  • Publication number: 20180045702
    Abstract: An automatic filter changer that automatically inserts and removes a filter from a fluidic path. Filters are introduced into the automatic filter changer in stacks. The lead filter and each stack is removed from its respective stack one by one by a filter separator. The separated filters are deposited onto a shuttle plate which moves the filters into their respective fluidic paths. Fluid couplers connect to each filter to complete their respective fluidic paths and allow fluids to be filtered before sampling. Once collection of the samples is complete, the filters are removed from the fluidic path and discarded or saved for reuse. The shuttle path is returned to its original position to receive new filters to repeat the process again. A graphic user interface is provided to allow the user to program a specific set of instructions to automate the entire process.

  • Publication number: 20090042281
    Abstract: High throughput compound profiling systems, and related devices and sub-systems that can be used to perform various compound profiling processes are provided. These systems typically include work perimeters that are organized for optimum efficiency and processing accuracy. Further, these systems are readily adaptable for performing a wide array of assays, as many different system components are easily incorporated or interchangeable in a particular system. System components that are provided by the invention include cell culture dissociators, which can be used, e.g., to effect cell wetting, dissociation, and/or agitation applications. In some embodiments, these cell culture dissociators are included as components of automated cell culture passaging stations. Dispensing devices that permit on-the-fly fluid temperature regulation are also provided. In addition, various compound profiling methods, cell dissociation methods, uniform cell concentration dispensing methods, among other processes, are also provided.

  • Publication number: 20080253927
    Abstract: The present invention provides a system and method for high throughput processing using sample holders. The system has a plurality of work perimeters, with a rotational robot preferably associated with each work perimeter. At least one transfer station area is provided between adjacent work perimeters to facilitate robotic transfer of sample holders from one work perimeter to another area. Each work perimeter typically includes a plurality of defined station locations, with each station location positioned to be accessible by the robot associated with that area. In addition, each station location is typically configured to receive a device, such as an automated instrument or a holding nest. Device components are arranged at selected station locations according to specific application requirements to provide a flexible, robust, reliable, and accurate high throughput processing system.

  • Patent number: 7283743
    Abstract: Systems and methods for actively monitoring and managing the integrity of an optical fiber communications link. The optical fiber link integrity is monitored to guard against intrusions and other security breaches. In one embodiment, a local and a remote active monitoring system are coupled by four fiber paths that provide primary and back-up transmit and receive paths between communication equipment. In one embodiment, a security light signal is transmitted using a secondary wavelength that differs from the wavelength used to transmit a user data light signal and travels in an opposite direction relative to the user data light signal. An active monitoring system monitors both administrative information contained within the security light signal and the intensity of the security light signal to manage the integrity of the fiber optic link. Methods are provided to characterize events impacting the fiber optic link integrity.

  • Publication number: 20040157322
    Abstract: A fermentation apparatus is constructed to produce a known and repeatable amount of untainted fermentation product using multiple fermentation vessels. To facilitate further processing compatible with other product processing steps, the fermentation apparatus has an array of sample vessels arranged in a container frame. The container frame is configured to hold the sample vessels during fermentation and to transport the vessel array to or from another processing station. Corresponding to the number of sample vessels in the sample vessel array, a cannula array is configured such that each cannula may be placed inside a sample vessel. The cannula array is attached to a gas distributor that delivers oxygen and/or one or more other gases from a gas source through the cannula into the sample vessel. Because the fermentation volume for each individual sample vessel is smaller than a bulk fermentation apparatus, the fermentation product yields are predictable and cell growth rates can be effectively optimized.
