Abstract: A headphone ear cup holds the transducer. This patent focuses on applying tone wood porting theory to the headphone cup. Simply put, tone wood theory states that certain woods provide a tonality to the music. The practice of speaker porting has been in use for many years to extend the bass response of a speaker. By combining tone woods with porting, a more musical presentation created than by using a polymer or metal cup.

Abstract: A computer controlled laser based profiling system for accurate equipment positioning. In one embodiment the profiler is used in combination with a vehicle automated guidance system for guiding a vehicle and equipment secured to a vehicle for removing of road markings. The computer controlled profiler detects the position of one or more grinding, grooving, rumbling heads in the X, Y and Z position. A controller and one or more actuators are manipulated in response to ground markings visible in the field of the laser.

Abstract: A thermoplastic extrusion vehicle for continuous processing of thermoplastic material used for applying lines and stripes to a roadway. Heated oil from a burner is directed to a common reservoir having a section for oil distributed to the extremities of the vehicle and a main section for heating of melting kettles; the common reservoir having a divider wall capable of maintaining two different temperatures within the reservoir. A programmable logic controller displays and records the mil thickness of lines that is calculated according to the volume of material consumed at the rate of application based upon the speed of the vehicle.

Abstract: A self-rotating device for cleaning with ultra-high water pressure having a base supported by front and rear wheels with a handle extending therefrom. A spray bar assembly with a plurality of nozzles constructed and arranged to cause rotation of the spray bar through fluid discharge is mounted beneath the base. A hydraulic pump is positioned with spray bar and coupled to a reservoir mounted on the handle. The hydraulic pump is rotated by the spray bar assembly, causing hydraulic fluid to recirculate through the reservoir, wherein an adjustable flow valve permits control of the spray bar assembly rotation speed.

Abstract: A grinder truck with a computer controlled profiler in combination with a vehicle automated guidance system for guiding a vehicle and equipment secured to a vehicle for removing of road markings. The computer controlled profiler detects the position of one or more grinding, grooving, rumbling heads in the X, Y and Z position. A controller and one or more actuators are manipulated in response to ground markings visible in a camera field. A remote controller allows an operator to control grinder heads individually, and allows for precise adjustment based upon an operator's visual inspection.

Abstract: A headphone ear pad couples the headphone cup, that holds the transducer, with the listener's ear. Ear pad patents typically focus on materials usage, comfort, or sound isolation. This patent focuses on the ear pad as sound delivery mechanism with the ability to alter the manner in which sound is perceived by the listener or other receptor. This is accomplished through the conical shape of the pad, multi-walled structure, incorporation of sound wave disrupters, and pressure ventilators.

Abstract: The present invention relates generally to an environmentally sensitive mobile cleaning system; and more specifically relates to a holding tank that includes at least one internal bladder for high or ultra-high pressure mobile cleaning apparatus. The holding tank with internal bladder works in combination with a mobile pressure cleaning apparatus for cleaning surfaces while minimizing water usage and containing contaminants before they enter a storm water drain system.

Abstract: The present invention relates generally to an environmentally sensitive mobile cleaning system, and more specifically relates to an orbital spray bar head for high or ultra-high pressure mobile cleaning apparatus. The orbital spray bar head works in combination with a mobile pressure cleaning apparatus for cleaning surfaces while minimizing water usage and containing contaminants before they enter a storm water drain system.

Abstract: The present system relates to a water and debris recovery system for a water blasting device or water demolition system suitable for mounting upon the frame of a mobile vehicle for easy transport and use. The system includes a liquid reservoir connected to a high pressure fluid pump for directing ultra-high pressure water through a blast head to remove the coatings or markings from a surface. The blast head includes a shroud which surrounds the blasting area to at least partially contain the water and debris dislodged from the surface. A vacuum pump is secured to the shroud with the vacuum passing through a cyclone type separator allowing the water and debris to settle to the bottom portion of the cyclone. A mud type pump is then utilized to transfer the collected water and debris into an open top tank.

Abstract: A system for removing paint and other coatings from hard surfaces is mounted on a truck for over-the-road travel. The truck bed carries a high power vacuum pump, a self propelled tractor with an attached blast head, a liquid reservoir, a sump or vacuum tank, and a ramp for loading the tractor. The reservoir is connected to a low pressure pump that transfers water to the high pressure pump. The high pressure pump is connected to the blast head by a high pressure hose. A vacuum hose is connected to the sump which has an internal enclosure for separating the waste materials from the liquid for easy dumping of semi dried materials.

Abstract: Briefly, disclosed is an articulable arm particularly suited for mobile systems utilized to remove coatings from marked surfaces with high pressure liquid. The mobile systems generally employ a liquid reservoir connected to a high pressure pump for directing ultra high pressure water through at least one blast head mounted on a front portion of a mobile self-propelled vehicle. A vacuum reservoir and vacuum pump may be utilized to recover the water and debris from the surface. The arm permits an operator to easily maintain alignment of the blast heads to the surface markings being removed. After marking removal the arm permits the blast heads to be raised to position suitable for inspection and/or vehicle transport.

Abstract: Disclosed is a cleaning system for removing coatings from a hard surface by high pressure liquid. The system employs a combination liquid and vacuum reservoir connected to a high pressure pump for directing ultra high pressure water through a blast head mounted on a front portion of the vehicle. The cleaning system is preferably mounted on a single truck with a single prime mover. The drive-line of the vehicle is constructed and arranged to operate in two distinct modes, e.g. a transport mode and a work mode. In the transport mode, a first transmission coupled to the rear portion of the prime mover delivers torque from the engine to the rear wheels of the vehicle. In the work mode, the prime mover is utilized to mechanically drive the bed mounted equipment as well as provide motive force in the form of mechanical-hydrostatic transmission to propel the system at a speed suitable for marking removal.

Abstract: A transportable holding tank for containing clean water and for accepting waste from a stripe removal system. The holding tank is carried on a flatbed vehicle and requires less deck space, thus effectively increasing the cargo-carrying capacity of the vehicle compared with that available if the vehicle were carrying a conventional round or elliptical holding tank. Construction of the tank enables the holding tank to withstand a partial vacuum imposed for pumping waste into the tank. Hooks secured inside of the tank permit a bag for separating solid waste from liquid waste for easy disposal of semi dried materials.
