Abstract: The present invention discloses a VTOL aircraft with retractable wings and TEMCS (trailing edge mounted control surface) mounted tilt-able engines. The aircraft has two hover modes; a first hover mode with retracted wings which allows takeoff and landing in tight landing spots, and a second hover mode with extended wings, during these hover modes, the aircraft operates as a multi-rotor aircraft with additional means of vectored forces created by tilt-able engines, with engines directed upward, and a cruise mode with the wings extended and the engines directed in forward direction.

Abstract: A portable modular solution for a workout mace, including a multi section handle, and a mace head capable of having variable weights, where the solution allows adding many different handles, ad-ons and accessories such as different handles for an all-round workout with a single device. The carrying bag/backpack of the modular system may be made in the form of a vest and be doubled as a weight vest.

Abstract: A tail sitting VTOL aircraft with nonplanar tandem rotor blown wing configuration, capable of traveling in an airplane mode, and a hover mode during take-off and landing with fuselage oriented vertically, with capability to have precise controlled hover, and capability of making controlled and safe assisted transition between two modes during a horizontal movement and without need for much headroom and overhead clearance. The aircraft includes a fuselage, a nonplanar wing configuration which includes plurality of wings in different planes and at least 1 stabilizer, the wings having a leading edge defining the forward direction of flight in airplane mode, and a trailing edge, and at least 1 proprotor connected to the airframe through a rotatable drive shaft, plurality of rotor blown surfaces with various orientations may be used to provide high precision hover and controlled assist during transition. Embodiments with at least 3 proprotors may also have multirotor capabilities in hover mode.

Abstract: The present invention discloses oblique revolute joint solution for connection of the wings of a VTOL aircraft with retractable wings. The aircraft has a hover mode and operates as a multirotor aircraft when the wings are retracted with the rotors directed upward and has an airplane mode when the wings are extended with the proprotor directed in forward direction. The transition between two modes may be done on the ground or during a forward flight.

Abstract: A multi-purpose wearable prophylactic and intimacy aid device made of a material mimicking human flesh, used during a sexual relationship having different purposes such as but not exclusive to providing, independently or in combination with a body part of the wearer at least one entryway to receive a means of penetration, reducing skin to skin contact to decrease the risk of STDs, and enhancing the size and shape of parts of the body of the wearer.

Abstract: A solution is described which by meant of thermal expansion keeps the tension of the strings of a stringed musical instrument constant in every temperature and humidity level. Then it nearly eliminates the effect of temperature and humidity changes on the pitch of the stringed musical instruments. Different mechanisms are suggested in order to employ this invention.

Abstract: This invention provides a steering mechanism solution for increasing the stability of 3 wheel cars. This invention is suitable for a 3 wheel car, with 2 fixed wheels on one end, and one steerable wheel on the other end. According to this invention, by employing a 4 bar linkage mechanism, which can be upgraded to a 5 linkage mechanism, the steerable wheel position will be shifted in a way to increases the distance between the center of gravity of the car and the tipping line. The stability of a 3 wheel car with this steering mechanism can be compared with a 4 wheel vehicle.

Abstract: This invention features a solution to use a pocket size pc, smartphone, or tablet or any other type of mobile personal computer as the main computer of a vehicle, in the highly computerized future vehicles. By connecting the smartphone/tablet/etc to the car interface, the phone/tablet/etc will become the brain of the machine, and acts as a vehicle computer system. By the use of the car manufacturer application software, or use of 3rd party application software, It can be programmed for controlling/replacing many of the vehicle subsystems and accessories.
