Publication number: 20240180360Abstract: A discharging mechanism for automatic cooking device, an automatic cooking device and an automatic cooking method. In the automatic cooking device, a conveyer belt, a discharging mechanism, a cooking component and other operation units are arranged compactly to significantly reduce floor space. A feed toggle device in the discharging mechanism picks ingredient boxes on the conveyer belt and pushes the ingredient boxes to storage platforms. A feed grip device in the discharging mechanism picks an ingredient box on the storage platform and rotates to move the ingredient box over a cooking pot, thereby pouring the ingredient into the cooking pot. Further, the feed grip device rotates the empty ingredient box over a garbage bag hanging ring and enables the ingredient box to fall into a garbage bag. All units in this automatic cooking device are compactly arranged to save space and cover small area, particularly suitable for small kitchens.Type: ApplicationFiled: December 1, 2023Publication date: June 6, 2024Inventors: Chim Lee CHEUNG, Ka Tak LEE, Yao Lin PENG, Kwok Wing YUEN, Lik Choi LEE, Siu Fai MAK, Hing Choi FU, Chun Kit CHAN

Publication number: 20230417619Abstract: A leak detection system for a thermal interface material (TIM) includes a sensor located proximate to a processor. As thermal fluctuations or other events cause the TIM to flow out of the gap between the processor and a thermal management device, a leak detection sensor may detect the presence of the TIM. This allows an operator of the computing device to identify TIM leaks, thereby preventing or reducing damage to the processor or other electronic components of a computing device.Type: ApplicationFiled: June 24, 2022Publication date: December 28, 2023Inventors: Rick Chun Kit CHEUNG, Luke Thomas GREGORY

Patent number: 11594261Abstract: A modular data storage tape library includes a modular frame having a form factor similar to other types of computing racks. The modular data storage tape library includes a hermetically sealed enclosure within the modular frame and a cooling portion within the modular frame. Data storage tapes, data storage drives and robotics for moving the data storage tapes are included within the hermetically sealed enclosure. A heat exchanger transfers heat from the hermetically sealed enclosure to the cooling portion outside of the sealed enclosure through a boundary of the hermetically sealed enclosure without introducing air from the data center into the hermetically sealed enclosure. Because air is neither introduced nor removed from the hermetically sealed enclosure, humidity fluctuations are minimal, if existent, and contaminants are prevented from entering the hermetically sealed enclosure, thus increasing the life spans of the data storage tapes included in the hermetically sealed enclosure.Type: GrantFiled: March 16, 2021Date of Patent: February 28, 2023Assignee: Amazon Technologies, Inc.Inventors: Rick Chun Kit Cheung, Luke Thomas Gregory, Priti Choudhary, Brandyn Giroux

Patent number: 10693351Abstract: A motor driving assembly includes a motor. The motor includes an outer housing, and a rotor and a brush holder received in the outer housing. The rotor includes a rotary shaft extending out of the outer housing. A commutator is fixed on a shaft portion of the rotary shaft within the outer housing. Brushes for contacting the commutator are disposed on the brush holder. A visible identification mark fixed relative to the rotary shaft is disposed outside the outer housing of the motor, such that a relative position between the brushes and the commutator in a rotational direction of the rotary shaft is identifiable by reference to a position of the visible identification mark relative to the outer housing in the rotational direction of the rotary shaft. As such, the commutator can be prevented from stalling at a position where arcing noise may be easily generated.Type: GrantFiled: November 25, 2016Date of Patent: June 23, 2020Assignee: JOHNSON ELECTRIC INTERNATIONAL AGInventors: James Ching Sik Lau, Duncan Yiu Lung Wong, Chun Kit Cheung
