  • Patent number: 9339810
    Abstract: A hand-held, multi-channel pipettor has an electronically controlled motor to reposition pipette tips for different center to center spacing. Each repositionable tip fitting assembly has a cam following pin that is driven by cam tracks in a motor driven roller drum. Stationary ports for the multiple aspiration cylinders are strategically placed to simplify management of flexible tubes leading to the repositionable pipette tip fitting assemblies. The pipettor has a user interface that can be operated conveniently by one hand to reposition pipette tips. It has a pipette tip ejection mechanism with a sinusoidal stripper bar.

  • Patent number: 6462977
    Abstract: A memory device is disclosed. The memory device includes, in some embodiments, a plurality of virtual columns that may be addressed by applying an address to a plurality of address layers of the memory device. The virtual columns include addressable elements coupled to the address layers. The addressable elements allow for a data storage element associated with the virtual columns to be accessed for read/write operations when each addressable element receives a particular signal as an input from the address layer to which it is coupled.
