Abstract: Embodiments of the disclosure are directed to a convertible rotor aircraft CRA able to convert between airplane and helicopter flight modes during flight, comprising a tillable proprotor assembly TPA comprising a proprotor. Optionally, the CRA comprises a flight control module FCM configured to control the TPA to reverse direction of thrust generated by the proprotor relative to the TPA when the TPA transitions between a first orientation for helicopter flight and a second orientation for airplane flight. Optionally, the CRA comprises a deployable guard for the proprotors, configured to have a stowed state and a deployed state, wherein: the guard in the deployed state is controlled to be configured as a partially air-permeable barrier.

Abstract: A system for aiming a weapon, the system comprising: an imaging system configured to be mounted to a weapon and acquire targeting images of scenes along directions in which the weapon points; and a display system operable to display the acquired targeting images in directions suitable for convenient viewing by a user.

Abstract: This application provides a wearable apparatus comprising an electronic device, an armband suitable for encircling a portion of a user's arm and physically connected to the electronic device, one or more sensor pads (SPs) operably connected to the electronic device, and a functional module comprised in the electronic device configured to perform a function responsive to activation of the one or more SPs. Optionally, the one or more SPs are positioned in the wearable device so that the functional module performs the function responsive to pressure applied to the armband.

Abstract: A convertible rotor aircraft (CRA) able to convert between airplane and helicopter flight modes during flight, comprising: at least one tillable proprotor assembly (TPA) comprising a proprotor that is tiltable to change the axis of rotation of the proprotor between a substantially horizontal airplane mode and a substantially vertical helicopter mode; and a main rotor system for providing lift during helicopter mode comprising at least one rotor, which produces airflow that flows through at least a portion the proprotor blades of the at least one TPA.

Abstract: A vehicle steering input device comprising: a first knob (102) configured to be rotatable around a first axis of rotation and operatively coupled to a steering column (200) so that rotating the first knob (102) results in rotation of the steering column (200); and a second knob (1112) configured to be rotatable around a second axis of rotation and operatively coupled to rotate the steering column (200) so that rotating the second knob (112) results in rotating the steering column (200), wherein the first and second rotatable knobs (102, 112) are operatively coupled so that rotating one knob (102; 112) in a clockwise (CW) or counter clockwise (CCW) direction results in rotating the other knob (112; 102) in a same direction, and the first axis of rotation and the second axis of rotation define an angle.
