| 20090023087 | HYBRID TONER AND METHOD OF PREPARING THE SAME - A hybrid toner includes micro cylinders, cores inserted into the micro cylinders, and an external addition layer covering the micro cylinders to which the cores are inserted. The hybrid toner prevents a toner blocking phenomenon, image contamination, and low storage stability which occur due to dispersion of wax and colorants to an outer surface of the toner. | 01-22-2009 |
| 20090128919 | HEAD-MOUNTED DISPLAY - A head-mounted display for forming a virtual image at a predetermined distance in front of a user includes: a left eye unit and a right eye unit, each eye unit having an image module for generating an image and an optical system disposed at a predetermined distance from the image module and towards the user's eyeball for forming a virtual image at a predetermined distance from the user by enlarging the generated image. A main body has both the left eye unit and the right eye connected thereto, wherein portions of the main body to which the left eye unit and the right eye unit are connected are each inclined to sustain a predetermined angle from the center of the main body. By utilizing a user's visual convergence so that a virtual image may be displayed at a target position, variation of a distance determination between users is reduced, and thus a viewing effect to the user of a virtual image being formed at a target position is obtained, thereby improving user satisfaction. | 05-21-2009 |
| 20090155701 | TONER AND PROCESS OF PREPARING THE SAME - A toner includes a core containing a binder resin, wax, and a colorant, and an external additive layer coating the core, wherein the core is prepared such that it is extruded and extended to have a fiber phase, and is pulverized. The toner has an improved fixing ability to allow an electrostatic image to be fixed at a low temperature while having an excellent durability and an improved storage stability, while exhibiting reduced toner blocking and offset phenomena. | 06-18-2009 |
| 20100096936 | VIBRATION MOTOR - A vibration motor includes a first resilient member and a second resilient member providing resilient forces in opposite directions; a first vibrator and a second vibrator coupled to the first resilient member and the second resilient member respectively; a magnetic body coupled to the first vibrator to create a magnetic field; and a coil applying a current of a predetermined frequency band in the region where the magnetic field is created. | 04-22-2010 |
| 20100127581 | VIBRATION MOTOR FOR PORTABLE TERMINAL - Disclosed is a vibration motor for a portable terminal, including a flat spring; a cylindrical magnetic substance mounted on the flat spring; an annular magnetic substance disposed around the cylindrical magnetic substance mounted on the flat spring; and a coil disposed between the cylindrical magnetic substance and the annular magnetic substance, wherein the magnetic substances perform a linear reciprocal movement by the electromagnetic force generated between the magnetic substances and the coil and by the elastic force of the flat spring as an electric current is applied to the coil. The vibration motor operates at higher resonant frequencies than those of conventional vibration motors, thereby improving the sense of an after-vibration and realizing a delicate haptic feedback function. | 05-27-2010 |
| 20100141606 | METHOD FOR PROVIDING HAPTIC FEEDBACK IN A TOUCH SCREEN - Disclosed is a method for providing a haptic feedback in a touch screen, which includes displaying a plurality of soft buttons on a touch screen; applying a first pattern vibration to the touch screen if a pressing detection value for a corresponding soft button according to contact of a user input means reaches a predetermined first threshold value; and applying a second pattern vibration to the touch screen if a pressing detection value for the corresponding soft button reaches a predetermined second threshold value, the second pattern vibration being different from the first pattern vibration, the second threshold value being different from the first threshold value. | 06-10-2010 |
| 20100148944 | HAPTIC FUNCTION CONTROL METHOD FOR PORTABLE TERMINALS - A haptic function control method for a portable terminal including a receipt-specific vibration motor that vibrates in a first frequency band and a haptic-specific vibration motor that vibrates in a second frequency band. At least one of the receipt-specific vibration motor and the haptic-specific vibration motor is driven based on a drive sampling frequency signal. The drive sampling frequency signal that vibrates the receipt-specific vibration motor and the haptic-specific vibration motor is determined from the first frequency band and the second frequency band. | 06-17-2010 |
| 20100148945 | HAPTIC FEEDBACK DEVICE FOR A PORTABLE TERMINAL - A haptic feedback device for a portable terminal. The haptic feedback device includes an input member, a vibration member that passes through the input member, and serves as a rotation axis of the input member, and a piezo actuator in contact with the vibration member. As the input member rotates or pivots with respect to the rotation axis, the piezo actuator actuates to vibrate the vibration member. | 06-17-2010 |
| 20110006888 | METHOD AND APPARATUS FOR GENERATING VIBRATIONS IN PORTABLE TERMINALS - A method and apparatus for generating vibration in a portable terminal are provided. The apparatus for generating vibration in a portable terminal includes a plurality of vibrators mounted and driven to generate vibration in a single vibration direction at positions separated from each other by predetermined distances on the portable terminal, and a controller for determining respective vibration patterns of the plurality of vibrators according to a control operation of the portable terminal and driving the plurality of vibrators according to the vibration patterns. | 01-13-2011 |
