7. The expanding-controllable airbag system as defined in claim 6, wherein a protrusion that is inserted in the mounting groove is formed at the proximate portion of the guide member.
8. The expanding-controllable airbag system as defined in claim 1, wherein an inlet portion of the cushion is connected to the entire edges of the opening of the expansion pressure control member and a mid-portion of the cushion is connected with a free distal end portion of the guide member.
9. The expanding-controllable airbag system as defined in claim 1, wherein the diffuser is disposed at a bottom in a crush pad and the guide member is disposed adjacent to a rear side of the crash pad.
10. An expanding-controllable airbag system comprising:
a diffuser having at least a gas supply hole, at least a gas discharge hole, and an inflator;
an expansion pressure control member movably disposed with respect to the diffuser and having at least an opening fluidly-communicating the gas supply holes and a closing portion opening and closing the gas discharge holes; and
a guide member connected with the expansion pressure control member, being installed outside of a cushion, guiding the cushion in a predetermined direction by contacting an outside surface of the cushion, and controlling the opening and closing of the gas discharge holes by moving the expansion pressure control member with respect to the diffuser using an external force or an internal force applied while the cushion expands.
11. The expanding-controllable airbag system of claim 10, wherein the external force is applied by an inertia force of a passenger after a collision of a vehicle occurs.
12. The expanding-controllable airbag system of claim 10, wherein the internal force is applied by the cushion as the cushion expands after a collision of a vehicle occurs.
13. The expanding-controllable airbag system as defined in claim 10, wherein the diffuser has a cylindrical shape, and the gas supply holes and gas discharge holes are axially arranged in a plurality of rows along the circumference of the diffuser.
14. The expanding-controllable airbag system as defined in claim 10, wherein guide grooves are formed at both distal end portions of the diffuser to receive and movably support both distal end portions of the expansion pressure control member.
15. The expanding-controllable airbag system as defined in claim 10, wherein the expansion pressure control member is an arc-shaped plate and has a mounting groove to receive a proximate end portion of the guide member.
16. The expanding-controllable airbag system as defined in claim 15, wherein a protrusion that is inserted in the mounting groove is formed at the proximate portion of the guide member.
17. The expanding-controllable airbag system as defined in claim 10, wherein an inlet portion of the cushion is connected to the entire edges of the opening of the expansion pressure control member and a mid-portion of the cushion is connected with a free distal end portion of the guide member.
18. The expanding-controllable airbag system as defined in claim 10, wherein the diffuser is disposed at a bottom in a crush pad and the guide member is disposed adjacent to a rear side of the crush pad.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An ion acoustic remote substance identification and location system, comprising:
a. an ion acoustic voltage radiation source;
b. means for ionizing an intermediate chemical to produce a probing signal of a desired frequency and amplitude capable of propagating a voltage from said ion acoustic voltage radiation source to a desired target substance to produce non-destructive molecular resonance therein;
c. means to transmit said voltage and said probing signal to a target substance to cause said target substance to undergo molecular resonance and produce a characteristic electrical response signal;
d. an IR detector for detecting said electrical response signal from said target substance, said IR detector includes one or more infrared emitters that produce a beam of IR radiation that is transmitted to a target substance, said outer housing also including an electrode used to detect a response signal from said target substance;
e. a transformer assembly attached to said electrode, said transform assembly includes a metallic outer housing;
f. an artificial grounding device connected to said IR detector and said transformer assembly, said artificial grounding device includes an IR emitter diode that produces a IR signal when a current is applied thereto, said artificial grounding device also including an opaque, insulative shield that is slightly smaller than said outer housing thereby creating a gap through which said IR signal from said IR emitter diode may be transmit to ionize the air; and,
g. means to identify said target substance based on said electrical response signal detected by said IR detector.
