Patent number: 11065616Abstract: Microfluidics has advanced in terms of designs and structures, however, fabrication methods are either time consuming or expensive to produce, in terms of the facilities and equipment needed. A fast and economically viable method is provided to allow, for example, research groups to have access to microfluidic fabrication. Unlike most fabrication methods, a method is provided to fabricate a microfluidic device in one step. In an embodiment, a resolution of 50 micrometers was achieved by using maskless high-resolution digital light projection (MDLP). Bonding and channel fabrication of complex or simple structures can be rapidly incorporated to fabricate the microfluidic devices.Type: GrantFiled: November 22, 2016Date of Patent: July 20, 2021Assignee: KING ABDULLAH UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Ulrich Buttner, Yousof Mashraei, Sumeyra Agambayev, Khaled N.

Patent number: 9747413Abstract: Disclosed are various embodiments for adaptive processing for sequence alignment. In one embodiment, among others, a method includes obtaining a query sequence and a plurality of database sequences. A first portion of the plurality of database sequences is distributed to a central processing unit (CPU) and a second portion of the plurality of database sequences is distributed to a graphical processing unit (GPU) based upon a predetermined splitting ratio associated with the plurality of database sequences, where the database sequences of the first portion are shorter than the database sequences of the second portion. A first alignment score for the query sequence is determined with the CPU based upon the first portion of the plurality of database sequences and a second alignment score for the query sequence is determined with the GPU based upon the second portion of the plurality of database sequences.Type: GrantFiled: July 19, 2011Date of Patent: August 29, 2017Assignee: KING ABDULLAH UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: M.

Patent number: 8762114Abstract: Disclosed are various embodiments of methods and systems related to fractional order element based impedance matching. In one embodiment, a method includes aligning a traditional Smith chart (|?|=1) with a fractional order Smith chart (|?|?1). A load impedance is located on the traditional Smith chart and projected onto the fractional order Smith chart. A fractional order matching element is determined by transitioning along a matching circle of the fractional order Smith chart based at least in part upon characteristic line impedance. In another embodiment, a system includes a fractional order impedance matching application executed in a computing device. The fractional order impedance matching application includes logic that obtains a first set of Smith chart coordinates at a first order, determines a second set of Smith chart coordinates at a second order, and determines a fractional order matching element from the second set of Smith chart coordinates.Type: GrantFiled: November 3, 2011Date of Patent: June 24, 2014Assignee: King Abdullah University of Science and TechnologyInventors: Khaled N.

Publication number: 20090281422Abstract: A multi-modality system and method for performing detection, characterization and imaging of materials and objects in dense compressive media, such as in medical soft tissue applications, is disclosed. Medical tissue applications include but are not limited to the detection and diagnosis of breast tumors. Generally, an ultrasound subsystem is employed to excite a region in the dense compressive media and a microwave subsystem is employed to collect detection, characterization and imaging information from the excited region. In one preferred embodiment, multiple focused oscillating high-frequency ultrasound wave beams are transmitted into the media. The resultant low beat-frequency wave creates a force inducing motion in the materials and objects in the media. A radio-frequency microwave subsystem detects that motion and produces images based upon the Doppler effects of the excited materials and objects.Type: ApplicationFiled: May 6, 2008Publication date: November 12, 2009Inventors: Khaled N.
