Abstract

The user may perform a smoke detector battery capacity test via an infrared (IR) trigger from a remote controller. When the proper amount of directed infrared energy (sourced by an infrared remote control device) is detected at the smoke detector the smoke detector runs the battery life test. The result of the battery test is displayed on a visual indicator on the smoke detector unit.

Claims

1. A method for indicating the remaining battery life of a smoke detector battery comprising:

any standard Television, DVD, VCR, Satellite, or Stereo Remote Controller which is able to transmit an Infrared (IR) signal by pressing a remote control button;

a remote IR photo diode receiver for detecting directed IR signals;

an IR sensitivity attenuation unit in the form of a lens and tube for the IR light to pass;

a Control Unit which will initiate a smoke detector battery capacity when receiving appropriate amount of IR energy,

a Control Unit which decodes battery test results and outputs information to a Visual Indicator.

2. The method for displaying the capacity of a smoke detector battery as claimed in claim 1, wherein the Control Unit determines the amount of battery life and outputs the information to an LED Visual Indicator as blinking at variable rates in the range of zero hertz to 4 hertz.

3. The method for displaying the capacity of a smoke detector battery as claimed in claim 1, wherein the Control Unit determines the amount of battery life and outputs the information to a numeric LED Visual Indicator or numeric LCD Visual Indicator.

4. The method for displaying the capacity of a smoke detector battery as claimed in claim 1, wherein the Control Unit determines the amount of battery life and outputs the information to an LED Visual Indicator as a blinking a variable number of times to indicate the remaining battery life.

5. The method for an audio transmission of the capacity of a smoke detector battery as claimed in claim 1, wherein the Control Unit determines the amount of battery life and outputs the information via a forced audio chirp as chirping a variable number of times to indicate the remaining battery life.

6. The method for triggering the battery life test as claimed in claim 1, where the triggering event is from an infrared remote control.

7. The method for receiving the IR signal as claimed in claim 1, wherein the IR energy from a remote is sufficient from the remote control key pressed to trigger the battery test regardless of the IR encoding.

8. The method for receiving the IR signal as claimed in claim 1, wherein the IR energy from sources of sunlight, incandescent light, florescent light, and LED lighting is filtered out.

9. The method for sensing the battery life as claimed in claim 1, wherein the Control Unit has stored the information of a number of previous battery tests to determine if the battery charge is deteriorating.

10. The method for sensing the battery life as claimed in claim 1, wherein the Battery Test Unit has the ability to place a light resistive load on the battery under test when taking the battery voltage measurement.

11. A system including an apparatus wherein the IR sensitivity attenuation is in the form of a small lens and tube for the infrared light to travel through.

12. A system using a blinking LED to issue a system state by either blinking the LED at a rate faster than 1 Hz (up to 4 Hz) or slower than 1 Hz (down to 0.25 Hz).
