Abstract:
A method and apparatus for measuring static pressure. A tube is positioned within a hole in a structure. The hole has a hole diameter that is larger than a tube diameter of the tube such that a gap is formed between the tube and the hole. A first portion of deflected fluid that is deflected from a flow of fluid passing over the hole enters the gap and a second portion of the deflected fluid enters the tube. The static pressure of the fluid is measured at a location of the hole with the tube positioned within the hole.
Abstract:
Shear force and pressure on a structure are simultaneously monitored using signals received from antennas on the structure. The shear force on the structure is monitored using a signal received from a patch antenna on the structure, and the pressure on the structure is monitored using a signal received from a loop antenna on the structure.

Abstract:
A process of obtaining a fabric. The process includes obtaining an image of a paper product having a three-dimensional structure. A pattern is determined that corresponds to the three-dimensional structure of the paper product. The pattern is determined by using an image analysis program that is stored in a non-transitory computer-readable storage medium to analyze the image of the paper product. A fabric is obtained with a surface that approximates the pattern.
Abstract:
A wireless wearable device to passively detect fatigue in a user may include a suite of sensors including but not limited to accelerometry sensors for generating motion signals in response to a user's body motion, force sensors for generating force signals in response to force exerted by a body portion on the force sensor, and biometric sensors for generating biometric signals indicative of biometric activity including GSR, EMG, bioimpedance, image sensors, and arousal in the SNS. The suit of sensors may operate to passively determine, one or more of TRHR, systemic inflammation (I), contraction (C) (e.g., due to dehydration), stress, fatigue, and mood without any intervention or action on part of the user. The suite of sensors may comprise sensors distributed among a plurality of wireless wearable devices that are wirelessly linked and may share sensor data and data processing in making determinations of fatigue in the user.
Abstract:
An apparatus for measuring a volume of fluid includes at least one emitter configured to project a signal toward a predetermined position of a sample container, at least one receiver configured to receive the signal after the signal interacts with the sample container and a fluid transfer device in communication with the receiver and sample container. A change in the signal received by the receiver indicates when the fluid has dropped below the predetermined position. The apparatus determines a volume of fluid that the fluid transfer device has removed from the sample container when the receiver detects that the fluid has dropped below the predetermined position.
Abstract:
A magnetic field sensor comprises a substrate and a moving part which is displaced when subjected to a Laplace force. There is a gauge for measuring the displacement of the moving part. There is a suspended lever that is rotationally displaced about an axis of rotation at right angles to the direction of displacement of the moving part. The lever is connected to the moving part to transmit displacement of the moving part to the lever to cause rotation of the lever about the axis of rotation. The lever is also connected to a first part of the gauge. The sensor comprises a hinge that connects the lever to the substrate. The hinge allows the rotation of the lever about its axis of rotation and is rigid to allow for a lever arm effect. The second part of the gauge is fixed with no degree of freedom to the substrate.
Abstract:
Systems and methods for prediction and measurement of overlay errors are disclosed. Process-induced overlay errors may be predicted or measured utilizing film force based computational mechanics models. More specifically, information with respect to the distribution of film force is provided to a finite element (FE) model to provide more accurate point-by-point predictions in cases where complex stress patterns are present. Enhanced prediction and measurement of wafer geometry induced overlay errors are also disclosed.
