  • Patent number: 5028908
    Abstract: An auxiliary control circuit for controlling taillights, especially the brake light and turn signal lights, of a vehicle is provided. The circuit is designed to function such that, when the brake of the vehicle is applied, the brake light blinks continuously for the length of time that the brake is applied. At the same time, the turn signal lights simultaneously blink in an alternating fashion for enhancing warning effect. When the brake is applied and the turn signal switch is actuated for the purpose of providing a turning indication, the brake light and the turn signal lights work independently in the usual manner.

  • Patent number: 5028907
    Abstract: An alarm system for indicating improper towing of a vehicle having a standard transmission may embody up to two control switches in series electrical communication which are operable to activate a warning light and/or buzzer mounted within the interior of the towing vehicle. When towing a four wheel vehicle, it is desirable to make sure that the steering is not locked and also that the vehicle is not in gear. The first control switch comprises a normally open toggle switch which closes to activate the alarm circuit when the ignition switch is in the locked or not-turned-on position. The second independently operable control switch is fluid pressure activated and is opened in response to the detection of oil pressure resulting from the towed vehicle being in gear.

  • Patent number: 5025245
    Abstract: An auxiliary pedestrian crossing warning signal system for use in automobiles equipped with a main signal system including front and rear, left and right amber turn indicator lamps incorporates an alternating flasher into the main signal system via a relay to provide communication between a driver and a pedestrian in order to reduce vehicle-pedestrian collisions. An automatic shut-off timer is connected to the relay circuit for controlling the duration of the auxiliary system operation after the brake pedal is released. The auxiliary system is operated by a momentary pressure on a pushbutton switch mounted in the dashboard and by the application of pressure to the vehicle brake pedal, so that the auxiliary system operates only when the pushbutton is energized and the vehicle is stopped. In addition to the in-dash indicator lights, a pair of indicator lights can be mounted beside the pushbutton switch as an additional indication that the auxiliary system is in operation.

  • Patent number: 5019800
    Abstract: The foregoing and additional objects are obtained by the oil measuring system according to the present invention. A first oil level measuring device is in fluid communication with the oil pan and generates a first signal indicative of the oil level within the first measuring device. A second oil level measuring device is also in fluid communication with the oil pan and generates a second signal indication of the oil level with the second measuring device. An imaginary line passes from the second measuring device, through the middle of the oil pan, and to the first measuring device. Also provided is a means for indicating the oil level in the oil pan in response to the first and second signals. Accordingly, the oil level may be checked without using a standard dipstick. Further, the present system is effective regardless of the tilt of the engine.

  • Patent number: 5015991
    Abstract: An alarm system which signals to the driver a first alarm whenever he opens a vehicle door and the selector lever of an automatic transmission is not in its full park position. The system signals to the driver and also to persons external to the vehicle a second different alarm whenever, in addition, the driver leaves his seat and the selector lever is not in its full park position or the parking pawl fails to properly engage the parking gear even though the selector lever is in its proper park position. A manual switch may be operated to selectively disconnect the alarms, with an automatic operator being provided to close this switch should it accidently be left in its open condition.

  • Patent number: 5012222
    Abstract: A sensor assembly for a proximity warning device for protection of a curbside parked vehicle, particularly from potential impact damage from another vehicle parking in an immediately adjacent curbside space, is pivotally mounted in a housing adapted to be mounted on a bumper of a vehicle and includes a relatively heavy body having a lighter elongated feeler element affixed to it and projecting upwardly substantially above the housing. The pivotal mounting permits the sensor assembly to oscillate toward and away from the vehicle. The location of the pivotal axis is so selected that, when the housing is affixed to a bumper of a parked vehicle and the sensor assembly is influenced only by gravity, the sensor assembly assumes a neutral orientation in which the feeler element is substantially vertical regardless of whether the surface on which the vehicle is parked is horizontal or inclined in the lengthwise direction of the vehicle.

  • Patent number: 4996522
    Abstract: A folding electronic device comprises a body and a cover member, rear walls of which are rotatably coupled with each other by hinges. When the cover member is closed, the rear wall of the cover member is positioned rearwardly beyond the rear wall of the body while the lower end of the rear wall of the cover member is positioned downwardly beyond the upper end of the rear wall of the body. A clearance defined between the rear walls of the body and the cover member is blocked by a closing member which is provided in the body. A spring is mounted on the closing member to rearwardly urge the same. Due to the urging force of the spring, the closing member is in contact with the rear wall of the cover member when the cover member is closed and when the same is opened by, as well as when the same is being opened/closed.
