| 摘要 |
A low power consumption wireless data transmission and control system 10 is disclosed and in one embodiment, is used to automatically articulate a shade 24 by use of a transmitted command signal 14. The system 10 contains a receiver/detector 18 which is selectively activated for only certain intervals of time thereby allowing substantially all of the previously transmitted signals 14 to be received while reducing the power consumed by the detector 18 during periods in which the signals 14 are absent.
