These applications are directed to and further illustrate other features of the embodiments disclosed herein, and are incorporated by reference in their entirety. U.S. Patent Application Serial No. 60/41 8,122, entitled "Automatic Flushing Valve Operating Equipment Wide", filed in the first quarter of 2002. U.S. Patent Application Serial No. 60/41, No. 87, entitled "Automatic Flushing Actuator for Trough Washrooms", filed on January 12, 2002. BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a system and method for controlling fluid flow, and more particularly to a system and method for automatic brake control of flushing drive elements. [Prior Art] Some rinsing systems suffer from the effects of contamination and contamination. When the user touches a handle that allows water to flow into the accessory, bacteria may pass from one user to another. Contamination and contamination may result from hand-to-mouth, hand-to-nose and hand-to-eye contact. Understanding the presence of such contamination may result in an unwillingness to touch the handle of the fitting that has not been improved. To minimize the risk of bacterial transport, some flushing systems use a hands-free method to control water flow. In some systems, a passive sensor is used to detect the presence of a user. Once the user leaves an area, some devices use a -turning device to convert the rotation of the motor into the linear motion required to actuate the handle. In a rotary drive, the inertia of the motor shaft may cause the motor shaft to rotate past the desired stopping point, thus initiating multiple streams of water through the fitting. In addition to wasting water, this overtraveling may fatigue the rotating jaw and require a higher initial torque to initiate another rotation at the beginning of the second flush cycle. SUMMARY OF THE INVENTION The present invention is defined by the scope of the patent application. This description is a summary of some of the features of the preferred embodiments and should not be used to limit the scope of the application. The flush valve system embodiment includes a sensor, a biasing circuit, an electrical switch, a mechanical switch, and a flush valve. Preferably, the biasing circuit is constructed to bias the electrical switch when the self-sensor receives an actuation signal. Preferably, the mechanical switch is actuated when the electrical switch is closed. The flush valve is coupled to the electrical switch and mechanical switch 'to enable fluid to flow when the electrical switch is open and to help flow ' until the mechanical switch is closed. An embodiment of an automatic braking method includes receiving an actuation signal, actuating a dice switch to initiate rotation of a switching cam and opening of the valve, actuating the mechanical switch when the resected portion of the switching cam contacts a portion of the mechanical switch, and when the mechanical switch The valve is partially closed when the portion is outside the cut-out portion. Other features and advantages of the present invention will be described in conjunction with the preferred embodiments. [Embodiment] U24652 The superior over-travel braking system and method provide a user-handless system and method for controlling the flow of fluid. The preferred system and method accurately brakes the motor to the desired position. In one embodiment, the precise braking of the motor provides a larger cam surface area for the system and method to engage a contact element. Figure 1 and Figure 2 are partial cross-sectional views of the automatic flushing embodiment (10). Embodiment 100 includes a first housing or housing 1 2 that is lightly coupled to a second housing or power source, 104. Although the embodiment 100 can be reassembled to any flush valve or flushing unit without disassembling the valves or the single S, as shown, the outer casing 102 is mounted to a valve housing by a threaded opening. In this embodiment 100, the flush handle has been replaced by a plunger pin 8. Preferably, the housing 102 encloses a motor 106 in which the motor is mechanically coupled to a lever cam 1〇8 and a switch cam 112 via a gear train 110. In the embodiment 100, the lever cam 1〇8 and the switch cam ΐ2 are completely rotated one turn during the flushing cycle (36 degrees of motion, when the lever cam 1〇8 is actuated, the lever cam 1〇8 makes a lever 12 The inactive state shown moves to the action or flush state shown in Figure 2. Since the core (10) is rotated from the inactive state to the flushed state, preferably, the parabolic portion 114 of the rod ... 8 engages and moves a panel 116. It engages and moves the plunger pin 8 and the lever 120. Preferably, when the flushing cycle is completed, a tensioning device, shown as compression spring 122, biases the panel 116 against the flat portion 124 of the lever cam. In the inactive state, #12〇 returns to the inactive position 'which closes the flush valve. In ® 1, when the flush valve is closed, the rod i is in a nearly vertical position. In other embodiments, the rod 12 is in other positions. Referring to Figure 1, preferably, the motor 106 is enclosed in a housing 1 。 