Abstract: A system and method for appliance communication is provided. The method includes connecting an initially-connected device to a server via a network; initiating, at a first appliance, a first appliance registration process; detecting, via the first appliance, a communications signal from a second appliance; communicatively coupling the second appliance to the server via the initially-connected device; and transmitting second appliance registration data from the second appliance to the server via communicative coupling of the second appliance to the initially-connected device connected to the network.

Abstract: Disclosed herein is a pattern recognition and feature extraction system and method configured to detect and analyze non-stationary, transient, or locally structured signals from longer time-series data of obtained beta waveforms of an animal to characterize a biomarker of a brain state or condition. An example system comprises a computing device configured to process obtained recordings of electrical activity arising from a brain of an animal for detecting beta wave events. A first representation of short-time segments may be generated to represent amplitude fluctuations indicating extrema and time-domain features in the beta wave events and a second representation for identifying temporal positions of the extrema in the first representation. The computing device compares statistical distributions of feature characteristics and generates mean waveforms of signals from at least one condition aligned by the temporal positions assigned to one of extracted feature types to indicate a brain state of the animal.

Abstract: The present invention provides a dehydrogenase mutant L283V/L286V, and a preparation method and use thereof, and relates to the field of biomedicine technologies. An amino acid sequence of the mutant L283V/L286V is as shown in SEQ ID NO: 1; and the mutant is prepared by simultaneously mutating 283rd and 286th leucine of a dehydrogenase with an amino acid sequence as shown in SEQ ID NO: 3 into valine. The dehydrogenase mutant L283V/L286V shows high selectivity in catalyzing myosmine reduction reaction in a whole cell system to produce S-nornicotine, and has relatively high dehydrogenase and imine reductase activities, a short enzyme reduction time, and a high transformation rate. The product S-nornicotine obtained through the reaction has extremely high optical purity, which reduces the operation difficulty of subsequent purification.

Abstract: A laundry treatment appliance includes a cabinet, a door to selectively open and close the cabinet, a tub mounted within the cabinet, a drum rotatably mounted within the tub, an air circulation duct provided in the cabinet and having a first end connected to an air outlet of the tub and a second end connected to an air inlet of the tub, and a filter provided within the air circulation duct. The filter defines a cool air end having a perimeter thereof attached to an interior wall of the circulation duct and a warm air end having a perimeter thereof spaced apart from the interior wall of the circulation duct, and the second end is positioned below the first end in a vertical direction.

Abstract: A flexible circuit electrode array with more than one layer of metal traces comprising: a polymer base layer; more than one layer of metal traces, separated by polymer layers, deposited on the polymer base layer, including electrodes suitable to stimulate neural tissue; and a polymer top layer deposited on the polymer base layer and the metal traces. Polymer materials are useful as electrode array bodies for neural stimulation. They are particularly useful for retinal stimulation to create artificial vision, cochlear stimulation to create artificial hearing, or cortical stimulation many purposes. The pressure applied against the retina, or other neural tissue, by an electrode array is critical. Too little pressure causes increased electrical resistance, along with electric field dispersion. Too much pressure may block blood flow.

Abstract: The invention is directed to a method of bonding a hermetically sealed electronics package to an electrode or a flexible circuit and the resulting electronics package, that is suitable for implantation in living tissue, such as for a retinal or cortical electrode array to enable restoration of sight to certain non-sighted individuals. The hermetically sealed electronics package is directly bonded to the flex circuit or electrode by electroplating a biocompatible material, such as platinum or gold, effectively forming a studbump connection, which bonds the flex circuit to the electronics package. The resulting electronic device is biocompatible and is suitable for long-term implantation in living tissue.
