  • Publication number: 20240180360
    Abstract: 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.

  • Publication number: 20230417619
    Abstract: 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.

  • Publication number: 20230417609
    Abstract: An electrically conducting substrate includes a plurality of layers. A strain gauge is deposited on a layer of the plurality of layers. The strain gauge measures the stress and/or strain of the electrically conducting substrate. This allows the strain gauge to determine whether a stress or strain of the electrically conducting substrate has caused the electrically conducting substrate to deform, crack, or break.

  • Patent number: 11665865
    Abstract: A system and method for controlling a cooling system for an electronic datacenter component using a two-phase thermal management system with dynamic thermoelectric regulation. The system includes a thermoelectric cooler to transfer heat to a hot conduit of the thermal management system and initialize or maintain a natural convective flow of working fluid by maintaining a temperature difference between a hot and cold conduit.

  • Patent number: 11594261
    Abstract: 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.

  • Patent number: 11419465
    Abstract: A handheld vacuum cleaner includes a main body with a handle extending along a handle axis. The handheld vacuum cleaner also includes a motor assembly positioned within the main body. The handle axis intersects the motor assembly. The handheld vacuum cleaner also includes a dirty air inlet positioned at a front of the handheld vacuum cleaner and extending along an inlet axis. In addition, the handheld vacuum cleaner includes a cyclonic chamber in fluid communication with the dirty air inlet and the motor assembly. The cyclonic chamber defines a separator axis. The inlet axis and the separator axis intersect to form an acute angle extending between the dirty air inlet and the cyclonic chamber. The inlet axis and the handle axis intersect to form an obtuse angle extending between the dirty air inlet and the handle.

  • Patent number: 10693351
    Abstract: 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.
