Abstract: A portable communication system for use in hostile and unknown environments. The system has a base station for control by an operator. The base station dispatches one or more unmanned drones into the hostile environment, where a forward agent, such a robot or investigative person can approach a suspected threat. Each drone has a payload of repeaters to be delivered as necessary to maintain line of sight communication from the forward agent back to the base station. Once delivered, the repeaters are mobile and can autonomously reposition to maintain or optimize line of sight communication. Communications from the forward agent back to the base station are then interpreted and analyzed for further action.

Abstract: A locomotion safety and health assistant can utilize a quad cane and have integrated thereon a suite of sensors, microcontrollers, power sources, external communication devices, lights, tactile communication devices, alerts and activation sensors. A plurality of environment sensors can monitor the terrain ahead, watching for obstacles or changes in elevation. The assistant can provide communication with the user to warn of any obstacles or dangers. A switch can allow the user to turn on a light that is directed to the front of the assistant and lights up the terrain ahead. The assistant can include a programmable medication alert. Additionally, a pulse sensor or other health sensor can be incorporated therein. Measurements therefrom can be compared to ranges and warnings communicated when outside of a safe range; thereby providing warning that it may not be safe to stand and walk as fall susceptibility is unduly high at present.
