Everybody knows the feeling when you get home from work, you have to walk over to the mailbox and check to see if mail has been delivered. Not anymore.
On March 13, 2018, Week 11, Number 1448-2, the United States Patent and Trademark Office published U.S. Patent Number 9,913,555. The patent describes a mailbox detection means inside the mailbox to detect the presence of mail and a warning device that is operatively connected to the detection means to inform a user of the presence of mail in the mailbox.
Figure 1 describes that the detection unit for mailboxes comprises a mailbox; a detection means provided inside the mailbox to detect the presence of mail; and a warning device operatively connected to the said detection means to inform a user of the presence of mail in the said mailbox. One of the sensors appears to use a commonly used reed contact magnetic sensor.
