Not ApplicableBACKGROUND OF THE INVENTION
The present invention relates to a radar wave and laser detection system designed and implemented for modular, safe, secure and efficient use when installed upon a motorcycle.
Many unique methods to warn a driver of the presence of speed detecting radar and laser waves are currently in use. For example, U.S. Pat. No. 4,719,462 describes a radar detection helmet to be worn by the driver. Correspondingly, U.S. Pat. No. 5,034,747 discloses a detachable radar unit for a helmet. Further, U.S. Pat. No. 5,114,060 describes a radar detector mounting apparatus for securely mounting a commercially available radar detector unit on either the handlebars or fairing of a motorcycle. Additionally, U.S. Pat. No. 5,781,145 discloses a method and operation of a permanently affixed radar detection unit in the interior of a motorcycle. Finally, U.S. Pat. No. 5,005,661 describes a method for mounting a radar speed monitor in a removable manner to a motorcycle.
Although these many implementations exist, there remain numerous improvements to the functionality, control, efficiency, and security of a motorcycle mounted radar/laser detection unit. Further, the unique operational requirements for a motorcycle driver demand increased ease-of-use of said components to ensure safe operation.BRIEF SUMMARY OF THE INVENTION

The present invention further provides additional safe, efficient, and inconspicuous operation through the implementation of a light sensitive electronic circuit within the main detection module Mu1. This light sensitive electronic circuit shall adjust automatically the intensity of the light emitting diode array Mu3 through Mu7, such that it is brighter and therefore easier to see when ambient light is high, and dimmer when ambient light is low. This provides increased safe and efficient operation of the unit such that the driver will not be distracted and forced to avert inappropriate amounts of attention in order to see the display during the day. Further, this feature prevents a loss of light sensitivity during night operation.
The present invention provides detection of microwave signals through the use of not only the internal microstrip antenna as described previously, but three external antennas as well.
The present invention further provides signal detection capabilities through the use of two external laser detection devices. These devices consist of photo-sensitive diodes which are sensitive to light waves in the region between 820 and 950 nm. As above, these diodes will be packaged such that they are resistant to water and other contaminants such as dirt.
These three external antennas, one of the type shown in
As a signal is detected in one of the three external antennas, an electrical signal travels from the antenna to a small, concealed integration unit,
The integration unit then sends these signals through separate wires, yet combined within a single wire loom, Iu2, to the main detection unit
As the physical and mental demands of a motorcycle operator are higher than those placed upon other vehicle operators, the functionality and control of a motorcycle mounted device must remain simple and efficient. The present invention provides the needed increased safety, efficiency, and control through the use of a single simple control component, manufactured and implemented such that the driver may easily control the invention without averting unnecessary attention to its operation. The control housing is depicted in
In the preferred embodiment of the present invention, the control housing of

In the preferred embodiment of the invention an individual would first install the main detection unit
Next, in the preferred embodiment, the operator will install the optional rear radar detection unit
Next, in the preferred embodiment, the operator will mount the control housing to the left handlebar of the motorcycle. The housing shall be mounted directly to the right of the handgrip such that the motorcycle driver may operate all buttons with the thumb of his/her left hand with little or no movement of the driver's hand from the handgrip. Further, the control housing shall be constructed in such a compact, thin manner as to require very little or no movement of the stock controls from their stock position. The control housing shall further be constructed with thin layers of double-sided industrial strength tape placed on the inside of brace Ch4 and housing Ch1. This tape will bond to the handlebar of the motorcycle as the housing is mounted and tightened together, thus requiring no drilling or permanent alteration to the handlebars to ensure the housing does not rotate or shift from its mounted position.
Next, in the preferred embodiment of the present invention, the operator will mount the integration unit
Further, functionality of the preferred embodiment is achieved as described previously through the use of a super heterodyne receiver configuration. As a signal is received on one of the antennas, either internal or external, an electrical signal is passed to the main detection unit electronics. As the electronics in this main detection unit determine the validity and strength of the signal, the appropriate light emitting diode will begin to blink at a rate corresponding to signal strength.
For instance, if the detected signal is found to be a weak laser signal from the rear of the vehicle, LED Mu7 will begin to blink slowly and the lower half of Mu5 will light up. If the signal strength decreases to a negligible amount, the display will return to no LEDs lit. However, if the signal increases in strength, the rate of blinking of the LED will continue to increase. The blinking rate therefore helps the driver quickly determine the strength of the incoming signal while diverting very little attention to the unit. Further, continued monitoring of the signal is automatic and requires no additional input from the user. As the indicator LEDs Mu3 through Mu7 all emit different colors, the driver is not required to read or divert attention to tiny letters or displays, as in the prior art, in order to determine the frequency of the incoming signal. As the operator becomes familiar with the color indications, only a very short glance will be necessary to determine signal frequency.
As the present invention is operated from the vehicle power source, the preferred embodiment achieves a further improvement over prior art as the user will never need to change portable batteries. Further, this voltage source allows the unit to always run as long as the vehicle is running, thus the operator is protected from inadvertently leaving power off from the system. Additionally, as the unit will never need to be removed to change batteries, and as the invention is resistant to water and dirt, it may be affixed in a semi-permanent manner. This is a vast improvement over temporary mounting methods described in the previous art as security and durability are increased.
The preferred embodiment of the present invention thus provides increased safety, security, efficiency, ease of operation, usability, concealment, and durability over prior art. Further, the present invention is universal to all known motorcycle types, requires no permanent alteration to the vehicle, and provides unimpeded operation of the vehicle while increasing visibility and effectiveness over the prior art.
