Abstract:

Sensor systems and methods are disclosed herein, including a sensor chip, upon which at least two surface acoustic wave (SAW) sensing elements are centrally located on a first side (e. g. , front side) of the sensor chip. The SAW sensing elements occupy a common area on the first side of the sensor chip. An etched diaphragm is located centrally on the second side (i. e. , back side) of the sensor chip opposite the first side in association with the two SAW sensing elements in order to concentrate the mechanical strain of the sensor system or sensor device in the etched diagram, thereby providing high strength, high sensitivity and ease of manufacturing thereof.

International Classification:

G01M 15/00

US Classification:

731173

Abstract:

A torque sensor system and method. An automotive engine is located opposite a torque converter, such that a shaft extends from the engine and interacts with the torque converter. A target is located between the engine and torque converter. One or more torque sensors can be integrated with one or more position sensors for detecting a position associated with the shaft, wherein the torque sensor(s) and the position sensor(s) are integrated into a single torque sensor package to thereby provide enhanced sensing of the target in association with a rotation of shaft during an actuation of the engine.

Steven J. Magee - Lena IL, US

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

G01D 9/00

US Classification:

73650, 738665

Abstract:

A device for mounting a sensor on a device being subjected to torque such as a shaft or plate in the form of a retaining ring having an opening or chamber sized to hold the sensor. The ring has a first open end for insertion of the sensor into the chamber or opening and a second end having a lip for retaining the sensor in the opening. The second end has an opening for the sensor wires or other connecting elements. The ring has threads on the outer periphery of the retaining ring for engaging similar threads on the device being subjected to torque.

Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

G01N 29/04
G01L 3/02

US Classification:

73801, 73862191

Abstract:

A torque sensor is disclosed based on a SAW die configured on a surface of a plate, and an isolator formed from a flexible material. The isolator is rigidly mounted to the plate, such that the isolator flexes when a force perpendicular to the surface of the plate are applied while transferring a torque that is applied within a plane of the plate to the SAW die, thereby eliminating or minimizing the effect on the SAW die of out-of-plane forces on the plate so as to isolate the torque transferred to the plate.

Abstract:

A magneto-elastic torque sensor and system include a substrate and a magneto-elastic sensing component formed from or on the substrate. The magneto-elastic sensing component and the substrate together form a magneto-elastic torque sensor, which when subject to a stress associated with a torque, shifts a characteristic frequency thereof linearly in response to the torque, thereby inducing a pathway by which magneto-elastic energy is coupled to excite vibrations in a basal plane of the magneto-elastic sensor, thereby generating torque-based information based on a resonant frequency thereof.

International Classification:

G01N 25/62

US Classification:

073335060, 073335040

Abstract:

Sensor systems and methods are disclosed herein. A relative humidity sensor is generally associated one or more porous heating elements. A porous resistive material surrounds the relative humidity sensor. Additionally, one or more flat heating elements can be bonded to a base of the relative humidity sensor to conduct heat and insure uniform heating about the relative humidity sensor. The porous heating elements can be configured to permit humid air to pass through the porous heating elements. Also, the porous heating element(s) can be assembled slightly offset from a surface of the relative humidity sensor so that air that is saturated with water vapor passes through and is heated by the porous heating element in order to evaporate water droplets associated with the water vapor and thereby reduce relative humidity to a measurable level. The porous resistive material can be configured from a material such as, for example, tantalum or nichrome. The porous resistive material can also be configured in a sheet arranged in a woven pattern.
