Abstract: A method of stripping, prepping and coating a surface comprises first stripping the exiting coating from a surface, using continuous or pulsed fluid jet, followed by prepping the surface by the same fluid jet. The method also provides entraining particles into a fluid stream, if desired to generate a particle-entrained fluid stream that is directed at the surface to be stripped and prepped. The particles act as abrasive particles for prepping the surface to a prescribed surface roughness required for subsequent application of a coating to the surface. The method then entails coating the surface by electrically charging particles having the same chemical composition as the particles used to prep the surface. Finally, a charged-particle-entrained fluid stream is directed at high speed at the charged surface to coat the surface. The particles form both mechanical and electronic bonds with the surface.

Abstract: A method of prepping a surface using a high-frequency forced pulsed waterjet entails generating a high-frequency signal having a frequency f using a high-frequency signal generator, applying the high-frequency signal to a transducer having a microtip to cause the microtip of the transducer to vibrate to thereby generate a forced pulsed waterjet through an exit orifice of a nozzle having an exit orifice diameter d and a length L. The forced pulsed waterjet prepares the surface to within a predetermined range of surface roughness. The surface roughness is determined by selecting operating parameters comprising a standoff distance (SD), a traverse velocity VTR of the nozzle, a water pressure P, a water flow rate Q, a length-to-diameter (L/d) ratio, a microtip-to-orifice distance (a), the frequency f, and an amplitude A of the high-frequency signal.

Abstract: A transceiver module (1) having a release mechanism includes a connector assembly (3), a driving device (43), and a pull tab (45). The connector assembly includes a tab (362) for being received in a hole (242) of a bendable portion (240) of a receptacle (2), which receptacle receives the transceiver module therein. The driving device includes, a release member (42) and a wedge member (46). Both the pull tab and the wedge member are mechanically linked to the release member. When the pull tab is pulled outwardly, the release member rotates with respect to the connector assembly, driving the wedge member to press against the bendable portion of the receptacle, thus disengaging the tab from the hole. The transceiver module is then easily withdrawn from the receptacle. This arrangement allows the transceiver modules to be closely stacked together while still being readily accessible. This advantage decreases a stacking height of multiple transceiver modules.

The RJ connector attaches to the printed circuit board assembly. The engaging clamp provides a stronger, more reliable mechanical connection between the printed circuit board assembly and the RJ connector.
