Abstract: An apparatus includes a display, a memory, and a processor. The memory stores events and available conversion options for a policy. The events include a conversion expiration event occurring on a conversion expiration date. Each conversion option is associated with a new policy type into which the policy is convertible prior to occurrence of the conversion expiration event. The processor presents a first page of a GUI, displaying a timeline of the events. The first page also displays a feature selectable to investigate the available conversion options. In response to receiving information associated with a selection of the feature, the processor presents a second page of the GUI, displaying the conversion options. The processor receives information associated with a selection of a first conversion option, and, in response, displays a graph illustrating the behavior of the policy upon conversion to the new policy type associated with the first conversion option.

Processing circuitry can be configured to generate an indication of a level of turbidity of a solution at or near a distal tip of a flexible scope, such as based on one or more signals from the one or more sensors. A control signal can be used to adjust an irrigation flow rate and/or a suction rate at the distal tip of the flexible scope. The level of turbidity can be determined using a sensor to measure electrolytic conductivity of the solution, a sensor to measure electromagnetic induction across a coil at the distal tip of the flexible scope and/or a measure of back reflected light or a measure of absorbed light emitted into the solution by a light source and measured by a light sensor.
