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.

Abstract: A hypodermic interface assembly is disclosed. The hypodermic interface assembly includes a hub; a cannula; a core member; and a cannula carrier. The core member is non-removably connected to the cannula. The cannula carrier is non-removably connected to the attachment member. The cannula carrier is controllably separable from the hub. A subassembly is also disclosed. The subassembly includes a hub; a cannula; and a core member. A proximal end surface of the core member is arranged at a predetermined hub-core distance away from a distal end surface of the hub.

Abstract: A self-contained viscous liquid dispenser having an improved vent valve is provided. The vent valve includes a plug member having a sealing ridge at its perimeter. The vent valve is activated at reduced pressure differentials between the inside and outside of the dispenser. The vent valve also provides redundant sealing capability.

Abstract: A dispenser for dispensing metered amounts of a viscous liquid includes a liquid reservoir and a pump chamber having an opening in communication with the reservoir. A pump mechanism including a pump cylinder with a dispensing channel therethrough is configured with the pump chamber and is movable from a rest to a pressurizing position upon actuation thereof to pressurize liquid within the pump chamber. A dispensing orifice is defined at one end of the dispensing cylinder. A check valve mechanism is disposed in the opening. During shipment or storage, the pump cylinder is locked in pressurized position. When locked in pressurized position, the dispensing channel engages the check valve to seal the opening and also prevent flow from the pump chamber to the dispensing channel.

Abstract: A system for coupling, uncoupling and controlling the operating parameters of the header assembly on an agricultural combine. A fixed coupler block on the feeder assembly of the combine is coupled with a movable coupler block on the header assembly to join hydraulic and electrical conduits by rotating a coupler handle to lock the blocks together. As the handle rotates, it also causes push-pull cables to actuate latch pins which mechanically couple the header assembly to the feeder assembly. The system senses whether a header assembly is present or not and, if present, what type of header assembly is present. In the latter case, the system then controls the operating parameters of the header assembly.
