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.

Multi-environment flexible vehicle

A method of detecting objects includes transmitting toward an object a first acoustic signal including a first set of pulses including a first number of pulses, and checking if a first echo signal resulting from reflection of the first acoustic signal is received with an intensity reaching an echo detection threshold. If the intensity of the first echo signal reaches the echo detection threshold, the distance to the object is calculated as a function of the time delay of the first echo signal. If the intensity of the first echo signal fails to reach the echo detection threshold, one or more further acoustic signals are transmitted including a set of pulses wherein the number of pulses is increased with respect to the number of pulses in said first acoustic signal.

Method of detecting objects and corresponding apparatus

A device for detecting obstacles that is wearable by a subject, for example integrated in an item of footwear. The device includes an ultrasound source for emitting an ultrasound transmission signal and an ultrasound receiver for receiving a corresponding ultrasound signal reflected by an obstacle, a control module for measuring a time of flight between emission of the ultrasound transmission signal and reception of the corresponding ultrasound signal reflected by the obstacle and calculating, on the basis of the aforesaid time of flight, the distance at which the obstacle is located. The device comprises an inertial sensor, in particular an acceleration sensor, designed to measure acceleration of the foot along three axes, and a control module configured for enabling operation of the ultrasound source if the aforesaid acceleration values measured by the inertial sensor respect a given condition for enabling measurement of the time of flight.
