Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
106 words
A method for controlling an apparatus, said method comprising the steps of: inputting a predetermined temperature value into a microprocessor; detecting a voltage value of a power supply; determining a variation in voltage from said power supply by comparing the detected voltage from said power supply with a reference voltage value stored in said microprocessor; detecting a temperature variation; determining a fuzzy correlation by comparing a variation in room temperature stored in said microprocessor with the detected temperature variation over a predetermined time period; and displaying an operating state, which corresponds to said variation in voltage or said fuzzy correlation, of the apparatus on a display.
Claim 2
Independent Claim
106 words
A method for controlling an apparatus, said method comprising the steps of: inputting a predetermined temperature value into a microprocessor; detecting a voltage value of a power supply; determining a variation in voltage from said power supply by comparing the detected voltage from said power supply with a reference voltage value stored in said microprocessor; detecting a temperature variation; determining a fuzzy correlation by comparing a variation in room temperature stored in said microprocessor with the detected temperature variation over a predetermined time period; and displaying an operating state, which corresponds to said variation in voltage or said fuzzy correlation, of the apparatus on a display.
Claim 3
Dependent Claim
38 words
The method of claim 1, wherein said apparatus is a combustion apparatus and wherein the variation in temperature stored in said microprocessor is the variation of temperature per unit time at each controlling step of said combustion apparatus.
Claim 4
Dependent Claim
28 words
The method of claim 2, wherein said each controlling step can be divided into a plurality of steps from the lowest combustion state to the highest combustion state.
Claim 5
Dependent Claim
65 words
A control device for a combustion apparatus, said device comprising: memory means for storing reference temperature data and a reference voltage; means for measuring temperature; means for measuring a voltage supplied to said combustion apparatus; and means for controlling combustion based on the measured temperature and the reference temperature data and based on the detected voltage and a reference voltage stored in said memory means.
Claim 6
Dependent Claim
65 words
A control device for a combustion apparatus, said device comprising: memory means for storing reference temperature data and a reference voltage; means for measuring temperature; means for measuring a voltage supplied to said combustion apparatus; and means for controlling combustion based on the measured temperature and the reference temperature data and based on the detected voltage and a reference voltage stored in said memory means.
Claim 7
Dependent Claim
20 words
The control device according to claim 4 further including means for displaying the measured temperature and the reference temperature data.
Claim 8
Independent Claim
63 words
A method for controlling a combustion apparatus, said method comprising the steps of: storing reference temperature data and a reference voltage; measuring temperature; detecting a voltage corresponding to a power supplied to said combustion apparatus; and controlling combustion based on the measured temperature and the reference temperature data and based on the detected voltage and a reference voltage stored in said processing means.
Claim 9
Independent Claim
63 words
A method for controlling a combustion apparatus, said method comprising the steps of: storing reference temperature data and a reference voltage; measuring temperature; detecting a voltage corresponding to a power supplied to said combustion apparatus; and controlling combustion based on the measured temperature and the reference temperature data and based on the detected voltage and a reference voltage stored in said processing means.
