  2. Mean arterial pressure - Wikipedia

    en.wikipedia.org/wiki/Mean_arterial_pressure

    In medicine, the mean arterial pressure (MAP) is an average calculated blood pressure in an individual during a single cardiac cycle. [1] Although methods of estimating MAP vary, a common calculation is to take one-third of the pulse pressure (the difference between the systolic and diastolic pressures), and add that amount to the diastolic pressure.

    The MAP sensor is then used for rationality checks and to test the EGR valve. The way they do this is during a deceleration of the vehicle when there is low absolute pressure in the intake manifold (i.e., a high vacuum present in the intake manifold relative to the outside air) the powertrain control module (PCM) will open the EGR valve and ...

    en.wikipedia.org/wiki/Cardinal_direction

    Direction determination refers to the ways in which a cardinal direction or compass point can be determined in navigation and wayfinding.The most direct method is using a compass (magnetic compass or gyrocompass), but indirect methods exist, based on the Sun path (unaided or by using a watch or sundial), the stars, and satellite navigation.

    Traffic indication map (TIM) is a structure used in 802.11 wireless network management frames. The traffic indication map information element is covered under section 7.3.2.6 of 802.11-1999 standard. [1] The IEEE 802.11 standards use a bitmap to indicate to any sleeping listening stations that the access point (AP) has buffered data waiting for it.

    Upon receipt of an indication that the destination party is now ready to receive short messages, the HLR sends an AlertSC MAP message to each of the SMSCs registered in the MWD list for the subscriber, causing the SMSC to start the Short Message delivery process again, from the beginning.

  8. Moving map display - Wikipedia

    en.wikipedia.org/wiki/Moving_map_display

    A moving map display (MMD) / projected map display (PMD) is a type of navigation system output that, instead of numerically displaying the current geographical coordinates determined by the navigation unit or an heading and distance indication of a certain waypoint, displays the unit's current location at the center of a map. As the unit moves ...
