Patent application numberDescriptionPublished
20090267664PLL CIRCUIT - In an ADPLL composed of a digital circuit, a technique improving phase difference detection in a vicinity of a phase difference of 0 (zero) is provided. A feedback loop comprises a PFD comparing phases and frequencies of a reference signal and a feedback signal, a TDC converting an output of the PFD into a digital value, a DLF removing a high frequency noise component from an output of the TDC, a DCO controlled based on an output of the DLF and a DIV frequency-dividing an output the DCO and outputting the feedback signal. An offset value is added at any portion of the feedback loop, a phase of the feedback signal is controlled and a value other than 0 is inputted to the TDC even when the ADPLL is locked.10-29-2009
20100097150PLL CIRCUIT - A technique for suppressing quantization noise generated due to digitizing an analog circuit in a PLL circuit is provided. The PLL circuit comprises: a digital phase frequency detector which detects (compares) phases and frequencies of a reference signal and a frequency-divided signal and converts the same to a digital value; a digital loop filter which eliminates high-frequency noise components from an output of the digital phase frequency comparator; a digital-analog converter which converts a digital value of an output of the digital loop filter to an analog value; an analog filter which eliminates a high-frequency noise component from an output of the digital-analog converter; a voltage controlled oscillator whose frequency is controlled based on an output of the analog filter; and a frequency divider which divides the frequency of the voltage controlled oscillator and outputs the frequency-divided signal.04-22-2010
20110064150PLL CIRCUIT WITH IMPROVED PHASE DIFFERENCE DETECTION - In an ADPLL composed of a digital circuit, a technique improving phase difference detection in a vicinity of a phase difference of 0 (zero) is provided. A feedback loop comprises a PFD comparing phases and frequencies of a reference signal and a feedback signal, a TDC converting an output of the PFD into a digital value, a DLF removing a high frequency noise component from an output of the TDC, a DCO controlled based on an output of the DLF and a DIV frequency-dividing an output the DCO and outputting the feedback signal. An offset value is added at any portion of the feedback loop, a phase of the feedback signal is controlled and a value other than 0 is inputted to the TDC even when the ADPLL is locked.03-17-2011

20090036260Reverse sprocket transfer case - A transfer case comprising a rotational input member, a rotational output member, a rotational planetary gear portion operatingly engaged between the input member and the output member, a moveable cam member selectively engagable with the planetary gear portion, whereby the rotation of the planetary gear portion is stopped when the cam member is engaged with the planetary gear portion, the rotational direction of the output member is in the same direction as the input member when the cam member is not engaged with the planetary gear portion, and the rotational direction of the output member is opposite the rotational direction of the input member when the cam member is engaged with the planetary gear portion.02-05-2009
20090047160Rotary Scissors Action Machine - A rotary machine is provided having rotating forward and rearward work members having cyclic non-constant angle motion there between, the machine includes a rotating shaft and a first gear eccentrically mounted with the rotating shaft. A reaction gear in mesh with the first gear causes the first gear to rotate with respect to the rotating shaft. First and second connecting rods are pivotally connected with the first gear. First and second crank arms are pivotally connected with the respective first and second connecting rods. First and second coaxial shafts are connected with the respective first and second first crank arms. The first shaft is connected with at least one forward work member. The second shaft is connected with at least one rearward work member.02-19-2009

20100145394UNI-PLANER BONE FIXATION ASSEMBLY - A bone fixation assembly includes a plurality of bone fixation elements that each include a bone anchor configured to be implanted into underlying bone, such as a vertebra. Each bone anchor is received in an anchor seat, and the anchor seats are joined by a fixation rod so as to operatively couple and fix the position and orientation of the vertebrae relative to each other. The bone anchor is free to rotate relative to the anchor seat, and is also free to pivot in a desired direction relative to the anchor seat.06-10-2010

20090076679METHOD AND APPARATUS TO MONITOR AN OUTPUT SPEED SENSOR DURING OPERATION OF AN ELECTRO-MECHANICAL TRANSMISSION - There is provided a method to monitor a sensing system adapted to monitor an output of an electro-mechanical transmission. This includes monitoring rotational speed of a wheel operatively connected to a driveline operatively connected to the output of the electro-mechanical transmission. A first expected output of the transmission is determined based upon the output of the first sensor. A second expected output of the transmission is determined based upon a rotational speed of a torque-generative device operatively connected to the transmission. The first and second expected outputs and an output of the sensing system adapted to monitor the output of the electro-mechanical transmission are compared.03-19-2009
