  • Magnetic damping for specimen transport system
    Patent number: 8973736
    Abstract: A specimen transport system with magnetic damping and method for transporting specimens with magnetic damping are disclosed. A conveyance device transports sample carriers configured to carry specimen containers. One or more of the sample carriers include magnets. The system may also include a diverting arm having a magnet. When a first sample carrier is transported toward a second sample carrier, a first sample carrier magnet coupled to the first sample carrier repels a second sample carrier magnet coupled to the second sample carrier. When a sample carrier is transported toward a diverting arm, a diverting arm magnet of the diverting arm repels a sample carrier magnet of the sample carrier.

  • Robotic grip and twist assembly
    Patent number: 7988912
    Abstract: A microtiter plate transport device is configured to grip a microtiter plate in a first location. The microtiter plate transport device is configured to make a vertical approach to the microtiter plate and grip the microtiter plate in either a portrait orientation or a landscape orientation along either the opposing longer sides or the opposing shorter sides of the microtiter plate. The device comprises a Cartesian coordinate robot including a first gripping member and a second gripping member opposed to the first gripping member. The first gripping member and the second gripping member are supported by an arm configured to move along a vertical axis which extends between the first gripping member and the second gripping member. The first gripping member and the second gripping member are configured to rotate about the vertical axis.
