Abstract:
1. A device for indicating at least a first time interval and a second time interval, the device comprising: a plurality of lights, the plurality of lights including a first light illuminating during the first time interval and a second light illuminating during the second time interval, the second time interval following the first time interval; a keypad for providing inputs that a) select whether the device operates in a first device mode or a second device mode, b) establish a first mode total length of time when the device is in the first device mode, and c) establish a second mode duration for each of the at least first and second time intervals when the device is in the second device mode, the keypad including an incremental input and a decremental input that toggle the device between the first device mode and the second device mode, and an enter input that selects whether the device operates in the first device mode or the second device mode; an electronic display distinct from the plurality of lights and responsive to keypad inputs to prompt a user to select a) whether the device operates in the first device mode or the second device mode b) a first mode total length of time when the device operates in the first device mode, and c) the second mode duration for each of the at least first and second time intervals when the device operates in the second device mode; and a controller in communication with the keypad, the display, and the first and second lights, whereby the controller receives inputs from the keypad and produces outputs to the display, the controller controlling illumination of the first light during the first time interval, and controlling illumination of the second light during the second time interval, the controller also determining a) appropriate requests for user input depending upon whether the device is selected to operate in the first device mode or the second device mode, b) a first mode duration for each of the first and second time intervals by subdividing the first mode total length of time when the device is in the first device mode, and c) a second mode total length of time by summing the second mode durations of the at least first and second time intervals when the device is in the second device mode; wherein a user can determine whether the first or second time interval is pending by illumination of the first or second light.
