Abstract

There is disclosed an in-line free-form sensor for controlling power flow to a utilization device. The in-line sensor is contained within a housing attached along a power cord and the housing contains no externally-visible moving parts. The sensor can be trained to respond to certain stimuli, such as light, sound, temperature, human presence, and/or motion. The sensor can control the power directly by operation of a switch or can provide signals for use by a device external to said housing.

1. A self-contained controller for use in controlling the flow of electricity from an electrical source to an electrical load, said controller comprising:

a housing for attaching to a free form power line, the power line not permanently attached to a structure such that said housing is free to move in conjunction with the power line, said housing adapted for attaching between said source and said electrical load and fitting around at least one wire of said power line at a point in said power line where said power line remains in free form even after said attachment;

said housing containing a switch for enabling and disabling the flow of electricity to said load, said switch operable in response to certain externally sensed criteria without contact by a user at the time said power is enabled or disabled.

2. The controller of claim 1 wherein said criteria is selected from the group consisting of:

pressure sensors, light sensors, time sensors, chemical sensors, temperature sensors, rate of rise sensors, smoke sensors, moisture sensors, presence sensors, and sound sensors.

3. The controller of claim 1 wherein said controller further includes:

contacts for cutting into said power line for obtaining power from said power lines for internal operation of said controller.

4. The controller of claim 1 wherein said criteria are established by inputs received from external sources.

5. The controller of claim 4 wherein said inputs are received from the group of at least one of the following:

pressure inputs, sound commands, RF signals, and power line signals, including impulse signals.

6. A device for controlling power delivery along a free form power cord, said device comprising:

a self-contained controller for attaching permanently along a free form portion of power cord and supported by said free form power cord at a point on said power cord where said power cord is in free form, said power cord remaining in free form after said attachment, said controller determining without human intervention that certain parameters have been met; and

operative under control of such determination for modifying said power delivery along said cord.

7. The device of claim 6 wherein said controller is enclosed within a housing, said housing having an outside area and an inside area where said controller resides, and wherein said parameters are entered into said controller without the use of mechanical devices on said outside surface of said housing.

8. The device of claim 6 wherein said controller is operative under control of the attainment of a certain time.

9. The device of claim 6 wherein said controller is operative under control of certain ambient light levels.

10. The device of claim 6 wherein said controller is operative by power obtained from said power cord.

11. The device of claim 6 wherein said controller is operative under control of the attainment of a certain time and further operative under control of the attainment of another time.

12. The device of claim 6 wherein said controller is operative under first control of certain ambient light levels and further operative under second control of the attainment of a time period subsequent to said first control.

13. The device of claim 8 wherein said controller further includes:

a clock and wherein said certain parameters are time settings selectively established with respect to said clock.

14. The device of claim 6 wherein said device is constructed as a pair of half shells mountable around said power cord.

15. The device of claim 14 further including means within said half shells for cutting into said power line.

16. The device of claim 6 wherein at least a portion of said controller is nano tech derived.

17. The device of claim 6 wherein said controller further includes a light sensor and wherein said certain parameters are ambient light settings.

18. The device of claim 6 wherein said power cord has a plug on the proximal end and a power outlet on the distal end, and wherein said device is positioned between said proximal and distal ends, such that said device is capable of obtaining operational power from said power cord when said plug is connected to a source of power and such that said device is capable of selectively delivering power to said power outlet.

19. The device of claim 6 wherein said determination is selected from at least one of the group consisting of:

pressure sensors, light sensors, time sensors, chemical sensors, temperature sensors, rate of rise sensors, smoke sensors, moisture sensors, pressure sensors, presence sensors, and sound sensors.

20. The device of claim 6 wherein said parameters are established by inputs received from external sources.

21. The device of claim 20 wherein said inputs are received from at least one of the group consisting of:

22. The method of adding automatic control of power along a free form power line;

said method comprising the steps of;

attaching a free form power switch to said power line between the proximal and distal ends of said power line outside of any supported housing, said power line remaining in free form after such attachment, said power switch operative to close and open under preestablished conditions independent of externally applied force at the time of opening and closing, and wherein said closed condition causes power to flow from said proximal end to said distal end and wherein said open condition causes said power flow to stop; and

establishing within said switch said preestablished conditions.

23. The method of claim 22 wherein said preestablished conditions are selectively programmable.

24. The method of claim 22 wherein said attaching step includes

cutting into said power line to both obtain power therefrom and to create a gap therein.
