Safe state recognition system for people on basis of machine vision

The invention discloses a safe state recognition system for people on the basis of machine vision, aiming to solve the problem that the corresponding intelligent control decision for the vehicle driving behaviour can not be formulated according to the safe state of the people in the prior art. The method comprises the following steps: collecting a vehicle-mounted dynamic video image; detecting and recognizing a pedestrian in an interested area in front of a vehicle; tracking a moving pedestrian; detecting and calculating the distance of pedestrian in front of the vehicle; and obtaining vehicle real-time speed; and recognizing the safe state of the pedestrian. The process of recognizing the safe state of the pedestrian comprises the following steps: building a critical conflict area; judging the safe state when the pedestrian is out of the conflict area in the relative moving process; and judging the safe state when the pedestrian is in the conflict area in the relative moving process. Whether the pedestrian enters a dangerous area can be predicted by the relative speed and the relative position of a motor vehicle and the pedestrian, which are obtained by a vision sensor in the above steps. The safe state recognition system can assist drivers in adopting measures to avoid colliding pedestrians.

[Automated system and method for providing accurate, non-invasive insurance status verification]

InactiveUS20050209892A1Limiting featureCurrent failureFinanceSpecial data processing applicationsData streamNon invasive
The present invention relates generally to automatic insurance verification, and more specifically, to a non-invasive method and system for automatically determining, by any person with computer, wireless, or telephone access and in real-time, if an insured object of value is or is not insured irrespective of insurer location, jurisdiction, language, type, time, and also the internal operations, software platform and communications protocols used by insurers and/or governmental entities. It is an insurance verification, not an insurance reporting or tracking system and because it maintains no personal data of any kind, and can modify no record, it can deliver only very limited features regarding reporting or tracking. The present invention can however, provide absolute assurance of current insurance status at all times, provides a unique method of access which resolves all current failures and is non-invasive, providing complete privacy for all parties involved, (the absence of all personal information and the access method used ensures that all access and data is inherently non-invasive). This invention further ensures that any check of status, at insurer or governmental registration, (including “e-registration”, inspection, or any other location and time when and where a jurisdiction or insurer requires such a status check, will result in an instant and totally accurate status response. This system is based upon the assignment of a unique identifier, also known in this present art as a “UC” or “Unique Code” which then provides a method of accurate data, (including status checks), without reliance on “VINs”, (vehicle identification numbers), policy number or other identifiers which are often incorrect. The UC is assigned to any combination of two or more elements that are “gleaned”, (file field extraction and related system and methods), one of which is always current status. The extraction of these selected fields from data streams may be done by a number of prior art techniques, and the three most common have been detailed. First demonstrated to government officials in 1999 as a medical version and later the same year as a vehicle version, it has been demonstrated and documented since to a great many Federal and State governmental entities. This present invention has also been demonstrated to several foreign governments but incorporates no technologies that create any possible security risk for any government, insurer, individual, and especially to the national security of the United States.

Composite hard carbon cathode material of lithium ion battery and preparation method thereof

The invention discloses a composite hard carbon cathode material of a lithium ion battery and a preparation method thereof, aiming at improving the first coulombic efficiency. In the composite hard carbon cathode material, a coating object is coated outside a hard carbon matrix, a precursor of the hard carbon matrix comprises a thermoplastic resin which forms the hard carbon matrix by pyrolysis, and a precursor of the coating object is an organic matter. The preparation method comprises the steps of curing, pyrolyzing, pulverizing and coating. Compared with the prior art, a curing agent and adopant are added to the resin for curing, the cured mixture is taken as a carbon source, and then the carbon source is pyrolyzed and coated to finally obtain the composite hard carbon cathode material; and the first reversible capacity of the obtained composite hard carbon cathode material is more than 455.2mAh/g and the first coulombic efficiency thereof is more than 79.4% in the case of 0.2C, thus the obtained composite hard carbon cathode material has high capacity and high first coulombic efficiency, meets the requirement of the lithium ion battery with high capacity, high multiplying power and excellent high and low temperature cycle performance on the charge-discharge performances of the cathode material, has low production cost and is suitable for industrial production.

System and method for improving warehousing transaction security and operation efficiency based on block chain

The invention discloses a system and a method for improving warehousing transaction security and operation efficiency based on a block chain, and aims to solve the problem of low warehousing transaction efficiency due to high difficulty in integrating operation information in warehousing information in the prior art. The whole system combines warehousing with a transaction chain and the internet, and comprises modules including a warehousing service module, a platform management module, a security reinforcement module, a related block chain interface and the like; the security reinforcement module performs bio-feature-based user identity authentication and ensures security of a goods property related interface; and a financial settlement module can manage asset conditions of all users. According to the system and the method, the warehousing is combined with the transaction chain and the internet; two characteristics of "decentralization" and "non-tampering" of the block chain are applied to business operations of warehousing, transaction and the like, so that the security in the complex warehousing and transaction processes is ensured, the manual operation is reduced, and the efficiency is improved; and the system and the method are suitable for the technical field of warehousing supervision information management systems.
