  • Patent number: 11352193
    Abstract: A moisture resistant pad for a liquid crystal panel, including at least one moisture resistant construction including a central region and an edge region disposed around the central region, wherein the edge region includes a first undulation structure disposed around the central region, the first undulation structure being a closed structure for blocking water vapor out of the central region. In the moisture resistant pad for a liquid crystal panel, channels formed within a surface of a product that needs to be moisture resistant are isolated from the external environment so that water vapor in the external environment cannot contact the product surface through the channels. As a result, the pad has good moisture resistance, suitable in transportation environments or in packaging container environments.

  • Publication number: 20220148425
    Abstract: A computer system can determine historical interval data of a freight operator from completed freight service requests associated with the freight operator. Additionally, while the freight operator is fulfilling a current freight service request, the computer system can determine at least a first likely downtime interval for a non-operating activity of the freight operator prior to the freight operator arriving at a pickup location or a destination location of the current freight service request, based on the historical interval data. Also, the computer system can determine an estimated arrival time for the freight operator to arrive at the pickup location or the destination location of the current freight service request, based at least in part on the first likely down time interval. Moreover, the computer system can update a record associated with the freight operator to reflect the estimated arrival time.

  • Publication number: 20220130127
    Abstract: In various embodiments, a training application trains a machine learning model to modify portions of shapes when designing 3D objects. The training application converts first structural analysis data having a first resolution to first coarse structural analysis data having a second resolution that is lower than the first resolution. Subsequently, the training application generates one or more training sets based on a first shape, the first coarse structural analysis data, and a second shape that is derived from the first shape. Each training set is associated with a different portion of the first shape. The training application then performs one or more machine learning operations on the machine learning model using the training set(s) to generate a trained machine learning model. The trained machine learning model modifies at least a portion of a shape having the first resolution based on coarse structural analysis data having the second resolution.

  • Publication number: 20210375273
    Abstract: An utterance in any of various languages is processed to derive a predicted label using a generated grammar. The grammar is suitable for deriving meaning of utterances from several languages (polyglot). The utterance is processed by an encoder using word embeddings. The encoder and a decoder process the utterance using the polyglot grammar to obtain a machine-readable result. The machine-readable result is well-formed based on accounting for re-entrances of intermediate variable references. A machine then takes action on the machine-readable result. Ambiguity is reduced by the decoder by the well-formed machine-readable result. Sparseness of the generated polyglot grammar is reduced by using a two-pass approach including placeholders which are ultimately replaced by edge labels.
