Abstract: A system and process for direct lithium extraction from geothermal brines, and more particular to the sequential combination of a binary cycle geothermal plant, a direct lithium extraction circuit, a lithium chloride concentration and purification circuit, and a lithium battery chemical processing circuit, for the production of battery-quality lithium hydroxide monohydrate, lithium carbonate or both from geothermal brines. The processing circuits are powered by the electricity and heat produced by the binary cycle geothermal plant without the use of carbon-based fuels. Non-condensable gases that may come out of solution from the geothermal brine are not emitted into the atmosphere.

Abstract: Systems and methods for sonifying electrical signals obtained from a living subject, particularly EEG signals, are disclosed. A time-domain signal representing the activity of an organ is obtained. A voltage of the time-domain signal over a time block is determined. An acoustic signal based on the time-domain signal over the time block is produced. The acoustic signal comprises one or more audibly discernible variations representative of the activity of the organ. If the determined voltage is over a threshold voltage, the time-domain signal is squelched over at least a portion of the time-block as the acoustic signal is produced. The time-domain signal can be squelched by ramping down the signal as an input to produce the acoustic signal. The frequency spectrum of the acoustic signal can also be adjusted as it is produced, such as by flattening the signal and/or attenuating high frequencies along the frequency spectrum of the signal.

Abstract: The present disclosure provides systems and methods for seizure detection. The method for seizure detection may include receiving a plurality of electroencephalography (EEG) signals over a plurality of channels for a subject, preprocessing the plurality of EEG signals by segmenting the plurality of EEG signals for each channel into a plurality of temporal data segments, extracting a plurality of features from each temporal data segment for each channel, and applying a machine learning algorithm to the plurality of features to perform a seizure binary classification for each temporal data segment for each channel. A control policy may be employed to determine a seizure burden on the aggregated seizure binary classifications. When the seizure burden is equal to or exceeds a threshold, a notification may be generated. The notification may be usable by a healthcare practitioner to assess whether the subject may be at risk of having a seizure.

Abstract: A method of minimizing kogation of a heater element in a thermal inkjet printhead. The method includes the steps of: (i) supplying an inkjet ink to a nozzle chamber of the printhead; and (ii) repeatedly actuating a heater element in the nozzle chamber so as to heat a portion of the ink to a temperature sufficient to form a bubble therein, thereby causing droplets of ink to be ejected from a nozzle opening associated with the nozzle chamber. The ink includes a styrene-acrylic copolymer having a glass transition temperature (Tg) in the range of 5 to 30° C. and acid value in the range of 100 180 mgKOH/g, said styrene-acrylic copolymer minimizes kogation of the heater element.
