Asymmetric stem drive gifford-mcmahon (gm) cryocooler

Patent published on the 2026-10-15 in US under Ref US20260318569 by SUMITOMO SHI CRYOGENICS OF AMERICA INC [US] (Dunn Stephen B [us])

Abstract: [0000] The efficiency of a GM expander having a stem drive and a rotary valve is improved by having ports in the valve, to the drive stem and displacer, that open fully when gas flows out at low pressure but can be partially restricted when gas flows in at high pressure. The rotary valve may be a disc type or spool type. Other types are also possible. Restricting the high-pressure flow to the drive stem reduces the speed of the expander as low-pressure gas flows out through the regenerator, thus[...]


Our summary: The Gifford-McMahon cryocooler utilizes an asymmetric stem drive with a rotary valve to enhance efficiency. Ports in the valve allow for optimal gas flow management under varying pressure conditions. This design reduces pressure drops during operation, improving overall performance.

OPMs for studying the developing brain

Published on 2026-10-01 by @MIT

Abstract: AbstractTremendous maturation in brain structure and function, underlying very rapid cognitive development, occurs in the early years of life, yet it has been difficult to obtain reliable measures of brain function over this period. A major challenge has been the difficulty of acquiring reliable neuroimaging data from awake young children, who often struggle to tolerate conventional imaging environments or remain still during scanning. Existing approaches each involves important compromises betw[...]


Our summary: OPMs enhance neuroimaging for studying the developing brain in young children. They provide high spatial and temporal resolution while being movement-tolerant. OPMs promise to improve research inclusivity for underrepresented clinical populations.
