Publication number: 20170254051Abstract: A monitoring system, hardware, and methods are provided for monitoring and detecting loosening and/or detaching of a component of a machine. The systems and methods employ a wireless sensor network platform including sensor nodes and sink nodes operating at an radio frequency (RF) that is about one order of magnitude lower than a standard WSN RF of 2.4 GHz. At least one sensor node comprising at least one sensor element is deployed in or on the component of the machine, or deployed in or on the machine at a point where the component is attached. The sensor node sends a signal to the sink node upon sensing loosening and/or detaching of the component, and the sink node generates an alarm. Embodiments provide real-time detection and localization of a detached machine component to facilitate fast retrieval of the component. Therefore, damage caused by the detached component reaching critical downstream components can be avoided.Type: ApplicationFiled: March 2, 2017Publication date: September 7, 2017Inventors: Hossam S. HASSANEIN, Abdallah Y. ALMA'AITAH, Khaled OBAIA

Publication number: 20170043376Abstract: A planar screen cloth for use in a screening device for screening out oversize objects in a material flowing in a direction includes a metal plate substructure having a perimeter and a plurality of longitudinal ligaments and transverse ligaments, forming a grid. A wear-resistant layer is applied to the entire screen cloth. Each transverse ligament comprises a leading edge and a trailing edge; and is angled such that the leading edge is disposed below the trailing edge. The transverse element thus is angled to face the direction of material flow.Type: ApplicationFiled: August 12, 2016Publication date: February 16, 2017Inventors: YEU (JOHN) TIEU, KHALED OBAIA, DANIEL MACNEIL, DAMIEN REID
