Publication number: 20130284761Abstract: A fluid dispensing apparatus includes a fluid reservoir and a dispensing assembly. The dispensing assembly includes a housing and a deformable member that define a metering chamber that is configured to receive a predetermined volume of fluid from the fluid reservoir. The deformable member is deformed from a rest position to an eject position and the deformation causes the volume of the metering chamber to change which results in a change in fluid pressure within the metering chamber. An increase in the fluid pressure within metering chamber causes a predetermined volume of fluid within the metering chamber to be ejected and a decrease in the fluid pressure within the metering chamber causes fluid to be drawn into the metering chamber from the reservoir.Type: ApplicationFiled: June 10, 2013Publication date: October 31, 2013Inventor: Xuan S.

Patent number: 7767152Abstract: A sample, or slide, retaining tray includes a reagent reservoir, or recess, and a reaction chamber. A slide, or other sample container, can be positioned on the sample retaining tray as desired, with a tissue specimen face down, between a platen on the tray and the slide. A reagent from the reservoir is rendered flowable, such as by heating, and flows from the reservoir into the reaction chamber. Optionally, reagents or other fluids can be provided from above, by dripping onto a drip surface of the sample retaining tray, or below via an inlet port in the platen.Type: GrantFiled: February 3, 2006Date of Patent: August 3, 2010Assignee: Sakura Finetek U.S.A., Inc.Inventors: Ronald H.

Patent number: 7744817Abstract: A manifold assembly that directs fluid to and from individually selectable sample receiving trays of a tissue processing system includes a manifold, fluid conduits machined in the manifold, and valves that may be selectively configured to provide a direct fluid path to or from a particular tray. The valves are controlled by a controller that positions each valve such that a desired path is created. Pressure is created in supply and/or drain bottles to supply or drain fluid from the trays supported by the manifold assembly. Independently operated heaters are provided on the manifold assembly to heat the trays to desired temperatures. Thermoelectric cooling elements may also provided to cool the heaters and/or trays.Type: GrantFiled: February 6, 2006Date of Patent: June 29, 2010Assignee: Sakura Finetek U.S.A., Inc.Inventor: Xuan S.

Patent number: 7530557Abstract: A multi-axis chuck that rotates about at least two axes. Preferably, the axes are perpendicular. The multi-axis chuck includes a first portion, second portion, and third portion. Rear sides of the first portion and the second portion have a first mating portion that mates with a second mating portion provided on the second portion and the third portion, respectively. The mating portions enable the first portion and the second portion to be rotated about the axes. Preferably, the first portion rotates about a first axis independently of the second and third portions. Rotation of the second portion about a second axis preferably also rotates the first portion about the second axis. The multi-chuck is operatively connected to a motor, controller, and sensors. A user inputs a desired position into the controller that controls the motor. The motor rotates the multi-axis chuck to the desired position. The sensors are used to determine a position of the multi-axis chuck.Type: GrantFiled: January 29, 2007Date of Patent: May 12, 2009Assignee: Sakura Finetek U.S.A., Inc.Inventors: Xuan S.

Patent number: 6502746Abstract: A device, system and method for extracting deposited items from a secure enclosure, such as the envelope bin of an ATM/CAT safe, makes use, for example, of computer hardware and software applications, as well as one or more secure access devices, card devices, transponder devices, input devices, control mechanisms, transport bins, and transport devices, to modify or field retrofit an existing ATM/CAT to enable removal of items without opening the safe door. The modified ATM/CAT enables a service person, for example, to enter a retrieval request, which is received by a control device, and the control device automatically opens an access port of shutter of the ATM/CAT safe and automatically activates a transport mechanism to transport items out of the safe to be received by the service person or a secured access bin docked, for example, with the access port.Type: GrantFiled: August 19, 1999Date of Patent: January 7, 2003Assignee: Citicorp Development Center, Inc.Inventors: Cuong D.

Patent number: 6206284Abstract: An automated bank teller machine (ATM) is provided which is characteristically easy to configure, regardless of whether a replenish-from-the-front (RFTF) configuration or a replenish-from-the-rear (RFTR) configuration is chosen. In particular, the ATM according to the present invention includes a security chest module, a top module, and an interface module. These components are common to both configurations can be built and stored in advance, and can be thereafter configured as desired. In another embodiment, an ATM is provided that permits more than one customer to use the ATM at the same time.Type: GrantFiled: November 16, 1999Date of Patent: March 27, 2001Assignee: Citicorp Development Center, Inc.Inventors: Cuong Do, Avery Bairamian, Xuan S.
