The at least one lid is pivotally attached to the box main body of at least two hinge modules. Each hinge module comprises a pin module having a hinge pin with a front end, a rear end, a longitudinal axis about which the lid is pivotable and predominantly a smooth outer surface of a cylindrical shape. Each hinge module further comprises a bearing module having a hinge bearing accommodating the hinge pin. The hinge pin laterally extends with its front end into the hinge bearing. Thus, during pivoting the lid with respect to the box main body an axis of the hinge bearing remains co-linear with the longitudinal axis of the hinge pin.

Abstract: Authenticating the location of a viewing device for receiving content includes storing a plurality of connection identifiers in a database, the connection identifiers being associated with a plurality of networking devices and a plurality of user accounts. A viewing device sends a request to access content which is received by a server. The request is associated with a user account. One or more first connection identifiers is selected from the database based on the user account to which the request is associated. A second connection identifier is obtained based on a connection between the viewing device and the server. It is determined if the second connection identifier matches one of the one or more first connection identifiers. Content is provided to the viewing device if the second connection identifier matches one of the one or more of the first connection identifiers.

Abstract: The present invention describes an air-burst projectile (100) and a system (200) for deploying the airburst projectile to counter an unmanned aerial vehicle (UAV) 10. Each airburst projectile includes one or more spinners (140, 140a-140d); each spinner has a sleeve or a tube (146), a number of radial partition plates (148, 148a-148d) extending from the sleeve/tube and an annular rear plate (144) connected to the sleeve. Adjacent partition plates thus form a compartment (150). Disposed in each compartment is a streamer or streamers (170,170a,170b), which are formed in a coiled-up state. When the airburst projectile is deployed into a flight path of a target UAV, the spinners (140, 140a-140d) are ejected and the streamers (170,170a,170b) are dispersed in the flight path to create a streamer cloud, so that a streamer may entangle with propellers of the UAV and bring down the UAV, or as a warning or fence marking shot.
