A movable object for responding to an object includes a first passive infrared sensor having a first detection range and a first field of view, and one or more second passive infrared sensors each having a second detection range and a second field of view. The second detection range is longer than the first detection range and the second field of view is smaller than the first field of view. The movable object further includes one or more processors configured to recognize the object based on one or more heat signals received from at least one of the first passive infrared sensor or the one or more second passive infrared sensors, and perform a flight response measure to control the movable object based on the recognized object. 1. A movable object for responding to an object , comprising:a first passive infrared sensor having a first detection range and a first field of view;one or more second passive infrared sensors each having a second detection range and a second field of view, the second detection range being longer than the first detection range and the second field of view being smaller than the first field of view; and recognize the object based on one or more heat signals received from at least one of the first passive infrared sensor or the one or more second passive infrared sensors; and', 'perform a flight response measure to control the movable object based on the recognized object., 'one or more processors configured to2. The movable object of claim 1 , wherein the one or more processors are further configured to:determine a distance to the recognized object based on a calibration curve and a peak value of an output signal received from at least one of the first passive infrared sensor or the one or more second passive infrared sensors, wherein the calibration curve shows a relationship between distances and peak values.3. The movable object of claim 1 , wherein the flight response measure comprises tracking the recognized object.4. The movable object ...

An unmanned aerial vehicle (UAV) includes one or more propulsion units that effect flight of the UAV, an application processing circuit configured to verify a validity of a system image of the UAV in a secure environment, and a flight control circuit operably coupled to the application processing circuit. Generation and/or transmission of control signals from the flight control circuit to one or more electronic speed controllers (ESC controllers) is prevented prior to verification of the validity of the system image.

Systems, apparatuses and methods for recognizing or detecting obstacles are provided. Passive infrared (PIR) sensors may be coupled to movable objects, such as unmanned aerial vehicles (UAVs). PIR sensors may detect and recognize obstacles such as humans and determine or calculate a distance to the obstacles. Based on the distance from the movable object to the obstacle, one or more flight response measures such as collision avoidance maneuvers may be effected or implemented. 1. An apparatus for detecting an obstacle , said apparatus comprising:a passive infrared sensor on board a movable object, said passive infrared sensor configured to receive one or more heat signals from the obstacle; and 'calculate a distance from the movable object to the obstacle based on data from the passive infrared sensor; and', 'one or more processors, collectively or individually configured todetermine whether to effect a collision avoidance maneuver for the movable object to avoid the obstacle based on the distance.2. The apparatus of claim 1 , wherein the one or more processors are configured to recognize the obstacle based on characteristics of the one or more heat signals received by the passive infrared sensor claim 1 , wherein the recognition of the obstacle comprises differentiating the obstacle from different types of obstacles based on the one or more heat signals.3. The apparatus of claim 1 , wherein the one or more processors are configured to determine a position of the obstacle relative to the movable object.4. The apparatus of claim 3 , wherein the determination of the position of the obstacle relative to the movable object is based on a direction of mounting of the passive infrared sensor and the distance to the obstacle.5. The apparatus of claim 1 , wherein the one or more processors are configured to determine whether to effect the collision avoidance maneuver based on a speed and direction of the movable object and/or the obstacle.6. The apparatus of claim 1 , wherein ...
