Abstract: A radiation hardened memory cell includes an odd number of storage elements configured to redundantly store an input data logic signal. The storage elements include output lines for outputting respective logic signals having respective logic values. A logic combination network receives the respective logic signals and is configured to generate an output signal having a same logic value as a majority of the logic signals output from the storage elements. An exclusive logic sum circuit receives the respective logic signals output from the storage elements and is configured to produce a refresh of the logic data signal as stored in the storage elements when one of the logic signals output from the storage elements undergoes a logic value transition due to an error event.

Abstract: The current technique provides an unmanned vehicle that is capable of travelling in the air, on the ground and/or in the water. The driving force of the unmanned vehicle is provided by at least one propelling module that includes a motor, a shaft and a propeller. The propelling module is coupled to a chassis. The chassis includes one or more support elements that each couples to one or more aileron member. An aileron member is configured to tilt with or about the support element to change fluid flux about the aileron member and thus change a position of the propelling force.
