Ken Tseung has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20060263268
    Abstract: An automated staining system and a reagent container designed for use with the automated staining apparatus. The reagent container includes a reagent containment section capable of containing a volume of a reagent. The reagent containment section includes an upper wall and a base wall that are spaced apart along an axis. The base wall includes a well having a nadir that is aligned axially with an access opening in the upper wall so that a reagent probe entering the opening parallel to said axis will travel toward the nadir. In another aspect of the invention, the reagent container may include a two-dimensional data element containing reagent information. The staining apparatus may include one removable drawer for holding reagent containers and another removable drawer holding slides.

  • Publication number: 20060120925
    Abstract: An apparatus for treating slides has a base with a cavity, and a heater is located on a surface of the cavity. A tank, which supports a slide rack with the slides submerged in a slide treatment solution, is placed in the cavity with a tank surface immediately adjacent the heater. A temperature sensor is mounted in the base and is operable to provide a feedback signal representing a temperature of the liquid in the tank. A cover is removably hinged on the base to cover the tank. A control system is connected to the heater and the temperature sensor and has a user input/output that is operable to select a set temperature of the liquid and a cycle time.

  • Patent number: 5439649
    Abstract: An automated microscope-slide-staining apparatus, having a supporting framework; an arm moveable in three dimensions attached to the framework; apparatus for moving the arm; a hollow tip head located on the arm; apparatus for alternatively supplying positive or negative gas pressure to the hollow tip head; a removable wash/blow tip having an exit slit, the wash/blow tip being adapted to be removably attached to the hollow tip head by a preselected movement of the arm; a wash/blow tip holder at a first fixed location on the framework; a reagent application tip holder at a second fixed location on the framework for holding a reagent application tip, the reagent application tip being adapted to be removably attached to the hollow tip head by a preselected movement of the arm; a reagent container holder at a third fixed location on the framework; a microscope slide holder at a fourth fixed location on the framework, the microscope slide holder being adapted to removably contain the microscope slide; and control a
