Abstract: Fragrance delivery devices are disclosed. The fragrance delivery devices are designed to couple with an existing air supply of a room, such as a patient care room, and utilize air flow from the existing air supply to disperse a fragrance-carrying fluid from the fragrance delivery device into a surrounding environment. Methods of making and using fragrance delivery devices are also disclosed.

Abstract: A device can include a bar; a dynamic clamp assembled to the bar and configured to move with respect to the bar during use to capture dimensions of each of a plurality of physical objects to be measured; an orientation sensor; and a distance sensor configured to sense movement of the dynamic clamp with respect to the bar.

Abstract: An oriented distance measuring system can include a rail; an odometer including a wheel; a first controller; and a first sensor in communication with the first controller, the first sensor configured to sense rotation of the wheel, the first controller configured to collect data from the first sensor, the data being associated with the rotation of the wheel; and a second sensor configured to sense roll, pitch, and yaw of the system.
