Abstract

Ternary data as corresponds to a movable barrier operator is provided (21) and converted (22) into corresponding binary information. In a preferred approach this comprises converting each ternary trit into a corresponding binary pair. Pursuant to a preferred approach binary bits as correspond to, for example, fixed and/or non-fixed information (32 and 33) are provided (31) and then converted (34) into the aforementioned ternary data.

Claims

1. A method comprising:

providing ternary data as corresponds to a movable barrier operator;

converting the ternary data to a binary format to provide binary information;

transmitting the binary information between the movable barrier operator and a peripheral device.

2. A method of facilitating a communication as between a movable barrier operator and a peripheral device, comprising:

providing data to be transmitted, wherein the data comprises, at least in part, ternary data;

encrypting the data, at least in part, by converting at least some of the ternary data into corresponding binary data;

transmitting the corresponding binary data between the movable barrier operator and the peripheral device.

3. An apparatus comprising at least one of a movable barrier operator and a device that communicates with a movable barrier operator, comprising:

a first memory having ternary data to be transmitted as between the movable barrier operator and the device that communicates with a movable barrier operator;

a ternary-to-binary converter being operably coupled to the first memory and having a binary data output;

a transmitter operably coupled to the binary data output configured and arranged to externally transmit a binary-formatted version of the ternary data to one of the movable barrier operator and the device that communicates with the movable barrier operator.
