20130028612 | METHOD AND SYSTEM FOR MODULATING A BEACON LIGHT SOURCE IN A LIGHT BASED POSITIONING SYSTEM - In one aspect, the present disclosure relates to a method for broadcasting a modulated digital pulse recognition signal from a light source. In some embodiments, the method includes selecting one or more digital pulse recognition tones to broadcast, determining a desired brightness level for the light source, generating a digital pulse recognition signal having a duty cycle based on the desired brightness level and a frequency based on the one or more digital pulse recognition tones, and driving the output of the light source with the digital pulse recognition signal. In some embodiments, selecting one or more digital pulse recognition tones to broadcast includes generating a single periodic tone for differentiating the light source from a nearby light source. In some embodiments, selecting one or more digital pulse recognition tones to broadcast includes generating a sequence of periodic tones. | 2013-01-31 |

20130028614 | OPTICAL MODULATION DEVICE AND BIAS VOLTAGE CONTROL METHOD - An optical modulation device includes a generating circuit that generates a low-frequency signal, an average value of amplitude as an alternating-current component of the low-frequency signal being different from a center value of the amplitude of the low-frequency signal, a superimposing unit that superimposes the low-frequency signal on a data signal, an optical modulator that modulates, using the superimposition of the low-frequency signal by the superimposing unit, light from a light source and outputs a light signal, a calculating circuit that calculates an amplitude average value and an amplitude center value of a low-frequency component obtained from the light signal output by the optical modulator, and a controller that controls a bias voltage of the optical modulator such that the amplitude average value is brought closer to the amplitude center value of the frequency component calculated by the calculating circuit. | 2013-01-31 |
20130028615 | IMAGE FORMING APPARATUS - An area calculating unit calculates an image area of a toner image formed on a sheet recording member. A behavior detecting unit detects behavior of the recording member fed out of a conveying nip formed by a pair of conveying members. A thickness obtaining unit obtains thickness information of the recording member. An index calculating unit calculates an index value indicating windability of the recording member with respect to the conveying members based on the image area, the behavior, and the thickness information. | 2013-01-31 |
