Abstract
A sensor for measuring the flex of a pole when exposed to one or more forces, the sensor including at least one magnet and Hall Effect sensor combination, wherein the at least one magnet and Hall effect sensor are at a predetermined position relative to one another when there are no forces acting on the pole and which are movable relative to one another when forces act on the pole, such that a signal proportional to the relative movement is generated by the sensor.
Claims20
A sensor for measuring the flex of an oar when exposed to one or more forces, the sensor comprising:
- a magnet and Hall Effect sensor combination, wherein the magnet and the Hall effect sensor of the combination are at a predetermined position relative to one another when there are no forces acting on the oar and which are movable relative to one another when forces act on the oar, such that a signal proportional to the relative movement is generated by the sensor;
- a cylindrical first portion locatable inside of the oar and configured to move with the oar when the oar is acted upon by forces;
- and
- a protruding second portion having an end in juxtaposition with an end surface of the cylindrical first portion.
A sensor for measuring the flex of a pole when exposed to one or more forces, the sensor comprising:
- a magnet and Hall Effect sensor combination locatable inside of the pole, wherein the magnet and the Hall effect sensor of the combination are at a predetermined position relative to one another when there are no forces acting on the pole and which are movable relative to one another when forces act on the pole, such that a signal proportional to the relative movement is generated by the sensor;
- a cylindrical first portion adapted to fit tightly within the pole and move therewith when the pole is acted upon by forces;
- and
- a protruding second portion that is not adapted to move with the pole and which has an end in juxtaposition with an end surface of the cylindrical first portion.
An oar comprising:
- a sensor for measuring the flex of the oar when exposed to one or more forces, the sensor disposed within the oar and comprising:
- a magnet and Hall Effect sensor combination, wherein the magnet and the Hall effect sensor of the combination are at a predetermined position relative to one another when there are no forces acting on the oar and which are movable relative to one another when forces act on the oar, such that a signal proportional to the relative movement is generated by the sensor;
- a cylindrical first portion including first and second circular end portions and a plurality of flexible spiral members connecting the first and second circular end portions;
- and
- a protrusion extending from the first circular end portion and having an end in juxtaposition with an internal surface of the second circular end portion.
