4 . The article of sports equipment of claim 3 being a skate, wherein the component includes a runner of the skate.
5 . The article of sports equipment of claim 4 , wherein the first mode includes a first profile of the runner, and the second mode includes a second profile of the runner.
6 . The article of sports equipment of claim 5 , wherein the first profile is more curved than the second profile.
7 . The article of sports equipment of claim 5 , wherein the first profile is more parabolic than the second profile.
8 . The article of sports equipment of claim 5 , wherein the component further includes an actuator caused to deform the runner to switch from the first mode to the second mode.
9 . The article of sports equipment of claim 3 being a ski, wherein the component includes a base of the ski.
10 . The article of sports equipment of claim 9 , wherein the first mode includes a first profile of the base, and the second mode includes a second profile of the base.
11 . The article of sports equipment of claim 10 , wherein the second profile is more parabolic than the first profile.
12 . The article of sports equipment of claim 3 being a ski boot, wherein in the first mode a binding of the ski boot is shifted to a first angle, and in the second mode the binding of the ski boot is shifted to a second angle different from the first angle.
13 . The article of sports equipment of claim 2 , wherein the sensor includes at least one force sensor; wherein the processing entity is configured to process the electronic signal to determine that the change in movement is a changed in a forward skating movement pattern; and wherein the component is caused to switch from the first mode to the second mode in response to the change in forward skating movement pattern.
14 . The article of sports equipment of claim 13 , wherein the first mode has a more aggressive runner pitch than the second mode.
15 . The article of sports equipment of claim 2 , wherein the sensor includes at least one force sensor; wherein the processing entity is configured to process the electronic signal to determine that the movement of article sports equipment is changed from a rest situation to a dynamic situation; and wherein the component is caused to switch from the first mode to the second mode.
16 . The article of sports equipment of claim 15 being a skate, wherein the component includes a suspension portion of the skate.
17 . The article of sports equipment of claim 16 , wherein the first mode includes a first stiffness of the suspension portion of the skate, and the second mode includes a second stiffness of the suspension portion of the skate, the first stiffness being different from the second stiffness.
18 . The article of sports equipment of claim 2 , wherein the sensor includes at least one accelerometer; wherein the processing entity configured to process the electronic signal to determine that the change in movement is a change from a high-speed situation to a low-speed situation; and wherein the component is caused to switch from the first mode to the second mode in response to the change from a high-speed situation to a low-speed situation.
19 . The article of sports equipment of claim 18 being a skate, wherein the component includes a tongue of the skate, wherein in the first mode the tongue has a first stiffness, and wherein in the second mode the tongue has a second stiffness different from the first stiffness.
20 . The article of sports equipment of claim 18 being a skate, wherein the component includes a blade of the skate, wherein in the first mode the blade has a first pitch indicating a first angle in which the blade leans towards an ice, and wherein in the second mode the blade has a second pitch indicating a second angle in which the blade leans towards the ice, the second angle being different from the first angle.
21 . The article of sports equipment of claim 2 , wherein the sensor includes at least one pressure sensor; wherein the processing entity is configured to process the electronic signal to determine that the movement of article sports equipment is changed from a slap shot movement pattern to a wrist shot movement pattern; and wherein the component is caused to switch from the first mode to the second mode.
22 . The article of sports equipment of claim 21 being a stick, wherein the component includes a shaft of the stick.
23 . The article of sports equipment of claim 22 , wherein in the first mode the shaft has a first stiffness, and wherein in the second mode the shaft has a second stiffness different form the first stiffness.
24 . The article of sports equipment of claim 1 , wherein the component is further caused to switch among at least three modes in response to the change of the movement of the article of sports equipment, the at least three modes including the first mode and the second mode, the change of the movement corresponding to a respective one of at least three movement patterns.
