Publication number: 20230028215Abstract: A system for coating ceramic fibers for use in manufacturing a ceramic matric composite (CMC) article includes a frame having a plurality of frame members arranged so as to create a void therebetween. At least one of frame members includes a hollow body and at least one perforated hole defined in the hollow body. Thus, the ceramic fibers are securable at respective ends of the frame and extend across the void. The frame also includes an inlet in fluid communication with the perforated hole(s) so as to allow a coating material to flow into and through the hollow body and out of the perforated hole(s) at a location of at least a portion of one of the ceramic fibers. As such, the coating material is configured to cause the portion of one of the ceramic fibers to separate from the frame such that the portion is uniformly coated with the coating material.Type: ApplicationFiled: July 21, 2021Publication date: January 26, 2023Inventors: John Tam Nguyen, Clifford Takashi Tanaka, Theodore Robert Grossman, Reza T.

Patent number: 11492298Abstract: Methods for forming a coated component, along with the resulting coated components, are provided. The method may include forming a silicon-based bond coating on a surface of a substrate and forming a barrier coating on the silicon-based bond coating. The silicon-based bond coating comprises columnar grains of crystalline silicon. Chemical vapor depositing (CVD) may be used to form the silicon-based bond coating through CVD of a silicon-containing precursor at a deposition temperature and deposition pressure that causes crystallization of the silicon material during the deposition of the silicon-based bond coating. The silicon-containing precursor may be silane, monochlorosilane, dichlorosilane, and/or trichlorosilane.Type: GrantFiled: July 31, 2018Date of Patent: November 8, 2022Assignee: General Electric CompanyInventors: Glen Harold Kirby, Justin Michael Nagy, John Tam Nguyen, Jeffery Allen Bross, Brian Harvey Pilsner, Robert Martin Fecke

Patent number: 11095119Abstract: A voltage of a first pin that is one of several pins of an external connector of a system is measured, while the first pin is un-driven except for being pulled to ground through a first resistance, and a second pin of the external connector is being used as a power supply rail of the system. The measured voltage is compared to a short circuit threshold and in response to that threshold being exceeded, the power supply voltage on the second pin is reduced. In such an embodiment, no test stimulus needs to be applied to any of the pins of the external connector. Other embodiments are also described and claimed.Type: GrantFiled: January 28, 2019Date of Patent: August 17, 2021Assignee: Apple Inc.Inventors: Roderick D. Bacon, Nagendra Bage Jayaraj, Derek J.

Patent number: 9926345Abstract: Clostridium difficile is a leading cause of antibiotic-associated infection in hospitals worldwide. There is a need for a vaccine to Clostridium difficile that can target toxic proteins, or that can elicit adequate immunity to prevent infection or reduce the severity of infection. Modified Clostridium difficile toxin A and B (TcdA and TcdB) proteins are described herein, which comprise mutations that reduce toxin A and B toxicity compared to the native toxin. The proteins described are highly similar to the native toxin of Clostridium difficile, but toxicity is reduced.Type: GrantFiled: February 17, 2015Date of Patent: March 27, 2018Assignees: THE HOSPITAL FOR SICK CHILDREN, VANDERBILT UNIVERSITYInventors: Roman Melnyk, Zhifen Zhang, John Tam, Dana Borden Lacy, Stacey A.

Patent number: 9755559Abstract: One embodiment relates to testing and verifying vibrator motor operation during manufacturing of a device and during in-the-field use. The test relies on an integrated motion sensor or other mechanical measurement circuitry, such as, for example, an accelerometer. In one embodiment, a speed determination for a vibrator motor performance during initial manufacture of the device. Subsequently, when vibration is detected during the in-the-field use, the vibration may be sampled using the integrated mechanical measurement circuitry. Once sampled, a speed may be determined based on a resonance of the sampled signal. Over time, the various speed determinations for the vibrator motor may be analyzed to determine an overall health of the vibrator motor. A threshold for detecting when the overall health of the vibration motor over time has degraded may be predetermined. A notification of a degradation of vibrator motor performance is sent to either a manufacturer or user of the mobile communications device.Type: GrantFiled: July 24, 2014Date of Patent: September 5, 2017Assignee: Apple Inc.Inventors: Ching Yu John Tam, Ryan Jeffrey Du Bois, Chanh-Duy Nguyen Tran

Patent number: 9186702Abstract: A mobile device that includes a motion sensor, multiple vibrators, and a motor speed determinator module. The motion sensor senses and records vibrations of the mobile device while the multiple vibrators are simultaneously running. The sensed vibrations are transmitted to the motor speed determinator module, which transfers the sensed vibrations into the frequency domain. The vibrations caused by each of the multiple vibrators are represented by peaks in the frequency representation. In one embodiment, the motor speed determinator module drives each vibrator such that the rotational speed and phase of each vibrator are equal or essentially equal. This is represented in the spectral representation of the frequency domain as the overlapping of each peak into a single peak.Type: GrantFiled: November 28, 2012Date of Patent: November 17, 2015Assignee: Apple Inc.Inventor: Ching-Yu John Tam

Patent number: 9109952Abstract: An electronic device having one or more sensors is provided. The sensors may include any suitable type of sensor that emits or receives radiation (e.g., light waves) from the environment. The electronic device may include openings through which radiation may reach the sensors while keeping the sensors hidden from view. In some embodiments, the sensors may be placed underneath an opening used for an audio receiver such that radiation is piped to the sensors using a light path or a chamfered surface along the opening. In some embodiments, the sensors may be embedded in a screen such that the radiation emitted by the sensors exits the screen instead of being reflected on the screen. In some embodiments, the sensors may be placed along the periphery of the display, such that access to the sensors is provided via discontinuities in a gasket used to couple the display to the electronic device.Type: GrantFiled: November 8, 2013Date of Patent: August 18, 2015Assignee: APPLE INC.Inventors: Richard Hung Minh Dinh, Christopher T.
