Accordingly, the present inventors have devised, among other things, an exemplary dial-type flow-restriction gauge that is inexpensive to manufacture and performs reliability and consistently over a wide temperature range. One exemplary gauge includes an external dial that rotates relative a restriction scale in response to a differential pressure. Placement of the dial on the exterior of the gauge eliminates the need to use clear material and allows embedding of the restriction scale into an exterior surface of the gauge.Type: GrantFiled: April 17, 2009Date of Patent: April 12, 2011Assignee: Engineered Products CompanyInventors: H.

Patent number: 7921721Abstract: An oil-filled pressure transducer including a glass pre-form having contact pins and a oil-filled tube, each running top to bottom through holes in the pre-form. The oil-filled tube extends beyond the top of the pre-form. A glass alignment plate has an alignment aperture designed to fit over the extended oil-filled tube and-another aperture placed at a predetermined position from the alignment aperture which is shaped to accommodate a sensor. When the plate is aligned over the oil-filled tube, a sensor module can be positioned accurately in the alignment aperture so that contact is made with the pins. A header having a central diaphragm is placed over the pre-form and the aligned sensor creating a space between the diaphragm and the sensor which is filled with oil. The transducer utilizes less oil and exhibits a lower backpressure with increasing temperature than other oil-filled pressure transducers of similar size.Type: GrantFiled: April 9, 2009Date of Patent: April 12, 2011Assignee: Kulite Semiconductor Products, Inc.Inventor: Anthony D.

Patent number: 7921723Abstract: A membrane unit configured for use in a housing of a pressure measuring unit, preferably for measuring pressure in an extra-corporal blood circuit, has a flexible membrane and a fixing ring which is integral with the membrane so that the membrane and the fixing ring form a one-piece element. The fixing ring has a lower flexibility than the membrane, and has fixing elements for fixing the fixing ring to the pressure measuring housing.Type: GrantFiled: September 10, 2009Date of Patent: April 12, 2011Assignee: Fresenius Medical Care Deutschland GmbHInventors: Reinhold Reiter, Marco Caronna

Patent number: 7921724Abstract: A single pressure sensing capsule has a reference pressure ported to the rear side of a silicon sensing die. The front side of the silicon sensing die receives a main pressure at another port. The silicon sensing die contains a full Wheatstone bridge on one of the surfaces and within the active area designated as the diaphragm area. Thus, the difference of the main and reference pressure results in the sensor providing an output equivalent to the differential pressure, namely the main pressure minus the reference pressure which is the stress induced in a sensing diaphragm. In any event, the reference pressure or main pressure may be derived from a pump pressure which is being monitored. The pump pressure output is subjected to a pump ripple or a sinusoidally varying pressure. In order to compensate for pump ripple, one employs a coiled tube. The tube length is selected to suppress the pump ripple as applied to the sensor die.Type: GrantFiled: October 6, 2009Date of Patent: April 12, 2011Assignee: Kulite Semiconductor Products, Inc.Inventors: Anthony D.

Patent number: 7921726Abstract: A fluid detection device is herein disclosed as including a sensor mount, a flexible deflection sensor rigidly connected to the sensor mount and a stiffener. The stiffener is arranged together with the flexible deflection sensor such that the flexible deflection sensor is preconfigured to deform in a predetermined manner when the fluid detection device is exposed to a fluid. An amount of the deformation of the flexible deflection sensor determines a property of the fluid. A pressure sensing apparatus is herein disclosed as including a rigid perimeter, a flexible membrane forming a surface area bounded by the perimeter, and a sensing means in communication with the flexible membrane. The flexible membrane is configured to elastically deform when a pressure force is exerted on the surface area, and the sensing means is configured to measure an amount of deformation of the flexible membrane.Type: GrantFiled: June 7, 2007Date of Patent: April 12, 2011Assignee: Precision Pumping Systems, Inc.Inventor: Paul L.

Patent number: 7921727Abstract: A sensing system for use in monitoring the structural health of a structure such as a polymeric matrix composite structure is provided. The system includes a sensor formed from a conductive ink containing carbon nanofibers and a polymeric resin, and a data acquisition system for acquiring and evaluating data from the sensor. The conductive ink may be applied directly to the structure to be monitored in the form of a grid pattern. Damage to the structure may be detected by measuring changes in resistance values detected from the sensor.Type: GrantFiled: June 24, 2005Date of Patent: April 12, 2011Assignee: University of DaytonInventor: Brian P.

Patent number: 7921728Abstract: A flexible apparatus and method to enhance capacitive force sensing is disclosed. In one embodiment, a force measuring device includes a sensor capacitor having a fixed surface and a moveable surface substantially parallel to the fixed surface, at least one spring assembly (e.g., may deflect longitudinally and/or perpendicularly to a direction of the force) positioned between the fixed surface and the movable surface (e.g., the spring assembly may alter in height in response to a force applied perpendicular to the movable surface and to cause a change in the gap between the fixed surface and the movable surface), and a circuit to generate a measurement of the force based on an algorithm that considers a change in a capacitance of the sensor capacitor. A reference capacitor may adjust the measurement of the applied force based on one or more environmental conditions.Type: GrantFiled: February 18, 2008Date of Patent: April 12, 2011Assignee: YPoint Capital, IncInventors: William D.
