Abstract:
A status simulation testing method is for use in testing a portable device having at least one angular velocity sensor and includes positioning the portable device on an oblique plane; moving and flinging the portable device at an increasing velocity to enable the portable device to move at an acceleration and an angular velocity; generating a sensing value by the angular velocity sensor of the portable device; and determining whether a sensing operation of the angular velocity sensor of the portable device is functioning well according to the sensing value. Accordingly, the method not only simulates a usage status of the portable device, but also tests the sensor of the portable device quickly, consistently, and accurately. A status simulation testing system is further introduced.

Abstract:
A method for laying out a printed circuit board for use in a gigabit-capable passive optical network includes the steps of providing a printed circuit board and laying out an analog circuit module, an analog-to-digital conversion module, a signal processing module, an optoelectronic transmitting and receiving module, and a power module on the printed circuit board. The printed circuit board has a first periphery and an opposing second periphery. The analog circuit module and the optoelectronic transmitting and receiving module are laid out at the first periphery of the printed circuit board. The power module is laid out at the second periphery of the printed circuit board. Electromagnetic wave generated by a power IC inserted in the power module does not interfere with data transmission taking place at the optoelectronic transmitting and receiving module. Furthermore, a printed circuit board for use with the method is proposed.
Abstract:
A printed circuit board grounding structure for use with a communication apparatus is configured for use with a printed circuit board to contact a grounded casing and thereby form a grounded circuit capable of electromagnetic wave shielding. The printed circuit board ground structure includes a copper conductive layer and a plurality of solder contacts. The copper conductive layer is circumferentially disposed along the periphery of the printed circuit board. The solder contacts are disposed on the copper conductive layer and used for electrically contacting with the casing. The printed circuit board grounding structure prevents deterioration of electromagnetic wave shielding despite oxidation of the copper conductive layer. The circumferentially-disposed copper conductive layer blocks electromagnetic wave generated from inside the printed circuit board, prevents leakage of the electromagnetic wave, and ultimately prevents the electromagnetic wave from interfering with other electronic apparatuses.
Abstract:
A waterproofing method and structure are applicable to an electronic device having a first casing and a second casing, the first casing having a first adjoining-brim peripherally disposed thereon, and the second casing having a peripheral second adjoining-brim for adjoining the first adjoining-brim. The method includes forming a convex portion circumferentially along the first adjoining-brim; forming a concave portion circumferentially along the second adjoining-brim, the concave portion corresponding in position to the convex portion; disposing a resilient unit in the concave portion, the resilient unit including a body and a soft interfering element protruding therefrom; coupling the first and second adjoining-brims together such that the convex portion presses against the soft interfering element to enable deformation thereof, thereby forming a first interfering structure. The waterproof effect achieved by coupling the first and second adjoining-brims together is not compromised by the stress resulting from the deformation of the soft interfering element.

An attachment-enabling jig for attaching a soft strip to an attachment surface of an object quickly, precisely, and flatly includes a base; a first carrying unit disposed on the base and provided with a first roller oriented perpendicular to a first direction; a second carrying unit disposed on the base and provided with a second roller corresponding in position to the first roller, wherein the first and second carrying units carry the soft strip; a resilient unit connected to the first and second carrying units; and an actuating unit disposed on the base and configured to hold the object and controllably drive the attachment surface of the object to move to between the first roller and the second roller such that the first and second rollers attach the soft strip to the attachment surface. Accordingly, the attachment-enabling jig is effective in enhancing the efficiency of production lines.
Abstract:
A latch structure prevents separation of first and second bodies of an electronic device which might otherwise occur as a result of a fall, requires little force to operate, and serves to switch a coupling status of the first and second bodies of the electronic device. The first body has a receiving unit and a coupling unit. The second body has an L-shaped groove. A base of the latch structure has a casing slidable in the receiving unit and a resilient element for providing a resilient restoring force. The casing has a protruding member for coupling with the L-shaped groove. A resilient coupling unit of the latch structure is disposed on the base and configured to engage the coupling unit.
Abstract:
A soft ring addresses issues, such as casing deformation, waterproof capacity, and dust control. The soft ring is configured for use with a casing of an electronic device, and the casing has a first housing and a second housing coupled together. A ring-shaped receiving groove is disposed on the first housing for receiving the soft ring and a ring-shaped flange is disposed on the second housing for pressing the soft ring along the coupling portion of the first housing and the second housing. The soft ring is characterized in that a channel is disposed along the soft ring. The soft ring advantageously features a high compressed capacity and a low reaction force to thereby prevent the casing from deformation and improve the waterproof capacity and dust control of the casing.
