Abstract: A new type of vehicles is disclosed that equipped with a steering wheel which can be located and operated either in side location or in central location. The information display panel, the brake pedal, and the acceleration pedal can be moved along with the steering wheel, the central convenient cabin can be moved to side also. When the steering wheel is located at the central position, additional about 1 foot or more collision cushion space is created which will substantially reduce the injuries and fatal casualties caused by side collisions.

Abstract: A lifesaving apparatus is disclosed that contains a free rotation wheel which has a vertical rotation axis, multiple such lifesaving apparatuses are installed at the left, right and middle section of the front of the vehicle. When the vehicle collides with an object in non-perpendicular angle relative to the collision surface, the wheel will rotate and cause the vehicle to move along the collision surface until all energy is released, the lifesaving apparatus will substantially reduce the impact force on the vehicle and on the people in the vehicle, therefore, the deaths, injure and the damage of the vehicle will be dramatically reduced.

Abstract: A new portable multiple function appliance is presented for the people who have to stay in bed for prolong time or their rest of life due to various reasons to take care most of their daily life needs by themselves with one functional arm and hand; such portable multiple function appliance combines a hot and cold water dispenser, a refrigerator, a microwave oven, a central operation unit, a bed tray table with a lamp, three waste containers and a moving cart. This appliance is placed besides a bed, the people in the beds can operate the appliance for their daily life needs, i.e. get the food out the refrigerator, put it into the microwave oven to warm it, get hot or cold water, make a cup of coffee or tea, take medicine or clean themselves by changing diapers and wipe themselves, put the wastes into waste containers, work in the bed, type documents in a computer or surf the internet. This will dramatically reduce the family members or healthcare providers' work load and stress.

Abstract: A system and method for generating electricity by an inflated moving wheel for transportation devices is disclosed. In accordance with embodiments of the present disclosure, an electricity generating wheel may include an flexible inflated tire, a wheel rim, a central shaft, an electricity generator is installed inside of the inflated tire; the electricity generator may include an outer ring and an inner ring and multiple springs; the inner ring and outer ring may comprise multiple piezoelectricity generators (or other types of electricity generators), the springs connect the outer ring and the inner ring electricity generators and keep the outer ring in contact with the inner surface of the inflated tire. The weight and load of the transportation devices compresses the inflated tire, imposes compression force on the springs, the springs pass such compression force on the electricity generator, the electricity is generated, significant amount of energy is recovered and reused.

Abstract: A new electric cooking system is described. This cooking system can be installed on the conventional residential electric ranges. The cooking system contains an electric burner, a cooking pot, a ceramic base plate and a thermal insulation sleeve. The electric burner has a vertical heating structure and two terminal mounting legs, the cooking pot has an inward open slot to host the vertical heating structure of the electric burner; the ceramic base plate is installed on the surface opening of the electric range where the dip pan and electric burner is located. The thermal insulation sleeve is made of the non-flammable fibers or ceramic materials and placed around the side of the cooking pot to prevent the heat lose. Almost 100% of the heat generated by the burner is absorbed by the cooking content and the energy efficiency is about 3 times of the conventional cooking system.

Abstract: A tonsillith removing device for use in removing tonsillith and other undesired matter from a user's tonsil crypts is described. The device comprises a suction channel element and a suction mechanism unit. The suction force is provided by an electric fan installed in the suction mechanism unit housing. The device has a retention feature for retaining the sucked tonsillith and undesired matter. The suction channel element can be easily detached from the suction mechanism unit and the retained tonsillith and undesired matter can be cleaned.

Abstract: A new type of solar cells and light detectors are proposed by depositing high Tc black, ceramic type superconductor on a clean surface of a p-type or n-type semiconductor. A Schottky barrier is formed at the interface of the two materials. In a preferred embodiment, the superconductor is YBa2Cu3O7-L and the semiconductor is any one of the p-type Si, n-type Si, p-type GaAs and n-type GaAs. This type of solar cells will potentially have much higher solar energy conversion efficiency than conventional solar cells due to the strong and very wide absorption range of light frequencies. This type of light detectors will have much higher detection sensitivity than conventional light detectors.
