Method and apparatus for transporting passenger baggage

This invention comprises a baggage transport system for handling passenger baggage for transport. In accordance with one or more embodiments of this invention, when a passenger makes a reservation to travel, a passenger identifier number, which may be a ticket or reservation number, is issued and placed in a data collection together with the passenger's transport number, date of travel, time of travel and method of carrier compensation. When the passenger obtains a ticket to a destination, the ticket identifies the passenger identifier, the transport number and date of departure.
Rather than check baggage for carriage at the transport check-in counter, under one embodiment of this invention, baggage is checked for carriage to a destination before departure at a baggage collection facility that is separate from the departure and arrival facility. In the proposed system, passengers will obtain their ticket or passenger identifier at any time in advance of travel and leave off their baggage at a convenient baggage collection center, which may feature drive-in service. The baggage collection center will then accept the baggage for transport to the passengers' ultimate destinations, not merely to the destination transport arrival facilities, which may be airports. Passengers will be able to have their baggage delivered directly to their homes, hotels, offices or other location, rather than having to struggle with baggage at transport arrival facility baggage pickup carousels. Thus, passengers will be able to enter and leave transport arrival facilities quickly and conveniently.

Distributed reinforcement learning stable topology generation method based on adaptive boundary

The invention discloses a distributed reinforcement learning stable topology generation method based on an adaptive boundary, and solves the problems of poor link node connection continuity and stability in routing. The method comprises the following steps of: constructing a node dynamic topology in the mobile ad hoc network; dividing an adaptive reinforcement learning interval and initializing aQ value table; processing the received signal intensity values by sections; performing reinforcement learning in the adaptive interval, updating the Q value by using an adaptive reward function, and judging the stability of the connection state; judging a direct decision interval state; self-adaptively updating the boundary of the self-adaptive interval; and generating a distributed adaptive stable connection topology. According to the method, the received signal strength value is combined with reinforcement learning, adaptive interval boundary updating is combined with adaptive reward function updating, a stable topology link in the dynamic topology change process is accurately achieved, node energy consumption is reduced, large network expenditure is avoided, the learning rate is high, and complexity is low. The method is used for mobile ad hoc network distributed topology generation.

The invention provides a task unloading method based on intention perception in an air-ground integrated Internet of Vehicles. The task unloading method comprises the following steps: constructing a system model; refining the model; proposing a high-reliability low-delay constraint and optimization problem; performing conversion of an optimization problem and track similarity estimation. Accordingto the task unloading method based on intention perception, the user experience quality model, the high-reliability low-delay constraint, the trajectory similarity estimation and the reinforcement learning are combined for selecting the edge server, so that the three-dimensional user intention perception of the user experience quality perception, the high-reliability low-delay perception and thetrajectory similarity perception is realized. Tail distribution of the queue length is also considered, the probability of occurrence of extreme events and the conditional mean value and variance of excess backlog under long-term average time are constrained, queue delay is reduced, queue stability is improved, multi-hop forwarding is not needed, end-to-end delay is remarkably reduced, and the number of times of successful task unloading is increased.

Quantitative device and cooking utensil

PendingCN108143291AAvoid Activity Blocking IssuesImprove smoothness of movementCooking vesselsBeverage vesselsEngineering
The invention provides a quantitative device and a cooking utensil. The quantitative device comprises a storage box body, a box door and a quantitative block, wherein the storage box body is providedwith an outlet; the box door is arranged at the outlet; the quantitative block is located on the lower portion of the storage box body, and a quantitative groove with an upper opening is formed in thequantitative block; the quantitative block can move to enable the upper opening and the outlet to correspond to each other or to be staggered with each other; when the upper opening and the outlet are staggered, the box door shields the outlet to make the outlet closed; when the upper opening and the outlet correspond to each other, the box door avoids the outlet so as to make the outlet opened.According to the quantitative device, the box door is arranged at the outlet of the storage box body, and when the quantitative block moves relative to the storage box body to make the upper opening and the outlet staggered, the box door is used for intercepting fallen materials at the outlet so that the problem that the materials are clamped between the inner wall of the upper opening and the inner wall of the outlet and accordingly the quantitative block is blocked can be avoided, and the moving smoothness of the quantitative block is ensured.
