In this paper, we study a two-phase underlay cognitive relay network, where there exists an eavesdropper who can overhear the message. The secure data transmission from the secondary source to ...

This paper presents an LC passive wireless sensor for monitoring both humidity and pressure by using a relay switch. The LC sensor system consists of an inductor, two capacitors, and a relay switch.

Power relays are specifically designed to handle either AC or DC. It’s important to know the fundamental differences between them before building them into a system.

Extensive product groups include relays, switches, connectors, MEMS flow sensors, pressure sensors, and optical components.
