Sensor unit
First Claim
Patent Images
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, andwherein the lattice type radiation surface has one or more radiation surfaces configured to have one or more different radiation angles.

6. A sensor unit, comprising:
-
a casing in which a space is formed therein; a mounting portion fixed on one side of the space inside the casing 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 disposed on the second end of the elastic member and configured to transmit a detectable signal at different angles; a reflection body disposed on the other side of the space inside the casing relative to the mounting portion; a reception portion that is disposed inside the casing and configured to receive the detectable signal that is reflected from the reflection body; and a controller configured to determine whether the reflected signal indicates an impact, motion, or impending impact. - View Dependent Claims (7, 8)

9. A sensor unit, comprising:
-
a mounting portion fixed on one side on an interior wall of a vehicle; an elastic member of which one end thereof is fixed on the mounting portion; a transmission portion that is disposed at the other end of the elastic member to radiate a predetermined frequency length at different angles; a reception portion that receives the frequency length reflected from other random object; and a control portion that determines whether it is an abnormal condition according to the characteristics of the frequency length that is received by the reception portion. - View Dependent Claims (10)
