摘要： A two-phase immersion cooling system for cooling electronics. The electronics are immersed in immersion tank filled with phase change liquid. As liquid evaporates due to heat generated by the electronics, it enters a vapor passageway that leads the vapor to a condenser situated remotely from the immersion tank. Upon condensing at the condenser, the condensed liquid is directed to a resupply tank, wherein the condensed liquid cools. When the level of the two phase liquid in the immersion tank drops below a set threshold, a pump is activated to deliver the condensed liquid from the resupply tank to the immersion tank. The immersion tank, vapor passageway and condenser are position inside a containment passageway. The containment passageway captures any vapor not entering the vapor passageway and direct such vapor to the condenser. An air mover generates pressure differential within the containment passageway to direct the vapor towards the condenser.

摘要： In one embodiment, a method for calculating a location of an autonomous driving vehicle includes receiving new global navigation satellite system (GNSS) data. The method further includes identifying a first previously estimated location from a plurality of previously estimated locations with a timestamp that is closest to the timestamp of the new GNSS data and identifying a second previously estimated location from the plurality of previously estimated locations with a most recent timestamp. The method further includes calculating a difference between the first previously estimated location and the second previously estimated location, adjusting the new GNSS data based on the difference; and calculating a current estimated location of the ADV based on the adjusted GNSS data.

摘要： Model pruning is used to trim large neural networks, like convolutional neural networks (CNNs), to reduce computation overheads. Existing model pruning methods mainly rely on heuristics rules or local relationships of CNN layers. A novel hypernetwork based on graph neural network is disclosed for generating and evaluating pruned networks. A graph is first constructed according to information flow of channels and layers in a CNN network, with channels and layers represented as nodes and information flows represented as edges. A graph neural network is applied to aggregate both local and global dependencies across all channels and layers of the CNN network, resulting in informative node embeddings. With such embeddings, pruned CNN networks including their architectures and weights may be effectively generated and evaluated.

摘要： A cooling plate for cooling high power density electronics has an internal cavity and an opening for fluid exchange with the cavity. A mounting structure is positioned within the opening. A coaxial port is attached to the mounting structure, the coaxial port having a center conduit and a ring conduit surrounding the central conduit such that rotational axis of the center conduit coincides with rotational axis of the ring conduit. A single coaxial port can serve to deliver cooling liquid to the cooling plate and return warmed fluid from the cooling plate. The coaxial port center conduit connected with a fluid distribution panel. Fluid distribution is regulated by the panel before it exits the port through the ring conduit.

摘要： Methods, systems, and devices for managing coolant in data centers are disclosed. Coolant may be used in data centers to regulate the temperatures of computing devices. The disclosed methods and system may provide for containment of vapor and condensation of the vapor into coolant. The coolant may be used as part of a two phase cooling system to cool the computing devices. The vapor may be generated when the coolant removes heat from computing devices during operation while at least partially submerged in the coolant. A mobile condenser is used for condensing the vapor within the containment.

摘要： According to one embodiment, an immersion cooling system may include a container to receive one or more server blades, each having electronics, at least partially submerged within a two-phase coolant contained within the container. The immersion cooling system may also include a cover panel to cover the phase change area. This area may include a liquid region defined to contain the two-phase coolant therein, and a vapor region defined between the cover panel and a surface of the two-phase coolant. The cover panel includes a plurality of slots, covered with rotatable panels. At least one of the slots is configured to allow a server blade to be inserted into the liquid region and at least partially submerged into the two-phase coolant. The slots may be configured to allow a condensing unit to be inserted into the vapor region.

摘要： Embodiments are disclosed of a fluid connection module. The module includes a holder coupled to a connector having an axis, and the holder is translatable in both directions of the axis so that the holder and the connector can translate between an engaged and disengaged positions. The holder is biased toward the disengaged position. A switching unit adjacent to the holder includes an electric motor. A blade is coupled to the electric motor and is rotatable through a range of angular positions. The blade has a contact surface that contacts a bearing surface of the holder in a first subrange of angular positions and stops contacting the bearing surface in a second subrange of angular positions. When the contact surface is in contact with the bearing surface, the holder is in its engaged position. An elastic torque member is coupled to the motor and the blade and biases the blade to an angular position in the second subrange.

摘要： Presented herein are embodiments of a multimodal Recurrent Neural Network (m-RNN) model for generating novel image captions. In embodiments, it directly models the probability distribution of generating a word given a previous word or words and an image, and image captions are generated according to this distribution. In embodiments, the model comprises two sub-networks: a deep recurrent neural network for sentences and a deep convolutional network for images. In embodiments, these two sub-networks interact with each other in a multimodal layer to form the whole m-RNN model. The effectiveness of an embodiment of model was validated on four benchmark datasets, and it outperformed the state-of-the-art methods. In embodiments, the m-RNN model may also be applied to retrieval tasks for retrieving images or captions.
