Abstract: An electrostatic discharge (ESD) circuit for use with motorized window shades includes an antenna connected to a motor controller having a printed circuit board, a receiver or transceiver, a microprocessor and memory that are connected to and operate a motor. The ESD circuit is connected to the line-in between the antenna and the downstream components of the printed circuit board. The ESD circuit includes an inductor in parallel with two anti-parallel diodes in reverse polarity to one another. The ESD circuit shunts damaging signals or ESD events to ground by providing a lower impedance or lower resistance path to ground for these signals, whereas the ESD circuit allows the signals of interest to pass by the ESD circuit as the ESD circuit provides a higher impedance or higher resistance path to ground as compared to the signal of interest passing through the receiver or transceiver of the motor controller.

Abstract: A motorized roller shade includes a shade tube, including an outer surface upon which a shade is attached, an inner surface defining an inner cavity and two end portions, a motor/controller unit, disposed within the shade tube inner cavity and mechanically coupled to the shade tube inner surface, including a support shaft configured to attach to a mounting bracket, and a DC motor having an output shaft coupled to the support shaft such that the output shaft and the support shaft do not rotate when the support shaft is attached to the mounting bracket. A wireless receiver is coupled to the motor/controller unit to receive wireless signals and an antenna is arranged on or in at least one of the two end portions.
