    摘要: Radio frequency identification (RFID) tags are associated with sensors. Sensor data from a sensor is internally associated with a mask address, such as that of a memory. The tags receive commands by a reader, which can include selection commands. The selection commands can be for selecting according to the sensor data, by invoking the mask address. The selection commands can be further associated with a mask value, calling for setting a selection flag only by those tags whose sensor data meets a selection condition relative to the mask value. Therefore the reader can select a sub-population of tags from a larger population based on sensor data.

    摘要: A D.C. lamp system having a number of small zener diodes arranged in eleccal parallelism with various lamp current supply wires. The zener diodes are sized so that the collective wattage ratings of the zeners is equal to the arithmetical product of the D.C. supply voltage and the summation of the safe amperages of the lamps in the system. In event of normal lamp burnout, any tendency of the other lamps to also burn out due to excessive current surge is countered by the action of the zener diodes; potential excess current is drained through the zener diodes to ground. A large number of small zener diodes are used in preference to one large zener diode, thereby minimizing the need for heat sinks or special cooling means required by a larger zener diode.
