Patent ID: 7518325

Claim:
An anti-pinch powered window system, comprising: a window; a mechanical drive mechanism for raising and lowering the window; an electric motor for driving the mechanical drive mechanism responsive to a command to change direction of the window; a microcontroller unit for determining a normal load current level and a load current offset for use across an entire closing range of the window and generating the command responsive to a measured load current of the electric motor, wherein the command to change direction of the window is generated responsive to a determination that the measured load current has exceeded normal load level plus the load current offset, the load current offset determined based upon at least one of temperature, humidity or motor speed of the electric motor, the load current offset determined by the microcontroller unit from a plurality of load current offsets indexed according to the at least one of temperature, humidity or motor speed of the electric motor; and a memory for storing the plurality of load current offsets indexed according to at least one of temperature, humidity or motor speed of the electric motor.
