  2. Smart key - Wikipedia

    en.wikipedia.org/wiki/Smart_key

    The smart key allows the driver to keep the key fob pocketed when unlocking, locking and starting the vehicle. The key is identified via one of several antennas in the car's bodywork and an ISM band radio pulse generator in the key housing. Depending on the system, the vehicle is automatically unlocked when a button or sensor on the door handle ...

  4. Car key - Wikipedia

    en.wikipedia.org/wiki/Car_key

    Car key in ignition Car ignition and steering wheel lock. A car key or an automobile key is a key used to open and/or start an automobile. Modern key designs are usually symmetrical, and some use grooves on both sides, rather than a cut edge, to actuate the lock. It has multiple uses for the automobile with which it was sold.

  5. Tilt detector - Wikipedia

    en.wikipedia.org/wiki/Tilt_detector

    Depending on the application, the accuracy of the tilt sensor must be adapted to the sensitivity of the object it is intended to monitor. Indeed, they can indicate precisely the level of inclination with a digital dial ( as for the inclination sensors on some vehicles) or simply have an indicator that changes color when an inclination beyond ...

    A group of tell-tales showing lights for "brake fluid", "stop lamp" and "check engine" Graphical tell-talesA tell-tale, sometimes called an idiot light [1] or warning light, is an indicator of malfunction or operation of a system, indicated by a binary (on/off) illuminated light, symbol or text legend.

  7. Indicator (distance amplifying instrument) - Wikipedia

    en.wikipedia.org/wiki/Indicator_(distance...

    Ideal test indicator pushed. Prior to modern geared dial mechanisms, test indicators using a single lever or systems of levers were common. The range and precision of these devices were generally inferior to modern dial type units, with a range of 10/1000 inch to 30/1000 inch, and precision of 1/1000 inch being typical.

  8. Capacitive sensing - Wikipedia

    en.wikipedia.org/wiki/Capacitive_sensing

    ITO allows the capacitive sensor to be up to 90% transparent (for one layer solutions, such as touch phone screens). Size and spacing of the capacitive sensor are both very important to the sensor's performance. In addition to the size of the sensor, and its spacing relative to the ground plane, the

  9. Coordinate-measuring machine - Wikipedia

    en.wikipedia.org/wiki/Coordinate-measuring_machine

    A coordinate-measuring machine (CMM) is a device that measures the geometry of physical objects by sensing discrete points on the surface of the object with a probe. Various types of probes are used in CMMs, the most common being mechanical and laser sensors, though optical and white light sensors do exist.