2. The motor 106 is mechanically coupled to a gear train 11 〇, which is shown in Figures 1 and 2 as being fixed to the housing 1 〇 2 The reduction gear train in the middle. When the material ι〇6 acts, the gear train 11〇 The lever cam 108 and the switch cam 112 rotate in a clockwise direction 'because they preferably share a common shaft 126. As the lever cam 108 rotates, the parabolic portion 114 of the lever cam 108 engages and moves the panel 116 to the right. Preferably, This movement forces the plunger pin U8 and the lever to the right to start a flush cycle and open the flush valve. Preferably, when the sensor U0 detects that a user or a condition exists, the automatic flush is activated. The sensing n 13 〇 may be a motion detector infrared detector, a body heat detector 'or any other device that converts non-electric energy into electricity or light energy to detect or measure something. Preferably, The sensing range of the sensor 130 can be adjusted, which allows the sensor 13 to be mounted at any desired position. For example, the sensing stomach 13 can be mounted away from the housing 102, as shown in FIG. Integrated into housing 1 or forming a single portion of housing 102. When sensor 13 is integrated into housing 1 or 2 or forms a single portion of housing 1〇2, a portion of sensor 13〇 or Its lens is able to ensure that the sensor 13 is monitored One of the fields of view protrudes from the outer casing 102. In the embodiment of Figure 3, the sensor lens forms an angle of about fifteen degrees with the plane 302 that is substantially parallel to one of the outer surfaces of the casing 102. Part one although this feature is shown in an alternative reassembly embodiment that does not require disassembly of the fitting (eg, it accommodates a flush handle) 'but it can also be used in embodiment 1 described herein or used in any other The flushing device is used in conjunction with. 1324652 The operation of motor 106 occurs when received as a motion signal by sensing logic or electronic device 402. In FIG. 4, there is an interface between sensing logic 4〇2 and motor braking logic 400. In this embodiment 100, an actuation signal is generated when the user leaves a field of view or when a sensor generates an electrical signal. At this stage, the 'integrated circuit pin 〇ρι 4〇4 is driven low for seven tenths of a second' and the OP2 406 is driven low for a complete flush cycle because the integrated circuit pin pl 4 〇4 and 〇p2 406 are in a low state of action, then pnp transistor Qi〇4〇8 supplies a voltage to motor ι6, which in this embodiment is an unregulated dc six volt source. The p_n_p transistor q 12 410 discharges the capacitor C14 412 and sinks the current flowing through the switch S101 414 and the resistor R3 3 416 to ground, and the p_n_p transistor Qu 418 bias represents the current sink of the n_p_n transistor q14 42〇 The device starts the rotation of the motor shaft 128, the lever cam 1〇8 and the switch cam 112. When the motor shaft 12 8 , the lever wheel 1 〇 8 and the switch cam 112 rotate, preferably, the switch S101 414 connects the pole 2 to the connection motor 1〇6 to a pole 3 of a supply voltage, and in the embodiment 1 In the middle, the switch sl1 414 is a micro switch. When the panel 116 slides down the top portion of the lever cam 丨 08, preferably, the compression spring 122 causes the lever cam 108, the switch cam 124 and the motor shaft 128 to rotate. In this state, the integrated circuit pin OP丨4〇4 is biased to a high state, and the compression spring 122 mechanically transfers energy to the lever cam 1〇8 and the switch cam 112, and the motor 1〇6 acts as a generator. The positive voltage is to the collector of transistor Q10 408 and η-ρ·η transistor qi 1 424. When the motor 106 generates electric power, the switch knob 5〇6 of Fig. 5 is released and 10, contacts & φ 502, which is wound around the cut-off portion of the switch cam J12 504 ^ when it is released, the switch 414 is coupled to the pole! Connected to pole 2, its connection: source capacitor C14 412. The electrical current initially drawn by capacitor C14 412 biases n-p-n transistor Qi 1 424 when motor 106 is effectively grounded. As a result, the kinetic energy of the 'motor H) 6 is converted into electrical energy, and the loss becomes thermal energy. Preferably, the switching cam 1 12 is configured to close the motor 1 just before the panel 1 喷 6 sprays the flat portion 124 of the lever cam 112. 6. In this embodiment 100, preferably, the faceplate 16 is not disposed on the parabolic portion 114 of the lever cam 108 during the inactive state. Preferably, the 'automatic flushing embodiment 1' may also include a brake control. Preferably, the brake control prevents the motor from overheating or damaging when the gear is stuck, the cam is blocked, or other solidification occurs. Referring to FIG. 4, the integrated circuit pin Duty 426 controls the output duration of the integrated circuit pin OP2 406. In this embodiment, an RC circuit comprising R40 430 and C15 428 controls the duration of the bias voltage of p-n-p transistor Q13 418 and η-ρ·η transistor q14 420. Therefore, the on-time of the transistor Q14 4 2 0 can be programmed to match the normal time of the flush cycle. While this embodiment is not limited to any particular cycle time or range, in one embodiment, the duration of the bias signal can range from about seven tenths of a second to about five seconds. FIG. 6 shows a second embodiment 600. As in the first embodiment 100, the actuation of the flush cycle begins when an actuation signal is received. In this embodiment 600, an actuation signal is generated when the user leaves a field of view or when a sensor produces an electrical or optical signal. In this state, the integrated circuit pin 14 602 