A non-common-ground bandpass filter circuit with electrostatic discharge (ESD) protection is disclosed. The non-common-ground bandpass filter circuit with ESD protection includes a non-common-ground plane, a dielectric substrate and a conductor. The conductor is disposed above the non-common-ground plane. The dielectric substrate is disposed between the conductor and the non-common-ground plane. The non-common-ground plane at least has a first ground region and a second ground region separated and insulated from each other. The first ground region corresponds to a first terminal of the conductor and the second ground region corresponds to a second terminal of the conductor. When an ESD event occurs on one of the first ground region and the second ground region, the other of the first ground region and the second ground region will not be damaged by the ESD event. The non-common-ground bandpass filter circuit also provides surge protection.

A positioning and tracking system is disclosed. The positioning and tracking system includes positioning sensors disposed in a space, wherein the positioning sensors are all movable and all have functions of sensing distance, angle and time, and the positioning sensors communicate with each other to sense relative distances, relative angles and relative times between every two positioning sensors of the positioning sensors. when at least one of the positioning sensors moves in the space, the positioning sensors re-communicate with each other to instantly update the relative distances, the relative angles and the relative times between every two positioning sensors of the positioning sensors.
