Illuminated time-passage indicator

A time-passage indicator, comprising:

• a housing comprising a base surface on one side and a second surface on the opposite side;
• a plurality of light elements located inside the housing;
• a window comprising an inner and an outer surface, wherein the window is attached to the second surface of the housing and diffuses or scatters the light from the plurality of light elements;
• and
• a processor that controls the plurality of light elements;
• wherein:
• the light elements emit light through the window to form an illuminated region viewable by a user;
• the processor controls the light elements such that the illuminated region changes to indicate the passage of time according to a timing mode that is selectable to be a fixed timing mode or a variable timing mode;
• and
• the illuminated region is viewable from all angles between 10 degrees and 90 degrees, where the angle 10 degrees is measured from a plane of the base surface, and the angle of 90 degrees corresponds to a normal viewing angle.

• the processor controls the light elements such that the illuminated region changes to indicate the passage of time;
• and
• the illuminated region is viewable from all angles between 10 degrees and 90 degrees, where the angle 10 degrees is measured from a plane of the base surface, and the angle of 90 degrees corresponds to a normal viewing angle.

A network of time-passage indicators, comprising two or more time-passage indicators, wherein:

• a first time-passage indicator in the network of time-passage indicators comprises:
• a housing comprising a base surface on one side and a second surface on the opposite side;
• a plurality of light elements located inside the housing;
• a window comprising an inner and an outer surface, wherein the window is attached to the second surface of the housing and diffuses or scatters the light from the plurality of light elements;
• a processor that controls the plurality of light elements;
• and
• wireless communication electronics;
• wherein:
• the light elements emit light through the window to form an illuminated region viewable by a user;
• the processor controls the light elements such that the illuminated region changes to indicate the passage of time;
• and
• the illuminated region is viewable from all angles between 10 degrees and 90 degrees, where the angle 10 degrees is measured from a plane of the base surface, and the angle of 90 degrees corresponds to a normal viewing angle;
• the processor of the first time-passage indicator communicates with a second time-passage indicator in the network of time-passage indicators using the wireless communication electronics;
• and
• a user input provided to the first time-passage indicator that causes a first timer parameter to be set in the first time-passage indicator also causes a second timer parameter to be set in the second time-passage indicator.