is driven 3: Ζ 40:): Ζ is held for about seven tenths of a second. If the integrated circuit pin is in the active state, then η·ρ·η transistor Q4 6() 4 bias_source switch or n b b body Q5 606 ' is supplied to the motor 6〇2, and The rotation of the initial motor shaft i28, the trunk cam 108, and the switch cam 112. When the motor shaft 128, the lever wheel 1〇8 and the switch cam 112 rotate, the single pole single throw switch s· _ connects the motor 106 to the power source. When the field panel 116 slides down the top portion of the lever cam 1〇8, the compression spring 122 preferably urges the motor 1〇6, the lever cam 1〇8 and the switch cam ΐ2 to rotate. When the horse 106 is biased by the compression magazine 122, preferably, a switch knob 506 is released and slidingly contacts the convex surface 5〇2, which is surrounded by the cut-away portion of the switch cam i12. . Once the switch knob 5〇6 is outside the cut-out portion 504, a pulse from the integrated circuit 61〇 substantially grounds the motor 106. Preferably, the switch 414 is turned on to initiate the motor shaft brake logic. The logic of the 〇 is done by software and/or hardware in the integrated circuit. Preferably, the 'integrated circuit' is just flat with the panel 116 engaging the rod cam 112. Turn off the motor i 〇6 after 卩. Preferably, the panel 1丨6 is not disposed on the parabolic portion 丨丨4 of the lever cam 丨〇8 during the inactive state. Preferably, the automatic flushing embodiment 6 can also include a brake control. Preferably, the brake control prevents the motor from overheating or blocking when the gear is stuck, the cam is blocked, or other solids are occurring. Although the control has many configurations, in one embodiment, the grounding of the interrupt motor 1〇6 is controlled by an electronic, mechanical, and/or electro-mechanical switch that is actuated by a control signal. Preferably, the duration of the control signal is programmed to be approximately equal to the duration of the 12 flush cycle. As shown in FIG. 7, when a 702 receives an actuation signal: the method begins to 'watch the first step in the action step by converting non-electric energy into electricity or light two: 13° or other device, wood, nine 彳 彳 5 Field or measuring something: When the standby-electronic switch is actuated, the electronic switch operates the motor 1〇6 to rotate the gear train 11 〇, the door lag & , the 凸轮 cam 112 and the lever cam 1 〇 8 The cam 1〇8 is used to mate the lever 120 to the action or flush state. In the action step, the electronic switch turns off one of the motors 1〇6. Preferably, the switch cam 112 is fully rotated to engage the switch knob & 506 for coupling via the switch μ4. Power is supplied to the motor 106. At action step 706, when the switch knob 5G6 contacts the lower surface of the cut-out portion 5() 4, the mechanical switch provides power to the horse it 106. Preferably, when the switch knob 5〇6 is not in the cut-away portion (10), the mechanical switch turns off the power of the motor 1〇6. Preferably, power is turned off just before panel U6 engages flat portion 124 of lever cam 112. When the panel 116 engages the flat portion of the lever cam 1 〇 8, the lever 12 〇 returns to the inactive position and the flush valve closes at action step 708. It is also preferable that the panel 1 16 is not disposed on the parabolic portion 1 14 of the lever cam 1 q §. The above systems and methods provide an easy to install, reliable flushing device' that does not require direct intervention by the user. The system and method can be operated using one or more batteries, or connected to an external power source or to any other type of power source. Preferably, the integrated or separate component can be attached to an automatic flushing unit or reassembled to any flushing unit or commercial or residential flush valve. 13 1324652 Preferably, the overtravel braking system and method can apply a braking force to a motor to prevent the cam from exceeding a desired position. While the system and method have been illustrated by the embodiment of cams and gears, many other alternatives are possible. This alternative includes an automatic actuator, a solenoid drive system, and any other system that uses a flush valve for fluid dispensing. Moreover, the control logic is not limited to circuitry because the overtravel braking system and method also encompasses other control logic, including, for example, optical logic. Many other alternative embodiments are also possible. For example, a system 盥 method directly connects a ground control switch to an integrated circuit. In these alternative embodiments, the integrated circuit 〇P2 4〇6 in Fig. 4 is in a high state, which is directly coupled to R38 432 coupled to the n-P-n transistor Q14 42A. Moreover, more or fewer components may be added or removed from the above embodiments. Another example can be directly coupled. Electrical, optical or mechanical switches (such as microswitches) to the post pins or push rods' to sense the position of the plunger pin/push rod and the need to initiate braking or braking or circuit disconnection. Although some preferred embodiments of the invention have been described, it is to be understood that 'more embodiments and examples are possible' and are within the scope of the invention. The foregoing detailed description is to be regarded as illustrative and not restrictive, and the scope of the invention is defined by the scope of the claims.
