Provided is a position detector including a coil configured to function as a sensor and including a transfer coil that transfers an alternating magnetic field based on a transfer signal to a position indicator, and a signal processing circuit connected to the coil and configured to detect a pen signal generated by the position indicator, generate the transfer signal with a frequency based on frequency information of the detected pen signal, and transfer the transfer signal to the transfer coil.

Position detector, integrated circuit, and position detection method

An information input device includes: a communication interface configured to communicate with each of a first external apparatus that operates using a first operating system and a second external apparatus that operates using a second operating system; and a controller configured to operate in a first mode corresponding to a first driver used by the first external apparatus when transferring data to the first external apparatus, and operate in a second mode corresponding to a second driver different from the first driver and used by the second external apparatus when transferring data to the second external apparatus.

Information input device, method, and computer-readable medium for operating a controller in different modes corresponding to different device drivers

A method performed by a pen or a pen detection apparatus that detects the pen, the method includes: acquiring a pen pressure level according to a force applied to a pen nib of the pen; generating a pen-down event or a pen-up event based on a result of comparing the pen pressure level and a pen pressure determination threshold; acquiring a proximity value indicating a positional relationship between the pen and the pen detection apparatus from a proximity detector provided on one of the pen and the pen detection apparatus; and updating the pen pressure determination threshold based on the pen pressure level when the proximity value indicates that the positional relationship between the pen and the pen detection apparatus satisfies a predetermined relationship.
