1. A multi-hull boat comprising two hulls, each hull having a buoyancy section, a deck disposed upon said hulls, a frame supporting said deck and connected to said hulls, said frame being extendable relative to said deck for shifting said hulls between a laterally extended position and laterally retracted position, a drive connected to said frame for shifting said hulls between their said extended and retracted positions, a deck component connected to said frame and being shiftable with the frame between inward and outward positions relative to said deck, said deck having a slot, said component including a support part extending through and above said deck at said slot, said support part forming a seat and being connected to said frame and shiftable along said slot as said hulls are shifted between their extended and retracted positions.
2. The boat of claim 1 wherein said drive is a ball recirculating drive and includes a motor for actuating the ball recirculating drive.
3. The boat of claim 1 wherein said deck is located between said deck component and said frame.
4. A multi-hull boat comprising two hulls, each hull having a buoyancy section, each said buoyancy section of each hull including a bow section and a separate stern section, a deck disposed upon said hulls, a first frame supporting said deck and connected to said bow section of each hull, a fixed frame supporting said deck and connected to the stern section of each hull, said first frame being extendable relative to said deck for shifting said bow sections of said hulls relative to the stern sections between a laterally extended position and laterally retracted position, a drive connected to said first frame for shifting said bow sections of said hulls between their said extended and retracted positions.
5. A multi-hull boat comprising two hulls, each hull having a buoyancy section, each said buoyancy section of each hull including a bow section and a separate stern section, a deck disposed upon said hulls, a shiftable frame supporting said deck and connected to said bow section of each hull, a fixed frame supporting said deck and connected to the stern section of each hull, said shiftable frame being extendable relative to said deck for shifting said bow sections of said hulls relative to said stern sections between an outwardly extended position laterally offset from said stern sections and a retracted position aligned with said stern sections, a drive connected to said shiftable frame for shifting said bow sections of said hulls between their extended and retracted positions.
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. A TEM coil providing MR imaging, comprising:
a coil providing at least two head restraints; said head restraints having a means for audio communication to a subject; and
said head restraints having a means for active or passive protection for a subject’s hearing.
2. The TEM coil of claim 1, further comprising a head cushion to provide a three-point head restraint.
3. The TEM coil of claim 1, further comprising a means to secure said head restraints to a subject’s head.
4. The TEM coil of claim 1, further comprising a means to accept an audio signal input.
5. The TEM coil of claim 1, wherein the means for audio communication provides active noise suppression.
