## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electronic fishing lure, and more particularly to an electronic fishing lure that utilizes onboard circuitry to control one or a series of light (multicolor/mono color) sources so as to enhance the fishing lure's color and visibility for all light conditions a user may encounter during fishing.
2. Description of Related Art
Electronic fish lures employing a source of illumination to attract fish are known in the prior art as is evidenced by virtue of the teachings and structure contained in the U.S. Pat. Nos. 2,536,408; 4,437,256; and 4,669,213.
Although these prior art meet their specific needs, in most prior art, there is no effective controllability over turning the illumination source on and off, or changing its the lighting mode. The lighting mode cannot be readily switched; thus, the fish lure appearance cannot be easily changed based on the fly.
Prior art published in recent years provides means to control illumination color and intensity. By way of example, U.S. Pat. No. 7,707,764 to Osburn discloses a light emitting fishing lure, where the illumination source is turned on when the fish lure submerges into the water and is turned off when the fish lure is taken out of the water. Similarly, U.S. PreGrant Publication No. 2010/0175304 to Barmore discloses a fish lure including an electrical unit that can control illumination and sound emissions. U.S. PreGrant Publication No. 2009/0007480 (WO2005084431A1, EP1725092A1) to Braun discloses a fishing lure and a system for operating and controlling said fishing lure. The fishing lure contains a microprocessor and is controllable via a switch on the lure or a remote control, which can be used to select various operating modes such that the lure can produce any movement, desired color, or pattern of colors, to emulate the body of a desired bait fish. Braun discloses the use of a remote infrared transmitter to change the operational modes of the fish lure. Likewise, U.S. PreGrant Publication No. 2006/0010763 to Podlewski et al. discloses a programmable fishing lure containing an onboard microcontroller that is controllable via a switch on the lure or a remote control. The lights and sound devices of the Podlewski fish lure can be controlled using control firmware in an on-board microcontroller, with programming signals being input through an inductor USB port. These prior art devices include complex control interfaces for activating or changing the functions of the fishing lure.
Our present invention is distinguished from these prior art in that our present invention has control mechanism, switch mechanism, and charging mechanism all multiplexed into a pair of electrical contact points. The microcontroller controls lighting mode in response to simple signals received at the electrical contact points, either by a user touching the contact points, or by immersing the lure in water. Furthermore, our present invention provides solution to other aforementioned problems, such as recharging the battery.
SUMMARY OF THE INVENTION
The primary object of the present invention is to enhance fishing lure's color and visibility by one or a series of light (multicolor/mono color) sources with an onboard controller and an effective way of configuring the color and light intensity of such light sources.
Another object of the present invention is to let the user to be able to turn on and turn off the light of fishing lure.
Another object of the present invention is to let the user have the control to switch various lighting mode, such as brightness, color, flash mode and etc.
Another object of the present invention is to have the switching mechanism, controlling mechanism, and charging mechanism are all multiplexed into two electrical contact points such that there is no need for extra charging port or switch to control the light mode, switch power on and off or charge the lure through.
A yet another object of the present invention is to provide a safe and effective charging mechanism.
The present invention utilizes an onboard circuitry to control one or a series of light (multicolor/mono color) sources so as to enhance fishing lure's color and visibility for all light condition a user may encounter during fishing. For instance, during low light murky fishing, an angler can turn the light intensity up to a more penetrating color. While under sun lit clear water or dealing with spooky species in the dark, an angler can simply turn the light off or with turn to a low level setting. The light switch on/off and lighting mode or sequence can be controlled by on an on board circuitry.
The present invention provides all the controller unit, power source, light source in a sealed translucent housing. The switching mechanism, controlling mechanism, and charging mechanism are all multiplexed into two electrical contact points, that most lure uses as eyelets to connect the fishing hooks. No extra charging port or switch is needed to control the lighting mode, switch power on/off or charge the lure through.

DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 is a perspective view showing the external appearance of a fish lure 10 of the present invention. As with many existing lures, the lure has a leading lip L with an eyelet A for attaching to a fishing line. The fish lure has two electrical contact points, eyelets 11 and 12. The switching mechanism, controlling mechanism, and charging mechanism are all multiplexed into these two electrical contact points 11 and 12. No extra charging port or switch is needed to control the lighting mode, switch the power on/off or charge the battery inside the fish lure.
FIG. 2 is an example schematic diagram of one implementation of the present invention showing the controller unit, power source, and light sources (or illumination means). All these electronic components are contained in a sealed waterproof compartment forming the body of the fishing lure 10. The example controller unit is a microcontroller 20, which may be a Microchip model PIC10F20SOT in one of the embodiments. Other microcontrollers or application specific integrated circuits may be used for the control circuitry, as is known in the art. The light sources (illumination means) including a plurality of different colored lights 30 which may be light emitting diodes (LEDs) or any other source of light of primary color (red, blue, and green) which are electrically connected to the microcontroller 20. The lights can be individually controlled by the microcontroller 20. In an embodiment where three LEDs of primary color are used, the three LEDs are closely positioned such that the combined emitted light in can produce different colors and intensities by altering the output of each individual LED. The adjustment of each LED 30 can be controlled by the pre-programmed timing sequence stored in the microcontroller 20. Therefore, an angler can turn the light intensity up to a more penetrating color during fishing in murky water. While under sunlit clear water or dealing with species that live in the dark and are easily spooked, the angler can simply turn the light off or turn to a low level setting. In one of the preferred embodiments, the LEDs 30 may be LED-RGB -5 mm model. The power source 40 including at least one rechargeable battery is electrically connected with microcontroller 20 and light sources (illumination means) 30. In one of the embodiments, the chargeable power source 40 may be a lithium polymer rechargeable battery (LIPo 3.7V). The advantages of lithium polymer design over the lithium-ion design include potentially lower cost of manufacture, adaptability to a wide variety of packaging shapes, and lighter weight. The embodiment further includes a field effect transistor 50, which is N-type metal-oxide-semiconductor-field-effect transistor (N-MOSFET) in FIG. 1.
In addition to their normal function for connecting the fishing lure to a line, the eyelets 11 and 12 function as the electrical contact points where the switching mechanism, controlling mechanism, and charging mechanism are multiplexed into. The physical contact points are electrically connected with the power source 40, and the microcontroller 20. When the fish lure submerges in the water or is touched by hand, the circuit between contact points 11 and 12 is completed; the contact points 11 and 12 become of the same electrical potential allowing current from the power source 40 to travel to the LEDs 30 and microcontroller 20. The completion of circuitry also activates microcontroller 20, which can then execute appropriate operations in response to a signal sent out from contact points 11 and 12, to control different aspect of the light pattern including light color, intensity, etc. according to pre-programmed timing strategy/sequence.
The lure does not have to light up as soon as it hits the water like most of the electronic fish lures in the prior art. Instead, the present invention can include timing delay, allowing the fish lure to wait for a period of time before activating the lights. Such a timing strategy during that period of time gives the user a window to control different lighting aspects.
An example of a timing strategy (sequence) for color and illumination including timing points and aspects of function is presented in the timing diagram in FIG. 5.




In the timing diagram in FIG. 5, each of t0, tl and t2 represent a distinct point in time. t0 is the moment in time when contact points 11 and 12 become of the same electrical potential; typically, when the fish lure submerges into the water. tl, t2, and later points to are time points defined by the control circuitry for other purposes. W in FIG. 5 represents the control window. Each different window corresponds to a different time interval, for example, w1 corresponds to the time interval between t0 and tl and w2 corresponds to the time interval between tl and t2, and is assigned a different aspect of the function.
For example,
t1=1s; t2=1.5s; . . . .
w1-> change color; w2-> change light intensity and so on . . . .
When the fish lure submerges in water for 0.8 second and is then taken out of the water (or contact points 11 and 12 are touched by hand and held for 0.8 second), the lure will change its color to the next defined color. When the same happens for 1.3 second, the lure will change its light intensity to its next defined level.
The multiplexing feature of the present invention is preferably implemented as programming in the control circuitry. An example of pseudo-code for such programming is shown below:

in the water

A safe and effective charging mechanism may be in one embodiment a solar cell or, in another embodiment an electrical circuit, a schematic diagram of which is disclosed in FIG. 3 wherein a recharging mechanism is presented. In this embodiment, charger 60 is used to recharge the battery 40 which may be model MCP7383SOT. The electrical contact points 11 and 12 are used as charge terminals. A rectifier diode as electric barrier is used to prevent current from flowing from one contact 11 to the other 12 so that the electricity can only flow one way, the direction of the charger. By adding an electronic component barrier, contact point 11 and contact point 12 can be used as charging terminals.
All the components, microcontroller 20, rechargeable battery 40, light source 30, are all contained in a sealed waterproof housing.
