Abstract

Systems and methods for controlling a moving barrier responsive to a transmission by a barrier operator controller comprising a plurality of 4-bit output nibbles generated from a 32 bit rolling code. The bit positions of the rolling code are inverted, divided by 16, converted to four bit base 9 coefficients, each four bit base 9 coefficients is substituted with a corresponding 4-bit output nibble. Receipt of the plurality of 4-bit output nibbles causes a barrier operator to actuate a motor connected to the moving barrier.

Claims

1. An apparatus, comprising:

a portable controller for a door operator, comprising a processor, a first actuator operatively connected to the processor, and a transmitter operatively connected to the processor;

wherein the processor is configured to;

invert bit positions of a 32 bit rolling code,

divide the inverted code by 16,

convert the divided inverted code to four bit base 9 coefficients, and

substitute a 4-bit output nibble for each four bit base 9 coefficient in the divided converted code; and

wherein the transmitter is configured to transmit the substituted 4-bit output nibble responsive to actuation of the first actuator.

2. The apparatus of claim 1, wherein the portable controller further comprises a memory storing a lookup table of substitutions between each of a plurality of four bit base 9 coefficient values and a corresponding plurality of 4-bit output nibbles;

and

wherein the controller is configured to substitute the 4-bit output nibble in the divided converted code according to the lookup table.

3. The apparatus of claim 1, wherein the transmitter is further configured to transmit the substituted 4-bit output nibble to a receiver associated with a barrier operator, receipt of the substituted 4-bit output nibble causing the barrier operator to send a control signal to a motor associated with the barrier to cause the barrier to stop, move toward an open position, or move toward a closed position.

4. The apparatus of claim 1, wherein the portable controller further comprises a second actuator;

and

wherein the processor is further configured to enter into a standard programming mode, responsive to continuous actuation of the first actuator and simultaneous repeated actuation of the second actuator.

5. The apparatus of claim 4, wherein the portable controller further comprises a receiver configured to receive a code from another controller while the processor is in the standard programming mode.

6. The apparatus of claim 1, wherein the portable controller further comprises a receiver;

wherein the receiver is configured to receive a code from another controller; and

wherein the processor is further configured to derive the 32 bit rolling code from the code received from the other controller.

7. The apparatus of claim 1, wherein the portable controller further comprises a first LED operably connected to the processor and configured to illuminate responsive to actuation of the first actuator or a second actuator operably connected to the processor.

8. The apparatus of claim 6, wherein the first LED is configured to illuminate responsive to actuation of the first actuator;

and

wherein the portable controller further comprises a second LED operably connected to the processor and configured to illuminate responsive to actuation of the second actuator.

9. An apparatus, comprising:

a portable controller for a door operator, comprising;

a processor configured to process a rolling code expressed in 32 bits by;

inverting bit positions of the rolling code,

dividing the inverted code by 16,

a first actuator operatively connected to the processor;

an LED operatively connected to the processor and configured to illuminate as directed by the processor;

a transmit antenna;

a transmitter operatively connected to the processor with an inter-integrated circuit (i²c) bus, configured to transmit each substituted 4-bit output nibble, via the transmit antenna, responsive to actuation of the first actuator;

a receiver operatively connected to the processor with a serial peripheral interface (SPI) bus;

a receive antenna operatively connected to the receiver; and

a memory operatively connected to the processor.

10. The apparatus of claim 9, wherein the portable controller further comprises a second, third, and fourth actuator operably connected to the processor.

11. A method for controlling a moving barrier, comprising:

generating, by a processor of a barrier operator controller, a plurality of 4-bit output nibbles from a 32 bit rolling code by;

inverting bit positions of the rolling code,

dividing the inverted code by 16,

converting the divided inverted code to four bit base 9 coefficients, and

substituting each of a plurality of four bit base 9 coefficients in the divided converted code with a 4-bit output nibble; and

responsive to actuation of a first actuator of the barrier controller operator;

transmitting, by a transmitter of the barrier operator controller to a receiver of a barrier operator, the plurality of 4-bit output nibbles, receipt of the plurality of 4-bit output nibbles causing the barrier operator to actuate a motor connected to a moving barrier.

12. The method of claim 11, wherein generating the plurality of 4-bit output nibbles further comprises substituting each of the plurality of four bit base 9 coefficients with a 4-bit output nibble identified in a lookup table as corresponding to the four bit base 9 coefficient.

13. The method of claim 11, wherein receipt of the plurality of 4-bit output nibbles further causes the barrier operator to actuate the motor connected to the moving barrier to cause the moving barrier to stop, move toward an open position, or move toward a closed position.
