Abstract: A network system obtains position information from a plurality of computing devices that are located within a geographic region where a mass-user facility is provided. A congestion level is determined for an area of the geographic region, based at least in part on the position information obtained from the plurality of computing devices. In response to determining that the congestion level exceeds a threshold level, the network system determines a target distribution profile for managing the use of multiple egress points by users within the geographic region to reduce the congestion level. Application content data can be transmitted to individual computing devices to cause corresponding users to use a corresponding of the multiple egress points, in accordance with the target distribution profile.

Abstract: Example embodiments are directed to systems and methods for providing pickup point assistance. In example embodiments, a network system uses data received from one or more sensors to detect a location of a user that is requesting a transportation service. The network system also tracks, a driver along a route to the pickup point. Based on the tracking, an estimated time of arrival (ETA) of the driver at the pickup point is determined. Using the location of the user and the ETA of the driver, the network system performs analysis to determine whether an issue exists that affects the rider arriving at the pickup point on time to meet the driver. Based on the analysis, a notification to the user regarding the issue is automatically presented, whereby the notification is displayed on a device of the user.

Abstract: A carbon dioxide-lured mosquito trapping device includes a main body, as well as a net cover assembly, a fan, and a mosquito storage box that are sequentially arranged from top to bottom in a height direction of the main body. The net cover assembly is provided with an air inlet part and an air outlet part, and under the action of the fan, air enters the mosquito storage box from the air inlet part and is finally discharged from the air outlet part. A carbon dioxide mosquito luring part configured for generating carbon dioxide gas arranged on a side of the main body is further included. The carbon dioxide mosquito luring part includes a discharge hole formed in the net cover assembly for outputting carbon dioxide gas. Despite of a simple overall structure and a low cost, the device of a simple structure achieves mosquito luring and trapping functions.

Abstract: A mosquito trapping device includes a body, a mosquito storage box, a fan, and a lattice cover assembly, where the lattice cover assembly is arranged on an upper end portion of the body and forms a first accommodation space with the body, and the mosquito storage box is mounted on the body; the fan causes air to flow through air inlet portions so as to enter the mosquito box and subsequently flow through the accommodation space and air outlets which together form an air duct used to trap mosquitos in the mosquito storage box.

Abstract: An electroplating device includes a process chamber, a substrate holding device, a first cover body, a second cover body, a gas supply part and an exhaust part. The electroplating solution is contained in the inner chamber of the process chamber and the inner chamber has an opening. The substrate holding device is used for holding a substrate, and the substrate holding device is moved into or out of the inner chamber through the opening. The first cover body is connected to the substrate holding device to close the opening after the substrate holding device is moved into the inner chamber, so that the inner chamber is in a closed state. The second cover body is used for closing the opening after the substrate holding device is moved out of the inner chamber, so that the inner chamber is in the closed state again.
