Abstract: The subject matter of this specification can be implemented in, among other things, methods, systems, computer-readable storage medium. A method includes receiving first image data comprising one or more image frames indicative of a state of a meal preparation area. The method further includes determining, based on the first image data, a first set of one or more detections each indicating at least one of a detected meal preparation item or a detected meal preparation action associated with the state of the meal preparation area. The method further includes receiving order data indicating a plurality of pending meal orders and determining associated meal preparation constraints. The method further includes determining, based on the meal preparation constraints, a first association between the first set of detections and a first pending meal order of the plurality of pending meal orders and performing an action based on the first association.

Abstract: A deep-sea mining device is sunk to a seabed mining area. A window of an exploding wire unit of a pulse exploding wire group is aligned to an exploding area. A strong pulse current is applied to an exploding wire of the exploding wire unit by an intense pulse power supply, and the exploding wire of the exploding wire unit and seawater in an exploding wires area are vaporized to generate shock waves, thereby breaking rocks through the impact of the seawater. The instantaneous high pressure causes the shock waves to crush the ore bed, and the pressure of the shock waves generated by the explosion of the exploding wire can be controlled by controlling the pulse voltage and current, so as to control the crushing head to crush rocks with different thicknesses.

Abstract: A self-pumping hydrodynamic mechanical seal includes a rotating ring (3) and a stationary ring (11). More than three sets of backward curved grooves (39) are provided on a seal face of the rotating ring (3), outlets of the backward curved grooves (39) are provided at an external diameter portion of the seal face of the rotating ring (3), and an inlet (31) connects with a seal chamber (1) through a duct (30) of the rotating ring (3) or the stationary ring (11). When the rotating ring (3) rotates, a medium in the backward curved grooves (39) is accelerated into a high-speed fluid; under a centrifugal force, the high-speed fluid moves to an external diameter side of the rotating ring (3), so as to be pumped into the seal chamber (1) and generates a low-pressure area at the inlets (31) of the backward curved grooves (39); the medium in the seal chamber (1) is driven by a pressure difference, so as to flow into the backward curved grooves (39) through the duct (30), for forming circulation of self-pumping.
