what do they call flip flops in australia?
thongs
they are made from a wide variety of materials, as were the ancient thong sandals. the modern sandals are made of more modern materials, such as rubber, foam, plastic, leather, suede, and even fabric. thongs made of polyurethane have caused some environmental concerns; because polyurethane is a number 7 resin, they can't be easily discarded, and they persist in landfills for a very long time. in response to these concerns, some companies have begun selling flip-flops made from recycled rubber, such as that from used bicycle tires, or even hemp, and some offer a recycling program for used flip flops.

a ring counter with 15 sequentially ordered states is an example of a state machine. a 'one-hot' implementation would have 15 flip flops chained in series with the q output of each flip flop connected to the d input of the next and the d input of the first flip flop connected to the q output of the 15th flip flop. the first flip flop in the chain represents the first state, the second represents the second state, and so on to the 15th flip flop which represents the last state. upon reset of the state machine all of the flip flops are reset to '0' except the first in the chain which is set to '1'. the next clock edge arriving at the flip flops advances the one 'hot' bit to the second flip flop. the 'hot' bit advances in this way until the 15th state, after which the state machine returns to the first state.
