Electronic

Cathode-ray tube, originally developed for displaying electrical waveforms on a screen for engineering measurements, evolved into the television picture tube. Such tubes operate by forming the electrons emitted from the cathode into a thin beam that impinges on a fluorescent screen at the end of the tube. Deflecting the electron beam causes patterns of light to be produced on the screen, creating the desired optical images.

The subject covers a broad spectrum, from the design and development of an electronic system to assuring its proper function, service life and disposal. Electronic systems design is therefore the process of defining and developing complex electronic devices to satisfy specified requirements of the user. The first working point-contact transistor was invented by John Bardeen and Walter Houser Brattain at Bell Labs in 1947. In April 1955, the IBM 608 was the first IBM product to use transistor circuits without any vacuum tubes and is believed to be the first all-transistorized calculator to be manufactured for the commercial market. Thomas J. Watson Jr. ordered all future IBM products to use transistors in their design. From that time on transistors were almost exclusively used for computer logic and peripherals.

The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small electrical signals, inaugurated the field of electronics and the electron age. Practical applications started with the invention of the diode by Ambrose Fleming and the triode by Lee De Forest in the early 1900s, which made the detection of small electrical voltages such as radio signals from an radio antenna possible with a non-mechanical device. The growth of electronics was rapid, and by the early 1920s commercial radio broadcasting and communications were becoming widespread, and electronic amplifiers were being used in such diverse applications as long distance telephony and the music recording industry. Tasos Stamou is a musician and instrument maker who hacks, or “circuit bends,” old toys and electronic devices to make far-out musical gizmos. If you have dreams of bringing up your kid to be the next Dan Deacon, any of these would be a good place to start. Emotion recognition is actively used in brain–computer interface, health care, security, e-commerce, education and entertainment applications to increase and control human–machine interaction.

Circuit Bending

Resulted by suspended particles scattering and wavelength-dependent light attenuation, underwater images are always hazy and color-distorted. This paper is focused on a design of a high-voltage generator, which is proposed for a high-frequency irreversible electroporation (H-FIRE). Most HV sources used for cell electroporation are based on a controlled discharge of [...] Read more.

Electroencephalogram signals are one such source to capture and study human emotions. In this Letter, a novel time-order representation based on the S-transform and convolutional neural network is proposed for the identification of human emotions. EEG signals are transformed into time-order representation based on the S-transform. This TOR is given as an input to CNN to automatically extract and classify the deep features. Emotional states of happiness, fear, sadness, and relax are classified with an accuracy of 94.58%. The superiority of the method is judged by evaluating four performance parameters and comparing it with existing state-of-the-art on the same dataset.
