Abstract: Disclosed is a method for establishing a prediction model based on a multidimensional texture of brain nuclear magnetic resonance images. Images are segmented using a region growing method, a contourlet transform method is used to extract an edge texture feature parameter of ROIs, a multidimensional database is established, and a prediction model is established using various data mining methods, comprising a Gaussian process, a support vector machine, a random forest, a Lasso regression and a semi-supervised support vector machine. The ROIs comprise a hippocampus region and an entorhinal cortex region.

Abstract: An electrical connector includes an inner shell, an insulating housing, a plurality of terminals disposed in the insulating housing, an insulating jacket and an outer shell. The inner shell is looped from a metal plate to define an accommodating chamber therein and form a joint at a first top plate thereof. Two portions of the first top plate are punched outward to form two hollow receiving hats. The insulating housing is fastened in the accommodating chamber. The insulating jacket includes a first frame substantially airtightly surrounding the inner shell and a covering piece protruded frontward from a front of a top part of the first frame for covering the joint and locating between the receiving hats. The outer shell surrounds and electrically connects with the inner shell. The outer shell has at least one soldering arm soldered to the printed circuit board for achieving a ground function.

Abstract: A card connector includes an insulating housing, a detection terminal, and a shielding shell. The insulating housing defines a card-receiving cavity in a top surface thereof and a channel at a rear portion of a side thereof to communicate with the card-receiving cavity. The detection terminal is mounted to the side of the insulating housing, and has an elastic portion deflected inwardly to enter the card-receiving cavity and a detection portion formed at a free end of the elastic portion. The shielding shell is covered on the insulating housing, and has a flexible strip deflected inwardly to be located at the channel outside the detection terminal. When an electronic card is fully inserted into the card-receiving cavity, the electronic card presses against the detection portion and make the elastic portion deflect outwardly to electrically contact with the flexible strip.

Abstract: An electrical connector adapted to be mounted in an electronic product includes an insulating housing, a plurality of terminals disposed in the insulating housing, a cover and an elastic band. The insulating housing has a front wall extending transversely and a sidewall extending rearward from a portion of the front wall. The sidewall defines a perforation longitudinally penetrating therethrough and further penetrating through the front wall. The cover is welded with a rear end of the sidewall to seal a rear end mouth of the perforation to stop water flowing into the electronic product along the perforation. The elastic band is transversely sleeved around a peripheral outer surface of the front wall to abut against corresponding insides of the electronic product for stopping water from flowing into the electronic product through chinks between the peripheral outer surface of the front wall and the corresponding insides of the electronic product.

Abstract: A card connector includes an insulating housing, a detection terminal unit, and a shielding shell. The insulating housing defines a channel at a rear portion of a first side wall thereof. The detection terminal unit is mounted to the first side wall of the insulating housing and includes a contact terminal and a detection terminal. The contact terminal has a first elastic portion located in the channel and a contact portion formed at a free end of the first elastic portion. The detection terminal has a second elastic portion located inside of the contact terminal and a detection portion formed at a free end of the second elastic portion. When an electronic card is fully inserted into the card connector, the electronic card presses against the detection portion of the detection terminal and makes the detection portion deflect outwardly to electrically contact with the contact portion of the contact terminal.

Abstract: An electrical connector includes an insulating housing and a plurality of electric terminals. The insulating housing defines a plurality of terminal grooves for correspondingly receiving the electric terminals therein. Each of the electric terminals has a welded portion extending outside from a rear of the insulating housing for being soldered to a printed circuit board. A substantially inversed funnel shaped injecting portion is formed at a middle portion of the welded portion for leading liquid-state material to inject therefrom and then flow to the welded portion until the liquid-state material is solidified and integrated with the insulating housing. Therefore, the welded portions are not easily warped while soldered to the printed circuit board. Thus, the welded portions are soldered to the printed circuit board firmly, and the electrical connection between the electrical connector and the printed circuit board is more stable.

Abstract: A memory card connector includes an insulating housing, a plurality of terminals received in the insulating housing, and a shell. The insulating housing has a base. The base defines a first edge, a second edge contiguous to the first edge, a third edge and a fourth edge contiguous to the third edge. The shell has a top plate, a first side plate and a second side plate respectively extending downward from two contiguous margins of the top plate. The shell covers on the insulating housing with the first side plate and the second side plate respectively secured to the first edge and the second edge such that a chamber is formed between the shell and the insulating housing, a first insertion opening is defined between the top plate and the third edge of the insulating housing, and a second insertion opening is defined between the top plate and the fourth edge of the insulating housing.

Abstract: A receptacle connector is adapted to mate with a plug connector having at least one latch. The receptacle connector includes a connector body, a plurality of terminals received in the connector body and at least one dust-proof cover. The connector body defines at least one perforation therethrough. The perforation has a first port from which the latch of the plug connector is received in the perforation, and a second port communicating with the first port. The dust-proof cover is mounted on a rear portion of the connector body to seal the second port of the perforation to prevent dust outside the perforation from entering along the perforation.
