Patents by Inventor Macram Bishai

Macram Bishai has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Electro-mechanical actuator
    Patent number: 7140151
    Abstract: An electro-mechanical actuator for a window lift mechanism including a plurality of motors for driving an output shaft. The actuator may be incorporated into a window lift mechanism including a dual rack and pinion assembly, for driving the pinions along the racks. According to another aspect of the invention there is provided a variety of anti-back-drive mechanisms, e.g. clutches. A clutch according to one embodiment includes locking pawls that resist back-drive. In another embodiment, locking cams rotate relative to a carrier to resist back-drive. An actuator consistent with the invention may incorporate an impact mechanism including a flexible carrier. The carrier flexes to prevent impact forces at an output gear train from coupling to an input gear train.
