    Abstract: PURPOSE: A control method of a motor driving system is provided to improve the performance of a motor driving system by preventing oscillatory behaviors in the motor driving system. CONSTITUTION: A test driving signal is applied to the motor of a machine system in order to generate oscillatory behaviors in the machine system. A backchannel electric signal due to the motor of the machine system is detected from the oscillatory behaviors. The resonant frequency of the machine system is calculated from the backchannel electric signal. The resonant frequency of the machine system is saved in a register(910~930). The resonant frequency of the machine system is used in a run time mode.

    Abstract: Systeme und Verfahren zum Bestimmen von Positionen für Zweifachberührungsbedienungen, die an einem resistiven Berührungsbildschirm mit vier Drähten durchgeführt werden. Die Systeme und Verfahren können das Messen von Signalen von Elektrodenpaaren an jeder von einer ersten und zweiten resistiven Folie des resistiven Berührungsbildschirms in zwei Bedienungsphasen einschließen. Die Systeme und Verfahren können ferner das Bestimmen von Berührungsbildschirmsegmentwiderständen anhand der Signalmessungen einschließen. Die Systeme und Verfahren können anhand der Widerstände Positionen bestimmen, die den Zweifachberührungsbedienungen entsprechen. Die Systeme und Verfahren können auch anhand der Signalmessungen Positionen bestimmen.

    Abstract: The present invention provides a haptics control system that may include a driver to generate a continuous drive signal and to output the drive signal to a mechanical system on an electrical signal line, wherein the continuous drive signal causes the mechanical system to vibrate to produce a haptic effect. The haptics control system may further include a monitor, coupled to the electrical signal line, to capture a Back Electromotive Force (BEMF) signal generated by the mechanical system in the electrical signal line, to measure a BEMF signals attribute, and to transmit an adjustment signal to the driver based on the BEMF signals attribute. The driver is further configured to adjust the continuous drive signal according to the adjustment signal.

    Abstract: Systems and methods to determine locations for dual touch operations performed on a four-wire resistive touch screen. The systems and methods may include measuring signals from pairs of electrodes on each of a first and second resistive sheet of the resistive touch screen in two phases of operation. The systems and methods may further include determining touch screen segment resistances from the signal measurements. The systems and methods may determine locations corresponding to the dual touch operations from the resistances. The systems and methods may also determine locations from the signal measurements.
