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.

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.

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.
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.
Contaminant Free Backflow Reducing Insert For Mass Air Flow Sensors

Abstract:
A housing structure for mass air flow sensors includes an auxiliary passage way, internal to the structure, that diverts a portion of the main air flow towards sensing elements. The sensing elements are shielded from the main air flow, so the contaminants separate from the diverted air at the point of diversion and continue downstream in the main air flow. The decontaminated, diverted air passes over the sensing elements and out of the housing structure through two exit openings located in the rear of the structure. The housing structure, by locating the sensing elements within itself, away from the main air flow, and locating exit openings for the diverted air behind a blocking wall, is also able to eliminate the effect of backflow air over the mass air flow sensing elements.
