Abstract: 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.
