    Abstract: A signal lamp control system for one rear side of a vehicle receives a signal or voltage from the vehicle (near side signal) originally intended to turn on all signal lamps on that side. Responsive to that signal, the signal lamp control system either turns on all signal lamps on that side or sequentially turns on the signal lamps on that side, depending on a status of a signal or voltage from the vehicle (far side signal) originally intended to control the signal lamps on the opposite rear side of the vehicle. In some embodiments, the signal lamp control system has knowledge of the state of the other side before the near side signal transitions on.

    Abstract: Detection is made of an activated direction of a vehicular operator device capable of being activated in at least two directions. In response to activation, in a first direction, of the operator device, informing sound is generated which varies over time with a first characteristic, and, in response to activation, in a second direction, of the operator device, informing sound is generated which varies over time with a second characteristic generally opposite to the first characteristic. For example, when a right turn is instructed, informing sound is generated with a characteristic to progressively raise the sound pitch from a relatively low sound pitch, while when a left turn is instructed, informing sound is generated with a characteristic to progressively lower the sound pitch from a relatively low sound pitch (, or vice versa).

  • Patent number: 6424256
    Abstract: The present invention provides for a sensor and signal for unsafe occurrences. In the preferred embodiment, a severe braking alert system is coupled to a vehicle for notifying trailing drivers that the vehicle is braking severely. Sensors in the system detect when the vehicle exceeds a predetermined deceleration threshold value thereby causing one or more of the vehicle's existing rear lights to flash for a predetermined time period. Alternatively, a dedicated light(s) can be incorporated. The flashing light(s) alerts trailing drivers to the dangerous condition and provide them with valuable information about the vehicle's rate of deceleration. This allows the trailing drivers to apply the appropriate amount of braking power to their vehicles in order to prevent a rear-end collision. Alternative flashing schemes can also be incorporated to notify the trailing driver about the degree of severity with which the lead vehicle is decelerating.

  • Patent number: 5877681
    Abstract: A lighting system and method for broadcasting colored lights as emergency warning signals from a light source. A centralized continuous light source is coupled via a fiber optic transmission medium to an external display location such as a lens or the like located on a vehicle. The color and the relative intensity of each color is periodically modulated to alternate between at least two states such that the contrast between these alternating states is perceived by observers to be a flashing source of light with no off-time. The frequency and the duty cycle of the repetition rate of alternating between the states may be further controlled to better draw attention to the light source.

  • Patent number: 5831523
    Abstract: A vehicle light system is provided for use with a vehicle having a rear window with a periphery defined by a linear top edge, a linear bottom edge, and a pair of side edges formed therebetween. Provided is a plurality of spaced red light emitting diodes formed along the top edge of the rear window. The red light emitting diodes include a first set of diodes situated to the left of a central extent of the rear window and a second set of diodes situated to the right of the central extent thereof. In use, the red light emitting diodes are adapted to illuminate only during the actuation thereof. Finally, a brake relay control mechanism is adapted to actuate the red light emitting diodes in sequence upon the braking of the vehicle with a short delay therebetween, wherein the red light emitting diodes are actuated in sequence from the central extent of the top edge of the rear window to a side extent thereof.

  • Patent number: 5805061
    Abstract: A method and an electronic circuit are for monitoring the operation of a circuit including a plurality of intermittently powered parallel load elements, such as the flasher lamps of a vehicle. The total load current is directed through a measuring shunt resistor, and the resulting voltage across the shunt is measured and evaluated. The measured voltage initially arising across the shunt is used as a basis to establish a first voltage level for a load failure control threshold. A second voltage level greater than the first voltage level is established as a short-circuit control threshold. Then, the voltage value arising across the shunt during operation of the circuit is compared to the load failure control threshold and the short-circuit control threshold, and a load failure or a short-circuit is detected dependent upon and responsive to the result of these comparisons.

  • Patent number: 5786754
    Abstract: An electric assist steering system (10) includes a steering torque sensor (110) and an electric assist variable reluctance motor (26) operatively connected to a steering member. A motor control signal is provided in response to a value of the torque signal for control of the assist motor (26). Energization sequence of the assist motor is dependant upon the relative position of the motor rotor (38) with respect to the motor housing and stator (32). A motor position sensor (54) provides a rotor position signal to (i) a drive control circuit (150) controlling motor energization sequence, and (ii) turn signal control function (130). Turn signal control function (130) controls turn signal indicators (121) in response to the sensed motor position.

  • Patent number: 5731755
    Abstract: A U-turn indicator having a series of sequentially illuminated lights forming the shape of `U`. The indicator is for vehicles or vehicle travel paths. In combination with a vehicle, a plurality of indicators is used. Preferably, an anterior non-inverted `U`, a posterior inverted `U`, and a side laterally dispositioned `U`. In combination with vehicle travel paths, an inverted `U` indicator is used in conjunction with a conventional traffic light or the equivalent. The U-turn indicator is activated by an actuator (a operator accessible switch in a vehicle or a vehicle presence sensor in the path). The control module responds to the actuator and generates a control signal, thus sequentially illuminating the series of lights.

  • Patent number: 5694112
    Abstract: A completely solid state rotary beacon which produces a rotary beacon lighting effect without the use of mechanical components or rotating parts. The device of the present invention includes a plurality of light sources which are equicircumferentially spaced around the outer perimeter of the rotary beacon. These light sources are intermittently illuminated by an electronic controller in such a fashion that the illusion of a rotating light beacon is produced without the need for rotating mechanical components. The lighting sequence, in conjunction with the unique parabolic reflector arrangement of the present invention, create the illusion of a light source being rotated in a 360.degree. path. This effect is achieved by the present invention without the use of rotating mechanical components.

  • Patent number: 5673019
    Abstract: This invention has an Automatic Safety Turn Signal Adapter mounted on the steering shaft of a vehicle to control the flow of electricity. When the steering shaft is turned to the right or left the electric current from the vehicle battery is directed by the adapter to the electrodes that control the right or left side turn signals of the vehicle. The negative terminal of the battery is grounded to the vehicle frame. Power input flows from the battery positive pole, to the electrical apparatus of the adapter, to the turn signal lamps, to the negative grounded frame, and back to the battery negative pole, completing the electric circuit. As the current flows from the positive pole of the battery it passes through an electric circuit breaker which causes the turn signals to flash. The adapter has a switch to manually turn the turn signals off and on and a switch to manually turn the 4-way safety flashers off and on.
