  • Patent number: 6096368
    Abstract: Bead transporter chucks for selective pick up and discharging of polymer beads for chemical synthesis or analysis, whereby repulsive field conductors are arranged around bead electrodes used for selectively attracting and retaining beads. Problems of bead control are addressed by adding repulsive fields to help guide and direct beads to desired or designated bead collection zones. The repulsive electrodes create non-uniform electric fields that control, focus, and deflect charged beads in the vicinity of the bead collection zone, helping prevent multiple bead retention at intended bead collection zones. For better bead control, and allowing manipulation of beads with higher charge/mass ratios, dielectric material may be positioned around the bead electrode and between the bead electrode and the repulsive field conductor. Multiple bead electrodes may be provided to form two or more bead collection zones, and these may selectively addressed and controlled (e.

  • Patent number: 6074688
    Abstract: Method for electrostatically depositing select doses of medicament powder at select locations on a substrate. Specifically, the apparatus contains a charged particle emitter for generating charged particles that charge a predefined region of a substrate and a charge accumulation control circuit for computing the amount of charge accumulated upon the substrate and deactivating the emitter when a selected quantity of charge has accumulated. Additionally, a triboelectric charging apparatus charges the medicament powder and forms a charged medicament cloud proximate the charged region of the substrate. The medicament particles within the medicament cloud electrostatically adhere to the charged region. The quantity of charge accumulated on the substrate at the predefined region and the charge-to-mass ratio of the medicament powder in the cloud control the amount (dose) of medicament deposited and retained by the substrate.
