The modular robot system has N cube-shaped unit robots (where N is an integer greater than 2), each cube-shaped unit robot including: a cube-shaped housing; a step motor located inside the housing; and a controller located inside the housing to control the step motor, wherein the housing has a mounting groove formed on one surface thereof to mount a rotary body rotating by a rotary shaft of the step motor thereon and connection grooves with the same shape as each other formed on the five surfaces thereof, so that through connectors mounted on the connection grooves, one cube-shaped unit robot is connectable to another cube-shaped unit robot.

Abstract: A modular robot system can be formed by assembling a plurality of cube type unit robots. The modular robot system includes N cube type unit robots, wherein: one of the N cube type unit robots serves as a central control terminal, the cube type unit robot serving as the central control terminal assigns a distinguishable ID number to each of the N cube type unit robots; each robot including a cube-shaped housing, a step motor and a control unit installed inside the housing; the housing has one surface including a mounting groove to allow a rotational body rotating by a rotation shaft of the step motor to be mounted therein, and the other surface including a connection groove in the same shape as the mounting groove; and different cube type unit robots can be connected to each other by means of a connection body mounted in the connection groove.

Abstract: A method for forming a group from a plurality of Bluetooth devices includes forming one subgroup with some of the plurality of Bluetooth devices; and, with respect to Bluetooth mediating devices that are at least some of the plurality of Bluetooth devices belonging to the subgroup, forming, by the Bluetooth mediating device, one lower subgroup having the subgroup as an upper subgroup thereof, together with the plurality of Bluetooth devices which do not yet belong to any subgroup.

Abstract: Disclosed are a device and a method for displaying a private image on a public display device. Image sequence pattern is generated for the private image and the corresponding masking image. The masking image is made from the dynamic inverse image of the private image, based on the refresh rate of the display device and the image sequence pattern. The masking image can screen the private image more effectively. The private image and the masking image is displayed on the display device according to the image sequence pattern.

Abstract: The present invention discloses a keypad matrix element shift arrangement method having an efficient an neighboring numeral traffic line customarily. According to the present invention, an information input apparatus whose key arrangement varies includes a key display section of a square shape for displaying a key image, and a key input section for receiving information of a corresponding key at a predetermined location of the key image displayed by the key display section. The information input apparatus further an input controller for generating an image of predetermined key arrangement selected among a plurality of key images in which numeric keys are shift-arranged so that there is no crossing in an neighboring numeral traffic line, providing the generated image to the key display section, and converting information inputted through the key input section into an actual key value according to the predetermined key arrangement.

Abstract: A method of transmitting a shutter opening/closing signal in a private image display device. In the method of the present invention, a shutter opening/closing sequence time point generated by a shutter opening/closing sequence time point generated by a shutter opening/closing sequence and signal generating unit is synchronized with a time point of the timer. The shutter opening/closing signal is transmitted to the transmission unit prior to the shutter opening/closing sequence time point by a predetermined period. The shutter opening/closing signal is transmitted from the transmission unit to the reception unit at a predetermined time point of the time. According to the present invention, there is an advantage in that a user visual perception performance can be improved by overcoming a transmission delay occurring when the shutter opening/closing signal is transmitted from the private image display device to the shutter device.
