Publication number: 20230103072Abstract: A 1.8-times improved light extraction efficiency (LEE) is reported under DC test conditions for truncated cone AlGaN DUV micropixel LEDs when the pixel size was reduced from 90 to 5 µm. This is shown to be a direct consequence of the absorption of the TM-polarized photons travelling in a direction parallel to the device epitaxial layers. Presently disclosed cathodoluminescence measurements show the lateral absorption length for 275 nm DUV photons to be 15 µm, which is ~1000 times shorter than that for waveguiding in the A0.65Ga0.35N cladding layers. Results show the re-absorption of this laterally travelling emission by the multiple quantum wells and the p-contact GaN layer to be a key factor limiting the LEE. Hence, for DUV emitters, scaling down to sub-20 µm device dimensions is critical for maximizing LEE. Presently disclosed sub-20 µm AIGaN-based LEDs do not show pronounced edge recombination effects.Type: ApplicationFiled: May 18, 2022Publication date: March 30, 2023Inventors: RICHARD FLOYD, ASIF KHAN, MIKHAIL GAEVSKI, MVS CHANDRASHEKHAR, GREGORY SIMIN

Patent number: 11526168Abstract: To implement robotic inspection of an in-service tank through the lower wall, a launch system is operatively coupled to the in-service tank carrying a multiphase fluid separated into a first fluid phase settled at the bottom of the in-service tank and a second fluid phase floating above the first fluid phase. The launch system includes multiple valves and is coupled to the bottom of the in-service tank. By operating the launch system, a robotic tank inspection device is introduced into the first fluid phase in the in-service tank while bypassing the second fluid phase. By operating the robotic tank inspection device, the bottom of the in-service tank is inspected for corrosion.Type: GrantFiled: November 14, 2019Date of Patent: December 13, 2022Assignee: Saudi Arabian Oil CompanyInventors: Zeeshan Farooq Lodhi, Mir Asif Khan

Patent number: 11513986Abstract: To improve data throughput and data transfer rate, a contiguous block of host memory can be allocated for data transfers between the host system and an integrated circuit device such as a peripheral component. By using a contiguous block of memory that acts as a circular buffer, the memory address field of memory descriptors can be eliminated because the host system only need to inform the data movement engine of the length of each data transfer. The data movement engine can maintain pointers to keep track of the memory address in the host memory to read from and write to. After each data transfer, the relevant pointer can be incremented by a value corresponding to the length indicated in the memory descriptor for the transfer. As such, it is not necessary for the host system to provide the data movement engine with the memory address of each transfer.Type: GrantFiled: August 3, 2020Date of Patent: November 29, 2022Assignee: Amazon Technologies, Inc.Inventor: Asif Khan

Patent number: 11275503Abstract: Methods and apparatus are disclosed for securely erasing partitions of reconfigurable logic devices such as FPGAs in a multi-tenant server environment. In one example, a method of securely erasing an FPGA includes identifying one partition of previously-programmed resources in the FPGA, erasing the identified partition by storing new values in memory or storage elements of the identified partition, and storing new values in memory or storage elements of additional external resources electrically connected to the integrated circuit and associated with the identified partition. Thus, other partitions and subsequent users of the identified partition are prevented from accessing the securely erased data. A configuration circuit, accessible by a host computer via DMA, can be programmed into the FPGA reconfigurable logic for performing the disclosed erasing operations.Type: GrantFiled: April 30, 2020Date of Patent: March 15, 2022Assignee: Amazon Technologies, Inc.Inventors: Mark Bradley Davis, Erez Izenberg, Robert Michael Johnson, Asif Khan, Islam Mohamed Hatem Abdulfattah Mohamed Atta, Nafea Bshara, Christopher Joseph Pettey
