  • Hand held inkjet pen
    Patent number: 6981768
    Abstract: A hand held inkjet pen includes a housing, an ink reservoir, an inkjet printhead and a spacer. The ink reservoir is located within the housing. The inkjet printhead is located toward a distal end of the housing, and includes a plurality of nozzles for ejecting ink received from the reservoir. The spacer is located at the distal end of the housing for contacting a media sheet. Force applied to the spacer selects an on state for controlling ejection of ink from the plurality of nozzles.

  • Frequency detector for frequency locked loop
    Patent number: 4801894
    Abstract: A frequency synthesizer circuit employs a frequency detector that receives a reference frequency signal and a variable frequency signal and that generates a difference output signal after detecting a complete cycle of the one of the reference frequency and variable frequency signals that is of the highest frequency, the difference output signal being a function of the difference between the frequency of the reference signal and the frequency of the variable frequency signal.
