Abstract: An electronic device that detects and analyzes the energy emitted by brains of individuals. This device measures and analyzes the energy emitted from the brain activity of, for example, students, enabling the classification of students with learning difficulties based on the quantity of emitted energy. Leveraging established measuring devices, supported by computer programs akin to those utilized in electrocardiography, enables the prediction of both the quantity and speed of brain energy based on the magnetic field's intensity. By comparing the intensity of the magnetic field resulting from electrochemical energy in the brain with standard measurements for the general populace, learning difficulties can be diagnosed effectively.

The hexagonal meandered slot symmetrically includes six legs of equal length and six vertexes. The capacitor is switchably connected to the metallic layer. The first feed horn is connected by a first feed line to a first edge of the front side of the circuit board. The second feed horn is connected by a second feed line to a second edge of the front side of the circuit board.

Abstract: A method for producing a core-shell capsule for delivering a therapeutic agent is provided. The method includes printing a composite material via a nozzle on a substrate while moving the nozzle in a pre-designed pattern to create the shell of a hollow capsule. The shell defines a cavity within the hollow capsule, and the shell has an opening at an apex of an outer surface of the shell. The method includes introducing a composition, in liquid form, containing the therapeutic agent at a temperature of at least 45° C. into the cavity of the hollow capsule via the opening of the shell, and naturally cooling the composition inside the shell to solidify the composition and adhere the composition to an inner surface of the shell thereby forming a core of the core-shell capsule.

Abstract: The present disclosure relates to pipeline corrosion inhibitor optimization and control. In an example, a failure probability representative of a likelihood of a pipeline corrosion failure and a consequence level representative of a consequence from the pipeline corrosion failure can be computed. A risk matrix can be generated and used to identify an inhibitor concentration based on the failure probability and consequence. A dosage of a corrosion inhibitor for mitigating corrosion of a pipeline can be computed based on the inhibitor concentration. In some examples, the dosage of the corrosion inhibitor can be adjusted based on a modification factor computed at least based on a corrosion rate measured for the pipeline.

Abstract: A fingerprint scanner for capturing fingerprints of infant children is described. The fingerprint scanner includes a transparent tube configured for an infant child hand and an array of camera sensors spaced apart on the transparent tube so that each camera sensor captures an overlapping part of an image captured by its neighboring camera sensor. The array of camera sensors is arranged below a surface, along a periphery of a circumference and substantially along a length of the transparent tube up to a processor compartment. The fingerprint scanner also includes a processing circuitry configured to: simultaneously receive multiple images from the array of camera sensors, and process the multiple images including merging the multiple images to remove overlapping portions and recover a single image of the infant child's fingertips and palm.

Abstract: A method is presented for predicting onset of pulmonary congestion symptoms. The overall idea is to track rising left ventricular filling pressure (LVFP) in heart failure patients by exploiting significant changes in a pulsatile arterial waveform obtained with a mobile device and thereby avert hospitalizations. The stimulus for the changes may be metronomic deep breathing performed by the patient or a natural occurring arrhythmia such as atrial fibrillation or premature beats. For either stimulus, the extent of the amplitude variations depends on where the patient is on the Starling curve. If the patient is on the steep part of the curve, the variations will be large and LVFP will be low. If the patient is on the flatter part of the curve, the variations will be smaller and LFVP will be higher. These variations can be normalized in various ways to arrive at a congestion prediction index (CPI).
