    We describe the cryogenic half-wave plate rotation mechanisms built for and used in SPIDER., a polarization-sensitive balloon-borne telescope array that observed the cosmic microwave background at 95 GHz and 150 GHz during a stratospheric balloon flight from Antarctica in January 2015. The mechanisms operate at liquid helium temperature in flight. A three-point contact design keeps the mechanical bearings relatively small but allows for a large (305 mm) diameter clear aperture. A worm gear driven by a cryogenic stepper motor allows for precise positioning and prevents undesired rotation when the motors are depowered. A custom-built optical encoder system monitors the bearing angle to an absolute accuracy of +/-0.1 degrees. The system performed well in SPIDER. during its successful 16 day flight.

  • Missing Consent Forms in the Preoperative Area A Single-Center Assessment of the Scope of the Problem and Its Downstream Effects

    Garonzik-Wang, Jacqueline M.   Brat, Gabriel   Salazar, Jose H.   Dhanasopon, Andrew   Lin, Anthony   Akinkuotu, Adesola   O'Daly, Andres   Elder, Benjamin   Olino, Kelly   Burns, William   Camp, Melissa   Lipsett, Pamela A.   Freischlag, Julie A.   Haut, Elliott R.  

    Missing consent forms at surgery can lead to delays in patient care, provider frustration, and patient anxiety. We sought to assess the scope and magnitude of this problem at our institution. We surveyed key informants to determine the frequency and effect of missing consent forms. We found that 66% of patients were missing signed consent forms at surgery and that this caused a delay for 14% of operative cases. In many instances, the missing consent forms interfered with team rounds and resident educational activities. In addition, residents spent less time obtaining consent and were often uncomfortable obtaining consent for major procedures. Finally, 40% of faculty felt dissatisfied with resident consent forms, and more than two-thirds felt patients were uncomfortable with being asked for consent by residents. At our center, missing consent forms led to delayed cases, burdensome and inadequate consent by residents, and extra work for nursing staff.
