Patent ID: 7673907

Claim:
A musical ice skate comprising: a boot for wearing by a user; a skate with a blade for gliding on ice; wherein the skate is mounted to the boot; an electronic module which comprises: a sensor assembly comprising a differential air pressure sensor for detecting forward and backward gliding velocity of the musical ice skate, and a left infrared distance measuring sensor and a right infrared distance measuring sensor, wherein the left infrared sensor and the right infrared sensor are mounted to face the ice, wherein the left infrared sensor and the right infrared sensor detect an amount of inside tilt from about 0° when the blade is perpendicular to the ice to about 45° the maximum lean before the side of the boot touches the ice and detect an amount of outside tilt from about 0° to about 45°, wherein the sensor assembly receives input signals from the air pressure sensor and the left infrared sensor and the right infrared sensor and outputs an output signal corresponding to a skate state; and a logic circuit converting the output signal corresponding to the skate state into a musical note output which has a pitch, a volume, and a duration, wherein the volume of the musical note output is proportional to the amount of inside tilt, or proportional to the amount of outside tilt, such that the volume increases, the closer the left infrared sensor or the right infrared sensor is to the ice; further comprising a first state, a second state, a third state, and a fourth state, wherein the first state is mapped to a first musical note, wherein the second state is mapped to a second musical note, wherein the third state is mapped to a third musical note, and wherein the fourth state is mapped to a fourth musical note, wherein a user can play a song by skating in a particular pattern, wherein there is no output when the pressure sensor assembly does not sense air flow, whereby the skate becomes a musical instrument.
