  • Publication number: 20240186885
    Abstract: Energy conversion is provided. An energy conversion device can include one or more power delivery interfaces. The energy conversion device can include a pre-charge circuit configured to charge a capacitor to an operating voltage. The energy conversion device can include a user accessible interface configured to provide energy to the pre-charge circuit. The pre-charge circuit can charge the capacitor associated with the one or more power delivery interfaces. The user-accessible interfaces can include a direct current (DC) input. The user-accessible interfaces can include an alternating current (AC) input.

  • Publication number: 20240109834
    Abstract: Prostacyclin compounds and compositions comprising the same are provided herein. Specifically, prostacyclin compounds comprising treprostinil covalently linked to a linear C5-C18 alkyl, branched C5-C18 alkyl, linear C2-C18 alkenyl, branched C3-C18 alkenyl, aryl, aryl-C1-C18 alkyl or an amino acid or a peptide (e.g., dipeptide, tripeptide, tetrapeptide) are described. The linkage, in one embodiment, is via a carbamate, amide or ester bond. Prostacyclin compounds provided herein can also include at least one hydrogen atom substituted with at least one deuterium atom. Methods for treating pulmonary hypertension (e.g., pulmonary arterial hypertension) and portopulmonary hypertension are also provided.

  • Patent number: 11929066
    Abstract: Described are systems, methods, apparatuses, and computer program product embodiments for automatically processing intent-based spoken language for SLU. The disclosed solution uses a scale-free network structured conversational knowledge graph that stores nodes representative of actions, objects, and intent names and edges representative of relationships between the nodes. For all phrases (including a sentence) from the same intent, the system calculates a mean feature vector using a Universal Sentence Embedding (USE) model as a feature element. The system also employs a multi-step intent detection strategy. A graph query technique may be used to match all potential intent nodes from the trained knowledge graph. The system may compute a covariance matrix between the feature element of an input phrase and feature elements of all potential intents. The major component of the covariance matrix along with the maximum covariance may be used to determine the final intent.

  • Patent number: 11487341
    Abstract: Systems and techniques for improving the performance of circuits while adapting to dynamic voltage drops caused by the execution of noisy instructions (e.g. high power consuming instructions) are provided. The performance is improved by slowing down the frequency of operation selectively for types of noisy instructions. An example technique controls a clock by detecting an instruction of a predetermined noisy type that is predicted to have a predefined noise characteristic (e.g. a high level of noise generated on the voltage rails of a circuit due to greater amount of current drawn by the instruction), and, responsive to the detecting, deceasing a frequency of the clock. The detecting occurs before execution of the instruction. The changing of the frequency in accordance with instruction type enables the circuits to be operated at high frequencies even if some of the workloads include instructions for which the frequency of operation is slowed down.
