When the system receives output content from a speechlet or skill, the system checks whether the output content is in conformity with the speech quality indicator. If the content conforms to the speech quality indicator, the system may cause the content to be output to the user without further manipulation. But, if the content does not conform to the speech quality indicator, the system may manipulate the content to render it in conformity with the speech quality indicator and output the manipulated content to the user.

US11562733B2 Deep learning models for speech recognition
Presented herein are embodiments of state-of-the-art speech recognition systems developed using end-to-end deep learning.

Embodiments include a well-optimized recurrent neural network (RNN) training system that can use multiple GPUs, as well as a set of novel data synthesis techniques that allows for a large amount of varied data for training to be efficiently obtained. Embodiments of the system can also handle challenging noisy environments better than widely used, state-of-the-art commercial speech systems.

In one example, a processor device of an FaaS cloud computing platform detects an event that triggers execution of a user-defined function, and automatically fetches an environmental metric that represents a current attribute or condition of the operating environment in which the user-defined function will execute. The processor device then calculates a predicted execution duration for the user-defined function based on the environmental metric, and compares the predicted execution duration to an execution duration threshold. If the predicted execution duration exceeds the execution duration threshold, the processor device prevents execution of the user-defined function by the FaaS cloud computing platform.

A polymer composition for the production of shaped objects via selective sintering includes ≥70.0 wt % of poly(ethylene terephthalate), wherein ≥25.0 wt % and ≤90.0 wt % of the poly(ethylene terephthalate has resulted from a selective sintering process as unsintered material. The polymer composition is a powder having a D10 of ≥10 and ≤40 μm, a D50 of ≥75 and ≤100 μm, and a D90 of ≥160 and ≤200 μm. The polymer composition allows for the production of an article having a continuous use temperature of ≥100° C., and results in a low change of molecular weight during exposure to selective sintering powder processing temperatures. Further, the polymer composition allows for a significant reduction of the waste material generated during selective sintering as the unsintered material does not have to be disposed of as waste but may be used again.
US11560450B2 Aliphatic-aromatic polyester having elevated whiteness index
The present invention relates to an aliphatic-aromatic polyester having a whiteness index according to ASTM E 313-73 of at least 25, to a process for preparation thereof and to the use of the aliphatic-aromatic polyester for production of polyester fibers (PF). The present invention further relates to the polyester fibers (PF) comprising the aliphatic-aromatic polyester.
US11560443B2 Grafted polyvinyl alcohol polymer, formulations containing the same, and creping methods
A grafted polyvinyl alcohol polymer includes a polyvinyl alcohol main chain and a plurality of side chains grafted to the polyvinyl alcohol main chain. One or more of the side chains from the plurality of side chains include one or more units selected from: an aliphatic carboxylic acid, an aliphatic amide, an amino alkyl (meth)acrylate, a hydroxylated alkyl (meth)acrylate, or any combinations thereof. The grafted polyvinyl alcohol polymer can be included in a formulation that also includes water, and the formulation can be used as an adhesive in a creping process.
US11560439B2 Hydroxypropyl starch for preparing empty capsules and hydroxypropyl starch-based soft capsules
This invention comprising in hydroxypropyl starch for preparing empty capsules in alimentary and medical use, and hydroxypropyl starch-based soft capsules. This invention takes water as solvent, mix with propylene epoxide and catalyst for reaction, after washing, drying, hydroxypropyl starch is completed. The MS level of substitution of starch is around 2˜5, gelatinization point between 25˜60° C. After the hydroxypropyl starch is gelatinized by heating in water, a hydroxypropyl starch matrix soft capsule can be prepared. The invention consists in introducing hydroxypropyl by modifying the molecular chain of starch to improve the flexibility and hydrophilicity of starch. Therefore, a hydroxypropyl starch matrix soft capsule capable of preparing a flexible and disintegrating property is provided.
US11560436B2 Anti-VWF D'D3 single-domain antibodies fuse to clotting factors
The invention relates to isolated single-domain antibodies (sdAb) directed against von Willebrand Factor (VWF) D′D3 domain and chimeric polypeptides comprising thereof such as blood clotting factors and their uses in therapy such as in the prevention and treatment of hemostatic disorders. The invention also relates to a method of extending or increasing half-life of a therapeutic polypeptide comprising a step of adding to the polypeptide sequence of said therapeutic polypeptide at least one sdAb directed against VWF D′D3 domain.
US11560433B2 Methods of treatment by targeting VCAM1 and MAEA
Antibodies and antibody fragments that inhibit the activity of vascular cell adhesion molecule 1 (VCAM1) and/or macrophage erythroblast attacher (MAEA) are provided, along with formulations and kits comprising these antibodies and antibody fragments and the use of the disclosed compositions, formulations, and kits to treat cancers, sickle cell disease, and Polycythemia Vera.
