  • Patent number: 12661977
    Abstract: A modular assembly for a fuel-cell vehicle is configured to connect to a bracket arranged along a longitudinal frame of the vehicle. The modular frame can include one or more components for powering the vehicle, including one or more of a fuel cell, a battery, a battery cooling system, and hydrogen storage tanks. The modular assembly can communicate with the fuel-cell vehicle through standard integration components regardless of the particular components in the modular assembly. The modular assembly can be readily removed from the fuel-cell vehicle and replaced with a different modular assembly containing different components.

  • Publication number: 20240240658
    Abstract: A hydraulic module is provided for a materials-handling vehicle. The hydraulic module can include a mounting frame configured to mechanically connect to a frame of the vehicle but isolate the vehicle frame from vibrations occurring in the power pack. The mounting frame supports the primary components of a hydraulic energy recovery system, including, for instance, a hydraulic tank, a hydraulic pump, and an electric motor. The hydraulic energy recovery system components can be secured to the mounting frame before the mounting frame is connected to the vehicle frame. Standardized integration components such as cables, tubes, and wiring can be used to connect the module to the electrical and hydraulic systems of the vehicle. A fluid level sensor and indicator can be provided to indicate the fluid level of the hydraulic tank. Check valves can be mounted to adapter blocks to ensure low delta pressure during operation.

  • Patent number: 8566096
    Abstract: A system to generate a response to a text-based natural language message includes a user interface, processing device, and a computer-readable storage medium storing executable instructions to generate the response to the text-based natural language message. The instructions and a method for generating the response include identifying a sentence in the text-based natural language message, identifying an input clause in the sentence, and parsing the input clause, thereby defining a relationship between words in the input clause. The instructions and method also include assigning a semantic tag to the parsed input clause, comparing the input clause to a previously received clause, the previously received clause being correlated with a previously generated response clause, and generating an output response message derived from the previously generated response clause.

  • Patent number: 8296140
    Abstract: In accordance with one aspect of the present invention, an automated method of and system for generating a response to a text-based natural language message is disclosed. The method includes identifying a first selected input clause in a sentence in the text-based natural language message. Also, assigning a semantic tag to the first selected input clause and matching the semantic tag to a historical input tag. The historical input tag associated with a first previously generated response clause. Further; generating an output response message based on the historical response clause, the output response message derived from the historical input tag and a second previously generated response clause. The system includes means for performing the method steps.

  • Patent number: 8195588
    Abstract: Disclosed is a method and system for identifying critical emails. To identify critical emails, a critical email classifier is trained from training data comprising labeled emails. The classifier extracts N-grams from the training data and identifies N-gram features from the extracted N-grams. The classifier also extracts salient features from the training data. The classifier is trained based on the identified N-gram features and the salient features so that the classifier can classify unlabeled emails as critical emails or non-critical emails.
