Claim 10:
11. A wearable ergonomics improvement system comprising:
an encoder system to couple to a limb of a body, the encoder system to generate first outputs in response to movement of the limb relative to the body to determine a position of the limb relative to the body, the encoder system including:
a first encoder assembly to generate first ones of the first outputs in response to movement of a shoulder to determine a first position of the shoulder relative to the body, the first encoder assembly including:
a first rotational encoder assembly having a first rotational encoder to couple adjacent a first portion of a shoulder joint of the body, the first rotational encoder to generate first ones of the first outputs in response to movement of the shoulder;
a second rotational encoder to couple adjacent a second portion of the shoulder joint of the body different from the first portion, the second rotational encoder to generate second ones of the first outputs in response to movement of the shoulder;

a second encoder assembly to generate second ones of the first outputs in response to movement of an elbow to detect a second position of the elbow relative to the body, the second encoder assembly including:
a third rotational encoder to couple adjacent an elbow joint of the body, the third rotational encoder to generate third ones of the first outputs in response to movement of the elbow joint;

a third encoder assembly to generate third ones of the first outputs in response to movement of a hand to detect a position of the hand relative to the body, the third encoder assembly including:
a fourth rotational encoder to couple adjacent a wrist joint of the body, the fourth rotational encoder to generate fourth ones of the first outputs in response to movement of the wrist joint;

a fourth encoder assembly to couple adjacent a forearm of the body, the fourth encoder assembly to generate fourth ones of the first outputs in response to movement of the forearm to detect at least one of a position or rotation of the forearm; and
a fifth encoder assembly to couple adjacent to an upper arm portion of the body between the elbow and the shoulder, the fifth encoder assembly to generate fifth ones of the first outputs in response to movement of the upper arm to detect at least one of a position or rotation of the upper arm;

a load sensor to generate a second output representative of a load carried by the body; and
a position sensor to generate a third output representative of a position of a right foot of the body relative to a position of a left foot of the body.
