Abstract: An operable fenestration operating system for a structure including a window or skylight having a frame, an operable sash and presenting a resistance force opposing opening and closing of the sash. A motorized operator is coupled with the frame and the sash to selectively open and close the sash. The invention includes an operator control unit communicatively connected to the motorized operator. The operator control unit includes a processor, a sensor for sensing the magnitude of the resistance force, a pulse width modulation circuit for supplying electrical power to the motorized operator. The processor varies the torque output of the motorized operator using the pulse width modulation circuit in response to the sensed parameter.

Abstract: A disposable window handle for use in installing a hinged window assembly. The handle includes a main body and a leg. The main body has a first end and a second end. The main body has an aperture formed therein proximate the first end. The aperture is adapted to receive a spindle on a window operator. The leg extends from the main body proximate the second end.

Abstract: A window fastener for controlling the locking and unlocking of a window is disclosed. The fastener provides an unlocking feature that is manually activated by the user and a locking feature that is automatically activated as the window is moved substantially proximate to the closed position. The unlocking feature disengages the fastener from the window and maintains disengagement so that further manipulation of the fastener is not required to facilitate window opening. The fastener also provides a positive confirmation feature that informs the user that the window is either closed and locked or open and unlocked.
