HOBOKEN - What could be the world's most persistent alarm clock is the product of a New Jersey man.

Engineer Paul Sammut has created a clock that can only be stopped by getting out of bed, going to another room and then punching the day's date into a keypad. No snooze button. If you unplug it, a battery takes over. No resetting the alarm.

The 25-year-old Hoboken resident says he started working on the Ramos Clock because it was hard for him to get up and get to work on time after college.

A friend suggested he try selling the clocks. Sammut has formed a company and already has more than 400 orders for the Ramos, which sells for between $200 and $800.
