Publication number: 20240075895Abstract: Embodiments are disclosed for crash detection on one or more mobile devices (e.g., smartwatch and/or smartphone). In some embodiments, a method comprises: detecting, with at least one processor, a crash event on a crash device; extracting, with the at least one processor, multimodal features from sensor data generated by multiple sensing modalities of the crash device; computing, with the at least one processor, a plurality of crash decisions based on a plurality of machine learning models applied to the multimodal features; and determining, with the at least one processor, that a severe vehicle crash has occurred involving the crash device based on the plurality of crash decisions and a severity model.Type: ApplicationFiled: September 6, 2023Publication date: March 7, 2024Inventors: Vinay R. Majjigi, Sriram Venkateswaran, Aniket Aranake, Tejal Bhamre, Alexandru Popovici, Parisa Dehleh Hossein Zadeh, Yann Jerome Julien Renard, Yi Wen Liao, Stephen P. Jackson, Rebecca L.

Publication number: 20170057008Abstract: A laser material processing system comprises: a housing defining an engraving chamber, an xy laser beam steering system, a non-telescoping focus mechanism, and a camera system that facilitates production of engravings that exceed the xy dimensions of the engraving chamber and/or facilitates placement of an engraving depicted in a software user interface in a specific location in the work area. The housing includes a removable bottom panel that allows processing of workpieces of infinite thickness. The focus mechanism includes a carriage mirror subassembly, a sliding member moveably attached to the carriage mirror subassembly, and a focusing lens subassembly attached to a lower portion of the sliding member. The carriage mirror subassembly and focusing lens subassembly are configured to receive and focus a laser beam to a focal point. The focusing lens subassembly is adjusted along a z-axis by vertically sliding the sliding member.Type: ApplicationFiled: November 14, 2016Publication date: March 2, 2017Applicant: FULL SPECTRUM LASER LLCInventors: HENRY J. LIU, ZICHEN HUANG, RODNEY CHANG

Patent number: 9492892Abstract: A laser material processing system comprises: a housing defining an engraving chamber, an xy laser beam steering system, a non-telescoping focus mechanism, and a camera system that facilitates production of engravings that exceed the xy dimensions of the engraving chamber. The housing includes a removable bottom panel that allows processing of workpieces that exceed dimensions of the engraving chamber. The focus mechanism includes a carriage mirror subassembly, a sliding member moveably attached to the carriage mirror subassembly, and a focusing lens subassembly attached perpendicularly to a lower portion of the sliding member. The carriage mirror subassembly and focusing lens subassembly are configured to receive and focus a laser beam to a focal point. The focusing lens subassembly is adjusted along a z-axis by disengaging the locking component and vertically sliding the sliding member and is locked into a position by engaging the locking component with the sliding member.Type: GrantFiled: February 10, 2016Date of Patent: November 15, 2016Assignee: FULL SPECTRUM LASER LLCInventors: Henry J.

Patent number: 9266193Abstract: A laser material processing system comprises: a housing defining an engraving chamber, an xy laser beam steering system, and a non-telescoping sliding focus mechanism. The housing includes a removable bottom panel that allows processing of workpieces that exceed dimensions of the engraving chamber and allows stacking of the system on modular attachments for specialized functions. The focus mechanism includes a carriage mirror subassembly attached to the x-axis carriage, a sliding member moveably attached to the carriage mirror subassembly, and a focusing lens subassembly attached perpendicularly to the lower end of the sliding member. The carriage mirror subassembly and the focusing lens subassembly are configured to receive and focus a laser beam to a focal point. The focusing lens subassembly is adjusted along a z-axis by disengaging the locking component and vertically sliding the sliding member and is locked into a position by engaging the locking component with the sliding member.Type: GrantFiled: July 3, 2013Date of Patent: February 23, 2016Assignee: FULL SPECTRUM LASER LLCInventors: Henry J.
