Abstract: A surgical instrument includes an anvil and an elongate channel. The elongate channel includes a plurality of first electrical contacts and a plurality of electrical connectors comprising a plurality of second electrical contacts, wherein the electrical connectors are spring-biased such that a gap is maintained between the first electrical contacts and the second electrical contacts. The surgical instrument further includes a staple cartridge releasably attachable to the elongate channel, wherein the staple cartridge has a cartridge body comprising a plurality of staple cavities, a plurality of staples deployable from the staple cavities into the tissue, and a plurality of third electrical contacts, wherein the attachment of the staple cartridge to the elongate channel moves the electrical connectors causing the second electrical contacts to bridge the gap and become electrically coupled to the first electrical contacts.

Abstract: An example method includes (a) generating a request to obtain log data descriptive of operation of an autonomous vehicle control system in a subject scenario, the log data indexed by an indexing parameter; (b) submitting the request to a log repository service, the log repository service configured to receive the request and serve, responsive to the request, log metadata; (c) loading, based on the log metadata and an index value of the indexing parameter, a log data sketch associated with the index value; and (d) loading, based on the log metadata and the index value, and responsive to an inspection indicator, detailed log data associated with the index value.

Abstract: A dental alloy consists essentially of 60 to 85% by weight palladium, 5 to 20% by weight copper, 3 to 15% by weight gallium, and, as modifiers, 0.5 to 7% by weight gold, 0.005 to 0.02% by weight ruthenium, rhenium, iridium or a mixture of at least two of these metals, 1 to 5% by weight tin and 0 to 2% by weight nickel, wherein the sum of the modifiers is from 5.5 to 10% by weight. Dental restorations are produced by firing ceramic onto at least part of the surface of a casting of such an alloy.
