A portable multi-event reminder device includes a battery-powered electrical
timer
circuit that is programmable with respect to selecting at least two overlapping
time periods, so as to generate prompts for at least two functionally related but
time-independent events. A solitary two-state switch is the sole input device employed
by a user to provide the desired timing programming. The timer circuit is configured
to generate a first electrical reminder signal upon expiration of the first selected
time period and to generate a second electrical reminder signal upon expiration
of the second selected time period. The reminder signals activate one or more sensory
alerts that generate human-perceivable alerts for prompting a user.
