The device includes a radar system, LED lights, a microcontroller, a proximity sensor, a camera, a strobe light, an audible alert unit and a vibration unit. The device detects a speed of an on-coming motor vehicle. If the vehicle is exceeding a predetermined speed limit, the speed is displayed on the device. If the vehicle does not slow down below the speed limit within a distance detected by the proximity sensor, the camera records the vehicle while the strobe light blinks to warn the driver of the recording. The audible alert unit and vibration unit alert the pedestrian. The system may be used to relay data to a law enforcement agency.

## Background
BACKGROUND OF THE INVENTION
Various types of road safety apparel are known in the prior art. However, what is needed is a wearable pedestrian safety radar system including a harness intended to be worn by a pedestrian when traveling on a motorist roadway. The harness incorporates a portable radar detection and display device on the front and the back of the harness which is configured to detect the speed of an on-coming motor vehicle. The system allows for programming of a speed limit. If the vehicle is exceeding the speed limit, the device displays the detected speed value visible on the harness as the motor vehicle approaches the pedestrian. If the vehicle does not reduce to a speed below the speed limit, the device blinks to alert the driver and then records the data and photographs the vehicle. The device also vibrates and makes an audible sound to alert the pedestrian that a speeding vehicle is approaching. The device may be used to relay the recorded data to a law enforcement agency as a police report, to the Department of Motor Vehicle or to the Citizen Vigilant Reporting Reward Program.
FIELD OF THE INVENTION
The present invention relates to road safety apparel, and more particularly, to a wearable pedestrian safety radar system which is a harness intended to be worn by a pedestrian when traveling on a motorist roadway. The wearable pedestrian safety radar system incorporates a portable radar detection and display device configured to detect and display the speed of an on-coming motor vehicle and record and store data for relay to a law enforcement agency as a police report, to a motor vehicle registration agency or to the Vehicle or to the Citizen Vigilant Reporting Reward Program.
SUMMARY OF THE INVENTION
The general purpose of the present wearable pedestrian safety radar system, described subsequently in greater detail, is to provide a wearable pedestrian safety radar system which has many novel features that result in a wearable pedestrian safety radar system which is not anticipated, rendered obvious, suggested, or even implied by prior art, either alone or in combination thereof.
To accomplish this, the present wearable pedestrian safety radar system includes a harness configured to be worn by a pedestrian which incorporates a portable radar speed detection and display device. The a portable radar speed detection and display device includes a display case, a transparent protective cover, a speed detection and display board, a transparent radiofrequency barrier film, a microcontroller, at least one infrared proximity sensor, a camera, a battery source, at least one solar panel, a vibration unit, an audible alert unit and a micro USB port. The speed detection and display board has a radar system, a plurality of light emitting diodes, and a strobe light. When the pedestrian is on the roadway, the radar system detects the speed of the on-coming motor vehicle and transmits the data to the microcontroller. The microcontroller is disposed within the compartment of the display case. The microcontroller is in operational communication with the radar system, the speed detection and display board and a battery source. The microcontroller operates under control of software and data configured to convert said speed signal into the measured speed of the motor vehicle and to allow programming of a predetermined speed limit determined by US Department of Transportation speed limit signs in the area.
If the motor vehicle is moving at a speed in excess of the predetermined speed limit, the speed is displayed on the portable radar speed detection and display device worn by the pedestrian. The infrared proximity sensor detects the distance between the motor vehicle and the pedestrian and sends a signal to the microcontroller when the motor vehicle is within ten feet of the pedestrian. The vibration unit vibrates and the audible alert unit makes an audible sound to notify the pedestrian of an on-coming speeding motor vehicle. If the if the driver does not adjust the speed below the predefined speed limit as detected by the radar system within the distance of ten feet as detected by the infrared proximity sensor, the microcontroller sends a signal to the LED strobe light and the camera. The camera is configured to automatically record images of the motor vehicle. The strobe light blinks to alert the driver that a photo is being recorded.
The device is also configured with a license plate recognition application to recognize and store a license plate number of the motor vehicle, a global positioning system (GPS) module and geolocation application to determine and record location data, a Bluetooth® module and a Wi-Fi card to allow wireless transmission of data from the microcontroller to an external component such as a personal computer, a cell phone, a smartphone or Google Glass®. The data may be relayed by a to a law enforcement agency as a police report, to a motor vehicle registration agency or to the Citizen Vigilant Reporting Reward Program.
The wearable pedestrian safety radar system may include a transmitter harness, a panel, and a transmitter device. The transmitter harness has a plurality of adjustable straps and a plurality of fasteners. The transmitter harness is configured to be worn on a front side by a pedestrian. The panel is formed of a clear plastic material. The panel includes a camera pocket, a smartphone pocket and a transmitter pocket. The transmitter device includes a pocket radar system, a transmitter camera with a flash and a strobe light. The pocket radar system is configured to detect the speed signal of an on-coming motor vehicle, convert said speed signal into a measured speed value, to allow programming of a predetermined speed limit determined by US Department of Transportation speed limit signs in the area and to allow transmission of data. The transmitter camera with a flash is in operational communication with the pocket radar system. Upon failure of the on-coming vehicle to reduce the speed below the predetermined speed limit as detected by the pocket radar system, the transmitter camera with a flash automatically records images of the on-coming motor vehicle. The strobe light blinks to notify the on-coming driver that a photograph is being recorded. The transmitter includes a camera shutter button which enables the pedestrian to manually photograph a speeding on-coming motor vehicle. The transmitter is configured to transmit data to the existing smartphone. The data may be relayed to a law enforcement agency as a police report, to a motor vehicle registration agency or to the Citizen Vigilant Reporting Reward Program.
Thus has been broadly outlined the more important features of the present wearable pedestrian safety radar system so that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.
