  • Publication number: 20210129454
    Abstract: Proposed is manufacturing method for a hybrid tube, the method including the step of deriving an optimal ratio between a metal tube and a composite material layer when manufacturing the hybrid tube in which the composite material layer is formed on an outer circumferential surface of the metal tube in order to reduce the weight of an existing metal tube such as a cylinder tube of a hydraulic cylinder. In manufacturing a hybrid tube, it is possible to derive an optimal ratio between heterogeneous materials that can achieve weight reduction while satisfying a target buckling load, thereby making it possible to reduce the weight of tubes of metal materials and apparatuses related to such tubes.

  • Patent number: 10862970
    Abstract: A vehicle controller communicates with a cellular communication system to request content. The content is transmitted to one or more road side units with storage (RSS) lying on the vehicles known or inferred trajectory. When the vehicle passes by the RSS some or all of the content is transmitted to the vehicle using a short-range, high-bandwidth communication protocol. The content may be divided into segments and each segment sent to an RSS. The segments are sized according to a capacity of the RSS and the amount of time the vehicle is expected to spend traversing a range of the RSS. Content may be cached in the RSS for use by other vehicles.

  • Patent number: 10636309
    Abstract: Example vehicle communication management systems and methods are described. In one implementation, a communication management system determines whether a vehicle can communicate with an external system. If the vehicle is unable to communicate with the external system, the communication management system identifies a neighboring device that can communicate with the external system and communicates vehicle information to the neighboring device. The communication management system also requests the neighboring device to communicate the information, and other details from the neighboring device's perspective, to the external system.
