Abstract: A communications system transmits messages via a wireless network to multiple users nearly simultaneously in real-time. Each user has a terminal that receives a message and plays the message for the user. The terminal may also wait for the user to verbally acknowledge the arrival of the message before continuing with its normally executing application. The sender of the message may track, for each intended recipient, the delivery of the message, the accessing of the message by the user, and the acknowledgement by the user that the message was understood.

Abstract: The present invention is an ingenuously designed multiple self locking hinge assembly that is simple to manufacture and can come in a variety of shapes and sizes given the application requirements. It has few parts making it cost effect and simple to use. The hinge assembly can easily be opened and closed with a single hand while at the same time creating a strong hinge connection. The invention can be used in a number of applications, including use with multiple poled devices for many common applications such as crutches, walkers, golf bag and baby carriages to name a few. The invention can also be used in conjunction with devices that require a collapsible frame. The invention also provides lateral strength and stability to a multiple poled device.
