Abstract: A portable electronic apparatus configured to be battery-powered and to display a visual program received from the outside is provided. The portable electronic apparatus has a receiver configured to receive EPG data related to the program, a battery power estimator configured to estimate remaining battery power, an image processor configured to process an image included in the program by using a plurality of functions of image quality control, and a controller configured to set how to use each of the functions by means of the image processor. The controller is configured to estimate battery lasting time on the basis of the remaining battery power, a setting of the use of the functions and the EPG data. The controller is configured to update the setting of the use of the functions upon judging the remaining battery power to be short of enough to display the program to the end.

Abstract: Apparatus for independently guiding two overlaid fabric workpieces as they are simultaneously fed through a sewing work station and are seamed together, wherein the guide apparatus comprises a pair of opposed guide wheels located upstream from the work station with respect to the direction of workpiece feed through the work station; separate servo motors for rotating guide wheels in planes perpendicular to the direction of workpiece feed; a separating bar for spacing apart the two workpieces and for individually pressing them against a different one of the guide wheels; and separate sensors for monitoring the edges of each workpiece and for controlling the servo motors separately to rotate their guide wheels so as to center each workpiece edge opposite its corresponding sensor.
