Class / Patent application numberDescriptionNumber of patent applications / Date published
178180010 Position coordinate determination for writing (e.g., writing digitizer pad, stylus, or circuitry) 372
178043000 Space induction 2
20090057039ELECTRONIC CIRCUIT - The invention provides an electronic circuit capable of simplifying a transmitter circuit and yet realizing low-voltage drive and low power consumption where communications between substrates are realized by inductive coupling. As the transmission data Txdata are turned from LOW to HIGH, the transistor T03-05-2009
20090133942POWER TRANSMISSION CONTROL DEVICE, POWER TRANSMITTING DEVICE, ELECTRONIC INSTRUMENT, AND NON-CONTACT POWER TRANSMISSION SYSTEM - A power transmission control device provided in a power transmitting device of a non-contact power transmission system includes a driver control circuit that controls a power transmitting driver that drives a primary coil, a load state detection circuit that detects a power-receiving-side load state, and a control circuit that controls the power transmission control device. The control circuit acquires a reference value used to determine a power-receiving-side load state after starting normal power transmission in a reference value acquisition period, the reference value acquisition period being a period after receiving ID authentication information from the power receiving device, but before starting the normal power transmission.05-28-2009
178063000 Cable or capacity 1
20080217076Method and Device for Bidirectional Single-Wire Data Transmission - A device and a method for bidirectional single-wire data transmission of data information between an electronic control unit and at least one peripheral unit. A predefined constant voltage and/or a predefined constant current is applied to a driver device of the electronic control unit to produce voltage-coded and/or current-coded information. The voltage-coded and/or current-coded information is transmitted from the driver device of the electronic control unit to a driver device 09-11-2008

20130206487METHOD AND DEVICE FOR DETERMINING THE TRAIN LENGTH OF A PLURALITY OF COUPLED RAILWAY TRACTION VEHICLES - A method and a device for determining a train length of a plurality of coupled railroad traction vehicles, each having a vehicle device with an ID specific to the railroad traction vehicle, include determining the train length of arbitrarily long train sets in a secure and simple signaling manner by having vehicle devices determine if the railroad traction vehicle is coupled on one side or both sides by evaluating coupling contacts. The IDs of all of the coupled railroad traction vehicles or ID pairs indicating adjoining relationships of railroad traction vehicles directly coupled to one another are successively transmitted to a particular vehicle device by digital I/O connections between the vehicle devices. The device determines the train length as a function of received IDs or ID pairs.08-15-2013
178064000 Coil transformer 1
20120292119ON-BOARD TRANSPONDER DEVICE AND METHOD OF VERIFYING SOUNDNESS THEREOF - The present invention includes a telegraph controller and an FSK modulator that serve as a signal transmission unit that creates a checking telegraph that is different from a controlling telegraph and transmits the checking telegraph to a pickup coil, an FSK demodulator and a telegraph controller that serve as a signal reception unit that restores telegraph information from the checking telegraph received via the pickup coil, and a communication controller that compares transmission telegraph information included in a checking telegraph transmitted from the signal transmission unit with reception telegraph information restored from a received checking telegraph that includes the transmission telegraph information to verify a telegraph reception function on an on-board side.11-22-2012
178002000 Code changers 1
20100263946INFORMATION PROCESSING APPARATUS, INCLINATION DETECTION METHOD AND INCLINATION DETECTION PROGRAM - Devices, methods, and non-transitory computer-readable media consistent with the invention may be used to detect an area of contact on a surface of the device by an external object. Then, an inclination of the device may be determined based on the detected area of contact.10-21-2010
20090014218METHOD FOR DATA TRANSMISSION IN A SERIAL COMMUNICATION PROTOCOL BY MEANS OF TELEGRAMS AND DATA TRANSMISSION DEVICE USING THIS METHOD - A method for data transmission in telegrams in a serial communication protocol comprises the following steps: 01-15-2009
