Method and apparatus to implement a \u201cvirtual\u201d real-time clock at a terminal based on time information from multiple communication systems. The first plurality TSA pairs are oriented at a non-zero angle about a first axis of the first support member and are oriented at a non-zero angle about a second axis of the first support member, with the second axis being perpendicular to the first axis. A programmable configuration register is configured to be programmed, in accordance with the communications protocol over the data transfer bus, to select two or more of the registers in the second configuration. matrix light source illuminates a bottle at an inspection machine. The second java bean is similar in format to the first java bean.
