Touch hem bar control
First Claim
1. A motorized shade for covering a window, a door, or a wall opening, the motorized shade comprising:
- a shade material extending from a top end to a bottom end;
a hem bar assembly connected to the bottom end of the shade material and comprising;
a touch sensing module comprising an RC oscillator; and
a longitudinal bar electrically coupled to the RC oscillator of the touch sensing module via a contact;
wherein the touch sensing module is adapted to detect a touch of the longitudinal bar of the hem bar assembly when the frequency of the RC oscillator is decreased below a predetermined threshold value and transmit a control signal in response to the detected touch; and
a shade drive unit operably connected to the top end of the shade material and comprising a motor and a motor control module adapted to receive the control signal and control the motor to open or close the shade material.

Abstract
A motorized shade for covering a window, a door, or a wall opening is provided that can be actuated by touching its hem bar. The motorized shade, such as a roller shade, comprises a shade material extending from a top end to a bottom end, a hem bar assembly connected to the bottom end of the shade material, and a shade drive unit operably connected to the top end of the shade material. The hem bar assembly comprises a touch sensing module adapted to detect a user touching the hem bar assembly and transmit a control signal in response to the detected touch. The shade drive unit comprises a motor and a motor control module adapted to receive the control signal and control the motor to open or close the shade material. The control signal can be wirelessly transmitted from the touch sensing module to the motor control module.
