  • Patent number: 6535113
    Abstract: An electrical tell tale system for trailers that consists of a unique tell tale monitor which is light weight which houses different colored light emitting diodes which define each individual trailer circuit. The tell tale monitor has an attached modular cable and modular plug which is connected by a modular socket to the main control unit. The main control unit has two protruding leads which are connected in series with the vehicles trailer wiring harness by connectors. The system works by scanning the trailer signals passing through the main control unit and specially set, wound resistive current sensing coils, which close a reed switch at the correct current which in turn sends a low voltage signal through the modular connection and through the modular cable to the tell tale monitor which will illuminate a certain light emitting diode to notify if the trailer circuit is operational.

  • Patent number: 6437687
    Abstract: An alarm assembly is provided alerting the operator through one of a visual, audible, or tactile signal, the occurrence of a specified event. The alarm assembly includes a locking mechanism coupled to a substrate which has a natural frequency. The locking mechanism is maintained in a condition which inhibits the natural frequency of the substrate unless commanded to do so by an electronic circuit which includes sensors for monitoring one or more specific criterion. The locking mechanism is preferably a non-Newtonian flow fluid locking mechanism which uses a magneto-rheological fluid to dynamically adjust the locking strength of the locking mechanism as well as the natural frequency of the substrate based upon user inputs and dynamic events. The alarm assembly can be dynamically “tuned” in and out of the natural frequency of the substrate so the substrate vibrates, produces an audible noise, or generates a current upon the occurrence of a predetermined event.

  • Publication number: 20010005172
    Abstract: A light-source lamp unit includes a light-source lamp unit detachably mounted, and a CPU constituting a drive and controller for the light-source lamp unit. The CPU senses lamp information obtained by a lamp-information storing block in the light-source lamp unit, pertaining to a lamp power rating, lamp life and whether a lamp is new or not, and starts counting operation time when the lamp is lit. The CPU compares the lamp life sensed and the operation time count, and forces the lamp to extinguish when the life of the light-source lamp expires. Prior to this action, the CPU gives a warning display before the life expiration of the lamp by a fixed duration of time, to warn that lamp replacement is needed. Because the lamp-information storing block in the light-source lamp unit stores the information about the lamp type and characteristics of the lamp, the light-source device can properly drive the lamp to light it and determine the lamp life even when a light-source lamp unit of a different type is used.

A reference signal generator (40) for generating reference signals at the different voltage threshold levels receives control signals from a central processing unit. These control signals determine the sequence of the voltage threshold levels. The different levels of the reference signals provide different comparator output signals which are further processed and evaluated for obtaining the status information in response to the measured circuit output signals.

The container for the tester preferably has magnetic strips along its bottom surface to permit temporary attachment to either the tongue of the trailer or the rear of the towing vehicle. The essential features of the tester are limited to only two simple single-pole/double-throw switches, positioned in tandem, and three diodes arranged as a simple "OR" gate in combination with an audio signal device. This simple circuitry permits a single operator to check (a) the integrity of the wiring harness connected to the towing vehicle's lighting circuits, without leaving the driver's seat of the towing vehicle, and (b) the integrity of the trailer lighting with two simple switch adjustments.

  • Patent number: 5977879
    Abstract: A display device having driving circuits one for each of its light-emitting elements permits easy inspection of the driving circuits. The display device is formed as a fluorescent display tube that has an array of light-emitting units each consisting of a light-emitting element and its driving circuit. The display device further has a multiple-stage AND circuit consisting of 2-input AND circuits connected sequentially. One input of each stage is connected to the output of one of the driving circuits, another input of the first stage is connected to a power line, and the output of the last stage is connected to an inspection terminal, so that inspection is performed by checking whether a driving voltage appears at the inspection terminal. By activating all the driving circuits, whether they are functioning properly when they are in operation is checked globally; then, by deactivating one of the driving circuits, whether they are functioning properly when they are not in operation is checked individually.

  • Patent number: 5955945
    Abstract: A system for use in monitoring the operation of motorcycle brake and tail lights is disclosed which, upon determination that a brake or tail light is not operating properly to provide a warning light signal, automatically provides an alternate warning light signal which is highly visible to traffic following the motorcycle. Current sensors are used to determine whether electricity is flowing through the brake light and tail light circuits, or, alternately, whether there is an open circuit condition in one or both circuits which is indicative of a burned-out bulb. If the tail light burns out, control switching elements are used to supply current to the left rear turn signal light, the right rear turn signal light, and the brake light to illuminate them, thereby providing a warning signal at the rear of the motorcycle.

  • Patent number: 5935180
    Abstract: A system for testing the electrical components of vehicles during manufacturing includes a hand held tester to which a translator unit can be detachably engaged and with which the tester is in RF communication. The translator unit can be detached from the tester and plugged into a test receptacle under a vehicle's dashboard to communicate with the vehicle by translating computer formatted data from the tester to vehicle bus-formatted data, and vice-versa. Then, the vehicle's VIN is scanned into the tester or manually input into the tester, and the tester transmits the VIN via an RF link in the assembly plant to a computer in the plant. Based on the VIN, the computer determines the electric equipment that the vehicle has, and the computer transmits this information back to the tester. The tester then determines which tests to execute, and the tester causes the translator unit to undertake these tests.

  • Patent number: 5933084
    Abstract: An indicator light for a motor vehicle includes a light source and a reflector, which directs light from the light source in a forward direction on a first screen having lines of optical elements, which converge the light beam received from the reflector on a second screen in front of the first screen. The second screen includes, through at least part of its thickness, colored bands and translucent bands which are arranged alternately with each other over the height of the screen. In the first screen, the lines of optical elements are separated from each other by opaque colored bands, which are aligned with the colored bands of the second screen.

  • Patent number: 5818331
    Abstract: The invention is directed to an automotive light signal which comprise a housing with at least one electric bulb inside. According to the invention, a portion of light emission from the signal is diverted in such a way that the driver can see the same light that is directed outside the vehicle. Thus, a failure-proof end-to-end check of the operability of the signal is accomplished by the driver without resorting to help of another person. The invention is especially important for brake and backing signals, which currently require the driver to request outside help to perform end-to-end checking.
