  • Patent number: 12005901
    Abstract: A method of controlling a brake lamp of a vehicle including an electric motor as a power source includes determining whether gear shifting is required and whether there is a forward section with a suddenly changing slope when regenerative braking is performed through the electric motor without manipulation of an accelerator pedal or a brake pedal, delaying the gear shifting until the gear shifting exceeds a gear-shifting limit when the gear shifting is required and when there is the forward section with the suddenly changing slope, calculating acceleration based on regenerative braking torque while the gear shifting is delayed, and controlling the brake lamp based on the calculated acceleration.

  • Patent number: 5885355
    Abstract: A semiconductor fabrication apparatus having a process chamber and a handler which is provided for loading wafers into the process chamber or unloading wafers therefrom, comprising a plurality of switches for detecting positions of the handler and for generating detection signals in accordance with the positions; and an indicator for indicating normal operations of the switches. The indicator has relays operated in accordance with a voltage level of each of the detection signals; and LEDs associated with each of the relays, for identifying a normal operation of the handler. By confirming the conductive/nonconductive state of the LED, the operator can easily determine if the switches are accurately detecting the position of a load fork and/or an aligning plate.
