Abstract: A mounting system for an encoder is disclosed. The mounting system prevents rotation about the encoder shaft's axis of rotation. The mounting system allows translation in a plane perpendicular to the encoder shaft's axis of rotation.

Abstract: In an example, a method for automated camera flat fielding and alignment may include determining a magnification of a camera relative to a first camera axis that is generally parallel to a first print media axis by evaluating first and second magnifications between transitions from a first color to a second color on a setup plot. The method may further include determining, by a processor, a rotation of the camera relative to the first camera axis such that the first magnification is approximately equal to the second magnification.

Abstract: A fluid-ejection device includes a handheld and/or mountable enclosure, a pneumatic fitting, an electrical connector, and a controller. The pneumatic fitting extends from and/or through the enclosure and is receptive to placement of a tip thereon. The tip contains a supply of fluid, a fluid-ejection mechanism, and an electrical connector for the fluid-ejection mechanism. The electrical connector extends from and/or through the enclosure and is receptive to electrical coupling of the electrical connector of the tip. The controller is situated within the enclosure to cause the tip to eject the fluid via the electrical coupling of the electrical connectors of the tip and the fluid-ejection device.

Abstract: A flow measurement cartridge assembly for measuring liquid flow in a partially filled channel and a method for measuring liquid flow using the cartridge assembly, the cartridge assembly comprising: a frame for insertion into a discharge opening of the channel; a level detector secured in the frame for determining a liquid level in the channel; and at least one flow measurement device secured in the frame.

Abstract: Embodiments of the present invention comprise one-part elastomeric valves which are manipulated after molding to preload the valve seal. The valves maintain positive seal until a fluidic pressure or mechanical force is applied to open the valve. The valves return to a closed state after the pressure or force is removed.

Abstract: Apparatuses, methods, systems, and arrangements enable a modular and/or adaptable ink supply system for printing devices. In certain implementations base ink containers having ink couplings are designed for use individually or grouped together with a carrier. Ink cartridges of various sizes and purposes may therefore be manufactured and operationally employed utilizing one or more substantially identical base ink containers. In certain (alternative but non-exhaustive) implementations, a carrier may include a lid that serves to aid retention of the base ink containers against the carrier and/or to facilitate the use of the ink couplings of the base ink containers. Additionally, an ink cartridge, with one or multiple base ink containers, may optionally employ a single memory chip apparatus for utilization of intelligent printing functions. Those ink cartridges with multiple base ink containers may hold a single hue of ink or multiple different hues of ink.

Abstract: A security apparatus for restricting the opening of a door in a frame consisting of lag bolts screwed into the frame near opposite edges of the door and a nylon belt fastened to each lag bolt. An aperture is formed near each end of the belt and the lag bolts are extended through the apertures in order to fasten the belt to the bolts. The belt can be elongated slightly, and it is preferred that the distance between the apertures is slightly less than the distance between the bolts. Any elongation above a specified amount requires substantially higher force than that required to elongate the belt for putting it in its operable position.
