20100265204 | FINGER RECOGNITION FOR AUTHENTICATION AND GRAPHICAL USER INTERFACE INPUT - A device may include a display and a processor. The display may include a first sensor for detecting a nearby finger and a second sensor for capturing an image of the nearby finger. The processor may be configured to obtain an image from the second sensor when the first sensor detects a finger, obtain identification information associated with the image, perform a function associated with the obtained identification information and a GUI object when the finger touches the GUI object shown on the display. | 10-21-2010 |
20100269038 | Variable Rate Scrolling - A method may include outputting, to a display, at least a portion of a number of items. The method may also include receiving a first user input via the display and identifying a location on the display corresponding to the first user input. The method may further include determining a scroll rate associated with the location and scrolling, via the display, the plurality of items at the determined scroll rate. | 10-21-2010 |
20100310136 | DISTINGUISHING RIGHT-HAND INPUT AND LEFT-HAND INPUT BASED ON FINGER RECOGNITION - A device may include a first sensor for detecting a finger and a second sensor for capturing an image of the finger. In addition, the device may include a processor to obtain an image from the second sensor when the first sensor detects a finger, determine whether the detected finger belongs to a right hand or a left hand based on the image, perform a function associated with the right hand when the detected finger belongs to the right hand, and perform a function associated with the left hand when the detected finger belongs to the left hand. | 12-09-2010 |

20130207733 | SELF-RESONANT CIRCUIT - A digitally-controlled oscillator circuit receives a digital value and generates a driving signal for driving an oscillator at a frequency according to the received digital value. A time-to-digital converter circuit receives a detection signal of oscillation of the oscillator, receives the driving signal, and detects a phase difference between the detection signal and the driving signal. A control circuit receives the detected phase difference and controls the frequency of the driving signal generated by the digitally-controlled oscillator circuit, such that the detected phase difference coincides with a predetermined resonant phase difference to resonate the oscillator. | 08-15-2013 |
20150020596 | VIBRATION GENERATION APPARATUS - A gyro sensor includes a vibrator and a drive circuit. A PWM drive signal is applied to a pair of electrodes of the vibrator. The drive circuit outputs a high level signal and a low level signal to the electrodes as the PWM drive signal. The high level signal and the low level signal have potentials higher and lower than that of the reference signal, respectively. The drive circuit outputs the high level signal to one of the pair of electrodes and the low level signal to the other of the pair of electrodes. | 01-22-2015 |
20150022277 | VIBRATION GENERATION APPARATUS - In a gyro sensor, a TDC detects a magnitude of vibration of a vibrator. A drive circuit (excluding the TDC) determines a duty ratio of a PWM drive signal in accordance with the magnitude of vibration so that the magnitude of vibration becomes a predetermined magnitude and outputs the PWM drive signal having the determined duty ratio. The drive circuit (excluding the TDC) includes a control circuit and a DCO. The control circuit measures time corresponding to the control value by using a gate delay time, generates the PWM drive signal having a pulse width corresponding to the control value and outputs the PWM drive signal. | 01-22-2015 |
