Listing for abstract view: USPTO application #, Title, Abstract excerpt,Patent Agent. Listing format for list view: USPTO National Class full category number, title of the patent application. 05/28/2009 > patent applications in patent subcategories. archived by USPTO category
20090134948 - Pulse modulation method: A pulse modulation method divides code comprising 4N-bit data into 2-bit units of data. For each pulse signal having a fixed pulse width tw, a code modulated signal is generated by pausing between pulse pause intervals Tr. An adjusted time width of between ½ and 1 times the fixed pulse... Agent: Darby & Darby P.C.05/21/2009 > patent applications in patent subcategories. archived by USPTO category
20090128247 - Intermittent operation circuit and modulation device: There is provided a small-size, low-power-consumption intermittent operation circuit capable of obtaining an output waveform having a rapid rise and fall. The intermittent operation circuit includes an active circuit (106), a first control signal generation circuit (101) for generating a first control signal (S1) for controlling the operation start and... Agent: Dickinson Wright PLLC James E. Ledbetter, Esq.05/14/2009 > patent applications in patent subcategories. archived by USPTO category
20090121801 - Pulse width modulation driving device: A pulse width modulation (PWM) driving device for generating a driving signal to a load is provided. A driving unit provides the driving signal according to a PWM signal and a control signal. A pulse generating unit generates the PWM signal according to a feedback signal from the load. A... Agent: Thomas, Kayden, Horstemeyer & Risley, LLP05/07/2009 > patent applications in patent subcategories. archived by USPTO category
20090115544 - Systems and methods for dqpsk modulator control using selectively inserted dither tone: DQPSK modulator control is provided using a single monitor photodiode with a selectively injected dither tone. The dither tone signal is sequentially injected into arm modulators and/or to a modulator driver port in time slots. A tapped signal at the output of the modulator is monitored synchronously with injected dither... Agent: Clements Bernard PLLC
20090115545 - Nonlinear transmission line modulator: A modulator is provided that comprises a nonlinear transmission line (NLTL) that is bias modulated by a baseband signal. A given logic state of the baseband signal determines a delay amount of a first carrier signal through the NLTL. The modulator further comprises an impulse forming network (IFN) that includes... Agent: Tarolli, Sundheim, Covell & Tummino L.L.P.
20090115546 - Modulator comprising a dual-frequency oscillator and a synthesizer: Oscillators (10) which oscillate at a fundamental frequency also generate harmonics. The fundamental frequency or a lower harmonic is used for feedback purposes, and a harmonic higher than either the fundamental frequency or the lower harmonic is used for output purposes. As a result, the oscillators (10) operate at a... Agent: Philips Intellectual Property & StandardsPrevious industry: Oscillators
Next industry: Wave transmission lines and networks
