The present invention relates to: an apparatus and system for detecting a road surface condition, wherein the road surface condition is determined through a sound signal; and a method for detecting a road surface condition by using same. The apparatus for detecting a road surface condition according to the present invention comprises: a sensor unit which is installed on a road and measures a sound signal generated according to a moving of a moving object on the road; and a control unit which distinguishes the sound signal measured by the sensor unit into normality or abnormality and determines, in case of the abnormality, the road surface condition including at least one of rainfall (wet), frozenness (icy), slush, and snow cover (snowy) so that a quick and accurate action corresponding to the road surface condition of a specific section can be made from a distanced place.

A fluid deposition system is provided. The system comprises one or more electronic processors, and one or more electronic memories each electrically connected to at least one of the one or more processors and having instructions stored therein. The processor(s) is/are configured to access the memory or memories and execute the instructions stored therein such that the processor(s) is/are configured to: determine whether one or more predetermined criteria are met for initiating deposition of fluid onto an area of interest; when it is determined that the criteria is/are met, determine one or more operating parameters of the fluid deposition system to use in the deposition of the fluid onto the area of interest; and following the determination of the operating parameter(s), generate one or more electrical signals to cause the fluid to be deposited onto the area of interest in accordance with the determined parameter(s).

A granular product dispenser is provided for residential or commercial use to spread salt/ice melt on walkways, drive-ways, and paths during the winter. Operation of the dispenser will be controlled through the use of an interactive website that will allow a user to turn the device ON/OFF wirelessly. Unlike current handheld dispensers, this device is intended to be placed on a porch or mounted along a path/driveway and controlled without manual operation. The dispenser includes an enclosed hopper to store melt product, a series of motors to control the flow and distribution of this product, and all electronics necessary to control the dispenser system.

In general, one aspect of the invention relates to an apparatus comprising: a vertical support member pivotally mounted to any one of a wheel axle, chassis, or landing gear at a first terminal end and coupled perpendicularly to a horizontal member to an opposing terminal end; said horizontal member dimensioned with a first plurality of linear dispensing nozzles oriented towards a bottom portion of at least one wheel, and a second plurality of linear dispensing nozzles oriented towards a top portion of a driving surface, wherein the first and second plurality of linear dispensing nozzles are each fed by an air or fluid line that diverges from a single air or fluid line in operable communication with an on-board air-pressure unit; said vertical support member and horizontal member configured to extend into a down-right position electro-mechanically at the first terminal end, wherein the first plurality and second plurality of linear dispensing nozzles is positioned less than 24 inches from the bottom portion of at least one wheel and the top portion of the driving surface, wherein activation of the vertical support member and horizontal member extending into the down-right position and deployment of pressurized air or fluid from the first and second plurality of linear dispensing nozzles.

According to various embodiments, an electronic device for classifying a road surface using a sound signal and a road surface classification method using the same are disclosed. In addition, a device and method for managing a road surface through road surface classification are disclosed. Meanwhile, a method for installing an infrastructure for implementing a road surface classification method is disclosed. Other various embodiments are possible.

The invention generally relates to a surface treatment distribution apparatus and spray assembly apparatus method capable of applying a variety of surface treatments, for example mastic surface treatments, to a variety of highways, roadways and other asphalt surfaces of variable shapes and sizes. The invention generally includes a tank, pumps, operator station, control inputs, filter assemblies, spray bar and self cleaning spray tip assemblies. Each spray tip assembly includes a self cleaning functionality whereby the operator may remove any debris or clogging material from one or more spray tips with a pneumatically actuated plunger located in the spray tip assembly that acts to force the debris or blockage out of the spray tip. The plunger retracts after actuation and the spray tip assembly is then ready to resume spray operations as desired by the operator.

An ice melt system for melting accumulated ice off of a surface includes a reservoir which has an outer wall and is hollow. An ice melting solution is stored in the reservoir. A pump is in fluid communication with the reservoir for selectively pumping the ice melting solution out of the reservoir, and a piping is fluidly coupled to and extends away from the pump. A plurality of dispensing assemblies is fluidly coupled to the piping and is positioned adjacent to a surface to be treated. Each dispensing assembly of the plurality of dispensing assemblies comprises a nozzle which is in fluid communication with the piping for dispensing the ice melting solution. The nozzle is orientable such that the nozzle is configured for dispensing the ice melting solution over the surface to be treated.
