A portable electronic device comprises a motherboard with an electronic component mounted thereon, an electrical conducting port disposed on the motherboard, a heat dissipation plate for dissipating heat of the electronic component, and conductive foam placed between the electrical conducting port and the heat dissipation plate. The heat dissipation plate has a protrusion extending therefrom corresponds to the electrical conducting port. The conductive foam defines a hole, and the protrusion of the heat dissipation plate extends through the hole of the conductive foam to contact the electrical conducting port.

A fastening system is provided that includes a fastener having a pin member with a lock groove and crest geometry that is optimized to receive swaged material from collars of materials of different strengths for securing workpieces for different load applications. The lock grooves have the longest width required for collars of lower strength for one application or greater strength for a second application and the crests have the longest width required for collars of greater strength for the second application whereby satisfactory clamp and tensile loads and resistance to failure will result when the lock grooves are filled with collar materials of different strengths. Certain collars of different materials have similar outside diameters for installation by a tool having a swage anvil with a uniform swage cavity that swages the collars into the lock grooves for securing workpieces in shear, shear/tension, shear composite and shear/tension composite applications.

An optical recording apparatus includes a traverse, a control circuit board, a shield substrate and an flexible flat cable (FFC). The traverse includes a spindle motor for rotating an optical disc and an optical pickup head for reading and/or writing the optical disc, the optical pickup head moves along a radial direction of the optical disc when reading and/or writing the optical disc. The FFC electrically connects the optical pickup head and the control circuit board and transmits signals between them, and a portion of the FFC adjacent to the second end is bent to facing the shield substrate. The shield substrate includes at least two limiting members, and the at least two limiting members are positioned at two opposite sides of the portion of the FFC facing the shield substrate to enable the portion of the FFC facing the shield substrate to move along the first direction.

An exemplary electronic device includes a main housing and a cover pivotably attached to the main housing. The main housing has a printed circuit board received therein. A Hall sensor is fixed and electrically connected to the printed circuit board. The cover has a display and a speaker located adjacent to the display. The speaker includes a magnet. The Hall sensor can detect variation of a magnetic field of the magnet to output different voltages, thereby actuating the display to turn on or turn off.

An exemplary electronic device includes a shell, a circuit board located in an inner side of the shell, a toggle switch positioned on the circuit board, and a slide button. The toggle switch includes a pin. The shell defines a through hole therein. The slide button includes an operating portion located at an outer side of the shell, a curved body extending obliquely from a side of the operating portion. The body of the slide button extends through the through hole of the shell. A distal end of the body of the slide button engages with the pin of the toggle switch. The pin of the toggle switch can be caused to move by moving the slide button.
