  • Patent number: 7135146
    Abstract: A removable secondary liquid dispensing module for use with an existing, automated liquid handling system that defines a work area having a plurality of discrete work stations. Each of the work stations of the automated liquid handling system includes a lab ware site and alignment structure enabling the removable securing standardized microtiter-plates at respective lab ware site. A plate positioning mechanism is configured to move and position the microtiter plates to and from the lab ware sites of the respective work stations thereof and into engagement with the respective carrier alignment structure thereof. Further, a primary liquid dispensing device is configured for selective contact-type dispensing of discrete quantities of fluid, in the range of about one (1) microliter to about ten (10) milliliters, into the test sites of the microtiter plates secured in the respective alignment structure of the respective work station.

  • Patent number: 6983636
    Abstract: A universal calibration apparatus and method to estimate the dispense output from a low volume, non-contact, liquid dispensing systems that may be applied for every hardware configuration (e.g., tube length, orifice diameter, tip design, etc), reagent solution property and environmental condition. This same calibration technique is applied to calibrate or tune these non-contact liquid dispensing systems to dispense desired volumes (in the range of about 0.050 ?L to 50 ?L), irrespective of the hardware configuration or the solution properties. That is, the calibration technique is not dependent on any variables, but the result (the actual dispense volume) is dependant on the variable mentioned. By actuating selected pulse widths, and measuring the resulting volume, a Calibration Profile can be generated correlating the liquid volume dispensed from the orifice to the respective pulse width of the dispensing valve thereof through calibration points.

  • Patent number: 6852291
    Abstract: A hybrid valve apparatus for use with an aspiration actuator and a dispensing actuator to transfer fluid from a reservoir to a test site on a substrate surface. The hybrid valve includes a valve assembly movable between an aspiration condition and a dispensing condition, and a manifold device coupled to the valve assembly. The manifold device includes a fluid aspiration conduit having a first aspiration port in fluid communication with the aspiration actuator. On an opposite end of the aspiration conduit is a second aspiration port in selective fluid communication with the valve assembly to selectively aspirate a liquid sample slug from the reservoir into a discrete sample path when the valve assembly is in the aspiration condition. The manifold device further includes a fluid dispensing conduit having a first dispensing port in fluid communication with the dispensing actuator, and a second dispensing port in selective fluid communication with the valve assembly.

  • Publication number: 20040195063
    Abstract: A fluid coupled speed retarder generating a restraining torque on a vehicule wheel system comprises a restraining shaft (50) coupled by a viscous fluid to a wheel (32) and axle (54) system through a coupling (30) which includes an impeller (48) with radial vanes (77) connected to the restraining shaft and a housing (44) with further radial vanes (46), the housing connected for rotation with the wheel (34). A braking force is developed upon demand by a selective locking of the restraining shaft (50) from motion, the relative motion between the impeller and housing in the viscous coupling generating the barking force.

  • Publication number: 20030170903
    Abstract: An apparatus and method for delivering repetitive, precision, low volume liquid dispensing from a dispensing orifice of a non-contact liquid dispensing apparatus. An elongated communication passageway of the dispensing apparatus is defined by interior walls having one end in fluid communication with a system fluid reservoir and an opposite end terminating at the dispensing orifice. A system fluid is placed in the communication passageway extending substantially continuously from the system fluid reservoir to the dispensing orifice. A relatively small volume of gaseous fluid is aspirated through the dispensing orifice, and into the communication passageway in a manner such that the gaseous fluid extends substantially continuously across the transverse cross-sectional dimension of the communication passageway.
