Abstract:
Disclosed are an apparatus and a method for charging power using a resonant coupling. The apparatus includes a transmission power converter for converting Direct Current (DC) power to Alternating Current (AC) power, a controller for adjusting a Q factor of a transmission resonator by using a frequency of the converted AC power and a resonant frequency of the transmission resonator and controlling adaptive impedance matching, and a transmission resonator for wirelessly transmitting the converted AC power to a receiver through the adjusted Q factor and the controlled adaptive impedance matching, the transmission resonator having a coil installed in the transmitter.
Abstract:
An apparatus and method are provided for controlling haptic feedback of an input tool for a mobile terminal. The method includes detecting, by the mobile terminal, a hovering of the input tool over an object displayed on a touch screen display of the mobile terminal; identifying a property of the object; and transmitting, to the input tool, a control signal for haptic feedback corresponding to the property of the object.
Abstract:
An electronic device is provided. The electronic device includes a main body including a battery pack and a battery cover; a non-contact near field communication antenna included in the battery pack; and a wireless charging coil portion included in the battery cover and disposed around an outer periphery of the antenna, such that the wireless coil portion does not overlap with the non-contact near field communication antenna.
Abstract:
Methods and a mobile terminal for providing visual and haptic feedback are provided. At least one first touch made to an object displayed on a touch screen is detected. The object is transformed and displayed in response to movement of the first touch. At least one second touch made to the displayed object is detected. Visual feedback is displayed on the touch screen in response to the second touch, and haptic feedback corresponding to a predetermined haptic pattern is output using a vibration motor.
Abstract:
A portable terminal and a method for providing a haptic effect to an input unit are provided. The method includes displaying at least one object on a touch screen, detecting a touch input by the input unit with respect to the object displayed on the touch screen, determining a preset mode based on the detected touch input of the input unit, and transmitting a control signal corresponding to a predetermined haptic pattern based on the preset mode to the input unit.
Abstract:
A portable terminal is provided, including a cover member which is detachably provided at a rear surface of a main body of a terminal, a resonant antenna for a reception unit provided inside of the cover member, a reception circuit unit provided inside of the main body, and a connection unit for connecting the resonant antenna for a reception unit with the reception circuit unit. The portable terminal efficiently receives the signal power provided from a charger by arranging the resonant antenna inside of the cover member, and minimizes the thickness of the portable terminal by providing the reception circuit unit inside of the main body of the terminal.
Abstract:
A sealing apparatus of a touch panel provided in a portable terminal including a body and the touch panel, wherein the sealing apparatus is attached and coupled to a coupling area between the body and the touch panel to seal the coupling area while the touch panel is suspended over the body by a resilient member.
Abstract:
A coordinate indicating device which inputs coordinates to a coordinate measuring device is provided. The coordinate indicating device includes a power receiver for wirelessly receiving drive power from the coordinate measuring device, a rectifier for rectifying the wirelessly received drive power into Direct Current (DC) drive power, a battery for storing the rectified drive power, an actuator for outputting at least one of preset vibration, frictional force, and electrostatic force, based on relative positions of the coordinate measuring device and the coordinate indicating device by using the rectified drive power provided from the battery, a coordinate indicator for indicating coordinates at predetermined coordinates on the coordinate measuring device, and a shielding portion for shielding the coordinate indicator.
