Abstract: The invention provides designs and methods for a heavy vehicle operations and control system for heavy automated vehicles, which facilitates heavy vehicle operation and control for connected automated vehicle highway (CAVH) systems. The heavy vehicle management system provides heavy vehicles with individually customized information and real-time vehicle control instructions to fulfill the driving tasks such as car following, lane changing, route guidance. The heavy vehicle management system also realizes heavy vehicle related lane design, transportation operations, and management services for both dedicated and non-dedicated lanes. The heavy vehicle management system consists of one or more of the following physical subsystems: (1) Roadside unit (RSU) network, (2) Traffic Control Unit (TCU) and Traffic Control Center (TCC) network, (3) vehicles and onboard units (OBU), (4) traffic operations centers (TOCs), and (5) cloud platform.

Abstract: Coding a transform block using level maps is disclosed. A method includes determining a lower plane of values, processing the lower plane in a backward scan order, and selecting a template for entropy-coding the values of the lower plane. The method also includes, for a current value of the lower plane, selecting, based on the template anti-diagonal lines, two or more line buffers, each of the two or more line buffers corresponding to a respective scan-order anti-diagonal line, determining a context using the two or more line buffers, and entropy encoding the current value using the context. Each value is a respective “up-to” value of a transform coefficient. The backward scan order visits the values of the lower plane along scan-order anti-diagonal lines. The template indicates scan positions of coded values of the lower plane, the scan positions are arranged, in the template, along template anti-diagonal lines.

Abstract: Acquiring dynamic data is disclosed including extracting a search term from a search request string that is received, looking up the search term in a threshold value dictionary to acquire a dynamic threshold score corresponding to the search term, using the search term as a query condition and the dynamic threshold score corresponding to the search term as a filter condition to acquire, in an index data table, one or more corresponding pieces of index information, acquiring data information corresponding to the search term based on the index information in the index data table, and sending the data information to be displayed in a page of a website. The dynamic threshold score varies based on a characteristic factor.

Abstract: The present invention discloses a disposable safety self-destruction insulin needle. The invention uses a sleeve-connected linkage structure and realizes an instant reset of the safety sleeve by means of the spring located in the middle axis so as to ensure that the needle tube is not exposed and preferably realizes a tilting and deflection of the self-destruction pressure base due to a plurality of flexible plates unevenly distributed on the inner wall in the needle base so as to finally ensure that the insulin needle cannot be used a second time, in so doing the safety self-destruction operation of the insulin needle is realized.

Abstract: A retractable-type safe self-locking-type self-destructing syringe, which comprises a syringe barrel body (6). A plunger (7) is arranged in the syringe barrel body (6). A needle base is arranged in a barrel neck at an end part of the syringe barrel body (6). A sealing ring (3) is sleeved on the outer wall of the needle base. A head part for needle replacement is formed by the upper part of the needle base. A flexible support engaging piece (4) is arranged within a cavity at the lower part of the needle base. A locking-clutching mechanism matching the end part of the plunger (7) is arranged within the flexible support engaging piece (4).

Abstract: The present application discloses a safety injection needle, comprising a needle base provided on the end potion thereof with a needle tube, characterized in that the needle base being provided at one side with a safety sheath, an elastic telescopic plate being provided at the junction between the safety sheath and the needle base, the safety sheath rotatable about the elastic telescopic plate and having a hollow cavity which is provided therein in sequence with a sheath safety hook and a needle tube safety hook, the needle base being provided with a needle base safety hook cooperating with the sheath safety hook. The safety protection mechanism is integral with the needle base and the multiple-segment engagement mechanism. Compared to the conventional product, the present invention possesses prominent substantive feature and notable development.

Abstract: Embodiments of the present application relate to a dynamic data acquisition method, a dynamic data acquisition system, and a computer program product for dynamically acquiring data. A dynamic data acquisition method is provided. The method includes extracting a search term from a search request string that is received, looking up the search term in a threshold value dictionary to acquire a dynamic threshold score corresponding to the search term, using the search term as a query condition and the dynamic threshold score corresponding to the search term as a filter condition to acquire, in an index data table, one or more corresponding pieces of index information, acquiring data information corresponding to the search term based on the index information in the index data table, and sending the data information to be displayed in a page of a website. The dynamic threshold score varies based on a characteristic factor.
