Electronic scale for measuring weight using two measurements and a processor therefor
First Claim
1. An electronic scale for measuring a weight comprising:
- a weight sensor arranged to measure a weight of a load on the weight sensor for producing a measurement output,wherein the weight sensor is arranged to function in three continuous measurement ranges including a first range for covering a lighter weight region with a normal sensitivity, a second range for covering a middle weight region with high sensitivity in which the output of the weight sensor more sensitively changes against the change in the load thereon than in the first range of the normal sensitivity, and a third range for covering a heavier weight region with a normal sensitivity equal to that of the first range;
a memory arranged to store a first measurement output produced by the weight sensor;
a controller arranged to calculate a difference weight between the first measurement output and a second measurement output produced by the weight sensor; and
a display arranged to display a measurement output with a first scale interval and to display the difference weight with a second scale interval finer than the first scale interval,wherein the first and second measurement outputs are produced in the second range of the high sensitivity for the display of the difference weight with the second scale interval andwherein the weight sensor is so arranged that the second range of the high sensitivity is capable of being shifted to cover both the first and second measurement outputs.

Abstract
An electronic scale functions in a normal and a high sensitivity measurement regions. The weights of mother alone and mother plus infant are measured in the high sensitivity region. The difference between the two measurements is the weight of infant alone, which is displayed with a finer scale interval than the normal one. The high sensitivity region is automatically shifted for covering the two measurements. The degree of shift is stored to correct the absolute mother weight. The infant weight is transmitted to a mobile phone, which displays growth curve of infant in comparison with a statistics growth curves provided by a server through the internet. The infant weight is uploaded to the server for incorporation into the statistics. The statistics is based on data gathered form a plurality of mobile phones, which are each authenticated to increase reliability of the statistics against false weight data upload.

10. A processor of a mobile phone for the care of weight change in cooperation with an electronic scale for measuring a weight comprising:
-
a first communicator arranged to receive weight information from the electronic scale; a second communicator arranged to receive statistics of weight information based on a number of other mobile phones unknown to a user of the mobile phone for the care of weight change from an outside database receiving the weight information of the number of mobile phones under anonymity each other; a memory arranged to store the weight information received by the first communicator and the statistics of weight information received by the second communicator; a display arranged to retrieve the weight information and the statistics of weight information from the memory for displaying them in a comparative manner; and a third communicator arranged to transmit the weight information to the outside database to participate in the statistics, wherein the transmitted weight information is incorporated into the statistics information received from the outside database so that the statistics of weight information is based on the mobile phone and the number of other mobile phones unknown to the user of the mobile phone. - View Dependent Claims (11, 12, 13, 17)

14. A processor for the care of weight change with a database in cooperation with a number of mobile phones comprising:
-
a first communicator arranged to receive weight information from the number of the mobile phones under anonymity each other; a memory arranged to store the weight information received from the number of mobile phones by the first communicator; a processing unit arranged to process the weight information in the memory so as to incorporate the weight information received from the number of mobile phones into a statistics information under anonymity; and a second communicator arranged to provide each of the mobile phones with the same statistics information, respectively, under anonymity each other. - View Dependent Claims (15, 16)
