Embodiments of the disclosure provide a method for configuring indication information for transportation services. The method includes receiving a first transportation request which includes a first passenger pick-up point located in a preset geographical area, and the first transportation request matches a first vehicle. The method also includes receiving a second transportation request which includes a second passenger pick-up point located in the preset geographical area, and the second transportation request matches a second vehicle. The method further includes generating first indication information for the first transportation request and second indication information for the second transportation request based on a time difference between a first estimated time for the first vehicle to arrive in the preset geographical area and a second estimated time for the second vehicle to arrive in the preset geographical area.

Configuration method and system of indication device for driver-passenger matching

Provided are a method and device for determining a motion trajectory of a target. The method includes: acquiring a transmitted signal, a first echo signal, and a second echo signal of a frequency modulated continuous wave radar; performing a coherent operation on the transmitted signal and the first echo signal, to determine a beat signal therebetween; performing a two-dimensional fast Fourier transform on the beat signal to determine an initial position of the target; performing a short-time Fourier transform on the beat signal to determine a radial velocity of the target; calculating a difference frequency signal between the first and second echo signals; determining a tangential velocity of the target according to the difference frequency signal; inputting the initial position, the radial velocity, and the tangential velocity to a Kalman filter, and receiving a motion trajectory of the target output by the Kalman filter.

Method and device for determining motion trajectory of target

Embodiments of the disclosure provide a method for configuring indication devices in transportation services. The method includes receiving a first transportation request which includes a first passenger pick-up point located in a preset geographical area, and the first transportation request matches a first vehicle associated with a first indication device. The method also includes receiving a second transportation request which includes a second passenger pick-up point located in the preset geographical area, and the second transportation request matches a second vehicle associated with a second indication device. The method further includes determining a time difference between a first estimated time for the first vehicle to arrive in the preset geographical area and a second estimated time for the second vehicle to arrive in the preset geographical area, and sending first indication information to the first indication device and second indication information to the second indication device according to the time difference.

Embodiments of the disclosure provide a method for configuring indication devices in transportation services. The method includes receiving a plurality of transportation requests including passenger pick-up points located in a preset geographical area. The method further includes identifying a first transportation request matching a first vehicle and a second transportation request matching a second vehicle, where the first vehicle and the second vehicle are detected to be located in the preset geographical area. The method also includes determining that first indication information assigned with the first transportation request shares an attribute with second indication information assigned with the second transportation request. The method additionally includes adjusting the first indication information so that the first indication information no longer shares the attribute with the second indication information.

Embodiments of the present invention provide an attachment apparatus and an attachment method for a conductive adhesive. The attachment apparatus includes: a carrier stage, which is provided with at least one working surface, the working surface being configured to support a printed circuit board and provided with a groove, and the groove being provided with a plurality of adsorption holes on its bottom surface; a vacuum adsorption device being connected to each of the plurality of adsorption holes; and an attaching mechanism provided above the carrier stage, and configured to attach the conductive adhesive to a predetermined region of the printed circuit board, and the predetermined region being a region of the printed circuit board to be squeeze connected to a flexible printed circuit board or a chip on film.
