Methods and systems for controlling an insulin pump in response to glucose measurements are responsive to a base insulin delivery profile and a temporary insulin delivery profile. These can be used, e.g., to control blood glucose level of a subject using a continuous glucose monitor and an insulin infusion pump. During a selected time range, an insulin amount for the pump to supply is determined using the temporary insulin delivery profile. Outside that time range, the insulin amount is determined using the base insulin delivery profile. The temporary insulin delivery profile can specify an exact amount to be supplied (a “hard” profile), a nominal amount to be supplied if doing so does not drive glucose out of a desired zone (“soft”), or a soft profile with a minimum amount of insulin to be delivered (“semi-soft”).

A multilayer reflector useable to reflect or transmit light over the visible wavelength range includes optically thick constituent layers. The optical thickness of the constituent layers through the thickness of the reflector defines a layer thickness profile.

The layers desirably have an optical thickness in a range from about one to five or one to ten design wavelengths. The reflector can be a polarizer, reflecting only one normally incident polarization state, or a mirror, reflecting two normally incident orthogonal polarization states.
