Abstract:
Systems, methods and computer-readable media are provided for determining a sequential ordering of predefined transfers for transferring an object from source points of a source array to destination points of a destination array in a laboratory automation system. For each transition to a next transfer, first and second component travel costs between current and next transfer positions are determined. A transition travel cost is determined from the first and second component travel costs. The cost of each sequential ordering of the predefined transfers is based upon an aggregate of the transition travel costs for each ordering of the transfers. The resolved sequential ordering may be based upon the sequential ordering that has the lowest cost.
Abstract:
A plurality of transport lines having driving belts are driven to transport specimen racks on which a specimen container is disposed. A single driving motor having a rotating shaft, a shaft for transmitting power of the driving motor, drives the driving belt and a plurality of pulleys transmit rotation of the shaft to the belts to drive the belts.
Abstract:
Apparatus (1) for withdrawing respective liquid samples from vials (2) which are closed by closure caps (4) includes a plurality of racks (7) for accommodating the vials (2). A device (10) including a housing (25) is slideably carried on a gantry (9) which in turn is slideably carried on guide tracks (12) to provide two degrees of movement of the device (10) for selective alignment of the device (10) with the vials (2). An abutment member (43) is driven vertically by a second gearwheel (51) by a drive shaft (27) through a first gearwheel (40) and a dog clutch (52). A cannula which is secured within a first gear rack (33) is driven vertically by the first gearwheel (40). On engagement of the abutment member (43) with the closure cap (4) of the selected vial (2), the clutch (52) decouples the second gearwheel (51) from the first gearwheel (40) so that the cannula (28) is urgeable through the closure cap (4) into the vial (2).
Abstract:
Liquid dispensing apparatus comprises a support member which supports a movably mounted dispensing member. The support member is movable between first and second positions. A single drive system causes the dispensing member to move relative to the support member to a number of dispense positions while the support member is in its first position and causes the support member to move to the second position.
Abstract:
A novel solution is proposed for processing a test tube transported on a test tube carrier by a conveyor so that spilling of the liquid in the test tube is reduced or even prevented, particularly an arrangement for sequencing and guiding travel of test tube carriers transported on at least one conveyor. The arrangement includes at least one rotatable deviator positioned to intersect the at least one conveyor. The deviator includes a horizontal deviator plate including at least one grip for receiving a test tube carrier. One contact surface is positioned vertically at a distance from the deviator plate and aligned with the grip. The contact surface is formed to contact the test tube carrier at a distance from the contact level of the grip and the carrier.

Abstract:
Apparatus (1) for withdrawing respective liquid samples from vials (2) which are closed by closure caps (4) penetratable by a pointed cannula comprises a plurality of racks (7) for accommodating the vials (2). A device (10) comprising a housing (25) is slideably carried on a gantry (9) which in turn is slideably carried on guide tracks (12) to provide two degrees of movement of the device (10) for selective alignment of the device (10) with the vials (2). An abutment member (43) which is vertically slideable in the housing (25) of the device (10) is driven by a second gearwheel (51) by a drive shaft (27) along which the housing (25) is slideably mounted through a first gearwheel (40) and a dog clutch (52). A cannula which is secured within a first gear rack (33) is driven upwardly and downwardly within the housing (25) by the first gearwheel (40) which is driven by the drive shaft (27). On engagement of the abutment member (43) with the closure cap (4) of the selected vial (2), the clutch (52) decouples the second gearwheel (51) from the first gearwheel (40) so that the cannula (28) is urgeable through the closure cap (4) into the vial (2) for withdrawing the liquid sample. The clutch (52) retains the second gearwheel (51) decoupled from the first gearwheel (40) until the cannula (28) has been withdrawn from the closure cap (4) in order to prevent displacement of the closure cap (4) during withdrawal of the cannula (28) therethrough.
Abstract:
A method of rotating a sample container carrier on a transport plane of a laboratory sample distribution system is presented. The sample container carrier is rotated by using a movement relative to a number of rotator elements. A laboratory sample distribution system being able to perform such a method and a laboratory automation system comprising such a laboratory sample distribution system are also presented

Abstract:
In the prior art, in transport lines equipped with multiple stages of transport lines driven in different directions, it was necessary that drive power sources for driving the belts of the transport lines be provided in a number equal to the number of transport lines. This led to an increased number of drive power sources and to an unavoidable increase in the power consumed by the device as a whole. In the present invention, there is adopted a mechanism for the parallel driving of a plurality of transport lines by a single drive power source, whereby the number of drive power sources needed to drive the transport lines can be reduced, as can the power consumed by the system.
