  • Patent number: 10993772
    Abstract: A system and method for integrated table motion includes a device. The device includes an articulated arm having joints and a distal portion distal to the joints and a control unit. To support integrated motion with a separate table, the control unit is configured to receive a table movement request from the table, determine whether allowing the table movement request would result in a first joint of the joints being at a range of motion limit, allow the table to perform the table movement request based on determining that allowing the table to perform the table movement request would not result in the first joint being at the range of motion limit, track movement of the table due to performing the table movement request, and maintain, using the joints and based on the tracked movement, a position and/or an orientation of the distal portion relative to the table.

  • Patent number: 10894157
    Abstract: A method of producing an electrode for use in the manufacture of electrolytic capacitors for implantable cardioverter defibrillators comprises first growing a hydrate layer and/or formed oxide layers of the foil, applying a laser beam to portions of the foil to ablate the aluminum oxide foil surface before etching in order to induce etching in the specific areas, and then, etching the foil. The laser marks the oxide layer in a pulsed spot pattern through the hydrate layer and/or formed oxide layer leaving a dimpled nascent aluminum surface. The oxide layer left behind is a mask and the fresh aluminum areas are the high etching activation sites. After marking the aluminum oxide foil surface, the foil may be electrochemically etched in an electrolyte containing chloride and/or various oxidative species.
