Publication number: 20180252623Abstract: At least some embodiments of the technology are directed to an automated slide processing apparatus configured to apply at least one reagent to a specimen carried by a microscope slide. The slide processing station can include a support element with a support surface, at least one vacuum port, and a sealing member having a non-round shape. In an uncompressed state, the sealing member can extend upwardly beyond the support surface. In a compressed state, the sealing member can be configured to maintain an airtight seal with a backside of the microscope slide as the microscope slide is pulled against the support surface by a vacuum drawn via the at least one vacuum port.Type: ApplicationFiled: May 4, 2018Publication date: September 6, 2018Inventors: Luke Dyson-Holland, Daniel C.

Patent number: 7525960Abstract: Methods, systems and apparatus are provided which prevent frame mis-ordering in an explicitly routed network when switching from a first path to a second path. In a first embodiment, last frame and first frame markers are transmitted, and a receiver buffers all frames received between receipt of the last frame marker and the first frame marker. In a second embodiment, a last frame marker is sent to which an acknowledgement must be received before transmitting on the second path. In a third embodiment, only a first frame marker is sent. The receiver, upon receipt, signals a network card for the first path to stop forwarding frames, also buffers frames for some period. In a fourth embodiment, the merge point node forwards frames over different paths with unique markings so the outgoing card can distinguish them.Type: GrantFiled: May 9, 2002Date of Patent: April 28, 2009Assignee: Alcatel-Lucent Canada Inc.Inventors: Steve Joseph Grabner, Byoung-Joon Lee, John Willem Van Gulik
