초록 ▼

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.

대표청구항 ▼

A method for use in combination with a window shade controller having a signal receiver adapted to allow a window shade to be positioned in a desired manner, said method adapted to reduce the electrical power consumed by said signal receiver, said method comprising the steps of: activating said signal receiver for a first predetermined period of time; determining if a portion of a signal has been received by said signal receiver during said first predetermined period of time; allowing said signal receiver to remain activated for a second predetermined period of time only if said portion of signal has been received by said signal receiver during said first predetermined period of time, thereby reducing the consumption of power by said signal receiver during a time in which said signal is not present. A method for reducing electrical power consumed by a receiver of data packets, each of said packets being formed by several sequentially timed signals, wherein the time between any two adjacent timed signals is made to assume only one of two possible values, and wherein said packet is made to have a total transmission time which is made to vary between a maximum and a minimum value, said method comprising the steps of: preventing substantially all electrical power from being input into said receiver for a first predetermined period of time, said first predetermined period of time being less than said minimum value; applying electrical power to said receiver for a second predetermined period of time, said second predetermined period of time being slightly greater than the larger value of said two possible values; determining if a first one of said sequentially timed signals has been received by said receiver during said second predetermined period of time; continuing to apply said electrical power to said receiver for a third predetermined period of time only if said first one of said sequentially timed signals has been received by said receiver during said second predetermined period of time; determining if a second one of said sequentially timed signals has been received by said receiver during said third predetermined period of time; determining a first amount of time elapsing between the receipt of said first and said second timed signals; comparing said first amount of elapsed time with each of said two possible values; continuing to apply said electrical power to said receiver for a fourth predetermined period of time only if said second one of said sequentially timed signals had been received by said receiver during said third predetermined period of time and only if said first amount of elapsed time was substantially equal to one of said two possible values; determining if a third one of said sequentially timed signals has been received by said receiver during said fourth predetermined period of time; determining a second amount of time elapsing between the receipt of said second and said third timed signals; comparing said second amount of elapsed time with each of said two possible values; continuing to apply said electrical power to said receiver for a fifth predetermined period of time only if said third one of said sequentially timed signals has been received by said receiver during said fourth predetermined period of time and only if said second amount of elapsed time was substantially equal to one of said two possible values, thereby allowing said receiver to receive at least one packet of data while reducing the amount of power consumed by said receiver when said at least one packet of data has not been received.
