Infrared sensor unit for controlling operation of electrically powered appliances
First Claim
1. A sensor unit for deactivating an electrical appliance when left unattended by a user, the sensor unit comprising:
- a passive infrared sensor for sensing the user through a field of infrared light provided within a viewable distance of the electrical appliance;
an adjustable timer in electrical communication with the passive infrared sensor for counting toward a predetermined amount of time when the user is not sensed within the field of infrared light;
a controller device being in electrical communication with the adjustable timer and the electrical appliance, the controller being operative to deactivate the electrical appliance upon the adjustable timer reaching the predetermined amount of time; and
a voice command module being operative to receive a command from the user, the voice command module being in communication with the electrical appliance to transmit the command to the electrical appliance, the electrical appliance performing a given operation in response to the command, the given operation including deactivation of the appliance the given operation being performed independently of the adjustable timer.

23. An infrared sensor unit for controlling an operation of an electrical appliance by a user, the sensor unit comprising:
-
a passive infrared sensor for sensing the user through a field of infrared light provided within a viewable distance of the electrical appliance;
an aperture device disposed on the passive infrared sensor, the aperture device being operative to close the passive infrared sensor from heat generated from the body temperature of the user;
an adjustable timer in electrical communication with the passive infrared sensor for counting toward a predetermined amount of time when the user is not sensed within the field of infrared light;
a controller device being in electrical communication with the adjustable timer and in wireless communication with the electrical appliance, the controller being operative to deactivate the electrical appliance upon the adjustable timer reaching the predetermined amount of time; and
a voice command module being operative to receive a command from the user, the voice command module being in communication with the electrical appliance to transmit the command to the electrical appliance, the electrical appliance performing a given operation in response to the command, the given operation including deactivation of the appliance, the given operation being performed independently of the adjustable timer.
