1. A method for manufacturing a structural panel, the method comprising:
positioning a first flange portion of a first stiffener at least proximate to a second flange portion of a second stiffener to form an at least approximately continuous support surface extending transversely relative to lengths of the first and second stiffeners between a first raised portion of the first stiffener and a second raised portion of the second stiffener;
mating at least the first flange portion of the first stiffener to a skin, the-first raised portion projecting away from the skin;
mating at least the second flange portion of the second stiffener to the skin, the second raised portion projecting away from the skin;
positioning a base portion of a support member in contact with the approximately continuous support surface; and
mating the base portion of the support member to the first flange portion of the first stiffener and the second flange portion of the second stiffener without mating the base portion to the skin between the first raised portion of the first stiffener and the second raised portion of the second stiffener.
2. The method of claim 1, further comprising manufacturing the support member from composite materials.
3. The method of claim 1, further comprising manufacturing the skin and the first and second stiffeners from composite materials.
4. The method of claim 1 wherein mating at least a first flange portion of a first stiffener to a skin includes adhesively bonding the first flange portion of the first stiffener to the skin, and wherein mating at least a second flange portion of a second stiffener to the skin includes adhesively bonding the second flange portion of the second stiffener to the skin.
5. The method of claim 1 wherein mating at least a first flange portion of a first stiffener to a skin includes adhesively bonding the first flange portion of the first stiffener to the skin, wherein mating at least a second flange portion of a second stiffener to the skin includes adhesively bonding the second flange portion of the second stiffener to the skin, and wherein mating a base portion of a support member to the first flange portion of the first stiffener and the second flange portion of the second stiffener includes adhesively bonding the base portion to the first and second flange portions.
6. The method of claim 1 wherein mating at least a first flange portion of a first stiffener to a skin and mating at least a second flange portion of a second stiffener to the skin includes co-curing the first stiffener, the second stiffener, and the skin to bond the first and second flange portions to the skin.
7. The method of claim 1 wherein the support member is a first frame section, and wherein the method further comprises attaching a second frame section to the first frame section.
8. The method of claim 1 wherein the support member is a first frame section, and wherein the method further comprises attaching a second frame section to the first frame section after mating the base portion of the first frame section to the first flange portion of the first stiffener and the second flange portion of the second stiffener.
9. The method of claim 1 wherein the support member is a first frame section further including an upstanding portion projecting away from the base portion, and wherein the method further comprises attaching a second frame section to the upstanding portion of the first frame section.
10. The method of claim 1 wherein the support member is a first frame section further including an upstanding portion projecting away from the base portion, and wherein the method further comprises attaching a second frame section to the upstanding portion of the first frame section, the second frame section having a C-shaped cross-section.
11. A method for manufacturing a structural panel, the method comprising:
positioning a first flange portion of a first stiffener on a skin, the first stiffener including a first raised portion projecting away from the skin, the first flange portion extending outwardly from the first raised portion in a first direction transverse to a length of the first stiffener; positioning a second flange portion of a second stiffener at least proximate to the first flange portion of the first stiffener, the second stiffener including a second raised portion projecting away from the skin, the second flange portion extending outwardly from the second raised portion in a second direction transverse to a length of the second stiffener to form an at least approximately continuous support surface extending transversely between the first raised portion of the first stiffener and the second raised portion of the second stiffener; and mating a base portion of a support member to the at least approximately continuous support surface without mating the base portion to the skin between the first raised portion of the first stiffener and the second raised portion of the second stiffener.
12. The method of claim 11, further comprising manufacturing the support member from composite materials.
13. The method of claim 11, further comprising:
positioning a first opening in the support member around the first raised portion of
the first stiffener; and
positioning a second opening in the support member around the second raised portion of the second stiffener.
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 apparatus comprising:
a vibration barrel comprising:
a vibration motor;
a power source for the vibration motor;
an exterior elastomeric band consisting of
a vibration barrel case that houses the vibrator barrel within the vibration barrel case; and
a flat loop;
wherein the longitudinal axis of the flat loop and the longitudinal axis of the vibration barrel case retaining the vibration barrel are parallel and spaced apart;
the vibration barrel is further comprised of a plurality of battery cells;
a switching means for engaging only one battery cell for lower rates of vibration and engaging two battery cells for higher rates of vibration;
the switching means further comprises a protrusion for:
contacting a first metal strip that causes current to flow from a first battery to the vibration motor resulting in the vibration of the apparatus under the power of one battery; and
contacting a second metal piece that causes current to flow from a first battery to the vibration motor and from a second battery to the vibration motor resulting in the vibration of the apparatus under the power of two batteries.
2. The apparatus of claim 1 further comprising means to regulate the rate of vibration by drawing lower battery power for lower rates of vibration and higher battery power for higher rates of vibration.
3. The apparatus of claim 1 wherein the vibration barrel is further comprised of a latch door for battery interchange.
4. The apparatus of claim 2 wherein the vibration barrel is further comprised of a vibration barrel with a-latch door for battery interchange.
