Abstract: Clock domain phase adjustment techniques and systems for memory operations are described. In one example, a physical memory is communicatively coupled to a physical layer via a first clock domain and a memory controller is communicatively coupled to the physical layer via a second clock domain that is different than the first clock domain. A buffer is implemented in the physical layer. The buffer is configured to set a phase adjustment for a latency setting between the first and second clock domains. The phase adjustment is based on whether a mismatch has occurred in data output by the buffer to the memory controller based on a comparison to the latency setting.

Abstract: Methods, apparatus, devices, and systems for clamping hollow structures with multi-sectional composite clamps are provided. In one aspect, a method includes: sequentially clamping at least two clamp layers around the hollow structure by clamping a first clamp layer around the hollow structure by connecting one or more clamp sections of the first clamp layer to form at least one first joint and clamping a second clamp layer around the first clamp layer by connecting one or more clamp sections of the second clamp layer to form at least one second joint. The at least one second joint and the at least one first joint mismatch with each other around the hollow structure.

Abstract: A system for coupling pipes includes a first pipe having a tapered, spigot end; a second pipe having a tapered, spigot end; a coupler having two tapered socket ends adapted to internally receive the respective tapered, spigot ends of the first pipe and the second pipe; and a resistive element.
