Abstract: According to one embodiment, a data input system includes an active stylus and an apparatus. The active stylus switches a mode from a first mode in which the signal is output with a first transmission interval to a second mode in which the signal is output with a second transmission interval longer than the first transmission interval when a pressure in a handwriting input operation is not detected for more than a first period. The apparatus displays an object indicative of a position pointed to by the active stylus based on the signal. The apparatus maintains, when the active stylus is in the second mode, a display state of the object displayed on the basis of the signal output at a first timing until the signal is output at a second timing following the first timing.

Abstract: According to one embodiment, an active stylus pen includes a first signal generator, a second signal generator and a transmitter. The first signal generator generates a first signal capable of notifying an electronic device capable of accepting an operation executed by the active stylus pen that the pen tip is in contact with the electronic device when an operation of bringing the pen tip into contact with the electronic device is executed. The second signal generator generates a second signal capable of notifying the electronic device that the eraser is in contact with the electronic device when an operation of bringing the eraser into contact with the electronic device is executed.

Abstract: According to one embodiment, an active stylus pen includes a power supply circuit, an operation detector, a counter and a grip detector. The power supply circuit supplies power from a battery to components in the active stylus pen. The operation detector detects an operation with the active stylus pen being performed for an electronic device capable of receiving the operation. The counter counts an elapsed time after detecting the operation being performed. The grip detector detects the active stylus pen being gripped. The power supply circuit reduces power supply to the components when the elapsed time exceeds a value defined in advance and the active stylus pen being gripped is not detected.

Abstract: According to one embodiment, a capacitance type touch panel device which is provided on a screen of a display device and is allowed to detect a touch of a stylus is provided. The touch panel device includes a loop antenna, a sensor and a controller. The sensor is connected to the loop antenna and is configured to detect noise which generates in accordance with driving of the display device. The controller is configured to detect the touch at timing different from timing in which the noise generates in the cycle of generation of detected noise.

Abstract: According to one embodiment, an electronic device is provided with a first detection module, a second detection module and a rendering module. The first detection module detects the region of a detection surface that contacts an indicator. The second module detects, using a method different from a method of the first detection module, a pressure corresponding to a load that occurs when the indicator contacts the detection surface. The rendering module renders the shape of the region, detected by the first detection module, on the screen of a display with a concentration corresponding to the pressure detected by the second detection module.

Abstract: According to one embodiment, an electronic apparatus comprises a detector and a processor. The detector is configured to chronologically detect coordinates of positions sequentially indicated by an indicator on a detection surface. The processor is configured to determine a level of noise based on the coordinates, and to correct the coordinates using a correction strength value corresponding to the level of noise.

Abstract: According at least to one embodiment, a digitizer pen includes a resonant circuit, a first switcher, a measurement processor, and a transmission module. The resonant circuit includes a coil. The first switcher allows a core tip of a core of a plurality of cores to be exposed. The measurement processor measures pressure applied to the exposed core. The transmission module transmits the pressure applied to the exposed core to the measurement module.

Abstract: An information apparatus according to an embodiment includes a first input device for carrying out a pen input, a second input device for carrying out a touch panel input, and a correction processor for correcting a first coordinate detected by the first input device based on a second coordinate detected by the second input device.

Abstract: One embodiment provides a stylus pen configured to be used as an input pen in a tablet input device. The stylus pen includes a pen tip including a high friction material, and a portion of the pen tip includes an approximately spherical shape. The stylus pen further includes a touch point and a touch point clarifying structure. The touch point clarifying structure is configured to enhance a visibility of the touch point of the stylus pen to a touching object.

Abstract: According to one embodiment, a power transfer system includes a power transmission apparatus and a power reception apparatus. The power transmission apparatus has a power transmission module, and a first wireless communication device configured to transmit physical profile information of the power transmission apparatus. The power reception apparatus has a power reception module, a second wireless communication device configured to receive the physical profile information, and a controller. Wireless power transfer is conducted between the power transmission module and the power reception module. The controller is configured to cross-check a physical profile of a power signal of the wireless power transfer received by the power reception module with the physical profile information and identify the first wireless communication device based on a result of the cross-check.
