Patent number: 11781105Abstract: A system for quickly determining antibiotic sensitivity of a microorganism comprising a triangular-shaped plate and cover for culturing, recovering, and re-suspending recovered microbial colonies and a second triangular-shaped plate comprising a non-liquid medium cut with concentric trenches over which the re-suspended microbial colonies are distributed by centrifugation and contacted with antimicrobial strips or disks.Type: GrantFiled: June 5, 2020Date of Patent: October 10, 2023Assignees: National Guard Health Affairs, King Saud bin Abdulaziz University for Health Sciences, King Abdullah International Medical Research CenterInventor: Ahmad Mohammed Shikan Aljefri

Patent number: 11534092Abstract: A blood collection tube for physically separating the plasma and red blood cell fractions of a centrifuged sample is described. The blood collection tube has an elastomeric sleeve with rigid tube segments at both ends. Following blood collection and centrifugation, the elastomeric sleeve may be twisted to constrict its inner diameter and physically separate the two fractions. The blood collection tube may be secured in this position with a pin and a clamp, and further with an adhesive tape with pH paper. This enables blood samples to be transferred over long distances to a central lab facility without spoiling.Type: GrantFiled: March 26, 2019Date of Patent: December 27, 2022Assignees: National Guard Health Affairs, King Saud bin Abdulaziz University for Health Sciences, King Abdullah International Medical Research CenterInventor: Ahmad Mohammed Shikan Aljefri

Patent number: 9253785Abstract: Embodiments enable cooperative transmissions from a group of cells (can include the serving cell and one or more neighboring cells) to a user equipment (UE). The cooperative transmissions emulate Hybrid Automatic Repeat Request (HARQ) transmissions to the UE. Specifically, when the UE is experiencing high interference, the UE's serving cell can create a transmit incremental redundancy (IR) group for the UE, which is used to transmit information in a HARQ-like fashion to the UE. Because interference is reduced, the UE can decode the information at a lower coding rate and higher coding gain.Type: GrantFiled: May 3, 2013Date of Patent: February 2, 2016Assignee: Broadcom CorporationInventors: Louay Jalloul, Djordje Tujkovic, Ahmad Mohammed

Patent number: 9143364Abstract: The present disclosure is described in the exemplary context of a Long Term Evolution (LTE) cellular network and is directed to a method and apparatus for estimating a gain and phase imbalance between an in-phase path and a quadrature path of a receiver operating in such a network. The method and apparatus specifically exploit channel coherence in time and frequency, and the properties of the Primary Synchronization Signal (PSS), and/or the Secondary Synchronization Signal (SSS), and/or information in the Physical Broadcast Channel (PBCH), all of which are defined by the LTE standard, to estimate the gain and phase imbalance of the receiver while it remains connected to a base station to receive data.Type: GrantFiled: October 10, 2013Date of Patent: September 22, 2015Assignee: Broadcom CorporationInventors: Ahmad Mohammed, Louay Jalloul
