摘要： A system and method are provided for inspecting challenging material locations such as holes. The system may include a sensor cartridge (“mandrel”) for hole inspection that has a helical portion to which a sensor array is attached. The radius of the helical portion can be increased or decreased by applying a torque to the helical portion thereby allowing the sensor to be inserted into a hole or pressed against the wall of the hole. A scanner is described to which mandrels can be quickly connected and changed enabling an inspector to quickly switch between different mandrels (e.g., for different holes sizes and sensor configurations). Also disclosed is an inspection procedure and data processing algorithm for performing an inspection. The data processing algorithm utilizes a signature library for enhancing the detection or sizing of features of interest such as cracks. The algorithm and library can account for material edges, various material types.

摘要： Eddy current sensing is governed by the diffusion equation of magnetoquasistatic fields. As such the eddy current sensor's proximity to the object to be inspected (i.e., “liftoff”) significantly affects the sensor's response signal. Methods and apparatus are disclosed for improving performance for an eddy current sensor, though they may also be used for other sensor types. These solutions are beneficial for both single channel eddy current sensors and arrays, and are particularly beneficial for measuring parts with complex surfaces. In some aspects improved performance is achieved by varying the stiffness of the mechanical support for the sensor. Some mechanical supports may exhibit anisotropic stiffness. After performing a scan with an eddy current array, a multi-channel shape filtering module is applied to improve defect detection. The module reduces the variability of defect response measured due to the unpredictability of the defect location transverse to the scan direction.

摘要： There is provided a device for measuring a user's oxygen-consumption. The device includes a tubular member with a first tapered portion through which an exhalation of air enters into the device, a second tapered portion, and a constriction between the portions thereof. The devices includes a flow sensing mechanism in communication with the first tapered portion of the tubular member. The device includes an oxygen sensor in communication with the first tapered portion of the tubular member. The device is configured such that the oxygen sensor is passively supplied a portion of the exhalation of air by means of positive or negative differential pressure referenced between the first tapered portion and at least one of ambient air and the constriction of the tubular member.

摘要： Monitoring of one or more key indicators can provide powerful insights into operation and state of different physical systems. For example, continuous monitoring of multiple analyte in body will allow for detailed insights into personal health and will allow for preventative health management. In this application, we present an ultra-small scale wireless sensing platform capable of long-term wireless in-vivo sensing. The key for extreme miniaturization lies in ultra-low-power compact design and lithographic integration of key system components. The key to low cost is using standard technologies and scalable manufacturing. For example, using standard semiconductor technologies for sensing, processing and wireless operation paves way to a low-cost integrated wireless sensing technology. Modern semiconductor technologies provide the capability to provide low-power and yet powerful electronics functionality in a small (mm-scale) size and wireless operation at high frequency. Furthermore, these technologies also present the possibility of integrating different components through wafer-scale lithographic integration. This application presents optimal design and processing methods for a small wireless multi-analyte sensing platform that can be used to monitor multiple analyte such as glucose, lactate, Urea and other physicochemical quantities and operates wirelessly. The design techniques and processing methods presented in this application can be used for a multitude of other applications and are not limited to those described here.

摘要： There is provided a device for measuring a user's oxygen-consumption. The device includes a venturi tube. The venturi tube has a first tapered portion, a second tapered portion that is more tapered compared to the first tapered portion, and a constriction between the portions thereof. The device includes at least one pressure sensor in communication with the constriction and the first tapered portion of the venturi tube. The device includes an oxygen sensor in communication with the constriction and the first tapered portion of the venturi tube.

摘要： Sensor systems are described that are designed to be integrated with gloves for the human hand. An array of sensors detects forces associated with action of a hand in the glove, and associated circuitry generates corresponding control information that may be used to control a wide variety of processes and devices.

摘要： Maintaining functionality in a device reliant on active biocatalysts. A water-impermeable container has one or more biocatalysts mixed and packed with stabilizers to function as a slow-release device. Depending on its adjustable geometries the device will provide a modifiable trickle of biocatalysts into a liquid released from a dry and stable state.

摘要： An apparatus and method is provided for coating a surface of a material with a film of porous coordination polymer. A first substrate having a first surface to be coated is positioned in a processing chamber such that the first surface is placed in a substantially opposing relationship to a second surface. In some embodiments, the second surface is provided by a wall of the processing chamber, and in other embodiments the second surface is provided by a second substrate to be coated. The first substrate is held such that a gap exists between the first and second surfaces, and the gap is filled with at least one reaction mixture comprising reagents sufficient to form the crystalline film on at least the first surface. A thin gap (e.g., having a thickness less than 2 mm) between the first and second surfaces is effective for producing a high quality film having a thickness less than 100 μm. Confining the volume of the reaction mixture to a thin layer adjacent the substrate surface significantly reduces problems with sedimentation and concentration control. In some embodiments, the size, shape, or average thickness of the gap is adjusted during formation of the film in response to feedback from at least one film growth monitor.
