Automobile or vehicle proximity sensor and warning display mounted on outside rear view mirror

РЕФЕРАТ

The automobile proximity sensor and warning display is mounted on an outside rear view mirror of a vehicle. A flat base plate, adhered to the outside mirror, coacts with a removable body on a front side of the base. The battery powered system includes a proximity detector, responsive to approaching vehicles, generating an alarm signal sent to a lighted display. The body may have a removable mirror. The body may be coupled to the base by complementary coupling sub-systems or an insertable body portion coacting with a shelf on the base wherein a depressible tab is sized to fit within a shelf orifice. As a power saver, an accelerometer detects motion and a timeout circuit turns OFF system power when no motion is detected for a predetermined period of time.

The power circuit conditions and alters the battery voltage and current and supplies power to the various electrical components in electrical system 100. A transmitter--receiver system 116 generates a detection signal 117 and receives the bounce back or reflected signal 119. These TXR units 116 are known to persons of ordinary skill. Logic circuit 114 not only controls transmitter--receiver 116 but also receives signals from transmitter--receiver circuit 116. A signal conditioning circuit SC1, designated as SC unit 118 conditions the signals to and from and between transmitter--receiver 116 and logic circuit 114. Upon the presence of an alarm signal generated based upon the reflected signal 119 and the transmitter receiver 116 and the logic circuit 114, logic circuit 114 issues a command to illuminate display 124. Signal conditioning circuit SC2 designated as SC unit 120 conditions the signals to and from display 124. The illuminated display may show a car or made indicate by blinking or other colored or bright light signal 125 to the driver. Display 124 in one embodiment is light-emitting diode or LED 122. To turn ON and OFF the system, as an option, the sensor and display system may include a switch 112. In one embodiment, switch 112 is a manual switch which may be associated with the depressible tab 95 discussed above.

FIG. 15 diagrammatically shows that battery 45 may be placed in base unit 80. Further, the generally flat face 94 of body 92 may have a flat faced mirror surface. Optionally, body 92 may include the convex or concave mirror sections as shown in connection with FIG. 7C. Further, rather than a flat face mirror 94 shown in FIG. 15, the body may carry a concave or convex mirrors shown in FIG. 7B.

FIG. 16 diagrammatically shows that outboard surface 94 of body 92 may be covered in whole or in part by solar cells 150. FIG. 16 also shows that the battery 45 may be placed in the body 92 rather than in the base 80.

FIG. 17 diagrammatically shows that removable body 92 may include the sensor panel 152 which is part of the transmitter--receiver 116. Further, base 80 may include the lighted display 154.

FIG. 18 diagrammatically illustrates the automatic OFF as well as the optional solar cell rechargeable battery system. Abbreviations identified in FIG. 18 follow. Accel is an accelerometer; Ckt is a circuit; SC is a signal conditioner; pwr refers to a power unit; sys pwr cntl is a system power control signal applied to system ON-OFF switch 112; sw is a switch; btty is a battery; and txr is a transmitter-receiver; and pwr convert is a power converter which converts the energy from the solar cells 300 into a voltage and current to charge battery 45. The illustration of the battery 45 refers to one or more batteries. Optionally, electrical circuit 100 can include solar cells 300. The energy from solar cells 300 is converted by power converter 302 and the resulting power or energy is applied to battery 45.

With respect to the automatic OFF system, circuit 100 includes accelerometer 404 and a timer 402 which components are generally included with or on the logic circuit chip 114. The accelerometer 404 is always supplied with power ON. Master system switch 112 has a control input such that when the control signal, called the "system power control signal," is applied at the switch control input, switch 112 turns ON the power circuit 110 and activates not only the logic circuit 114 but also transmitter--receiver 116. In the presence of an oncoming vehicle and a proximity alert from unit 116, lighted display 124 via LED unit 122 is activated by the logic circuit. In this manner, the energy from battery 45 is presented to the primary sensory electronics only when the vehicle is in motion. Accelerometer 404 generates a motion signal only when the vehicle is in motion.

Timing diagram in FIG. 19 is discussed in connection with the automatic OFF electronic system shown in FIG. 18 (the solar recharge sub-system being optional). At the time T0, the system is stable, the vehicle is not moving and the system is generally powered is OFF. The accelerometer 404 is always ON but draws little battery power. A limited portion of the logic circuit is also always powered ON to be activated fully ON when the acceleration sensor circuit 404 goes ON. When the vehicle begins to move at time T1, the system automatically goes ON as shown by the system power timeline in FIG. 19. Logic circuit 114 reacts and turns ON the power switch in response to this motion signal from accelerometer 404. At time T2, the vehicle stops and the signal from accelerometer 404 changes state. In the illustrated embodiment, the signal goes low. Also at that time, the timer 402 is activated ON and the timer count is started. Timer 402 stays ON and counts until logic circuit 114 detects the presence of a motion signal from accelerometer at time T3. This new motion signal resets the timer 402 and the timer signal goes low or OFF. At time T4, the accelerometer turns OFF the motion signal and the timer is activated ON again. At time T5, the accelerometer indicates a motion, and the timer is reset and goes low--OFF. At time T6, the accelerator determines that the vehicle is no longer moving and the timer signal goes high--ON and is activated into a counting state. After a predetermined period of time, such as 10 minutes, the timer reaches the count threshold (the timer counts up or counts down to the programmed threshold) and at the end of the count, the timer changes state (goes low or OFF) and this causes generation of a system power OFF signal applied as a system power control signal from logic circuit 114 to be applied to master system switch 112. In this manner, the energy in battery 45 is saved because the transmitter--receiver is turned OFF as are other major components. The timer's predetermined period of time can be changed based by the designer of the system.

The claims appended hereto are meant to cover modifications and changes within the scope and spirit of the present invention.
