Strain gage based system and method for failure detection of a fluid film bearing
A system and method for detecting a failure of a fluid film bearing is disclosed. The system and method use one or more non-laser based strain transducers to detect changes in the frequency spectrum of the pressure of the fluid film at one or more locations in the bearing to identify failure or the risk of failure of the bearing. The system and can use metallic film, piezoelectric, and piezoresistive strain sensors to generate alarms when particular frequency bands become present in the strain frequency spectrum. The system and method can also generate strain orbit plots and perform waveform analysis of the time varying strains in the bearing housing caused by time-varying changes in the pressure of the fluid film.
Determining Stresses in a Pipe Under Non-Uniform Exterior Loads
Systems and methods for determining stresses in pipe under non-uniform exterior loads to test the pipe design for structural integrity by approximating non-uniform exterior loads on the pipe and performing a stress analysis of the pipe under the non-uniform exterior loading to determine the stresses in the pipe.

Detection device of load and moment, and artificial limb including the detection device
The present invention provides a detection device for detecting a load and moment and capable of increasing the output by a strain gage. The detection device is provided with a characteristic sensor block. The sensor block includes a base having an axis extending in the direction of a load to be detected, a front side wall raised from the base at a position offset from the axis of the base, a rear side wall raised from the base at a position offset from the axis of the base in the direction opposite the front side wall, and an upper wall for connecting the upper end of the front side wall and the upper end of the rear side wall. The sensor block supports each strain gauge on the upper surface of the upper wall. The upper wall includes a center portion located at the center between the front side wall and the rear side wall, a first portion located between the center portion and the front side wall, and a second portion located between the center portion and the rear side wall. The first portion and the second portion, which support the strain gauges, have a smaller thickness than the center portion and are relatively easily deformed or strained.
MULTI-ANGLE PRESSURE SENSING DEVICE
A device able to sense pressure from multiple directions includes a substrate and an elastic member comprising a bottom end and a touch end. The bottom end is arranged on the substrate, and the touch end is configured to receive an external force. A group of pressure detecting units are arranged on the touch end, each pressure detecting unit is a curved shape and comprises a first end and a second end, the first end being fixed on the substrate, and the second end is fixed with the elastic member. Distances between each first end and the bottom end are same, and a first signal processing unit is electrically connected with the at least two detecting units.
CHUCK TABLE FOR A WAFER CLEANING TOOL
A chuck table for supporting a wafer assembly during a cleaning process comprising an axis of rotation, a first surface including an opening configured to be in communication with a vacuum source, and a second surface opposing the first surface. The second surface includes a suction opening displaced radially from both the opening in the first surface and the axis, the suction opening being in communication with the opening in the first surface such that in use a suction force can be applied via the suction opening.
VISUO-HAPTIC SENSOR
The present disclosure presents a visuo-haptic sensor, which is based on a passive, deformable element whose deformation is observed by a camera. In particular, the improved simplified sensor may determine the force and/or torque applied to a point of the sensor in multiple spatial dimensions.
Load Sensor System with Improved Assembly Connection
A load sensor disposed between an air suspension assembly of a vehicle and a vehicle suspension, wherein the load sensor generates a load signal which varies based on an amount of force transferred from said vehicle frame to said vehicle suspension, wherein the load signal can be received by a load calculator to allow calculation of the load exerted from said vehicle frame to the vehicle suspension.
