    摘要： In one embodiment, the present invention is an algorithm implemented in a microprocessor-controlled system which, for example, is disposed within an energy meter housing. Particularly, the microprocessor is coupled to a communications interface which receives and transmits messages on a power line or some other external communications media. Upon receipt of a message, the commands contained in the message are read. If a command corresponds to a "buffer and lock" command, then a timer operated by the microprocessor starts to run. For example, if data to be retrieved from the system is data which is erased from system memory when read therefrom, just prior to reading such data, a buffer and lock command is transmitted by the external communication device. Upon receipt of such command, the microprocessor initiates running of a timer and the data is read from the meter. The data also is copied to a buffer, e.g., a RAM memory location. If the data is "lost" during transmission, and as long as the timer is running, the data can be copied from the designated buffer and re-transmitted. In this manner, data normally not saved in a meter subsequent to a read operation is saved and, if necessary, re-transmitted.

    摘要： A motorized vehicle capable of fault detection and of operation after a fault has been detected. The vehicle has a plurality of control components coupled to a motorized drive and a comparator for comparing the output of each of the control components with outputs of other control components so that failures may be identified. The vehicle may have multiple processors coupled to a plurality of control channels by means of a bus and a decision arrangement that suppresses the output of any processor for which a failure has been identified.

    摘要： The apparatus for automatic return from test mode includes a switch or optical port on a meter bezel for initiating, upon user actuation, the storing of customer billing data in a meter register and converting the meter from a customer billing data recording and displaying mode of operation to a test mode of operation for performing one or more field test functions. In addition, to eliminate the likelihood that a customer will be under-billed for unrecorded energy consumption, the meter includes a timer for computing an elapsed period of time (which is programmable in length). Upon the expiration of a predetermined elapsed time, the meter is automatically returned to a customer billing mode of operation, regardless of the state of any test being performed during the test mode. Thus, the possibility that the customer will be under-billed for energy consumed while the meter is accidently left in the test mode is eliminated.
