Abstract: A closed-loop hydraulic apparatus 200 for converting wave energy comprises a pump 201 for pumping a fluid through the apparatus 200. The pump 201 includes a body 202 defining a chamber 203, and a piston 207 that partitions the chamber 203 into a working side 208 and a blind side 209. A buoyant actuator is connected to the piston 207. An inlet 64 is connected to the working side 208 of the chamber 203 so that the fluid is able to flow from the inlet 64 and into the working side 208 of the chamber 203. An outlet 63 is connected to the working side 208 of the chamber 203 so that the fluid is able to flow from the working side 208 of the chamber 203 to the outlet 63. A hydraulic controller 102 is operable to control the pump 201 by controlling the pressure of the fluid at the inlet 64 and the outlet 63 so as to optimise the output of the pump 201 in response to tidal variations and/or sea state. The pressure of the fluid at the inlet 64 and the outlet 63 is controlled in accordance with a control algorithm.

Abstract: An apparatus is provided for harnessing ocean wave energy, wherein the apparatus relieves excessive loadings on components to avoid damage thereof in adverse wave conditions. The apparatus includes a buoyant actuator and a pump anchored within the body of water. Fluid at high pressure is pumped ashore by the pump, energy is extracted as useful work at an on-shore plant, and the resultant reduced pressure fluid is returned to the offshore pump to be re-energized. The buoyant actuator is operably connected to the pump by tether and is buoyantly suspended within the body of water above the pump. The buoyant actuator is provided with a connector that includes a damping mechanism configured to maintain a substantially rigid connection between the hollow body and the tether until such time as loading therebetween exceeds a prescribed load whereupon the damping mechanism facilitates limited relative movement therebetween to relieve the loading.

Abstract: Novel games, aka, “Wordsmith Wars™”, playable by one or more participants are disclosed comprising individual game modules that have assigned value accruing to the module-winning player(s), as a unique “game platform.” Modules are selected preferably by a chance or random indicator mechanism, such as a chance wheel, cards, dice, spinning globe with indicia, balls that roll into indented platforms out of cages, tubes or boards with indicia, as in Bingo game apparatuses, et al. These modules are collectively arranged or sequenced into game segments before or during the game play with a predetermined content and duration. The modules are thusly unified into a unique, composite, single “Wordsmith Wars™” game, which further may have a common theme(s) associated within the game content modules. As well, letter(s) or word(s), and/or their correct word or phrase positions, in addition to points or money won, may also be won throughout play.

Abstract: A control circuit initiates a relationship-establishment mode of operation and operates in both a learn mode of operation and a pairing mode of operation. When the control circuit completes one of these modes of operation (for example, the learn mode of operation, the pairing mode of operation, or either) the relationship-establishment mode of operation can switch to only using the remaining mode of operation during a remainder of the relationship-establishment mode of operation. One can also disable a previously-established relationship for each of a first category of remote platforms (such as remote platforms that became authorized through a learn mode of operation) when the user presses a button. Upon then detecting a second end-user assertion of the end-user interface, the control circuit can further disable a previously-established relationship with each of a second category of remote platforms (such as remote platforms that became authorized through a pairing mode of operation).

Abstract: The present invention relates generally to constructs and in particular genetic constructs comprising polynucleotide sequences capable of release in covalently closed, circular form from a larger nucleotide sequence such as, but not limited to, a genome of a eukaryotic cell. Preferably, once released, a polynucleotide sequence is reconstituted in a form which permits expression of the polynucleotide sequence. In one embodiment, the reconstituted polynucleotide sequence comprises a coding sequence with all or part of an extraneous nucleotide such as, but not limited to, an intronic sequence or other splice signal inserted therein. Expression and in particular transcription of the coding sequence involves splicing out the extraneous sequence. The release and circularization is generally in response to a stimulus such as a protein-mediated stimulus. More particularly, the protein is a viral or prokaryotic or eukaryotic derived protein or developmentally and/or tissue specific regulated protein.
