An intensity-based external cavity sensor comprises an input fiber which is a single mode fiber. An optical bandpass filter is deposited at the end of the single mode fiber. A reflector is also provided at the end of the wire.

Abstract: A radio frequency transmission line filter has an insulative substrate substantially in the form of a plate of dielectric material, a ground plane formed by metallization on one face of the substrate, capacitor plates formed by areas of metallization on the other face of the substrate to form, in conjunction with the ground plane, capacitances, and coupled to the capacitances, respective metallized short circuit transmission line stubs forming inductances. The inductances and capacitances together form transmission line resonators. To allow the designer a wide choice in capacitance and/or inductance values, the substrate is recessed in selected areas to bring the ground plane to within predetermined distances of the capacitor plates or inductance stubs. The ground plane may be trimmed in the recessed areas to adjust component values.

Abstract: An insert plate is embedded in an air bag cover, and is provided with an insert supporting portion, a pair of insert expanding portions and a coupling portion for coupling the insert expanding portions. Notches are provided in the insert supporting portion on both sides of the coupling portion. Terminals of a H-shaped rupture portion are positioned on inclined surfaces of the insert supporting portion. Accordingly, when the air bag cover expands due to a vehicle decelerating rapidly, a rupture is generated along the inclined surfaces, and an expansion occurs with a position offset by the notches as an expansion center line. Therefore, the air bag cover can be ruptured along a predetermined rupture line, and expand to the maximum.
