Claim Text:
1. A sensor unit, comprising: a mounting portion fixed on one side of the sensor unit on an interior wall of a vehicle; an elastic member including a first end and a second end, the first end being disposed on the mounting portion; a transmission portion configured to transmit a detectable signal, the transmission portion disposed on the second end of the elastic member; a reception portion configured to receive a reflection of the detectable signal; and a controller that determines whether the reflected signal indicates an impact, motion, or impending impact, wherein the transmission portion includes an infrared LED that transmits an infrared signal, a transmission signal processing controller that modulates the infrared signal, and a LED driver that adjusts the modulated infrared signal of the transmission signal processing control portion and transmits the infrared signal via the infrared LED, wherein the LED driver and the infrared LED transfer the infrared signal through the elastic member, wherein a radiation surface of the transmission portion is a lattice type, and wherein the lattice type radiation surface has one or more radiation surfaces configured to have one or more different radiation angles.
