Patents by Inventor Andreas Theodorus Engelen

Andreas Theodorus Engelen 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).

  • Patent number: 11127560
    Abstract: The invention relates to a charged particle microscope (CPM) that at least includes a sample holder, for holding a sample, and a manipulator device arranged for transferring a lamella created in said sample out of said sample, wherein said manipulator device comprises a first elongated manipulator member with a first outer end, and a second elongated manipulator member with a second outer end. The outer ends are movable for mechanically gripping and releasing said lamella. In embodiments, the elongated manipulator members comprise off-set parts that increase manoeuvrability, accessibility, and monitorability of the manipulator device during use.
    Type: Grant

  • Patent number: 9142384
    Abstract: The invention relates to a method of welding a vitreous biological sample at a temperature below the glass transition temperature of approximately ?137° C. to a micromanipulator, also kept at a temperature below the glass transition temperature. Where prior art methods used IBID with, for example, propane, or a heated needle (heated resistively or by e/g/laser), the invention uses a vibrating needle to locally melt the sample. By stopping the vibration, the sample freezes to the micromanipulator. The heat capacity of the heated parts is small, and the amount of material that stays in a vitreous condition thus large.

  • Patent number: 8921785
    Abstract: The invention relates to an assembly of a cooperating capillary and cap for containing an aqueous solution in an inner volume of the capillary. The assembly is used in a high pressure freezer in which the aqueous solution is frozen at a high pressure to form an amorphous frozen sample at a cryogenic temperature. The cap forms a closure at one end of the capillary, and the part of the cap that is in contact with the inner volume of the capillary has an indent; as a result of which the cap, after freezing the aqueous solution, can be removed from the capillary and a free standing pillar of frozen aqueous material extends from the capillary.

  • Patent number: 8754384
    Abstract: Described is a system and method for in situ sample preparation and imaging. The system includes a multi-axis stage 100 having a bulk stage 110 and a grid stage 150 with various degrees of freedom to allow for sample preparation. In some embodiments, a focused ion beam system is used to prepare a lamella on the bulk stage 110. The lamella can then be transferred to the grid stage 150 from the bulk stage 110 without needing to move the multi-axis stage 100 from the focused ion beam system.

  • Patent number: 8598524
    Abstract: An apparatus for loading a sample into a particle-optical instrument that includes a slider bearing having a base plate in contact with the vacuum chamber at one side, said base plate showing a first through-hole in contact with the vacuum chamber, and a second plate, one side of the second plate in contact with the base plate, said second plate also showing a through-hole, where the faces of the base plate and the second plate facing each other are sufficiently smooth to form a non-elastomeric vacuum seal and where the second plate is a flexible plate and the face of the flexible plate opposite to the base plate is equipped to seal against a cup equipped to hold a sample.
