Abstract: This invention adds a touch screen to a hardware keyboard as additional input from handwriting for a PC or a laptop. The new keyboard with a small size touch screen provides convenient ways for handwriting notes, drawing graph or painting, converting handwritten characters to formal text. The new keyboard with a large size touch screen can work with a PC/laptop as a PC/laptop with the advantage of input from touch screen over traditional PC/laptop. The new keyboard with a large size touch screen can work with a PC/laptop as a tablet with the advantage of input from hardware keys and mouse over a regular tablet. The new keyboard with a large size touch screen can work with a PC/laptop as a PC/laptop and a tablet simultaneously, either PC/laptop or tablet with the advantage of additional said input ways over a traditional PC/laptop or a tablet. An optional fingerprint sensor provides fingerprint for security application, e.g., account login, document sign and identity verification.

Abstract: An electronic device with dual screens has a second touch screen for tablet, e-reader/notepad or smartphone. The original or the second screen of the device can choose either e-ink type display or LED/OLED type of display. The combination of e-ink type display for second screen and non e-ink type display for original screen takes advantage of power saving and high-quality image/wide color range from both type of display technology based on the application. Read only permission for application lunched on second screen simplifies the file management system. A virtual keyboard with virtual mouse pad and handwriting touchpad provides ease of mixed input for formal typing or handwriting characters, drawing and digital signature. A laptop or PC with physical keyboard replaced by a touch screen can work as a laptop/PC plus a tablet interchangeably at the same time with ease of mixed input for typing keys, handwriting, drawing and digital signature.

Abstract: Water shortage is a serious problem all over the world. Everyday people use toilet many times and waste lots of water. Some toilet water tank uses half tank of water to flush the pee, but toilet still uses lots of water. In some area without water supply, restroom is very dirty without flush water. This invention can solve those problems with very low cost. Currently, sewage water is discarded after people take shower, wash hands, clothes or food. If the discarded sewage water is collected, filtered and purified, it can be used as toilet flush water. The key factor for this invention is that the water for flushing the toilet does not require high purified quality, so the cost of filtration and purification is very low. This invention could save 30%-60% of the water used in daily life. For the existing building, this invention requires minor modification to separate the water pipes for toilet flush from other usage on both supply and discharge.

Abstract: Safe protection equipment for all vehicles will significantly reduce the collision force by elasticity of springs, tubes and stretchable material in that the springs, tubes or cubic bars with stretchable material will be deformed and compressed when the vehicle bumps to obstacle or two vehicles collide with each other. The reduced colliding force will be passed to the chassis by a frame that will move the vehicle forth or back. This equipment can be used on front, rear, side and corner of the vehicle. Combination of springs with stretchable bars can reduce the collision smoothly. This equipment is attached to the vehicle chassis so the reduced collision force is passed to the vehicle chassis, while the current vehicle can reduce the collision force only by the deformation of the bumper or cover of the body.

Abstract: Safe protection equipment for all vehicles will significantly reduce the collision force by elasticity of material and strength of object with elliptical arch or dome shape, high stiff and tensile strength in that the stretchy materials will be compressed to absorb the energy and reduce the colliding force that is passed to and spread over to the object with strong strength when the vehicle hit an obstacle or two vehicles collide with each other. The reduced colliding force that is spread over a big area instead of focusing on a small spot will be passed to the frame or body of the vehicle with much less damage to the body of the vehicle and the passengers in the vehicle significantly. This equipment will protect both vehicles and drivers without changing the current air-bag protection system. It will significantly reduce the damage for serious collision accidents. This safe equipment can be installed on front, rear, side or corner of the vehicle to replace the bumper or cover of the vehicle door or body.

Abstract: Power and energy saving equipment can save the power to drive the vehicle forward at the same speed and save the energy consumed by the vehicle moving through the same distance at the same speed. When the vehicle with wing installed is moving forward, the pressure between top and bottom of the wing will create the lift force. This equipment utilizes the lift force created by the wing to reduce the friction force between the wheel and the ground. Power and energy saving equipment can partially solve the serious energy shortage problem in the world with relatively low cost. It needs minor modification for the frame and chassis of the vehicle, so the lift force can be passed to the chassis on the vehicle, but it does not need to change the existing engine and driving system. Power and energy saving equipment can be applied to many different type of vehicles such as car, truck, boat and train.

Abstract: Safe protection equipment for all vehicles will significantly reduce the collision force by elasticity of ring and material in that the rings will be deformed and the materials of the rings will be compressed when the vehicle bumps to obstacle or two vehicles collide with each other. The reduced colliding force will be passed to the chassis that will move the vehicle forth or back. The damage to the body of the vehicle and the passengers in the vehicle will be reduced significantly. This equipment can be used on front, rear, side and corner of the vehicle. Combination of rings can reduce the collision smoothly. This equipment will protect both vehicles and drivers without changing the current air-bag protection system. It will significantly reduce the damage for serious collision accidents.

Abstract: Safe protection equipment for all vehicles will significantly reduce the collision force by spring or liquid cylinder when the vehicle bumps to obstacle or two vehicles collide with each other. This equipment can be used on both front and rear of the vehicle. Combination of springs or liquid cylinder with different elasticity can reduce the collision smoothly. This equipment will protect both vehicles and drivers without changing the current air-bag protection system. It will significantly reduce the damage for serious collision accidents. This equipment is attached to the vehicle chassis on bottom, which will bear the collision force reduced by the spring or liquid cylinder. It might require some design change in vehicle chassis. One option is to add a pad to pass the reduced collision force to the elastic tire when colliding vehicles are running in straight line.
