SAW filters are electronic filters that are designed and manufactured using surface acoustic wave (SAW) technology.

IC electronic filters are frequency-selective circuits that consist of devices such resistors, capacitors, inductors, transistors, or operational amplifiers coupled with reactive components.

Specialty microscopes are designed for specific applications such as metallurgy or gemology.

RF filters and microwave filters are devices that pass or reject signals by frequency.

Resonators are frequency-selective electronic circuits that can produce a fixed (resonant) frequency when properly excited.

Touch screen displays are user-friendly input devices.

Touch screen sensors are composed of a transparent touch surface surrounded by a sensor array that provides positional information to a processor
