A method for a multilateral communication service includes acquiring at least one of a first video taken in a device of a first user, a first voice recorded in the device of the first user, and a first text message entered in the device of the first user; and specifying a plurality of display areas respectively assigned to a plurality of users participating in a conversation, and dynamically providing at least one of the first video, the first voice, and the first text message to a first display area assigned to the first user. When the first video or text message is dynamically provided, the first video or text message is dynamically displayed in the first display area, and when the first text message is dynamically displayed in the first display area, only a text message most recently entered by the first user is displayed in the first display area.

Disclosed herein is an apparatus and method for measuring bio-impedance attributable to joint movement. The bio-impedance measuring apparatus includes a constant current source, current stimulus electrodes, at least two voltage detection electrodes, a demodulator, a signal gain and offset controller and an isolated amplifier. The method of measuring bio-impedance attributable to joint movement, comprising the steps: generating a weak current by use of a constant current source; causing the weak current to flow from a point to another point; forming L voltage detecting electrode pairs from voltage detecting electodes positioned at m points on each of n-lines that divide an interval between a first joint and a second joint, between which the weak current flows, into equal n parts (m and n are natural numbers), using combination (mC2=L); detecting bio-impedance at certain periods from J (L-K) voltage detecting electrode pairs that are obtained by subtracting K voltage detecting electrode pairs, each of which exists on a single dividing line, from the formed L voltage detecting electrode pairs; and selecting a pair of voltage detecting electrodes having a highest variation of bio-impedance.

Apparatus and method for analyzing motions using bio-impedance

A semiconductor device with an error detecting and displaying circuit included in the device for detecting whether or not a semiconductor unit within the device has a predetermined output according to a given input value, and for displaying the outputted results indicating an error state of the device. The error detecting and displaying circuit for a semiconductor unit having an input circuit, a logic processing circuit and an output circuit comprises an additional logic processing circuit connected to the semiconductor unit for logically operating logic signals sent from said semiconductor device. A comparison circuit is also connected both to the additional logic processing circuit and to the output circuit of said semiconductor unit for comparing signals from the additional logic processing circuit with signals from the output circuit to thereby output the compared results. A driver is connected to the comparison circuit for producing an enabling signal depending upon the compared results applied from the comparison circuit. A display is connected to the driver for indicating whether an error occurred in the semiconductor unit, depending upon the enabling signal sent from the driver.
