Abstract: Methods and systems are described for obtaining a plurality of BER-specific correction values by comparing a first set of BER values obtained by sampling, at a sampling instant near the center of a signaling interval, a non-DFE corrected received signal with a second set of BER values obtained by sampling a DFE-corrected received signal at the sampling instant. A set of eye-scope BER measurements are obtained, each eye-scope BER measurement having a sampling offset relative to the sampling instant, a voltage offset value representing a voltage offset applied to alter a decision threshold, and an eye-scope BER value. A set of DFE-adjusted eye-scope BER measurements are generated by using BER-specific correction values to adjust the voltage offset values of the eye-scope BER measurements.

A loading unit includes a surgical buttress releasably secured to an anvil assembly and/or a staple cartridge secured thereto by at least one anchor, and a drive assembly including a knife blade, wherein movement of the drive assembly from a proximal position to a distal position results in the knife blade cutting the at least one anchor and freeing each surgical buttress from the anvil assembly and/or cartridge assembly.

Abstract: An inbound communication is received by a contact center. For example, the inbound communication may be a text-based communication. The inbound communication is classified based on feedback from one or more prior inbound communications. For example, the feedback may be based on whether a previous communication was transferred, was dropped, based on feedback provided by a contact center agent, based on feedback provided by a user, and/or the like. In response to classifying the first inbound communication, the inbound communication is routed differently in the contact center. For example, the inbound communication is routed to a different contact center queue based on the feedback of the previous communication.
