Publication number: 20240176603Abstract: Aspects of the present disclosure are directed to translating application calls for on-device machine learning execution. A translation layer supports on-device machine learning execution by translating JavaScript software application call data to achieve interoperability with on-device machine learning models. For example, JavaScript software applications interact with data, such as images, audio, video, and/or text, in a format or data type that is compatible with the application. On the other hand, machine learning models interact with data in a form conducive to mathematical operations, such as a data structure representation (e.g., tensor representation). Implementations translate data types and/or data files to provide compatible data to each of a native JavaScript software application and on-device machine learning models.Type: ApplicationFiled: November 29, 2022Publication date: May 30, 2024Inventors: Roman Georg RAEDLE, Christopher Robert Harper KLAIBER, Yinglao LIU, Shiyong FANG, Pranav DESHPANDE, Hung Shek NGAN, Anoop Kumar SINHA

Publication number: 20240080965Abstract: A method for producing a neutrons includes triggering a raising or a lowering of a temperature of a pyroelectric crystal of less than about 40° C. to produce a voltage of negative polarity of at least ?100 keV on a surface of a deuterated or tritiated target coupled thereto. A deuterium ion source is pulsed to produce a deuterium ion beam. The accelerating of the deuterium ion beam is achieved by accelerating voltage of the pyroelectric crystal toward the deuterated or tritiated target to produce neutrons. Furthermore, the pyroelectric crystal, the deuterated or tritiated target, and the deuterium ion source are coupled to a common support. The method also includes throwing the common support housing the pyroelectric crystal, the deuterated or tritiated target, and the deuterium ion source near an unknown threat for identification thereof.Type: ApplicationFiled: October 3, 2023Publication date: March 7, 2024Inventors: Vincent Tang, Glenn A.
