English term or phrase: an eight-cycle count | [0084] In some embodiments, the first trigger signal 762 may be a first voltage pulse, which indicates the beginning of a communication signal 761 and the second trigger signal 763 may be a second voltage pulse, which indicates the end of the communication signal 761. The number of cycles (e.g., two cycles are enclosed between the first and second trigger signal 762 and 763 of the communication signal 761) may correspond to the content of the communication signal 761. That is, the content of the communication signal 761 is a coded communication representing, for example, an instruction, data, an ID (e.g., an address) of an intended recipient, a control signal, status information, sensor data, or the like. For example, a two-cycle count (e.g., the first communication signal 761) may correspond to an instruction for powering on the drive motor 226 and an eight-cycle count (e.g., a second communication signal 764) may correspond to an instruction for powering off the driver motor. In some embodiments, a zero-cycle count may be established by transmitting a first trigger signal and a second trigger signal within a half-cycle, for example, at the falling edge zero-crossing 752 (FIG. 7A) and at the rising edge zero-crossing 753 (FIG. 7A). Furthermore, each of the coded communications may be predefined in the cart-computing devices 228 (FIG. 3) of the carts 104 (FIG. 3) and/or the master controller 106 (FIG. 3) so that the cart-computing device 228 (FIG. 3) and/or the master controller 106 (FIG. 3) may translate the number of cycles into the corresponding coded communication representing an instruction, data, an ID of an intended recipient, a control signal or the like. Я понимаю это следующим образом: Процессор осуществляет мониторинг и/или подсчет (регистрацию) количество циклов электрического сигнала переменного тока, которые прошли между первым и вторым триггерным сигналами, и, исходя из подсчитанного (зарегистрированного) количества циклов, выполняет какое-либо действие.
