The transistor count is the number of transistors in an electronic device. It typically refers to the number of MOSFETs on an integrated circuit (IC) chip, as all modern ICs use MOSFETs. It is the most common measure of IC complexity. The rate at which MOS transistor counts have increased generally follows Moore's law, which observed that the transistor count doubles approximately every two years.

People living with HIV/AIDS face increased challenges in maintaining proper nutrition. Despite developments in medical treatment, nutrition remains a key component in managing this condition. The challenges that those living with HIV/AIDS face can be the result of the viral infection itself or from the effects of anti-HIV therapy (HAART).
The first hearing aid was created in the 17th century. The movement toward modern hearing aids began with the creation of the telephone, and the first electric hearing aid was created in 1898. By the late 20th century, the digital hearing aid was distributed to the public commercially. Some of the first hearing aids were external hearing aids. External hearing aids directed sounds in front of the ear and blocked all other noises. The apparatus would fit behind or in the ear.
Norman (Norm) B. Krim (1913–2011) was an American electronics engineer and engineering executive. His drive to create a transistor product for the electronics experimenter-hobbyist market contributed to paving the path for a generation of American electronics engineers and technicians during the Space Race between the United States and the Soviet Union.
Transistor laser is a semiconductor device that functions as a transistor with an electrical output and an optical output as opposed to the typical two electrical outputs. This optical output separates it from typical transistors and, because optical signals travel faster than electrical signals, has the potential to speed up computing immensely. Researchers who discovered the transistor laser developed a new model of Kirchhoff's current law to better model the behavior of simultaneous optical and electrical output.
Eargo is an American hearing aid manufacturer based in San Jose, California. The company's hearing aids were inspired in their design by a fishing fly. Each unit is also rechargeable.
