Abstract: An abdominal breathing training apparatus, an abdominal breathing training system and the method thereof are provided. The abdominal breathing training apparatus is adapted for training a trainee how to perform an abdominal breathing and includes a trainer unit, a sensor unit, a data acquisition and conversion unit and a display unit. The trainer unit generates training waveforms and indications. The sensor unit directly measures abdominal movement signals from the trainee, and is positioned adjacent to the abdominal portion of the trainee. The data acquisition and conversion unit is coupled to the sensor unit and generates a trainee abdominal movement waveform according to the measured abdominal movement signals of the trainee. The display unit is coupled to the trainer unit, and displays the training waveforms and the indications to the trainee, who follows the training waveforms on the display unit to perform the abdominal breathing.

Abstract: An overload protection device for LED luminary includes a light bulb connected in front of a circuit that has a single or a group of LED luminaries thereon. The light bulb forms an energy consumption device. The energy consumption device can change the consumption value automatically to protect the LED luminary.

Abstract: An electrical card connector includes an insulating housing having a plurality of passageways and a plurality of contacts received in the insulating housing. Said insulating housing has a plurality of bars near two sides of each passageway for restricting each said contact vertically. Each bar has a barb on an inner side thereof so that the contact can be retained in the insulating housing firmly to prevent the contact from dropping out from the insulating housing.

Abstract: A cable tie includes: a belt body with a gear portion and a through portion. The through portion with a cross-hole forms on one end of the belt body and there is a first against-block and a second against-block forms inside the cross-hole and protrudes in different direction. Those against-blocks can against with the gear on the belt body.

Abstract: An electrical connector (100) used to be mounted on a printed circuit board includes an insulating housing (20) defining a receiving cavity (21) for mating with a complementary component (80), a number of electrical contacts (30) to be soldered to the printed circuit board, an ejecting mechanism assembled to the insulating housing and a metal cover (40) covering the insulating housing (20). The ejecting mechanism includes a slider (60) slidable between a first position and a second position, and a spring (50) for driving the slider to the first position. The metal cover forms a tab (41) at the first position for preventing the slider from moving over the first position under a force that the spring applies to the slider.

Abstract: A card connector with an insulating housing comprising a plurality of passageways; a plurality of contacts received in the passageways of the housing; the housing further receives metal guiding arms, each guiding arm having legs which engage opposite sides of the housing where one of the legs provides for soldered adhesion of each guiding arm to a printed circuit board.

Abstract: A card connector adapted for receiving a card, comprises an insulating housing defining a card receiving space for the card, a plurality of contacts, an ejector for ejecting the card and at least two switch contacts for detecting whether the card is inserted. The ejector comprises a slider defining an original position and a final position, a spring, a holding equipment and a metal plate retained to the slider and moving together with the slider. One of the switch contacts not electrically connecting with the other switch contacts when the slider is at the original position, and all of the switch electrically connecting with each other by simultaneity contacting with the metal plate when the slider is at the final position.

Abstract: A card connector includes an insulating housing (10), a number of contacts (20) and an ejector (30). The insulating housing (10) defines a card receiving space (13) with a card insertion/ejection direction. The contacts (20) are retained in the insulating housing (10) and include a plurality of contacting portions (23) exposed into the card receiving space (13) to electrically connect with a card. The ejector (30) is assembled to the insulating housing (10) includes an ejecting arm (323) exposed into the card receiving space (13) to eject a card. The ejecting arm (323) includes a shield portion (326) extending in the card receiving space (13) along the card ejection direction from a transverse lateral side of the ejecting arm (323) being away from the contacts (20).

Abstract: A card connector adapted for receiving a card comprises an insulating housing (1) defining a card receiving space with a card insertion/ejecting direction; a plurality of contacts (2) retained in the insulating housing and an ejector (3) received in the insulating housing for ejecting the card. The ejector comprises a slider (30) movable along the card insertion/ejecting direction, a resilient member (31), a pin member (32) and a latching member (33) retained to the slider and having a locking portion (330), during an insertion process of the card, the latching member moves upwardly together with the slider, and brings the locking portion to move upwardly and lock the card.

Abstract: A card connector comprises insulating housing comprising a plurality of passageways; a plurality of contacts received in the passageways of the housing; and metal ears received on the housing; wherein the metal ear has legs extends on an upper surface and a bottom surface of the housing respectively to engage the metal ear on the housing and one of the legs is used to solder the metal ear on a PCB.
