Inertial measurement unit. An inertial measurement unit (IMU) is an electronic device that measures and reports a body's specific force, angular rate, and sometimes the orientation of the body, using a combination of accelerometers, gyroscopes, and sometimes magnetometers. When the magnetometer is included, IMUs are referred to as IMMUs.
An inertial navigation system (INS; also inertial guidance system, inertial instrument) is a navigation device that uses motion sensors (accelerometers), rotation sensors (gyroscopes) and a computer to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object ...
Kālua puaʻa (kālua pig) Kālua is a traditional Hawaiian cooking method that utilizes an imu, a type of underground oven. The word " kālua " ("to cook in an underground oven" in the Hawaiian language) may also be used to describe the food cooked in this manner, such as kālua pig or kālua turkey, which are commonly served at lūʻau feasts.
The Hawaiian imu was the easiest way to cook large quantities of food quickly and efficiently for the Hawaiians. Because their creation was so labor-intensive, imus were only created for special events or ceremonies where it would be worth the time and hard work. An imu is created by first digging a 2- to 4-foot hole in the ground. Porous rocks ...
Indiana Memorial Union. The Indiana Memorial Union (IMU) is a student union building at Indiana University in Bloomington, Indiana United States. It is located at 900 E 7th Street, facing the Campus River and the Dunn Meadow. The Indiana Memorial Union was dedicated on June 13, 1932. At nearly 500,000 square feet (46,000 m 2), it is one of the ...
The main difference between an Inertial measurement unit (IMU) and an AHRS is the addition of an on-board processing system in an AHRS, which provides attitude and heading information. This is in contrast to an IMU, which delivers sensor data to an additional device that computes attitude and heading.
Inertial reference unit. An inertial reference unit (IRU) is a type of inertial sensor which uses gyroscopes (electromechanical, ring laser gyro or MEMS) and accelerometers (electromechanical or MEMS) to determine a moving aircraft ’s or spacecraft ’s change in rotational attitude (angular orientation relative to some reference frame) and ...
mathunion.org. The International Mathematical Union (IMU) is an international organization devoted to international cooperation in the field of mathematics across the world. It is a member of the International Science Council (ISC) and supports the International Congress of Mathematicians (ICM). Its members are national mathematics ...
