Patent number: 11495858Abstract: A photovoltaic (PV) cell health monitoring apparatus includes a Radio Frequency Identification (RFID) tag mounted to the PV cell and having identifying information of the PV cell, and a sensor in communication with the RFID tag for measuring health information of the PV cell. The RFID tag stores the measured health information together with time and locality information of the PV cell and responds to an interrogation signal by transmitting the stored information together with the identifying information. A dust sensor in the form of a comb-like electrode array measures electrical capacitance as an indication of an amount of dust on an exposed surface of the PV cell. An RFID tag antenna arranged as a meander-line patch antenna covered with polyethylene has a dual function as a temperature sensor.Type: GrantFiled: February 24, 2020Date of Patent: November 8, 2022Assignees: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALS, MASSACHUSETTS INSTITUTE OF TECHNOLOGYInventors: Muhammad A. Hawwa, Hussain M. Al-Qahtani, M. Wasim Raad, David E. Hardt

Patent number: 9188502Abstract: The pipeline leak detector travels through a pipeline passively due to the flow of liquid through the pipeline. The device includes leading and trailing rings shaped to produce hydrodynamic resistance in order for the device to be carried through the pipeline. Wheels are provided about each ring, with at least one wheel having an odometer to measure distance traveled through the pipe. The rings are joined by a plurality of axially oriented connecting rods. A plurality of sensing elements extend between the rings. Each sensing element has a thin laminate of a piezoelectric film sandwiched between two electrically conductive layers, with an electrically insulating coating on the outside of each conductive layer. One of the rings includes microelectronic circuitry for data acquisition and storage.Type: GrantFiled: July 23, 2012Date of Patent: November 17, 2015Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Muhammad A.

Patent number: 8539820Abstract: The acoustic leak detection system with environmental noise isolation provides for the acoustic detection of leaks in a pipe while minimizing interference from external or environmental noise. The acoustic leak detection system includes a hollow shell adapted for positioning about the pipe to be inspected. A pair of gaskets are circumferentially secured to the inner surface of the hollow shell so that the pair of gaskets bear against the outer surface of the pipe to form an acoustically isolated region defined between the pipe, the pair of gaskets and the inner surface of the hollow shell. An acoustic sensor, microphone or the like is mounted on the hollow shell within the acoustically isolated region for detecting any acoustic signals; i.e., the sound produced by a leak in the pipe within the acoustically isolated region. Upon detection of a leak, an alert signal is generated.Type: GrantFiled: November 1, 2010Date of Patent: September 24, 2013Assignee: King Fahd University of Petroleum and MineralsInventors: Hussain M.
