Patent number: 11919843Abstract: Novel organoselenium selective ligands are presented and designed to determine metal ions in a sample. These ligands are used as complexing agents in a dispersive liquid-liquid microextraction procedure of copper and zinc ions. The procedure has a shortened extraction time, minimal organic solvent types, and lower amounts of solvents, as well as easy operation and high enrichment efficiency.Type: GrantFiled: February 23, 2023Date of Patent: March 5, 2024Assignee: KING FAISAL UNIVERSITYInventors: Hany Mohamed Abd El-Lateef Ahmed, Saadeldin Elsayed Ibrahim Shabaan, Mai Mostafa Khalaf Ali, Mohamed Gouda, Wael I.

Publication number: 20230043779Abstract: A method according to some embodiments include reporting, by a beamformee, an encryption capability indicator to a beamformer, wherein the encryption capability indicator is indicative of a capability of the beamformee to encrypt a feedback frame. The method may also include receiving, by the beamformee from the beamformer, an announcement frame in response to the beamformer receiving an indication that the beamformee is capable of encrypting the feedback frame, and then sending, by the beamformee, an encrypted feedback frame.Type: ApplicationFiled: January 21, 2022Publication date: February 9, 2023Inventors: Pavankumar Veerashetty, Wook Bong Lee, Ashok Ranganath, Ravi Gidvani, Shailender Karmuchi, Srinivas Kandala, Ruchen Duan, Mostafa Ibrahim

Patent number: 10275819Abstract: Incompatible item pairings may be eliminated or at least reduced when multiple items are presented. A pairwise approach is taken to train a machine learning model to return an incompatibility score for any given pair of items, which indicates a degree of incompatibility between the pair of items. Once trained, the machine learning model may be used to determine an incompatibility score for each unique pairing of items in a set of multiple items. In some embodiments, a graph is generated having nodes that correspond to the multiple items and undirected edges between pairs of the nodes. Scores are generated for each edge of the graph, a minimum spanning tree in the graph is determined, and the items are ranked based at least in part on the minimum spanning tree so that the items can be presented according to the ranking.Type: GrantFiled: May 13, 2015Date of Patent: April 30, 2019Assignee: Amazon Technologies, Inc.Inventors: Joseph Edwin Johnson, Mohamed Mostafa Ibrahim Elshenawy, Shiblee Imtiaz Hasan, Nathan Eugene Masters, JaeHa Oh, Benjamin Schwartz

Patent number: 9891643Abstract: A method to adjust the load transient regulation of a low drop-out (LDO)/load switch linear voltage regulator (LVR) with an n-type pass element having an open loop transfer function, including determining during a load transient event if the gate of the pass—element goes lower than a scaled value of the output voltage or a constant voltage level, generating a control signal that controls a current sink block if the gate voltage of the pass element is lower than the output voltage, and enabling a current sink block that is controlled by the control signal and connecting the output of the current sink block to the output of the LVR.Type: GrantFiled: December 4, 2015Date of Patent: February 13, 2018Assignee: Vidatronic, Inc.Inventors: Mohamed Ahmed Mohamed El-Nozahi, Faisal Abdellatif Elseddeek Ali Hussien, Mohamed Mostafa Saber Aboudina, Sameh Ahmed Assem Mostafa Ibrahim, Moises Emanuel Robinson

Publication number: 20170262537Abstract: Disclosed are various embodiments for initiating playback of audio scripts that correspond to content such as books or songs. Verbal content can be captured via a microphone. The text of the verbal content can be assessed to determine whether an audio script specifies a sound effect that should be played at particular cue words within the content. The verbal content is assessed to determine whether a user reading aloud or singing a song has reached a cue word. When a cue word is reached, the sound effect can be played.Type: ApplicationFiled: March 14, 2016Publication date: September 14, 2017Inventors: Samuel David Harrison, Mohamed Mostafa Ibrahim Elshenawy, Joseph Bradford Saunders, Benjamin Schwartz

Publication number: 20160218613Abstract: Inrush current is a critical, undesirable behavior that results from the uncontrolled start-up or shut-down of voltage regulators. Large inrush currents lead to voltage overshoot at the output node of voltage regulators and this can damage the regulator load, in addition to peak current that can damage the packaging or the regulator itself. Embodiments of the invention introduce methods of inrush current reduction based on voltage reference generation. For example, one method is based on multiple filtered steps of the voltage reference for the voltage regulator. For example, another method is based on creating a voltage reference signal that has a continuous slope starting from zero and ending at zero. Embodiments of the invention reduce or limit the inrush current for sensitive applications.Type: ApplicationFiled: January 26, 2016Publication date: July 28, 2016Applicant: Vidatronic, Inc.Inventors: Faisal Hussien, Sameh Ahmed Assem Mostafa Ibrahim, Mohamed Mostafa Saber Aboudina, Mohamed Ahmed Mohamed El-Nozahi, Moises Emanuel Robinson

Publication number: 20150190173Abstract: An endoscopic surgical apparatus and endoscopic surgery methods comprise an anchoring means for anchoring a living tissue, and a piercing means for piercing the living tissue, each means being driven by an independent driving means. The anchoring means and the piercing means are able to move along parallel axes that extend outside a distal end of a catheter, allowing piercing a living tissue on a short length without having to fold the living tissue.Type: ApplicationFiled: June 14, 2013Publication date: July 9, 2015Applicant: Endo Tools Therapeutics S.A.Inventors: Martin Hiernaux, Alexandre Chau, Vincent Huberty, Mostafa Ibrahim, Jacques Deviere
