Patent number: 8923523Abstract: The selective filtering earplugs allow a user to filter most external and environmental sounds, only allowing a set of pre-approved sounds to be heard by the user. The earplugs include a sound acquisition module and at least one filtering earplug. The sound acquisition module includes a microphone for receiving environmental sounds and a controller for converting the received environmental sounds to a digital signal. First memory is provided for storing the digital signal and second memory is provided for storing a database of pre-approved sound signals. The controller compares the digital signal with the database of pre-authorized sound signals. If the digital signal matches a pre-authorized sound signal of the database, then a transmitter transmits the digital signal. The filtering earplug includes a receiver for receiving the digital signal and a converter for converting the digital signal into an audio signal.Type: GrantFiled: December 11, 2012Date of Patent: December 30, 2014Assignee: King Fahd University of Petroleum and MineralsInventor: Abdelhafid Bouhraoua

Patent number: 8779893Abstract: The system for controlling vehicle ignition provides three separate levels of access to prevent unauthorized users from actuating ignition of a vehicle. The system includes a radio frequency identification tag having permanent computer readable memory and volatile computer readable memory associated therewith. The radio frequency identification tag is preferably embedded within a vehicle key. A predetermined permanently assigned authentication code is stored in the permanent computer readable memory and a variable time stamp is stored in the volatile computer readable memory. The permanently assigned authentication code and the variable time stamp are transmitted upon activation of the radio frequency identification tag. Vehicle ignition occurs only upon the mechanical operation of the key in a conventional ignition switch and matching of both the permanently assigned authentication code and the variable time stamp with codes and stamps stored in vehicle memory.Type: GrantFiled: September 12, 2011Date of Patent: July 15, 2014Assignee: King Fahd University of Petroleum and MineralsInventors: Muhammad Wasim Raed, Abdelhafid Bouhraoua

Patent number: 8776917Abstract: The stair-climbing apparatus has a series of articulating wheel sets extending below the platform. All of the wheel sets are vertically adjustable to negotiate stairways and similar changes of elevation. The lead wheel set is fixed longitudinally relative to the platform, while following wheel sets are longitudinally adjustable to adjust for the pitch or slope of different stairways. The apparatus uses sensors (e.g., mechanical, infrared, ultrasonic, etc.) to detect the presence of the stair risers and their height, control of the assembly being accomplished by a control circuit on board the machine. The wheel sets are raised and lowered independently of one another by pantograph mechanisms extending between the platform and the wheel sets. The horizontally adjustable wheel sets are positioned by a longitudinally disposed rack on the platform.Type: GrantFiled: August 27, 2013Date of Patent: July 15, 2014Assignee: King Fahd University of Petroleum and MineralsInventors: Abdelhafid Bouhraoua, Nesar Merah, Jaseem Al-Muaybid, Abduljabar Al Sayoud, Ayman Al-Darweesh, Jawad J.

Patent number: 8596134Abstract: The bolt tension monitoring system provides remote monitoring of the tension of a bolt, thus allowing for remote monitoring of general structural health and integrity of the fastener. The bolt tension monitoring system includes a housing adapted for being retained on a head of a bolt to be monitored. The system further includes a force transducer positioned between the head of the bolt and a surface in which the bolt is fastened and measures tension between the head of the bolt and the workpiece surface. A controller circuit within the housing calculates the difference between currently measured tension between the head of the bolt and the workpiece surface and an initially measured tension. A wireless transponder mounted in the housing transmits an alert signal if the calculated difference exceeds a pre-defined threshold value.Type: GrantFiled: September 21, 2011Date of Patent: December 3, 2013Assignees: King Fahd University of Petroleum and Minerals, King Abdulaziz City for Science and TechnologyInventors: Samir Mekid, Abdelhafid Bouhraoua

Patent number: 8544646Abstract: The medical safety box is a system using RFID (Radio Frequency Identification) technology to ensure that correct delivery of the correct treatment in the form of medication or injection to in-hospital patients is consistently carried out. The system includes a medical box containing whatever medication or injection that needs to be administered to a specific patient. The box has a locking mechanism that can only be opened by an RFID wristband, which is worn by that same specific patient, thus assuring that the medicine in the box is administered to the correct patient.Type: GrantFiled: June 6, 2011Date of Patent: October 1, 2013Assignee: King Fahd University of Petroleum and MineralsInventors: Abdelhafid Bouhraoua, Malick Ndiaye, Merah Farouk, Ahmad Hamoud Ahmad Dehwah, Saad Addin Almourad

Patent number: 8540468Abstract: The smart lid for smart bolts and probes is an electronic sensor for use with a smart bolt or probe having a color indicator for indicating tension. The smart lid includes a color sensor that provides electrical data corresponding to light received from the color indicator of the smart bolt or probe, a microcontroller that receives electrical data from the color sensor and converts that data to a digital form and compares the data against at least one limit, and provides a digital indication wirelessly to a remote monitor if the at least one limit has been exceeded. In this fashion a warning or emergency condition can be indicated when the tension experienced by the smart bolt is too low or too high. The smart lid may include an electrical power source that scavenges electrical power from ambient electromagnetic fields (EMF) and stores the electrical power in a battery.Type: GrantFiled: September 13, 2011Date of Patent: September 24, 2013Assignees: King Fahd University of Petroleum and Minerals, King Abdulaziz City for Science and TechnologyInventors: Samir Mekid, Abdelhafid Bouhraoua, Uthman Baroudi

Patent number: 8151025Abstract: The fast round robin circuit includes AND gates, OR gates, multiplexers and four D flip-flop gates configured to handle requests using linear propagation of a single grant token. In this manner the device avoids wasting clock cycles when some of the arbitrated entities do not have a pending request. The circuit has an R stage and an S stage. The R stage contains the request signal and an R memorization element to memorize the request. The S stage is the arbitration stage where the next active request is selected based on the position of the current request. The selection is then memorized in an S selection bit memorization element. There is one request signal and one pair of R and S Flip-Flops associated to every requesting entity. The selection circuit skips inactive requests to enable the next active request in a polling direction defined by the circuit.Type: GrantFiled: December 7, 2010Date of Patent: April 3, 2012Assignee: King Fahd University of Petroleum & MineralsInventor: Abdelhafid Bouhraoua
