Abstract
A compound bow includes a riser, an upper limb, and a lower limb, the upper limb and lower limbs coupled to the riser. The compound bow may include a draw sensor. The compound bow includes a performance module coupled to the riser, the performance module operatively coupled to the draw sensor. A compound bow may include an arrow chronometer assembly. A method may include determining draw weight or length based on measurements of the draw sensor. A method may include determining arrow speed based on measurements of the arrow chronometer assembly.
Claims23
A compound bow comprising:
- a riser;
- an upper limb, the upper limb coupled to the riser;
- a lower limb, the lower limb coupled to the riser;
- a draw sensor, the draw sensor including a grip strain gauge positioned between a grip and the riser;
- a performance module integrally housed in the riser, the performance module operatively coupled to the draw sensor, the performance module including:
- a display;
- a sensor package including one or more of an accelerometer or gyroscope;
- a rotary encoder;
- a GPS module;
- and
- a power storage device;
- an arrow chronometer assembly, the arrow chronometer assembly integrally housed in the riser at or near an arrow rest of the riser, the arrow chronometer assembly including one or more sensors positioned to detect movement of an arrow through the arrow chronometer assembly.
