چکیده
This proposal is a first pass at adding what is required in 08-015r3 for the phy and link layer state diagrams to include the low power transceiver options of partial and slumber modes for SAS. 1) The following are the proposed changes to the SP state machine. 6.8.1 SP state machine overview The SP state machine controls the phy reset sequence. This state machine consists of three four sets of states: a) OOB sequence (OOB) states; b) SAS speed negotiation (SAS) states.; and c) SATA host emulation (SATA) states; and d) SAS phy low power transceiver recovery (PM) states. This state machine consists of the following states ….. [In figure 154 – SP (phy layer) state machine-OOB sequences states: add a transition arrow from SP0:OOB_COMINIT to SP31:PM_Recovery_Start.]

Subject: Sas-1.1, Protocol for Changing Driver Amplitude
Introduction This proposal provides a method for SATA-capable SAS initiator or expander devices to handshake with SATA devices capable of both SATA and SAS transmission amplitudes such that the OOB sequence results in both devices operating at the optimum amplitude on an operation physical link. Also, this proposal addresses two additional issues. The first could occur when a SAS/SATA initiator...

Optical remote sensing systems operating on the principle of differential absorption have been employed since the mid-1970s for measuring airborne species. Multiwavelength sensing approaches, such as differential absorption lidar (DIAL) and differential absorption and scattering (DAS), are used for single (or a few) species detection boasting high sensitivity and long path detection capability....
