Assignee:

Visteon Global Technologies, Inc. - Dearborn MI

International Classification:

G01F 500

US Classification:

732025

Abstract:

A mass fluid flow sensor for determining the amount of fluid inducted into an internal combustion engine, for example, is disclosed. The mass fluid flow sensor includes an external intake fluid temperature element which improves the accuracy of the mass fluid reading. An external cold wire element is further provided which improves response time. The mass fluid flow sensor has an improved aerodynamic design which provides a lower system pressure drop. Moreover, the sensor is smaller and lighter and has fewer parts, thus providing better manufacturability. A molded one-piece isolated jet nozzle having a hot element disposed therein is included in the fluid sampling portion. Consequently, an improved lower internal flow passage pressure drop is achieved. Additionally, an improved signal to noise ratio, as well as a larger dynamic range is an advantageous consequence of the present invention. The present invention further provides improved electromagnetic interference performance.

Assignee:

Visteon Global Technologies, Inc. - Dearborn MI

International Classification:

G01F 168

US Classification:

7320422, 7320412

Abstract:

A slosh suppressor prevents damage to electronic components and wire bonds of a circuit module contained in a circuit chamber formed by the housing of a sensor module. The circuit module is positioned within the circuit chamber and has a silicon gel layer positioned thereon for protecting the circuit module from the environment. A housing cover is structured to engage the sensor housing and close the circuit chamber. The housing cover has a projection extending into the circuit chamber and engaging the silicon gel layer to reduce vibration in the silicon gel layer and protect the circuit module.

International Classification:

G01F 1/68

US Classification:

732025, 7320422

Abstract:

A device for measuring fluid flowing in a duct is disclosed. The device includes a housing having a first flow passage, a nozzle, a second flow passage, a first electrical element, and a second electrical element. The first flow passage receives a first portion of the fluid flowing in the duct. The nozzle is connected to the housing and in fluid communication with the first flow passage. The second flow passage is defined by at least a first and second surface disposed in the housing, wherein the first surface has a first surface portion inclined relative to a second surface portion. The first electrical element is mounted in the first flow passage proximate to the nozzle. The second electrical element is mounted in the second flow passage. The first and second electrical elements are connected to at least one circuit for detecting a characteristic of the flowing fluid.

Abstract:

A container lid retaining system includes a housing with a bottom wall and a perimeter wall attached to and extending upwardly from the bottom wall. The perimeter wall has an upper edge defining an opening extending into the housing. A cover is removably positioned on the perimeter wall to selectively close the opening. A flexible tether has a first end and a second end. The tether extends through the perimeter wall adjacent to the upper edge to position the first end within the housing. The tether extends through the cover to position the second end under the cover when the cover is positioned on the housing. A panel is attached to the first end to prevent the first end from is pulled through the perimeter wall. A stop is removably coupled to the tether adjacent to the second end to prevent the second end from being pulled through the cover.

Abstract:

A mass air flow sensor housing for reducing backflow includes a U-shaped air flow path having an elliptical inlet and an outlet. A mass air flow sensor is positioned in the U-shaped air flow path. A converging ellipse inlet to the U-shaped air flow path reduces turbulent air flow. A deflecting wedge positioned upstream of the outlet creates a low pressure area adjacent the outlet for promoting air flow through the U-shaped bypass.
