Patent number: 8298833Abstract: A bridge (30) comprises a first inlet port (31) at the end of a capillary, a narrower second inlet port (32) which is an end of a capillary, an outlet port (33) which is an end of a capillary, and a chamber (34) for silicone oil. The oil is density-matched with the reactor droplets such that a neutrally buoyant environment is created within the chamber (34). The oil within the chamber is continuously replenished by the oil separating the reactor droplets. This causes the droplets to assume a stable capillary-suspended spherical form upon entering the chamber (34). The spherical shape grows until large enough to span the gap between the ports, forming an axisymmetric liquid bridge. The introduction of a second droplet from the second inlet port (32) causes the formation of an unstable funicular bridge that quickly ruptures from the, finer, second inlet port (32), and the droplets combine at the liquid bridge (30).Type: GrantFiled: February 7, 2007Date of Patent: October 30, 2012Assignee: Stokes Bio LimitedInventors: Mark Davies, Tara Dalton, Kieran Curran

Patent number: 8252233Abstract: A sample-processing system that improves total system processing efficiency, and reduces a sample-processing time, by establishing a functionally independent relationship between a rack conveyance block with rack supply, conveyance, and recovery functions, and a processing block with sample preprocessing, analysis, and other functions. A buffer unit with random accessibility to multiple racks standing by for processing is combined with each of multiple processing units to form a pair, and the system is constructed to load and unload racks into and from the buffer unit through the rack conveyance block so that one unprocessed rack is loaded into the buffer unit and then upon completion of process steps up to automatic retesting, unloaded from the buffer unit. Functional dependence between any processing unit and a conveyance unit is thus eliminated.Type: GrantFiled: December 23, 2008Date of Patent: August 28, 2012Assignee: Hitachi High-Technologies CorporationInventors: Hitoshi Tokieda, Yoshimitsu Takagi, Takeshi Shibuya, Masashi Akutsu

Patent number: 7987022Abstract: The present invention provides control methods, control systems, and control software for microfluidic devices that operate by moving discrete micro-droplets through a sequence of determined configurations. Such microfluidic devices are preferably constructed in a hierarchical and modular fashion which is reflected in the preferred structure of the provided methods and systems. In particular, the methods are structured into low-level device component control functions, middle-level actuator control functions, and high-level micro-droplet control functions. Advantageously, a microfluidic device may thereby be instructed to perform an intended reaction or analysis by invoking micro-droplet control function that perform intuitive tasks like measuring, mixing, heating, and so forth. The systems are preferably programmable and capable of accommodating microfluidic devices controlled by low voltages and constructed in standardized configurations.Type: GrantFiled: October 13, 2005Date of Patent: July 26, 2011Assignee: Handylab, Inc.Inventors: Kalyan Handique, Karthik Ganesan, Sundaresh N.

Patent number: 7966097Abstract: A demand initiated method for regenerating a water softener which operates the softener ion exchange bed over a capacity range in which the resin is most efficiently restored by exposure to brine. The reserve capacity of the softener is adjusted in response to the amount of softening capacity used since the last regeneration, as is the quantity of saturated brine to be used for the next regeneration, which is scheduled when the reserve capacity is exceeded, or the remaining available capacity will not be adequate for expected usage on the next day of the week. The method schedules a regeneration when the amount of exchange capacity of the resin bed used since the last regeneration plus the variation of exchange capacity used on the next day plus the average exchange capacity of the resin bed used on the next day is greater than the selected design exchange capacity.Type: GrantFiled: February 28, 2006Date of Patent: June 21, 2011Assignee: Ecowater Systems LLCInventor: Jeffrey A.
