Patent number: 8254601Abstract: An impedance matched connection is provided between a load and a power source that outputs signals within a predetermined frequency range. A coaxial line has a predetermined characteristic impedance, an inner conductor, an outer conductor, and an insulator between the conductors. Each conductor has a first end electrically connectable to output terminals of the power source. A compensation circuit has an adjustable impedance, a first terminal electrically connected to a second end of the inner conductor and to a first terminal of the load, and a second terminal electrically connected to a second end of the outer conductor and to a second terminal of the load. The compensation circuit is adjustable to attain, for a pulse having a rise time/fall time faster than the rise/fall times associated with the predetermined range of frequencies, a combined impedance and load that is substantially equal to the characteristic impedance of the coaxial line.Type: GrantFiled: February 29, 2012Date of Patent: August 28, 2012Assignee: Crestron Electronics Inc.Inventors: George Feldstein, Krunoslav Esteban Draganovic

Patent number: 6489169Abstract: A method for feeding containers into an analytical instrument whereby a sample handler moves and positions racks, containing sample tubes, into, within and out of the analytical instrument. The sample handler has an in-feed and out-feed that advance sample tube racks using a walking beam mechanism. The racks are seated within the in-feed and are transported onto a cross-feed. The cross-feed moves the racks to a position behind the out-feed where the walking beam mechanism moves the tube racks out of the analytical instrument.Type: GrantFiled: February 15, 2000Date of Patent: December 3, 2002Assignee: Bayer CorporationInventors: Beri Cohen, Thomas W.

The sample handler has an in-feed and out-feed that advance sample tube racks using a walking beam mechanism. The racks are seated within the in-feed and are transported onto a cross-feed. The racks and tubes contained thereon are moved past detection devices that identify the samples and measure various properties thereof.

The sample handler has an in-feed and out-feed that advance sample tube racks using a walking beam mechanism. Sample tube racks are seated within the in-feed and are transported onto a cross-feed. The cross-feed comprises a movable track having a platform mounted thereto. The platform includes spring loaded gripper fingers that engages and secures the sample tube rack to the platform. The cross-feed moves the sample tube racks to a point where they are accessed by the analytical instrument. Thereafter, the cross-feed moves the sample tube racks to a position behind the out-feed where the walking beam mechanism moves the tube racks out of the analytical instrument.Type: GrantFiled: February 15, 2000Date of Patent: August 27, 2002Assignee: Bayer CorporationInventors: Beri Cohen, Thomas W.

Patent number: 6374982Abstract: A robotic arm has a pair of gripper fingers designed to grip a variety of containers, including capped and uncapped test tubes as well as containers having unique gripping means. The fingers each have upper and lower projections separated by a groove, the respective projections facing each other when mounted to grippers on the robotic arm. The projections and groove serve to firmly hold the containers as well as self-align the unique gripping means on initially unaligned containers within the fingers as the fingers close around the containers. The fingers have clearance to avoid contact with caps on capped test tubes. Stops are provided at the top of each finger to engage one another and prevent fully closed fingers from deforming. The robotic arm may be transported along a rail mounted above the instrument and a gripper assembly, having a gripper arm, mounted to the robotic arm may be rotated above the instrument to move the container to various locations within the instrument.Type: GrantFiled: March 24, 2000Date of Patent: April 23, 2002Assignee: Bayer CorporationInventors: Beri Cohen, Thomas W.

Patent number: 6331437Abstract: An analytical instrument has a sample handler for inputting racks of containers, including various types and sizes of test tubes, both capped and uncapped, and inserts, into the instrument. The sample handler has an infeed, an outfeed and a cross-feed between the infeed and outfeed. The infeed and outfeed advance the racks of containers using walking beam mechanisms which lift the racks by tabs on the right and left sides of the rack, which are positioned at a substantially identical height. Racks input into the infeed are transferred by the walking beam mechanism to a track on the cross-feed. They are then pushed, by a transport subassembly having a platform with pivotable pusher fingers to cam the rack and to push it in only one direction, from behind the infeed to a fixed position behind the outfeed.Type: GrantFiled: July 14, 1998Date of Patent: December 18, 2001Assignee: Bayer CorporationInventors: Beri Cohen, Thomas W.
