The backlight source may define a two-dimensional matrix of light sources configured to generate an initial light. The lenses may be mounted adjacent to the backlight source, aligned with the light sources, and configured to generate a collimated light. The passive diffuser may be mounted adjacent to the lenses and configured to spatially spread the collimated light. The active diffuser may be mounted adjacent to the passive diffuser, configured to generate an intermediate light in response to the collimated light, and configured to change a diffusive property of the intermediate light in response to a scattering signal. The transmissive display may be mounted adjacent to the active diffuser and configured to generate multiple visible images by modulating the intermediate light.

A system configured to synchronize the displays of multiple infusion pumps is provided. In some embodiments, the system includes a plurality of infusion pumps in communication with a server. An individual infusion pump synchronizes its internal clock by communicating with the server. Based on the synchronized internal clock, the infusion pump determines the current time, calculates a parameter based on the current time, and causes screen content corresponding to the calculated parameter to be displayed.

A mode-selectable backlight and privacy display employ directional scattering features to provide emitted light. The mode-selectable backlight includes a light guide, a first directional scattering feature to provide broad-angle emitted light from guided light having a first propagation direction within the light guide during a public mode, and a second directional scattering feature to provide directional emitted light from guided light having a second propagation direction within the light guide during a privacy mode. The directional emitted light the provided during the privacy mode is directed into a viewbox. The mode-selectable privacy display further includes light sources configured to provide the guided light having the first and second propagation directions along with an array of light valves configured to modulate the broad-angle emitted light as a public image and the directional emitted light as a private image visible within the viewbox.
