Abstract: Hearing aids are enhanced by application of liquids thereto, said liquids being solvents for organic matter, or wax, or ear canal wax. The liquids are volatile. Application of the liquids to both the hearing dome ends and the ear canal surfaces create a coupling thereof, which maintains a desired position of the aids within the ear canals.

Abstract: A piezoelectric generator is developed by providing a closed vessel within which piezoelectric powders of nanometer sizes are placed with an inert impact material and a viscous inert liquid which maintains the mixture in a cloud-like condition. A small empty space is preferably maintained in the vessel to enable free motion of the mixture when the vessel is moved. The impact material collides with the piezoelectric crystals to generate voltage pulses, and an electric current is created through one or more conductive wires in the vessel.

Abstract: Vehicle 4-way emergency flasher circuits are modified by circuit branches which enable flashing selected pairs of emergency lamps at a higher frequency or in other discernible different ways. These selected lamps become visible and recognizable as right or left turn signals while the 4-way flasher circuit is operating.

Abstract: A third light is added above the lower two rear turn signal lights of an automotive vehicle Detection hardware is included which senses when both lower lights begin flashing simultaneously due to activation of the vehicle's 4-way hazard warning system. Such detection also introduces current pulses to the third light which flashes simultaneously with the lower two lights to generate a triangular configuration of the three flashing lights. Retrofit circuitry is described to enable installing the modified triangular signal into existing vehicles.

Abstract: Potential disadvantages of the enhanced emergency hazard warning lights set forth in U.S. Pat. No. 7,352,278 are overcome by adding a lamp that beams its light rearward toward approaching traffic, is located approximately midway between and above the horizontal alignment of the rear turn signal lamps, thereby forming a triangular flashing emergency hazard warning signal that cannot be discontinued or otherwise disturbed when the vehicle's brakes and brake lights are simultaneously operated.

Abstract: Enhanced internal electrical generators are provided which include pole pieces that form air gaps flanked with conductive wire coils. Rotatable armatures supporting permanent magnets are arranged to swing or revolve relative to the air gaps such that the magnetic flux thereof is intersected by the wire coils to generate electrical voltage and current therein. These generators may be incorporated within the housing of many portable devices such as cell phones to self generate electrical current useful for operating the device or recharging its batteries or other component that stores the generated electrical energy.
