Patent Application (from 2012): "Devices and Implements for Deterring Monsters, Specters, Demons, and the Like"

This patent application, filed in 2012, is called "Devices and implements for deterring monsters, specters, demons, and the like".

Here is a choice excerpt: Devices and implements for staving off monsters, specters, demons and the like as imagined by a child at bedtime. A hand-held controller unit is provided having a user interface, which is capable of being used by the child under the bed covers of a bed. The hand-held controller unit may include any of a walkie-talkie capability, a flashlight capability, a nightlight capability, the capability to activate an external device, and other capabilities. At least one external device may be provided which is capable of being placed beneath the bed and is configured to be activated by the hand-held controller unit. At least one substantially hollow air-through member may be provided which is configured to facilitate airflow between underneath the bed covers of the bed and above the bed covers of the bed. A supplemental bed cover may be provided that is configured to be placed on the bed.

Personally, I am most afraid of "the like".

Also, the Google Patent listing says the patent was granted.
