Abstract:
An apparatus for measuring skin moisture content in a user's skin is provided. The apparatus may include a signal supplier to generate an out-of-phase signal from a voltage signal obtained from the user's skin and an in-phase signal from the voltage signal, a susceptance measurement unit to measure the susceptance of the voltage signal by synchronizing the voltage signal and the out-of-phase signal received from the signal supplier, a conductance measurement unit to measure the conductance of the voltage signal by synchronizing the voltage signal and the in-phase signal, and an output unit to output sweat gland activity information of the user based on the measured conductance and skin moisture content information of the user based on the measured susceptance.
Abstract:
An objective management apparatus, medium, and method with group organization that can efficiently manage a degree of objective achievement by effectively organizing a group and giving rise to competition among group members of a group or among groups. The objective management apparatus may include a plurality of communication terminals receiving objective data including personal objectives of a plurality of users and actual result data which are results of the users' execution for achieving the personal objectives, and an objective management server connected to the plurality of communication terminals through a network and supplied with the objective data and the actual result data. Here, the objective management server may further include a group database storing a plurality of groups organized by group objectives in a database, a group designating unit designating each of the users to the group having a group objective most similar to their personal objectives, a personal objective-achievement checking unit checking whether the actual result data of each member in the group reach the group objective, and an actual result providing unit providing all the communication terminals with the actual result data of all the group members.
Abstract:
A diagnosis method and apparatus for measuring blood hemoglobin concentration, oxygen saturation, pulse rate, respiration rate, or degree of aging of blood vessels using light includes an input/output unit for receiving a command for measurement from a user and for providing information on the result of a measurement to the user; a control unit for receiving the command for measurement from the input/output unit and for generating a control signal; a light generating unit for generating at least two light beams for measurement according to the control signal; a light receiving unit for receiving the light beams transmitted through an object that is subject to measurement and for converting the received light beams into electrical signals; and a data processing unit for processing the electrical signals received from the light receiving unit and for outputting information on the result of a predetermined measurement.
