Patent number: 7417513Abstract: A system and method for modulating a phase component of an electromagnetic signal includes a phase/frequency detector having first and second inputs and an output. The first phase/frequency detector input may be configured to receive a reference signal. The system may include an oscillator having an input and an output. The oscillator may be configured to generate a desired oscillator output signal at its output. A divider may be configured to receive the oscillator output signal. The divider may have a divider count input and a divider carryout output that may be connected to the second phase/frequency detector input. A loop filter may be connected in series between the phase/frequency detector output and the oscillator input. The loop filter has a transfer function including at least two frequency response rate change points, where each of the frequency rate change points corresponds to a pole or a zero in the transfer function.Type: GrantFiled: August 17, 2005Date of Patent: August 26, 2008Assignee: M/A-COM, Inc.Inventors: Walid Khairy Mohamed Ahmed, David Bengtson

Patent number: 7343138Abstract: The invention relates to for processing an electromagnetic input signal, wherein the signal is passed through an input to be modified across a plurality of modifying segments using a characteristic of the signal, and wherein the plurality of segments have a plurality of states controlled by a control signal, by determining a reference impedance for the input for one or more states of the plurality of segments; and adaptively adjusting impedance of the input toward the reference impedance. This may be accomplished for example, by using a matching circuit comprising one or more selected from the group consisting of a digital signal processor, a microprocessor, a logic circuit, an integrated circuit, a phase shifter, a resistor, a variable inductor, and a variable capacitor. The matching circuit determines shifts in impedance of the input after a change in state of the segments; and adaptively adjusts the impedance based upon the shift.Type: GrantFiled: December 8, 2003Date of Patent: March 11, 2008Assignee: M/A-COM, Inc.Inventors: David Bengtson, Dale Scott Douglas

Patent number: 6139046Abstract: A stroller includes a latching mechanism for a foldable frame that is remotely actuated through a sliding actuator on an upper frame member of the stroller frame. The sliding actuator is attached via a wire to pins which can be selectively placed in or out of engagement with a notch defined on a surface associated with the lower front frame member. A seat assembly on the stroller includes a seat back which is pivotably attached to the adjacent seat portions to allow the seat back to be folded when the stroller is folded. A canopy with dual extendable visors is removably attachable to the seat assembly. The canopy can be moved pivotably to a fully forward, fully backward, or any intermediate position, and the dual extendable visors on either end thereof can be selectively retracted or extended so as to achieve the desired amount of blocking of the sun and elements as well as to provide the desired ventilation.Type: GrantFiled: September 25, 1997Date of Patent: October 31, 2000Assignee: Evenflo Company, Inc.Inventors: Mark W. Aalund, William B. Stephens, Theodore Brent Freese, Alan David Bengtson, Cynthia R. Nelson, Donna K. Finney
