Abstract: A mobile crutch to facilitate improved ambulation of an impaired individual. The device includes a substantially rectangular vertical frame having two parallel vertical frame members, two transverse horizontal frame members, two rigid wheel assemblies, a handle and a brake. The mobile crutch is made from commercially available components. The mobile crutch includes wheels adjacent to the ground attached to the bottoms of the vertical members. The wheels allow the user, supported by the rigid arm rest, to maintain continuous ground contact and walk in an upright posture with uninterrupted strides.

Abstract: Described herein is a mobile crutch to facilitate improved ambulation of an impaired individual. The device consists of an elongated frame of two parallel members and connecting horizontal transverse cross-members. The top horizontal cross-member positioned under the arm and provides the initial support area for the individual. Each vertical frame member is designed to extend from the area of the shoulder to the bottom length of the frame which includes wheels adjacent to the ground surface and a manually manipulated brake feature that can be employed to immobilize the crutch when ascending or descending on or over obstacles such as curbs, motorized walkways, escalators etc., or during extended periods of inactivity while standing.

Abstract: In a telecommunications/data network (10), IP control channels between out-of-band control plane entities are automatically created through discovery of information by state machines implementing an ICDP (IP Control channel Discovery Protocol). Control plane entities executing the protocol send address information in BootStrapMessages and optional GatewayMessages through their local network element to a far-end network element and wait for similar messages from the far-end network elements. When the information is received, control channels are created, if they do not already exist.
