An apparatus for intended use in measuring, sensing, or detecting a characteristic of a fluid, such as a liquid food product, is disclosed. The apparatus includes a body having a pocket for positioning adjacent to the opening in a pipe or like structure for receiving a portion of a fluid therein. In one possible use, a first optical medium, such as an optical fiber, transmits light from a source toward a portion of the fluid flow entering the pocket. Light received by one or more optical mediums positioned in backscatter, sidescatter, or transmission configurations relative to the first optical medium is detected by a corresponding sensor or detector. Using the output of this sensor or detector, an optical characteristic of the fluid may be measured. An overall system using the apparatus and related method for detecting an optical characteristic of a fluid are also disclosed.

A bottom portion of an intake port is provided with a sloped bottom surface formed of a plane such that sloped bottom surface approaches the side surfaces of external teeth and internal teeth from an upstream side to a downstream side in rotational direction of two rotors. Fluid that flows in the intake port is regulated by the sloped bottom surface and smoothly guided into individual inter-teeth chambers that are expanding. Since the sloped bottom surface on the bottom portion of the intake port is formed of a plane without spiral or twisting, design and manufacturing of a gear pump is extremely easy.

A solenoid-actuated diaphragm valve achieves minimal dead volume, tolerance of high pressures, prolonged diaphragm life, and energy conservation using a three-sector diaphragm in concert with a constraining plate which confines vertical displacement to the central sectors of the diaphragm.

Apparatus, system and method for providing pressurized infusion of liquids and, more particularly, providing a stable and pressurized flow of fluid to the eye during surgery. Aspiration fluid may be received via an aspiration line at a first peristaltic pump, where aspiration fluid is transferred to a Venturi tank reservoir coupled to a second peristaltic pump. Fluid from a fluid source is provided via a third peristaltic pump to a pressurized infusion tank. A determination is made if the pressure in the pressurized infusion tank is at a predetermined level, where fluid may be transferred from the pressurized infusion tank to an irrigation line when pressure in the pressurized infusion tank is determined to be at the predetermined level. Alternate activation of a plurality of aspiration and irrigation lines are also provided.
