Abstract: Connector inserts having reliable contacts, as well as connector receptacles having improved magnetic circuits for use in electronic devices having a thin form factor. These and other examples can provide connector receptacles that can be easily aligned to an opening in an electronic device, as well as connector inserts and connector receptacles that can be readily manufactured.

Abstract: A method and apparatus for automatically removing used magazines with used pipette tips from a pipetting head in an automated pipettor, and for automatically inserting an unused or cleaned magazine with unused or cleaned pipette tips in their place. The apparatus includes a gripping mechanism having two separate and independently operated gripping heads, one gripping head being associated exclusively with unused or cleaned magazines and pipetting tips, and the other gripping head being associated exclusively with used magazines and pipette tips. A transporting mechanism is provided for moving the gripping heads between the pipetting head, a disposal mechanism, and a supply of unused or cleaned magazines and pipetting tips. The supply preferably includes a carousel with a multiplicity of locations for storing unused or cleaned magazines and tips in a vertical alignment. The carousel is rotated so that a compartment containing unused or cleaned magazines and tips is in alignment with an opening in the carousel.
