Abstract
A mechanical numeral wheel counter comprising several numeral wheels and switch sensors set alternatively around the numeral wheels. The circumferences of the numeral wheels are divided into equal spaces and a sensing material is placed on each of the spaces. As the numeral wheels rotate, the status of each sensor will be different when the numeral wheel is at different position. Signals output from the sensors are processed by a computer capable of reading and recognizing the signals. A standard digital wave form can be obtained from the processed signals received by the computer from the sensors.
Claims12
A mechanical numeral wheel counter comprising:
- one or more coaxial numeral wheels, the circumference of each coaxial numeral wheels being divided into several equal spaces, each of the spaces having a sensing material applied thereto;
- one or more switch sensors, the switch sensors being alternately set around the numeral wheels.
A method of reading switch signals output from a mechanical numeral wheel counter, the method comprising the steps of:
- dividing the circumference of the numeral wheels into several equal spaces;
- setting sensors around the circumference of each of the numeral wheels;
- placing a sensing material on the numeral wheel, the sensing material being aligned with the equal spaces on the numeral wheel;
- reading a signal from the sensor, the status of each sensor being different for each different position of the numeral wheel,
- processing the signal from the sensor by a computer, the computer being able to read and recognize the signals from the said numeral wheel and creating a standard digital wave.
