Patent number: 8942313Abstract: An open loop envelope tracking system calibration technique and circuitry are proposed. A radio frequency power amplifier receives a modulated signal. An envelope tracker power converter generates a modulated power amplifier supply voltage for the radio frequency power amplifier based on a control signal derived from the modulated signal. A first output power and a second output power of the radio frequency power amplifier are measured when the control signal is respectively delayed by a first delay period and a second delay period. A sensitivity of the output power of the radio frequency power amplifier is near a maximum near the first delay period and the second delay period. The first delay period and/or the second delay period are adjusted until the first output power substantially equals the second output power. The first delay period and the second delay period are used to obtain a calibrated fine tuning delay offset.Type: GrantFiled: February 7, 2012Date of Patent: January 27, 2015Assignee: RF Micro Devices, Inc.Inventors: Nadim Khlat, Karl Francis Horlander

Publication number: 20120225019Abstract: A two colour fluorescent assay and a kit are described that permit the determination of live and dead parasitic or non-parasitic worms, for example helminths. The assay permits screening for the effect of one or more agents or an event on the viability of a parasitic or non-parasitic worm. In one example, the assay comprises (a) providing a sample comprising one or more parasitic or non-parasitic worms; (b) contacting the parasitic or non-parasitic worms with a concentration of fluorescein diacetate sufficient to yield detectable green fluorescence in any live parasitic or non-parasitic worms present in the sample and a concentration of propidium iodide sufficient to yield detectable red fluorescence in any dead parasitic or non-parasitic worms present in the sample; and (c) detecting the red and green fluorescence of the parasitic or non-parasitic worms.Type: ApplicationFiled: September 13, 2010Publication date: September 6, 2012Inventors: Emily Peak, Karl Francis Hoffmann

Patent number: 8200071Abstract: A record and replay apparatus comprises a transducing unit for reproducing a digital signal from a medium. A control unit controls a reproduction mode of the apparatus. A decoding is coupled to the transducing unit for decoding the digital signal and deriving therefrom a signal indicative of a specific picture type. The reproduction mode has a first period of reproduction at a normal play speed and a second period of reproduction at a speed greater than the play speed. The first and second periods alternating with the first period initiated responsive to the signal indicative of a specific picture type. In a further arrangement a first transducing unit records an MPEG signal. A control unit generates a signal, indicating an intra coded frame occurrence in the MPEG bit stream, which is recorded by a second transducing unit together with a servo reference signal.Type: GrantFiled: October 8, 1997Date of Patent: June 12, 2012Assignee: Thomson LicensingInventors: Harold Blatter, Karl Francis Horlander, Michael Joseph McLane

Patent number: 7017171Abstract: A method for operating a video processing system by receiving initial copyright information from a first source, storing the initial copyright information, receiving updated copyright information from a second source, and updating the stored copyright information in response to the updated copyright information. For example in one embodiment of the present invention, the initial copyright information for a program is received from an electronic program guide and updated copyright information is received along with the selected program. The video processing system may be programmed to operate in a first operating mode in response to the initial copyright information and the operating mode of the video processing system may be switched to a second operating mode in response to the updated copyright information.Type: GrantFiled: March 18, 1999Date of Patent: March 21, 2006Assignee: Thomson LicensingInventors: Karl Francis Horlander, Michael Francis Kvintus, Jr., Keith Reynolds Wehmeyer, Robert Howard Miller

Patent number: 6844943Abstract: A system and method for eliminating absent or poor quality video sections from a video recording, such as a second generation of video recording. Synchronizing pulses associated with a video signal to be recorded are analyzed to determine whether a video signal is present and, further, to determine whether the video signal is not distorted (i.e., non-trick play mode). A recording device is selectively paused in response to the absence of a valid video signal or the presence of a video signal that is distorted, of poor quality or otherwise not worth recording.Type: GrantFiled: November 29, 2000Date of Patent: January 18, 2005Assignee: Thomson Licensing SAInventors: Harold Rhea McKee, Karl Francis Horlander, John Homer Furrey, Joseph Craig Engle

Patent number: 6801246Abstract: A signal processing method and apparatus in which a horizontal and/or vertical synchronizing signal related to a received video signal is monitored to determine if a relatively large change has occurred in the respective vertical and/or horizontal time period such that a change in video signal source may have occurred. Upon the detection of such a change, the operation of a phase lock loop (PLL) such as horizontal phase lock loop (HPLL) and/or vertical phase lock loop (VPLL) circuit is adapted as appropriate.Type: GrantFiled: February 27, 2001Date of Patent: October 5, 2004Assignee: Thomson Licensing, S.A.Inventor: Karl Francis Horlander

Patent number: 6650824Abstract: A method for operating a video recording apparatus in one of a digital recording mode and an analog recording mode. The method involves recording a digital video bit stream in the digital recording mode and switching to the analog recording mode for recording the corresponding analog video signal in response to a fault condition. For example, the fault conditions may occur in response to improper copyright information, an analog recording media being loaded into the video recording apparatus or the digital video bit stream being absent while the video recording apparatus operates in the digital recording mode. The fault condition may be indicated to a user and switching to a different mode, such as the analog recording mode, may occur in response to receiving a user initiated command responsive to the indicated fault condition.Type: GrantFiled: March 18, 1999Date of Patent: November 18, 2003Assignee: Thomson Licensing S.A.Inventors: Karl Francis Horlander, Michael Francis Kvintus, Jr., Keith Reynolds Wehmeyer, Robert Howard Miller

Patent number: 6507953Abstract: A method for scheduling events between first and second video processing devices coupled together wherein each device having at least one event timer for storing a scheduled event. The method involves programming first event information into the first device, comparing the first event information to each event previously scheduled in the first device for determining conflicts therebetween, sending a message representing the first event information to the second device, comparing the first event information to each event previously scheduled in the second device for determining conflicts therebetween. A user may be provided with information regarding conflicts and may be notified that a password is required for the first event and the respective event timer is enabled in response to receiving the password entered into the first device.Type: GrantFiled: November 30, 1998Date of Patent: January 14, 2003Assignee: Thomson Licensing S.A.Inventors: Karl Francis Horlander, Michael Francis Kvintus, Jr., Keith Reynolds Wehmeyer, Robert Howard Miller
