Abstract: An alarm clock comprises circuitry for a primary alarm that causes an alarm to sound at a preset time of day and a secondary alarm which causes the alarm sound after countdown of a secondary alarm time period. The alarm clock includes a secondary alarm switch, a central processing unit and a memory electrically connected to the central processing unit and the secondary alarm switch. The memory contains a program which enables a user to set the alarm to activate at the end of the secondary alarm time period. The program preferably further provides that the secondary alarm period can also be set independent of whether the alarm has sounded at the primary alarm time or whether the primary alarm on/off switch is in an on or an off state. The program also preferably causes the secondary alarm time period to be displayed on the display unit.

Abstract: A timer device utilized both as an individual snooze-timer and in a conventional alarm clock having a snooze mode which allows for the selection of an uninterrupted snooze time period. The length of the snooze time period is selected by the user and is preferably up to 90 minutes. The individual snooze-timer device includes a housing having a display unit and a button-type switch, a central processing unit, a clock, and a memory. Preferably, the central processing unit, clock and memory are contained in a single microprocessor chip.
