Patent number: 8175835Abstract: A sensor includes one or more sensor transducers coupled with a signal conditioning IC incorporating signal conditioning circuitry and memory devoted to storing end-user downloadable coefficients. In a preferred embodiment, the IC is an ASIC and the end-user downloadable coefficients are pre-selected by the end-user based on its needs, and the coefficients are pre-stored in the ASIC when the sensor is calibrated. This results in a more cost-effective and space-efficient sensor device with improved functionality over that available in the prior art.Type: GrantFiled: May 17, 2006Date of Patent: May 8, 2012Assignee: Honeywell International Inc.Inventors: Anthony M.

Publication number: 20080236273Abstract: A mass airflow sensor is disclosed that includes a heating element comprising an upstream side and a downstream side. Two resistive temperature sensors are placed on each side of the heating element and assuming mass air/liquid flows in a direction from left to right. The resistors are configured electrically in a Wheatstone bridge configuration. A regulated voltage is applied across the mass flow sensing, Wheatstone bridge. The regulated voltage is set high enough to produce self-heating effects on the sensing bridge. The central heating element will also be heated. As mass air/liquid flows across the temperature sensors and the heating element, the upstream (RU1 and RU2) resistors are cooled and the downstream (RD1 and RD2) resistors are heated. The resistance in the resistive temperature sensors changes with temperature creating a differential voltage signal proportional to the regulated voltage applied to the sensing Wheatstone bridge and rate of mass air/liquid flow.Type: ApplicationFiled: March 27, 2007Publication date: October 2, 2008Inventors: Anthony M. Dmytriw, Craig S. Becke

Patent number: 7280927Abstract: A method and system for providing a linear signal from a flow transducer. A non-linear raw signal can be obtained from a mass flow transducer. An approximated error comprising a discrete sinusoidal function incremented by a variable and selectable omega value can then be subtracted from the non-linear raw signal, in order to provide a subtracted result and reduce an error range thereof. The linear signal can then be obtained from the subtracted result in order to linearize a raw output from the flow transducer. A user is thus permitted to tune a frequency increment associated with the variable and selectable omega value in order to reduce the error range thereof. Linearized airflow and liquid flow sensor outputs can thus be generated by allowing a user the freedom to tune the frequency increment depending upon the user's flow range for reducing errors.Type: GrantFiled: October 11, 2006Date of Patent: October 9, 2007Assignee: Honeywell International Inc.Inventor: Anthony M.

Patent number: 7277802Abstract: A method and system for providing a linear signal from mass flow transducer approximates the error from the original raw signal using discrete sine functions and subtracts the approximated error from the original raw signal. The method and system can be implemented using an ASIC (Application Specific Integrated Circuit) mated with a raw mass flow transducer. The method and system for linearizing the signal can be contained in the ASIC, and allows for improved accuracy in the linear signal with few coefficients and mathematical steps.Type: GrantFiled: May 18, 2006Date of Patent: October 2, 2007Assignee: Honeywell International Inc.Inventor: Anthony M.
