfluidic chamber that includes a capacitive sensing structure. The microfluidic chamber is adapted to receive a volume of a blood sample, and a bioactive agent is adapted to interact with the blood sample, as a sample under test (SUT), within the microfluidic chamber. A transmitter can provide an input radio frequency (RF) signal to the dielectric microsensor, and a receiver can receive an output RF signal from the dielectric microsensor. A computing device is configured to compute dielectric permittivity values for the SUT based on the output RF signal over a time interval in which the dielectric permittivity values are representative of the bioactive agent interacting with the blood sample over the time interval. The computing device is further configured to provide a readout representative of hemostatic dysfunction for the blood sample based on the dielectric permittivity values.

    Abstract: Methods for bridging brain sites between which there is substantially no effective communication, and associated neural prosthetic devices, are provided. A neural spike in a first neural site in a subject is detected, and a stimulus to a second neural site in the subject is delivered within a defined period of time after the detection of the neural spike, wherein there is substantially no effective communication between the first and second neural sites. The method forms an artificial bridge between the two neural sites, and establishes lasting communication between the two sites. The present disclosure provides, among other things, a neural prosthetic device comprising an integrated circuit that comprises a recording front-end comprising a plurality of recording channels; a processor unit; and a stimulus delivering back-end comprising a plurality of stimulation channels.

  • Patent number: 8812165
    Abstract: Various embodiments are directed to systems and methods for optimizing energy use with one or more optimization engine objects. An optimization engine object may have a plurality of dependent objects including at least a dependent optimization engine object, or at least one of a supply-side or demand-side object. The optimization engine object may receive dependent object attribute data from each of the at least one dependent objects; determine an optimal configuration for the plurality of dependent objects over the first time period subject to at least one optimization constraint; and conditioned upon the optimization engine depending from a superior optimization engine, transmit a net energy usage associated with the optimal configuration to the superior optimization engine.
