2. Cathode bias - Wikipedia

   en.wikipedia.org/wiki/Cathode_bias

   In electronics, cathode bias (also known as self-bias, or automatic bias) is a technique used with vacuum tubes to make the direct current (dc) cathode voltage positive in relation to the negative side of the plate voltage supply by an amount equal to the magnitude of the desired grid bias voltage.

3. Cruise control - Wikipedia

   en.wikipedia.org/wiki/Cruise_control

   The AMC "cruise command" unit was actuated through a push-button on the dashboard once the car's desired speed was reached. The throttle position was automatically adjusted by a vacuum control that opened and closed the throttle based on input from the speedometer cable rather than through an adjustable control on the dashboard.

4. Circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker

   Circuit breakers with higher ratings can have adjustable trip settings, allowing fewer standardized products to be used, adjusted to the applicable precise ratings when installed. For example, a circuit breaker with a 400 ampere frame size might have its over-current detection threshold set only 300 amperes where that rating is appropriate.

5. Reed switch - Wikipedia

   en.wikipedia.org/wiki/Reed_switch

   After the final seal is made, the switch cools and the internal pressure is less than one atmosphere. Reed switches sealed with a pressurized nitrogen atmosphere have a higher breakdown voltage and are useful for switching 220–240 VAC mains power. Reed switches with a vacuum inside the glass envelope can switch thousands of volts.

9. Power-on reset - Wikipedia

   en.wikipedia.org/wiki/Power-on_reset

   On an IBM mainframe, a power-on reset (POR) is a sequence of actions that the processor performs either due to a POR request from the operator or as part of turning on power. The operator requests a POR for configuration changes that cannot be recognized by a simple System Reset .
