Publication number: 20240065777Abstract: Methods and systems for performing robotically-assisted surgery in conjunction with intra-operative imaging. A method includes moving a robotic arm with respect to a patient and an imaging device to move an end effector of the robotic arm to a pre-determined position and orientation with respect to the patient based on imaging data of the patient obtained by the imaging device. The robotic arm maintains the end effector in the pre-determined position and orientation with respect to the patient and does not collide with the imaging device or with the patient when the imaging device moves with respect to the patient.Type: ApplicationFiled: November 8, 2023Publication date: February 29, 2024Applicant: Mobius Imaging, LLCInventors: Eugene A. Gregerson, Paul Sebring, Russell Stanton, Scott Coppen, Adeline Harris, Todd Furlong, Jeff Baker

Patent number: 6544719Abstract: A cost efficient method of making a lithographic printing plate precursor is disclosed, the method comprising the steps of coating a silver halide emulsion layer on a hydrophilic base which is provided with physical development nuclei; simultaneously with the preceding step, coating on the emulsion layer a solution that induces silver salt diffusion transfer reversal development of the silver halide; allowing diffusion of complexed silver ions to the physical development nuclei, thereby forming silver metal that is deposited on the hydrophilic base; a wash-off step wherein the emulsion layer is removed from the silver metal. The material thus obtained can be exposed image-wise in heat-mode, e.g. by means of an infrared laser, thereby ablating the silver metal and revealing the hydrophilic base at exposed areas. Immediately after exposure, it can be used as a lithographic printing plate without the need for a wet processing step.Type: GrantFiled: June 18, 2002Date of Patent: April 8, 2003Assignee: Agfa-GevaertInventors: Paul Coppens, Ludo Vervloet

Patent number: 6420081Abstract: The invention relates to a process for the production of a photosensitive recording material for the production of offset printing plates which comprises a dimensionally stable, two-dimensional support of a metal or metal alloy and a silver halide-containing, photosensitive layer on the front of the support and a layer which essentially consists of an organic polymeric material and is resistant to processing chemicals on the back of the support. The layer on the back of the support is applied before the photosensitive coating on the front. The invention furthermore relates to a corresponding recording material in which the layer on the back comprises at least one organic polymer having a glass transition temperature Tg of 50° C. or above. Due to the back coating, the formation of local elements between the metallic support and the silver-containing layer is reliably prevented when the recording materials are stacked.Type: GrantFiled: April 26, 2001Date of Patent: July 16, 2002Assignee: AGFA-GevaertInventors: Andreas Elsässer, Michael Dörr, Steffen Denzinger, Paul Coppens
