An aerosol detection system for detecting airborne organic matter, the detection system including a corridor extending along a longitudinal axis and having first and second ends; an access gate connected to the first end of the corridor and configured to control access of an individual to the corridor; a person detection system located in the corridor and configured to determine the presence of the individual inside the corridor; and a testing set configured to generate an air puff, which directs an exhaled breath of the individual for determining a presence of the airborne organic matter. The corridor has a width w.sub.c that allows movement of a single individual past the testing set.

A visitor management system, which can accurately determine if a visitor presents a proper ticket for the visitor's personal attribute, includes: a reader configured to read ticket information in a ticket medium; a camera configured to capture an image of the visitor; a control device configured to acquire a personal attribute of the visitor from the captured image, determine if consistency is achieved between the ticket information from the reader and the acquired personal attribute, and generate a management screen including determination result information; and a display configured to display the management screen. The determination result information generated by the control device may include a number of persons for each ticket type and a number of persons for each personal attribute, and inconsistency information indicating that consistency is not achieved.

A computer device for enhancing security of a secured area that comprises a video input device and a processor configured to receive a request to access the secured area at an access point associated with the secured area, obtain an image data of a secure boundary area associated with the access point, determine the number of users in the secure boundary area based on the image data, determine whether to grant an access in response to the request based on one or more rules, grant the access in response to the request in accordance with the rules when the number of users in the secure boundary area is less than or equal to a threshold, and deny the access in response to the request in accordance with the rules and when the number of users in the secure boundary area is greater than the threshold.

Various embodiments are directed toward systems and methods relating to security screening. For example, a screening system includes chamber scanners oriented to scan different heights corresponding to different respective portions of a user, to identify whether the user is carrying an item that is to be divested. The screening system also includes a divestment scanner configured to obtain a detailed item characterization of the item divested from the user.

A credentials verification system for controlling compliance with required carrying of permit cards at construction work sites has an association database with stored data that correlates work permits with RFID data corresponding to RFID tags, where a respective and unique RFID tag is assigned to and irremovably attached to each work permit. A local control system at each work site includes: an RFID tag reader that reads an RFID tag wirelessly when a worker approaches within a predetermined distance of the RFID tag reader; a local processor and a software facility associated with the local processor that verify that a sensed RFID tag is authorized; and an entry controller operating under the local processor for controlling the entranceway into the work site so as to admit a worker only when the worker has been determined to carry the required work permit(s).

The present disclosure relates to an intelligent prevention passage control system for an electronic device, which comprises a detection device for an electronic device, a traffic control device integrated with the detection device for the electronic device, an industrial control host, a server, an access controller and a management terminal inside the traffic control device. The present disclosure can more accurately judge violations by scoring violations, and can make the system more intelligent by accurately judging violations, thus realizing no manual attendance, solving the problems of personnel recruitment, shift attendance and personnel management, and saving a lot of labor cost. At the same time, the system can avoid the hidden dangers caused by human feelings, sense of responsibility and inertia brought by manual prevention, and ensure the consistent, accurate and reliable standards of detection work.

The invention relates to a passage device comprising: at least one passage traversable by at least one person along a passage direction; at least two sidewalls spaced from each other along a direction extending perpendicularly to the passage direction, the sidewalls being connected with each other, wherein the passage is bounded along the direction by the sidewalls, and at least one capturing device by means of which a body temperature of the person located in front of at least a partial area of the passage along the passage direction can be contactlessly captured, wherein the passage device, considered on its own, is formed as a structural unit assembled and mobile.
