Implementing ICON into Leeds Maternity Services
Leeds Maternity Services introduced ICON to reduce Abusive Head Trauma triggered by crying in babies. The program involved training midwives, documenting discussions, and maintaining momentum through various strategies like display boards and targeted conversations.

CMM Comparison of Coil A115 and Reaction-Impregnation Filler and QXFA116 Fuji film Fred Nobrega August 8, 2019 Coil Working Group Meeting
Introduction QXFA115 CMM measurements indicate a bump on the coil about 0.09 mm above the coil outer surface that runs longitudinally about 2 m long and is about 5 turns wide on the transition side of the coil. A similar but smaller bump is on the coil about 0.05 mm above the coil outer surface that runs longitudinally about 3 m long and is about 5 turns wide on the non-transition side of the coil. It is difficult to see or feel by touch the bump on the coil that is evident on the CMM plots. The FNAL CMM plots are 2D cross sections looking from the return end of the coil to the lead end and are a best fit to the OD and midplane. The coil transition (T) side (layer jump) is on the right side of the plot and the non transition (NT) side is on the left side of the plots. The OD tolerance is 0.127 mm. Red arrows on the FNAL CMM plots are used when the measurement is greater than 0.127 mm on the CMM plot The CMM plots have additional information in a box with a leader line pointing to the surface the information pertains to.

Next Steps Epoxy Impregnate coil QXFA116 Use Fuji film on coil QXFA116 before removal from impregnation tooling. Use Fuji film on coil QXFA115 with impregnation tooling and compare results with QXFA116. Continue to investigate cause of bumps/ridges along coil O.D.
