Neuropatía diabética In one example, the first side 1321 a may include a parabolic shape while the second side 1321 b includes a flat surface, such as the flat surface shown on displacement vessel 1202 sides 1221 a and 1221 b in FIGS. FIGS. 13A and 13B show a rendering of a displacement having a drag panel with a parabolic shape. As described above, the control mechanisms 1120 a-1120 c may be configured to wind up and/or release the control cables 1128 a-1128 c to adjust the distance and orientation of the displacement vessel 1102 from the anchor cable 1103 and orient the drag panel 1121 with respect to the flow of water in a method similar to that described above with respect to the embodiment of the displacement vessel 1002 with arms 1138 a-1138 c. Alternatively, the locking mechanism may be coupled to the drive cable 110 to limit or inhibit the translation of the drive cable 110 and lock the displacement vessel 102 at a desired distance above the seabed.

The clamp may provide a clamping force on the drive cable 110 such that translation of the drive cable 110 is stopped or provide a force such that the translation is slowed. Where the displacement vessel has multiple control cables, a first control mechanism may wind (or release) a first control cable while a second control mechanism releases (or winds) a second control cable, again allowing the displacement vessel to change its orientation relative to the anchor cable. The ebb and flow of the water due to tidal action causes a body in the bay/ocean to drift laterally and change its position with respect to a fixed location on the seabed. The change in displaced volume ΔV of the displacement vessel is calculated by taking the water plane area Awp of the displacement vessel multiplied by the change in depth of the water h, shown in Eqn. The ballast tanks may be filled with water when the displacement vessel needs to increase its depth.

7a shows an equation for the maximum energy Emax produced by a displacement vessel if it is released when the tide is at its highest point. The displacement vessel is a structure that is capable of floating at a distance above or away from a stationary location, e.g., a bay/ocean floor or a fixed barge or platform elevated from the bay/ocean floor (described in more detail below), or on shore, or on a crane, such that the displacement vessel changes its distance to the stationary location as the tide rises and falls or is capable of being dragged laterally by the ebb and flow of water during tidal action (or both). The first displacement vessel 2102 a travels downstream with the flow of water and generates electricity by rotating a drum that is coupled to an electric generator in the directional converter 2109 as described above. The directional converter(s) may comprise any of the directional converters described herein.

The electrical power generators 1516 a-1516 c may comprise one or more of any of the generators described herein, such as for example, a 15 kW fixed magnet generator and/or a 100 kW fixed magnet generator. In an alternative embodiment of the present invention, the displacement vessels described above may be replaced with other suitable mechanisms for capturing the ebb and flow of water due to tidal action or other current flows while the generator is located at the stationary location, such as land.

The coupling mechanism 1111 may include, for example, a metal ring, latch, clip, cable loop, or any other suitable coupling device for connecting the control cables 1128 a-1128 c to the anchor cable 1103. The anchor cable 1103 is further coupled to a directional converter, as described above with respect to FIGS. Dolor muscular entrepierna . FIG. 20A shows an isometric view of an exemplary displacement vessel 2002 with a drag panel 2021 and may be similar to the displacement vessels of FIGS. FIG. 6A shows a directional converter comprising a drag energy converter. In this embodiment, anchor cable 503 has a first end at latch 507 and a second end connected to directional converter 509, defining a length therebetween. This dual-direction power generation approach may allow for twice the electrical generation capacity compared to other single direction power generation embodiments. In this way, the pulley arrangement 926 allows for electrical power to be generated using both the ebb and flow of water due to tidal action or other currents.

Generally, the tidal energy conversion assembly 500 may be substantially similar to the tidal energy conversion assemblies of any one of FIG. The directional converter 1709 works substantially similarly to the directional converters in the above-described embodiments, and may be disposed on land 1706 at any suitable distance away from the water. The floatation devices 1260 a and 1260 b are configured to float at or near the surface of the water such that the drag panel 1221 is disposed at a specified distance below the surface of the water. FIG. 12A shows a back view of a displacement vessel 1202. The displacement vessel 1202 includes a drag panel 1221 supported by floatation devices 1260 a and 1260 b. Arm 1238 b similarly houses a second control cable that may be stored within the displacement vessel 1202, such within the floatation device 1260 b, for example.

The directional converter may comprise a drive cable connected to at least one anchor cable and a drive gear that couples the drive cable and the generator. If fixed at the surface of the water 1518, the barge 1501 may comprise pylons that are driven into the bottom of the body of water (e.g., ocean, bay, or sea) and coupled to the barge 1501 itself to prevent motion, such as motion due to waves at the surface of the water.

The rack 117 a and pinion 117 b mechanism is coupled to the drive cable 110 and the drive gear 112 or, alternatively, a gear of the gearing mechanism 114. As the tide rises, via the attachment to the anchor cable, the drive cable 110 pulls on the rack 117 a and pinion 117 b mechanism, causing the rack 117 a to translate along the pinion 117 b. As the ebb and flow of tidal action causes the displacement vessels 902 a and 902 b to drift laterally toward the stationary location 906 in a first direction, the anchor cable 903 exerts a force on the first directional converter 909 a, causing the first directional converter 909 a to transmit mechanical power to a generator 916 to generate electrical power. FIG. 21B shows a tidal energy generation system configured to capture river currents.

FIG. Esclerosis multiple dolor muscular . 20A also shows an underlying structural frame of the drag panel 2021 (without a “skin” or covering). For example, the drag panel 521 may be stored within the displacement vessel in a first stored position. The directional converter 1509 may further include a reverse control mechanism 1520 to rotate the drum and wind/unwind the anchor cable, such as, for example, a motor or winch. The displacement vessel may also include a power cable extending from the displacement vessel to the stationary location to transmit electrical power to/from the displacement vessel. Such movement in the position of the displacement vessel relative to the stationary location causes the anchor cables to exert a force on the directional converter and transmit that force to a generator for producing electrical energy. The directional converter may be housed on the displacement vessel or located away from the displacement vessel. 6A. Displacement vessel frame 602 may include a buoyancy mechanism such that it may be configured, as is known in the art, to float at the surface of the water and hold the directional converter 609 shown in FIG.

In another embodiment, the displacement vessel may include redundant cables connected to redundant control mechanisms to ensure operability in the event that a cable breaks or a control mechanism malfunctions. The displacement vessel may be connected to a stationary location, such as land or a spud barge, for example, by control cables coupled to an anchor cable. In yet another embodiment, the displacement vessel may be attached to the distal end of the submerged first anchor cable 903 and the distal end of a submerged second anchor cable, where the submerged first anchor cable 903 extends in one direction away from the displacement vessel and the submerged second anchor cable extends in the opposite direction away from the displacement vessel. 1A, the anchors may include a pulley through which the anchor cables are threaded to help minimize friction.

The gearing mechanism 114 may include a gear multiplication arrangement, such as a gear multiplication box, that converts a slower rotational input into a faster rotational output. The displacement vessel 702 or floatation device 760 may include a processing or logic module configured to transmit information about the tidal energy conversion assembly to an operator. One of skill will recognize that the number of generators engaged or the rate at which the engaged generators will rotate may vary as the speed of the currents and/or the rise and fall of the tide vary throughout the tidal cycle. Similar to the tidal energy generation assembly of FIG. When the displacement vessel is perpendicular to the flow of water, it experiences a maximum amount of drag force. In particular, the rotatable drag panels 2321 a-2321 c may be coupled to and freely rotatable about respective vertical axes of the displacement vessel 2302 via axles 2315 a-2315 c.
