Abstract: A memory controller component of a memory system stores memory access requests within a transaction queue until serviced so that, over time, the transaction queue alternates between occupied and empty states. The memory controller transitions the memory system to a low power mode in response to detecting the transaction queue is has remained in the empty state for a predetermined time. In the transition to the low power mode, the memory controller disables oscillation of one or more timing signals required to time data signaling operations within synchronous communication circuits of one or more attached memory devices and also disables one or more power consuming circuits within the synchronous communication circuits of the one or more memory devices.

Abstract: An assembly with a shock inducing tool and shock sensitive components. The assembly includes a shock mitigator that is constructed in a manner that allows a communication line to stretch across an interface of the mitigator between a housing for the components and the shock inducing tool. So, for example, where the tool is a perforating gun, power and/or communication with the tool need not be sacrificed for in exchange for safeguarding electronic components of the housing with the mitigator.

Abstract: An electrical connector module is for completing an electrical connection in a wellbore device. The module has an outer surface having at least one groove that receives and frictionally retains an electrical wire in a circuitous path that relieves strain on the wire. An electrical connector is at least partially disposed in the at least one groove and is connected to the electrical wire.

Abstract: A shielded access apparatus for enabling personnel access to an enclosure which is shielded to prevent propagation of electromagnetic energy into and out of the enclosure. The apparatus includes an access enclosure of electrically conductive material and first and second openings in the enclosure. A shield is positioned in the enclosure between the first and second openings for preventing radiated electromagnetic energy passing through one of the openings from travelling along a straight line to the other opening. Absorption material lines the interior of the enclosure and absorbs radiated electromagnetic energy passing through the enclosure.

Abstract: A shielding enclosure for preventing propagation of electromagnetic radiation into or out of the enclosure comprising a support structure and a plurality of sheets of electrically conductive material supported thereon. Each of the sheets has an edge extending therearound and a region of overlap extending inwardly of and along the edge. The region is in overlapping engagement with the region of overlap of sheets adjacent thereto on the support structure so as to define a wave guide gap. Adjacent sheets are pressed together by pressure plates at the overlapping regions to maintain a gap width through which the electromagnetic radiation cannot propagate. Shielding components used to construct a shielding enclosure are also disclosed.
