Patent number: 10330596Abstract: The apparatus and method for testing the ability of materials to protect photolabile materials provides an accurate measurement by directly observing the degradation level in a photolabile material. The apparatus is an assembly having primary and secondary cells and a light source. The primary and secondary cells are arranged in different configurations with respect to one another such that any light that reaches the photolabile materials must first go through the protective material under test. The method includes placing a protective material under test in the primary cell; placing a photolabile material in the secondary cell; subjecting the assembly to a light source for a predetermined amount of time; and removing and testing the photolabile material for degradation.Type: GrantFiled: March 27, 2018Date of Patent: June 25, 2019Assignee: King Saud UniversityInventors: Mohd Aftab Alam, Fahad Ibrahim Al-Jenoobi

Patent number: 10067065Abstract: A cover glass of an electronic device may be inspected for defects and damage such as cracks, fractures, scratches, and chips. The electronic device may be placed in an enclosure with a lighting assembly that emits light to the electronic device, and scattered light from defects and damage of the cover glass is captured by an imaging device. A shutter assembly facilitates the capture of scattered light and reduces the capture of reflected light, which enhances the exposure of defects and damage of the captured image of the cover glass. A mirror facilitates the capture of a side surface of the electronic device.Type: GrantFiled: June 23, 2014Date of Patent: September 4, 2018Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Mohammed Aftab Alam, Vikram Srinivas, Nageswara Rao Tadepalli, Bobak Ranjbaran, Ramez Nachman

Patent number: 9992592Abstract: A method of assessing noise involves evacuating air from a vacuum chamber to a pressure less than about 1 Torr and stimulating a device positioned in the chamber by shaking it or by operating a component of the device. Measuring vibrations in a low pressure environment decreases or eliminates propagation of sound waves, thereby enabling isolation and identification of vibrations caused by mechanical noise. These measurements may be useful for more precise acoustic characterization of audio devices containing multiple components.Type: GrantFiled: January 3, 2014Date of Patent: June 5, 2018Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Mohammed Aftab Alam, Ramez Nachman, Vikram Srinivas, Donald Joseph Ashley, Ali-Reza Bahmandar

Patent number: 9837852Abstract: An electronic device with a e-paper display that internally integrates photovoltaic cells and are not apparent from the exterior of the device. A light source of the device injects light into a light guide to front-light the e-paper. Light that leaks from edges of the light guide is captured by the photovoltaic cells. The plastic light guide is also impregnated with a photoluminescent material that absorbs near infrared energy that is incident on a face of the display and re-emits it isotropically to be guided by the light guide to the photovoltaic cells. By combining multiple techniques to illuminate hidden photovoltaic cells, the utility of the hidden cells is maximized.Type: GrantFiled: December 19, 2014Date of Patent: December 5, 2017Assignee: Amazon Technologies, Inc.Inventors: Christopher Dwight Barnes, Mohammed Aftab Alam

Patent number: 9757550Abstract: The dispensing device includes a hollow tube having an open upper end and an open lower end, as well as a horizontal bar disposed between the walls of the hollow tube adjacent to the open lower end. A disc is movably positioned within the hollow tube, the disc having a central aperture defined therein. A string or other flexible member has one end secured to the disc. The other end of the string is drawn downward in the tube, looped around the horizontal bar, then drawn upward through the central aperture in the disc and out the open upper end of the tube. A semi-solid medication is loaded in the tube between the disc and the open lower end of the tube. When the string is pulled out of the upper end of the tube, the disc is drawn downward, dispensing the medication.Type: GrantFiled: February 6, 2017Date of Patent: September 12, 2017Assignee: KING SAUD UNIVERSITYInventor: Mohd Aftab Alam

Patent number: 9645064Abstract: An example method includes positioning a mass at a height opposite a modulator characterized by a particular strain rate and support by a carrier moveably disposed opposite the mass. The method also includes releasing the mass such that the mass impacts the modulator, and an additional component connected to the carrier causes failure of a sample of material. The method further includes determining a displacement of the carrier corresponding to failure of the sample, determining a force applied to the modulator by the mass and resulting in failure of the sample, and determining at least one of a dynamic strength of the sample and a dynamic modulus of the sample. In such a method, the dynamic strength is based on the force applied to the modulator and the strain rate. Additionally, the dynamic modulus is based on the displacement of the carrier and the strain rate.Type: GrantFiled: March 9, 2015Date of Patent: May 9, 2017Assignee: Amazon Technologies, Inc.Inventors: Mohammed Aftab Alam, Ramez Nachman, Shankar Ganapathysubramanian, Guruprasad Ramanathan

Patent number: 9615163Abstract: A loudspeaker port may include tunable physical components to tune the port to different frequencies to improve speaker efficiency at those frequencies. The ports may be activated by at least partly opening associated shutters, or disabled by closing the associated shutters. Activated ports may enhance speaker efficiency in a frequency range. However, activated ports may also introduce sound artifacts, thereby reducing sound quality. Therefore, the ports may be disabled when appropriate to reduce their negative impact to sound quality. A Digital Signal Processor (DSP) may determine the frequency components of a played sound to determine when to open the ports and how to tune the ports. Accordingly, a loudspeaker may benefit from the improved efficiency facilitated by the ports while also avoiding typical drawbacks created by the ports.Type: GrantFiled: December 20, 2013Date of Patent: April 4, 2017Assignee: Amazon Technologies, Inc.Inventors: Ramez Nachman, Mohammed Aftab Alam
