  • Micro motion poppet valve assembly for delivery of ink with large pigment particles to a writing nib and writing instrument comprising same
    Patent number: 9050850
    Abstract: A micro motion poppet valve for a writing instrument provides delivery of ink with large pigment particles to a porous writing nib with minimal nib movement and relatively light actuation forces. The micro motion poppet valve includes a nib connected to a valve stem, the valve stem being connected to a valve plug. A valve body is integrally formed with a biasing element, which biases the valve stem towards a closed position. When a user presses the nib against a writing surface the valve plug moves away from a raised valve seat located on the biasing element to allow ink to flow from an ink reservoir to the nib.

  • Integrated spectrum analyzer circuits and methods for providing on-chip diagnostics
    Patent number: 7688058
    Abstract: Spectrum analyzer circuits and methods are provided which implement “zero-IF” (direct conversion) or “near-zero IF” (or very low IF) architectures that enable implementation of integrated (on-chip) spectrum analyzers for measuring the frequency spectrum of internal chip signals. An integrated spectrum analyzer circuit, which comprises a zero IF or near-zero IF framework, enables a low-power compact design with sufficient resolution bandwidth for on-chip implementation and diagnostics of internal chip signals.
