Abstract: Apparatus and associated methods relate to a balance exercise training equipment having a planar platform with a ballast assembly that lowers its center of mass below a ball-and-socket joint. In an illustrative example, the planar platform may couple to a support assembly through the ball and socket joint to pivot and rotate relative to the support assembly. The ballast assembly may include laterally extending members to releasably receive and retain ballast plates. In response to the laterally extending members receiving and retaining ballast plates, the center of mass may descend below a pivot point of the ball-and-socket joint. In a mount or dismount mode, a locking mechanism may lock the planar platform in a predetermined position to facilitate mounting and dismounting onto the planar platform. Advantageously, a user may adjust the center of mass in accordance with a user's skill level or exercise preference.

Abstract: Each of a first group of gateway nodes of a communications network operates as a primary gateway identified by a respective unique gateway identification number (GWID), and each of a second group of gateway nodes operates as a backup gateway. Each gateway node has an assigned backup priority level with respect to each GWID. The gateway nodes are interconnected via a common local network. In the event that a primary gateway node becomes non-operational, the backup gateway that is assigned the highest priority level with respect to the GWID of the non-operational primary gateway assumes operation as the primary gateway identified by that GWID. Upon restoration of the non-operational gateway node, the gateway node operates as a backup gateway in place of the gateway node that assumed its operation as the primary gateway. A gateway node operates as a primary gateway for only one respective GWID at a time.
