Positron emission tomography (PET) is a medical imaging technique that visualizes metabolic and biochemical processes in the human body. It involves injecting a small amount of radioactive material (radiotracer) into the patient, which emits positrons. When positrons collide with electrons, they produce gamma rays, which are detected by a PET scanner. The resulting images provide detailed information about organ function, aiding in the diagnosis and monitoring of various diseases, including cancer.

Sound reinforcement systems are a combination of various equipment, such as microphones, pro speakers, audio mixers, audio signal processors, and power amplifiers. These systems are designed and engineered to capture, enhance, and amplify the live or pre-recorded sound and distribute it over a large area to an audience. It aims to deliver amplified sound to large or distant audiences while retaining the existing audio quality and ensuring that the sound is not directed to non-listened areas. It also transmits audio to remote locations through AV conferences or recording or streaming.

A smart sensor has a multi-sensing capability that is widely used to measure the temperature, pressure, humidity, and position and processes the collected data using microprocessors and advanced computation models. Smart sensors enable accurate as well as automated collection of data.

A small signal transistor is a device with three connections and is capable of amplification and rectification. Transistors are solid-state devices used for amplifying, controlling, and generating signals.

A pupillometer is a medical device used to measure the size and reactivity of the pupil, often in response to light stimuli. It provides precise, objective data on pupil diameter, symmetry, and dynamics, which are critical indicators of neurological function, ocular health, and autonomic nervous system activity. Pupillometers are widely used in ophthalmology, neurology, anesthesiology, and emergency medicine.
