US Classification:

473570

Abstract:

An illuminated sports ball including flexible transparent tubing on its exterior for housing and exposing flexible light sources. The tubing is recessed in grooves around the ball so that only a portion thereof projects outward from the exterior surface of the ball. In one embodiment, the grooves terminate at common points on the ball and a central throughbore extends through the ball between these common points. An anchor cord which extends through a bore within the ball may be attached to the ends of the tubes to secure the tubes in the grooves. The tubes may extend within the ball to attach to the anchor cord, or to other tubes positioned around the ball. The light sources are chemiluminescent light sticks which are inserted into the tubes through a central slot. The slot desirably faces the grooves during use and the tubes are torsionally flexible and can be rotated to face outward for inserting the light sticks. In one embodiment the grooves extend in direct paths around the exterior periphery of the ball, while in a second embodiment the grooves follow non-linear paths around the ball.

Abstract:

Disclosed are multi-tenant networked security systems and methods. The system includes a central server, a first user application provided on a first computing device, and a second user application provided on a second computer device, wherein the first and second computing devices are communicatively linked with the central server. The system further includes a persistent network key generated by the central server and based at least in part on a unique request identifier and a transient physical key generated by the first user application and based at least in part on the network key, wherein the network key is received by the first user application. The second user application is configured to communicate with the central server to analyze the network key and the physical key in order to verify that a user of the first user application possesses an ingress permission to an access point.
