METHOD AND APPARATUS FOR SUPPLYING ELECTRICITY TO A METER BY THE HELP OF A READING DEVICE |
摘要 |
Electronic circuits in a register associated with a commodity usage meter capture energy from a meter reading device when the device is coupled to the register (e.g., either electrically or inductively coupled) for the purpose of reading metered quantity data from the register. Electrical charge obtained from the reading device may be stored in a high-capacity storage capacitor. When the capacitor is sufficiently charged, it provides power to at least part of the register circuits, such as a controller, for at least the duration of the communication session with the reading device. In some embodiments, the capacitor may additionally supply sufficient power to operate the register until a subsequent reading device coupling. |
