Patents by Inventor Tung-Chuang Jan

Tung-Chuang Jan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20060074324
    Abstract: A biosensing meter plus blood pressure measuring apparatus has a slot, an inflatable and deflatable cuff, a pressure sensor and a microprocessor. The slot is able to accept a code card with multiple parameters or a sample strip that comprises a reaction well and a plurality of electrodes thereon in contact with the reaction well. The pressure sensor is used for detecting arterial counterpressure pulses and oscillations at each of the cuff pressure deflating process. The microprocessor is used for controlling the cuff, converting counterpressure pulses and oscillations to voltage signals, processing the voltage signals into a sequence of peak amplitudes and determining a systolic pressure and a diastolic pressure. Furthermore, the microprocessor is used for reading multiple parameters in the code card to measure an analyte in an analyte-containing fluid and calculating a concentration of the analyte.

  • Patent number: 6475154
    Abstract: A method and an apparatus for non-invasive blood-pressure measurement performing step-by-step inflating and deflating of the cuff pressure are disclosed. The step-by-step inflation-and-deflation process of the invention can determine the highest inflating pressure and provide enough data to obtain a curve fitting envelope. Therefore, the inflation pressure of the cuff to be pumped much higher than the normal systolic pressure of the conventional method can be prevented. A comfortable systolic and diastolic pressure determination method applying fuzzy control is achieved.

  • Patent number: 6458085
    Abstract: A method and an apparatus for oscillometric blood-pressure measurement taking heart pulses for reference to determine the systolic and diastolic pressure are disclosed. The cuff is merely inflated to a cuff pressure above the mean arterial pressure of the artery. Therefore, the inflation pressure of the cuff to be pumped much higher than the normal systolic pressure of the conventional method can be prevented. A comfortable systolic and diastolic pressure determination method applying fuzzy control is achieved.

  • Patent number: 6439768
    Abstract: A thermometer having a symmetrical probe with a sensor for sensing temperatures and a processor, a method for calculating temperature of an object by a second-order differential equation comprises the steps of obtaining temperatures from object, performing a first temperature calculation to obtain an initial prediction of temperature of object, adding a compensation coefficient, generating a compensated temperature based on a combination of initial prediction of temperature of object and compensated coefficient, and calculating a stabilized prediction of temperature of object based on compensated temperature before sensor has reached temperature of object. This thermometer can effectively decreasing error during heat transfer process.
