A non-contact printed circuit board (PCB) electromagnetic testing system comprises at least one high resolution transducer operative to induce multi-frequency, multi-amplitude eddy currents in a tested PCB, each such transducer including both a high frequency excitation coil that serves also as a sensing coil and a direct current (DC) bias coil operative to provide an optimal transducer operating regime; a multi-frequency generator for providing AC and DC bias signals to each transducer; and a control mechanism for driving the transducer. Optionally, the system further comprises an external ferrite concentrator that enhances a magnetic field flux focus and depth of focus on the inspected PCB. The multi-frequency, multi-amplitude methods enable three-dimensional mapping of various features in the PCB with both high sensitivity and high resolution in respective operating regimes.

The present invention relates to a vehicle rim with print graphics and methods of making. A rim is provided for a bicycle wheel having an axis about which the wheel rotates and a center plane normal to the axis, including a tire-engaging portion located at an outer perimeter of the rim. An inner perimeter portion is located radially inwardly from the tire-engaging portion. The rim includes a first sidewall and a second sidewall spaced from the first sidewall. The first and second sidewalls extend between the tire-engaging and inner perimeter portions. An image receiving area is located on each of the first and second sidewalls and a non-contact printed graphic is disposed on at least some of the image receiving area.

A multi-channel pressure sensor module (10) for integration in a hydraulic / electrical control unit of a vehicular braking system is shown. A body or manifold (16) mounts a plurality of strain gauge sense element assemblies (12) each having a port for connection to a fluid pressure source to be monitored. An electronic module assembly (14) has a contact printed circuit board (24) and a sense element printed circuit board (22) sandwiching a spacer / support member (20) and electrically coupled together by a flexible circuit board (26). The spacer / support member (20) is formed with pockets (20e, 20f) for receipt of discrete electronic components and to provide access to wire bond pads (22c) and sense element openings (22b). First and second sets of guide posts (20c, 20d) extend from the spacer / support member for alignment of the circuit boards as well as the electronic module assembly on the base. A cover (18) is received on the base over the electronic module assembly and provides access to contact pads of the contact printed circuit board through a shroud (18d).

The present invention discloses a modified method for gear teeth loading contact analysis. The method obtains a tooth surface equation and a normal vector equation of the gear through geometric calculation based on deformation compatibility conditions; and performing gear teeth contact analysis with no load on such basis to obtain contact prints and transmission error by the gear engagement, principal curvature and principal direction of the tooth surfaces, and derivative method curvature of the tangent tooth surfaces, thereby establishing a relation within the size of the contact oval, the amount of compression of the tooth surface, and the load; determining load distribution of the gear by combining with Hertz theoretical formula and a flexibility coefficient method, considering effect from an installing error and a supporting error, and nonlinearity of the contact flexibility coefficient; and according to a load distribution result among the teeth, using the Hertz formula to calculate a tooth surface pressure distribution and a contact stress distribution at a certain moment of the large and small gears, and using a three-dimensional finite element model to perform stress calculation to obtain a reliable bending stress. The gear teeth loading contact analysis method plays an important role in design, calculation and application of the technical field of gears.

A contact printing apparatus (100), using a direct-coupled emissive array (20) of individual light emitting pixels (22), forms an image from digital data onto a photosensitive medium (16). The direct-coupled emissive array (20) is fabricated on an optically coupled substrate (25) that provides light-directing elements, such as a lenslet array or fiber optic faceplate (40) for directing light from emitter pixels (22) to print pixel (71) locations on the photosensitive medium (16).
