  • Patent number: 10368405
    Abstract: A dimming circuit for an indicator switch has a control input, a dimming state and a non-dimming state. The dimming circuit is responsive to the presence of a backlight PWM signal at the control input of the dimming circuit to switch to the dimming state and responsive to the absence of the backlight PWM signal at the control input of the dimming circuit to switch to the non-dimming state. In the dimming state a high resistance of the dimming circuit is coupled in series with the indicator LED and a LED drive output of the function control module and in the non-dimming state a low resistance of the dimming circuit is coupled in series with the indicator LED and the LED drive output of the function control module. The high resistance has a resistance higher than the low resistance.

  • Patent number: 6371768
    Abstract: An electrical connector assembly has a male and female connector. The male connector has electrical contacts in a housing for conducting AC or DC current. The female connector also includes a housing with electrical contacts to electrically couple with the male electrical contacts. The electrical contacts are coupled between a power source and a rechargeable power user, such as batteries in an electric vehicle. A mechanism to terminate power of the rechargeable power user is coupled with the system to prohibit use of the rechargeable power user during charging.

  • Patent number: 6225153
    Abstract: An electrical connector assembly has a male connector and a female connector. The male connector has electrical contacts for conducting AC or DC current. The female connector includes electrical contacts for coupling with the male electrical contacts for conducting the AC or DC current. A mechanism to eliminate current arcing during disconnection of the male and female connectors is coupled with at least one of the male or female connectors.

  • Patent number: 6203355
    Abstract: An electrical connector assembly has a male and female connector. The male connector has a housing with electrical contacts to conduct AC or DC current. The female connector also includes a housing to couple with the male housing. The female housing includes electrical contacts to electrically couple with the male electrical contacts. A latch mechanism is associated with the male or female connector housing to releasably couple the male and female connectors together. A lock mechanism is coupled with the latch mechanism to prohibit unauthorized disconnection of the male and female connectors in a coupled position.

  • Patent number: 6062899
    Abstract: A digital verification system and method is described for verifying that the terminal connector assembly of an automobile's battery cable is properly connected to the connector assembly of a power distribution module (PDM). The terminal connector assembly is provided with an integrated CPA assembly having an engagement member, such as an elongated appendage. The PDM connector assembly is provided with a shorting bar that contacts a bus bar so as to cause a short circuit to occur when current is supplied to the PDM connector assembly through the battery's terminal connector assembly. A sense lead in contact with the shorting bar sends a response signal through a printed circuit board to a microprocessor indicating that electrical power is flowing though the short circuit. The CPA assembly can only be engaged when the terminal connector assembly is fully mated to the PDM connector assembly.
