Abstract: This disclosure describes techniques for a configuration-monitoring service of a service provider network to provide users with the ability to access to configuration data across multiple accounts using a single account or other centralized access point. The configuration-monitoring service may allow users with multiple accounts registered with the service provider network to designate a central account (or “aggregator account”) through which the users can access and review configuration data across multiple accounts (or “source accounts”) and/or multiple regions (or “source regions”). After determining an aggregator account, the configuration-monitoring service may begin collecting configuration data from the source accounts and/or source regions, and transporting the configuration data to the aggregator region to be accessed using the aggregator account.

Abstract: A vaginal speculum and side wall retractor allows clinicians to visualize the cervix and upper vagina by retracting vaginal walls simultaneously. This device is comprised of a handle, a mobile introducer allowing the device to comfortably be inserted vaginally, and a lower blade capable of stabilizing the cervix and a body containing the side wall retractor. This retractor is comprised of a rolled-up sheet of transparent plastic which can be opened through a rotating shaft countersunk in the body of the base. A friction or sprocket gear allows the rotating shaft to open and close the plastic side wall retractor as well as completely unwinding the transparent plastic sheet so that the device can be removed while leaving surgical instruments in the vagina. The rotating shaft serves as a light guide and brings light from the knob, which contains an LED, into the rolled-up sheet during examinations.
