Patent ID: 8269365

Claim:
An appliance for the conversion of wave energy into electrical energy, including a closed float element ( 1 ) and a bob element ( 2 ), with the bob element ( 2 ) being placed inside the float element ( 1 ) and mounted to be mobile in relation to the float element ( 1 ), with the bob element ( 2 ) being designed to be driven into relative movement in relation to the float element ( 1 ) under the action of the waves on the float element ( 1 ), comprising: locking means ( 13 , 50 - 59 ) designed to lock the movement of the bob element ( 2 ), and control means designed to control the locking means ( 13 , 50 - 59 ) so as to selectively lock or release the bob element ( 2 ) in order to amplify the movement of the bob element ( 2 ) by continuously adapting the dynamic of the appliance to the successive waves, wherein the bob element is an oscillating weight having a natural frequency of oscillation.
