Publication number: 20220349869Abstract: A scalable, real-time, label-free, electrode- or optical-based cell monitoring system for integration into a cell culture incubator is described herein. An example system includes (1) cell culture consumables with integrated electrodes and/or optics for growing and monitoring cells, (2) incubator trays for consumable organization and recording, and (3) a system console, external to the incubator, for connecting multiple incubator trays. Without perturbing the cell culture, the system is capable of monitoring multiple culture attributes for each cell culture consumable simultaneously. These attributes can include, but are not limited to, cell growth, proliferation, morphology, media pH, or media oxygen. The system can support multiple trays, which permits monitoring dozens to hundreds of consumables simultaneously, including a mixture of consumables of various sizes. In addition to monitoring adherent cells, the disclosed technology can be readily adapted for monitoring of cell suspensions.Type: ApplicationFiled: January 27, 2020Publication date: November 3, 2022Inventors: Michael Antony CLEMENTS, Isaac Perry CLEMENTS, Thomas J.

Patent number: 10935887Abstract: A system is for processing a photosensitive flexographic printing plate having a latent image formed by image-wise exposure of an aqueous-processable photopolymer. The system can use a first aqueous processing solution with the latent image for cleaning and then washing a resulting relief image with a second aqueous processing solution, where the second aqueous processing solution is devoid of the photopolymer. A processing solution tank is configured to combine the first used aqueous processing solution with the second used aqueous processing solution to form a combined used aqueous processing solution. A processing solution removal can include: a holding tank configured for receiving the combined used aqueous processing solution; and a conduit from the processing solution tank to the holding tank. The processing solution tank includes the combined used aqueous processing solution at less than a predefined maximum volume and having the photopolymer at less than a predefined maximum concentration.Type: GrantFiled: April 10, 2020Date of Patent: March 2, 2021Assignee: MIRACLON CORPORATIONInventors: Donald L.

Patent number: 10712357Abstract: Disclosed are apparatus and methods that provide the ability to electrical stimulate a physical system, and actively eliminate interference with signal acquisition (artifacts) that arises from the stimulation. The technique implemented in the circuits and methods for eliminating interference connects a discharge path to a physical interface to the system to remove charge that is built-up during stimulation. By placing the discharge path in a feedback loop that includes a recording preamplifier and AC-coupling circuitry, the physical interface is brought back to its pre-stimulation offset voltage. The disclosed apparatus and methods may be used with piezoelectric transducers, ultrasound devices, optical diodes, and polarizable and non-polarizable electrodes. The disclosed apparatus can be employed in implantable devices, in vitro or in vivo setups with vertebrate and invertebrate neural tissue, muscle fibers, pancreatic islet cells, osteoblasts, osteoclasts, bacteria, algae, fungi, protists, and plants.Type: GrantFiled: June 15, 2017Date of Patent: July 14, 2020Assignee: Georgia Tech Research CorporationInventors: Edgar A.

Patent number: 10642157Abstract: A method for processing a photosensitive flexographic printing plate having an aqueous-processable photopolymer. A main processing unit is used to develop a relief image by removing unexposed photopolymer using an aqueous processing solution including a first dispersing agent while the photosensitive flexographic printing plate is being subjected to mechanical cleaning. Used aqueous processing solution containing the removed photopolymer is returned back into a processing solution tank. A secondary processing unit is used to wash the developed relief image with secondary aqueous processing solution including a second dispersing agent to remove debris from the developed relief image. Used secondary aqueous processing solution containing the removed photopolymer is directed into the processing solution tank. A portion of the aqueous processing solution from the processing solution tank is removed to keep a volume of aqueous processing solution in the processing solution tank below a predefined maximum volume.Type: GrantFiled: May 24, 2019Date of Patent: May 5, 2020Assignee: MIRACLON CORPORATIONInventors: Donald L.

Patent number: 7836214Abstract: A system configuration manager provides a graphical user interface that allows a system administrator to easily administer configuration settings for different computer systems and platforms on a computer network. The system configuration manager allows identifying one system configuration or a settings profile as a “model system”. Once the model system is defined, other computer systems may be compared to the model system. Differences between the selected computer systems and the model system are then displayed, and the system configuration manager may be used to update the selected computer systems with configuration settings specified in the model system. Cross-platform support is provided by a configuration mapping mechanism that maps configuration information from one platform to corresponding configuration information for another platform.Type: GrantFiled: May 16, 2008Date of Patent: November 16, 2010Assignee: International Business Machines CorporationInventors: Kenneth Edgar Brown, Gregory Richard Hintermeister, Michael Bill Murphy
