Abstract
Abstract The ski structure has its top surface covered, wholly or in part, by photovoltaic cells, which by the effect of solar radiation, generate current which recharges a series of storage batteries located preferably at a rearward zone with respect to the bindings. The ski structure may also be provided with an electronic speed sensing device, which may be powered by the current generated by the solar cells and/or the storage batteries which are recharged by those same cells.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
120 words
A ski with independent current generation and integrated eleotrie/electronic devices to the safety bindings and to the boots characterized in that it comprises: a) independent means of generating current, comprising a plurality of solar cells arranged on the ski surface; .b) a series of electric storage batteries powered continuously by said current generating means and periodically, if required, by an external source; c) means of conveying current to a boot provided with internal heating, as said boot is connected to the safety bindings; d) means of controlling the load transferred on the safety bindings by the skier and means of controllably opening those same bindings; e) means of detecting and memorizing the speed attained by the ski on the snow.
Claim 2
Dependent Claim
120 words
A ski with independent current generation and integrated eleotrie/electronic devices to the safety bindings and to the boots characterized in that it comprises: a) independent means of generating current, comprising a plurality of solar cells arranged on the ski surface; .b) a series of electric storage batteries powered continuously by said current generating means and periodically, if required, by an external source; c) means of conveying current to a boot provided with internal heating, as said boot is connected to the safety bindings; d) means of controlling the load transferred on the safety bindings by the skier and means of controllably opening those same bindings; e) means of detecting and memorizing the speed attained by the ski on the snow.
Claim 3
Dependent Claim
22 words
A ski according to Claim 1, characterized in that said solar cells are grouped into strips lying across the ski top face.
Claim 4
Dependent Claim
39 words
A ski according to Claims 1 and 2, characterized in that said solar cells rest on a layer of a relatively elastic material and are covered by a layer of a clear plastics resistant to shock, blows, and abrasions.
Claim 5
Dependent Claim
59 words
A ski according to Claim 1, characterized in that said solar cells are connected electrically in several discrete groups, each of said groups being connected to a single control circuit which verifies the output voltage of each group carrying then out series/parallel connections such that the resulting voltage is at all times higher than the storage battery charging voltage.
Claim 6
Dependent Claim
23 words
A ski according to Claim 1, characterized in that said storage batteries are located in a container preferably removably attached to the ski.
Claim 7
Dependent Claim
43 words
A ski according to Claim 1, characterized in that said means of conveying current to a boot provided with internal resistance heater comprise electric contacts provided preferably on the safety bindings and adapted to interconnect with other contacts provided in that same boot.
Claim 8
Dependent Claim
84 words
A ski according to Claim 1, characterized in that said means of controlling the load transferred by the skier on the bindings comprise substantially electric and/or electronic load sensors arranged both on the toe piece and heel piece of the safety bindings and in the structure itself of the boot, the signal of said sensors being processed by a circuit of comparision with set data, said circuit controlling the electric and/or electromagnetic opening of the same Bindings in case of preset values being exceeded.
Claim 9
Dependent Claim
57 words
A ski according to Claim 1, characterized in that said means of sensing and memorizing the speed attained by the ski comprise preferably a pair of Doppler effect emitter-receivers, located in the ski insole, whose output signal, a function of the frequency variation is proportional to the relative speed of the implement with respect to the snow.
Claim 10
Dependent Claim
36 words
A ski according to Claims 1 and 8 characterized in that said speed as sensed and processed by an electronic control circuit is memorized as maximum and/or average and displayed, on control on an optical display.
