Abstract:
A cable connector assembly (100) according to the present invention includes an insulator (2), a PCB (5) and a wire management member (4). The insulator includes a front side, a rear side, a number of terminal passages (24) between the front side and the rear side, and a number of terminals (3) respectively mounted in the terminal passages, each of the terminals has a tail (33) extended out of the rear side of the insulator. The PCB is located behind the insulator and includes a number of first conductive pads (51) which connect with the corresponding terminals and a number of second conductive pads (52) which is soldered to a number of wires (6), the first conductive pads electrically connect with the corresponding second conductive pads. The wire management member is held by the insulator, and defines a number of wire management grooves (421) above the PCB and adjacent to the second conductive pads, the wire management grooves receives the corresponding wires for enabling the wires to be respectively soldered to the second conductive pads.
Abstract:
An audio system and method of generating an amplified audio signal comprises a class-D audio amplifier; and a battery directly connected to the class-D audio amplifier, wherein the direct connection between the battery and the class-D audio amplifier achieves a power efficiency greater than approximately 90%. The audio system may further comprise an analog-to-digital converter (ADC) adapted to digitize an output voltage of the battery and digital signal processing to maintain constant audio volume regardless of the battery voltage drift.
Abstract:
A chair includes a positioning unit that is provided in a receiving portion of an armrest and that includes shorter and taller stop portions. A positioning member is retained movably on a rear side of a backrest, and has one end extending into the receiving portion to abut against a selected one of the stop portions. An operating unit is connected to and is operable to move the positioning member for selectively disengaging and engaging the stop portions. A safety mechanism is provided on the backrest and the operating unit, and is operable in either a limiting state, where the positioning member is unable to move past the taller stop portion, or a non-limiting state, where the positioning member is able to move past the taller stop portion.
Abstract:
An exemplary backlight module includes a light guide plate (12), an illuminator (14), and a frame (16) receiving the light guide plate and the illuminator. The light guide plate includes a light incident surface (122) and has a cutout defined in a corner thereof at one end of the light incident surface. The illuminator is located adjacent to the light incident surface. The frame includes a stopper (166) engagingly received in the cutout such that the stopper blocks movement of the light guide plate toward the illuminator.
Abstract:
Automatic control and fuel saving means for internal combustion engines, comprising: at least one centrifugal speed sensor having at least one pair of flyweights, which flyweights are disposed in the guide tracks on a holder, the said guide tracks are such orientated that the components of the centrifugal forces of the flyweights in the guide track directions substantially match the elastic forces of the spring exerting on the flyweights; a mode shifting device connected to the said speed sensor and to the manual operating mechanisms, the said mode shifting device alternately puts the engine into the automatic control mode by the said speed sensor or into the manual control mode.
Abstract:
A micro-electro-mechanical system (MEMS) microphone package is provided in the present disclosure. The MEMS microphone package includes a circuit board, an electromagnetic shielding cover mounted on the circuit board to define an accommodating space, electronic components received in the accommodating space and electrically connected to the circuit board, and a shielding ring covering a joint between the electromagnetic shielding cover and the circuit board. The shielding ring is configured for preventing electromagnetic waves from entering the accommodating space via the joint between the electromagnetic shielding cover and the circuit board.
